Chicken and Broccoli Cheesy Casserole

There's nothing quite like a warm, cheesy casserole to bring comfort to your dinner table. Today, I'm sharing a classic Chicken and Broccoli Cheesy Casserole that's creamy, satisfying, and perfect for using up leftover chicken. Follow these steps for a foolproof dish.

Serving: 6 | Prep Time: 15 minutes | Cooking Time: 25 minutes

Ingredients

For the Sauce

• 3 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2 cups whole milk
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/2 teaspoon garlic powder

For the Casserole

• 3 cups cooked shredded chicken (from about 1.5 lbs boneless skinless chicken breasts)
• 2 cups broccoli florets (about 1 small crown)
• 2 cups shredded sharp cheddar cheese (divided)

For the Topping

• 1/2 cup panko breadcrumbs
• 1 tablespoon melted butter

Instructions

1. Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish.
2. Bring a medium pot of salted water to a boil. Add the broccoli florets and cook for exactly 2 minutes, until bright green and slightly tender. Drain immediately and rinse with cold water to stop cooking. Set aside.
3. In a large saucepan over medium heat, melt the 3 tablespoons of butter. Whisk in the flour and cook for 1 minute, stirring constantly, to make a roux. Tip: Do not let it brown; you want a pale paste.
4. Gradually pour in the milk while whisking continuously to prevent lumps. Cook for 3-4 minutes, whisking often, until the sauce thickens and coats the back of a spoon.
5. Remove the saucepan from heat. Stir in the salt, black pepper, garlic powder, and 1½ cups of the shredded cheddar cheese. Whisk until smooth and fully melted. Tip: Reserve the remaining ½ cup of cheese for the topping.
6. In a large mixing bowl, combine the shredded chicken, blanched broccoli, and the cheese sauce. Stir gently until everything is evenly coated.
7. Transfer the mixture to the prepared baking dish and spread it into an even layer.
8. In a small bowl, mix the panko breadcrumbs with the 1 tablespoon of melted butter until crumbly. Sprinkle the breadcrumb mixture evenly over the casserole, then top with the remaining ½ cup of shredded cheddar cheese.
9. Bake for 20-25 minutes, until the casserole is bubbly around the edges and the topping is golden brown. Let it rest for 5 minutes before serving. Tip: For an extra-browned crust, broil for the last 1-2 minutes, but watch closely to avoid burning.

Zesty with a golden cheesy crust, this casserole is pure comfort in every bite. Serve it alongside a simple green salad or crusty bread for a complete meal. Leftovers reheat beautifully for lunch the next day!

Beef Taco Casserole with Cornbread Topping

Wondering what to do with ground beef for a weeknight dinner? This Beef Taco Casserole with Cornbread Topping layers seasoned beef, black beans, and corn under a fluffy cornbread crust for a Tex-Mex twist on comfort food. It's a complete meal in one dish, perfect for busy evenings.

Serving: 6 | Prep Time: 15 minutes | Cooking Time: 35 minutes

Ingredients

For the beef filling

• 1 lb ground beef
• 1 tbsp olive oil
• 1 small onion, diced
• 2 cloves garlic, minced
• 1 packet (1 oz) taco seasoning
• 1 can (15 oz) black beans, drained and rinsed
• 1 can (15 oz) corn, drained
• 1 can (10 oz) diced tomatoes with green chiles
• 1/2 cup sour cream
• 1 cup shredded cheddar cheese

For the cornbread topping

• 1 box (8.5 oz) cornbread mix
• 1/3 cup milk
• 1 large egg
• 2 tbsp melted butter

Instructions

1. Preheat oven to 400°F.
2. Heat olive oil in a large skillet over medium-high heat. Add ground beef and cook, breaking it apart, until browned, about 5–7 minutes. Tip: Don't overcrowd the pan; work in batches if needed to get a good sear.
3. Add diced onion and minced garlic to the skillet; cook 2 minutes until softened.
4. Sprinkle taco seasoning over the beef mixture and stir to coat. Cook 1 minute until fragrant.
5. Stir in drained black beans, drained corn, and diced tomatoes with green chiles. Bring to a simmer, then remove from heat.
6. Stir in sour cream until well combined.
7. Transfer the beef mixture to a 9×13-inch baking dish. Spread evenly.
8. Sprinkle shredded cheddar cheese over the top.
9. In a medium bowl, combine cornbread mix, milk, egg, and melted butter. Stir just until moistened; do not overmix. Tip: Overmixing makes cornbread tough; a few lumps are fine.
10. Spoon the cornbread batter evenly over the beef mixture, spreading gently to cover.
11. Bake for 20–25 minutes, until the cornbread is golden brown and a toothpick inserted into the center comes out clean. Tip: Let the casserole rest for 5 minutes before serving to set the layers.

How about serving this casserole with a dollop of sour cream and fresh cilantro? The cornbread soaks up the savory juices while staying tender, and the crispy edges add a delightful contrast. It's a crowd-pleaser that comes together in one dish, and leftovers reheat beautifully for lunch the next day.

2. Cook the egg noodles in a large pot of salted boiling water according to package directions until al dente. Drain well. Tip: Undercook by 1 minute since they'll continue cooking in the oven.
3. In a large mixing bowl, combine the drained tuna, frozen peas, condensed cream of mushroom soup, milk, half of the shredded cheddar cheese, salt, and black pepper. Stir until thoroughly mixed.
4. Add the cooked noodles to the tuna mixture and fold gently with a spatula until every noodle is coated in the creamy sauce.
5. Transfer the noodle mixture to the prepared baking dish and spread it into an even layer.
6. In a small bowl, mix the breadcrumbs with the melted butter and grated Parmesan cheese until the crumbs are evenly moistened.
7. Sprinkle the breadcrumb mixture evenly over the casserole. Then top with the remaining shredded cheddar cheese.
8. Bake for 25–30 minutes, until the sauce is bubbling around the edges and the topping is golden brown. Tip: For extra crunch, broil for the last 2 minutes, watching carefully to avoid burning.
9. Remove from the oven and let rest for 5 minutes before serving. This helps the casserole set for cleaner slices.

The finished casserole is luxuriously creamy with a crunchy, cheesy topping and sweet pops of peas. Serve it straight from the dish for a comforting meal that’s perfect any night of the week. You can also add a squeeze of lemon or a dash of hot sauce for brightness.

Sausage and Kale Casserole with Sweet Potatoes

This savory casserole features smoked sausage, tender kale, and caramelized sweet potatoes for a comforting one-dish meal. Perfect for busy weeknights, it comes together with simple ingredients and straightforward steps.

Serving: 6 | Prep Time: 20 minutes | Cooking Time: 45 minutes

Ingredients

For the Sweet Potatoes

• 2 large sweet potatoes, peeled and cut into 1/2-inch cubes
• 2 tablespoons olive oil
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper

For the Sausage and Kale

• 1 lb smoked sausage (such as kielbasa), sliced into 1/2-inch rounds
• 1 tablespoon olive oil
• 1 medium onion, diced
• 2 cloves garlic, minced
• 4 cups chopped kale (stems removed)
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper
• 1/4 teaspoon red pepper flakes (optional)

For the Casserole

• 1/2 cup chicken broth

Instructions

1. Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
2. In a mixing bowl, combine sweet potato cubes with 2 tablespoons olive oil, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Toss well to coat evenly. Spread the cubes in a single layer on the prepared baking sheet, ensuring they are not overcrowded. Roast for 20-25 minutes, flipping halfway through, until tender and golden brown. (Tip: Cutting the sweet potatoes into uniform cubes ensures they cook at the same rate.)
3. While the sweet potatoes roast, heat 1 tablespoon olive oil in a large skillet over medium heat. Add the sliced smoked sausage in a single layer and cook until browned on both sides, about 2 minutes per side. Use a slotted spoon to transfer sausage to a plate and set aside.
4. In the same skillet, add diced onion and cook until softened, about 3 minutes, stirring occasionally. Add minced garlic and cook for 1 minute until fragrant.
5. Add the chopped kale to the skillet in handfuls, stirring after each addition until it wilts down. Once all kale is added, continue cooking for 3-4 minutes until tender. Season with 1/2 teaspoon salt, 1/4 teaspoon black pepper, and optional red pepper flakes. (Tip: Massaging the kale with a little olive oil before cooking helps it wilt faster and reduces bitterness.)
6. In a 9×13-inch baking dish, combine the roasted sweet potatoes, cooked sausage, and kale mixture. Pour the chicken broth evenly over the top and stir gently to combine all ingredients.
7. Bake the casserole for 15-20 minutes, or until heated through and the top is slightly crispy. Remove from oven and let rest for 5 minutes before serving. (Tip: Letting the casserole rest allows the flavors to meld and makes serving easier.)

Pour a glass of your favorite red wine and enjoy this hearty, flavorful casserole. The sweetness of the potatoes balances the smoky sausage perfectly. It's even better the next day!

Vegetarian Lentil and Rice Casserole

Unfortunately, many plant-based casseroles turn out mushy or bland. But this lentil and rice casserole is different—each grain stays distinct, and the herb-infused tomato sauce brings depth. Let's build it step by step.

Serving: 6 | Prep Time: 20 minutes | Cooking Time: 45 minutes

Ingredients

For the Lentil and Rice Base

• 1 cup brown lentils, rinsed
• 3/4 cup long-grain brown rice, rinsed
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 2 tablespoons olive oil

For the Tomato Herb Sauce

• 1 can (15 ounces) diced tomatoes, undrained
• 2 tablespoons tomato paste
• 2 cups water or vegetable broth
• 1 teaspoon dried oregano
• 1/2 teaspoon dried thyme
• 1 teaspoon salt
• 1/2 teaspoon black pepper

Instructions

1. Preheat your oven to 375°F. Position a rack in the center.
2. Rinse the lentils and brown rice separately in a fine-mesh strainer under cold water. Tip: Rinsing removes excess starch and dust, preventing gummy results.
3. In a large oven-safe Dutch oven or deep skillet, heat olive oil over medium heat. Add diced onion and cook, stirring occasionally, until translucent, about 3–4 minutes.
4. Add minced garlic and cook for 1 minute, until fragrant. Do not let it brown.
5. Pour in rinsed lentils, brown rice, diced tomatoes with their juices, tomato paste, water (or broth), oregano, thyme, salt, and pepper. Stir well to combine. Tip: The tomato paste dissolves faster if you stir it into the liquid first.
6. Increase heat to high and bring to a boil. Once boiling, reduce heat to low, cover with a tight-fitting lid, and simmer for 20 minutes. The rice and lentils will still be slightly firm.
7. If your pot is oven-safe, keep it covered and transfer directly to the oven. If not, transfer the mixture to a 9×13 inch baking dish and cover tightly with foil.
8. Bake covered for 25 minutes. Then remove the lid or foil and bake for an additional 10 minutes, until the top is golden and most of the liquid is absorbed. Tip: For a crispier top, switch to broil for the last 2 minutes, watching closely.
9. Remove from the oven and let rest for 5 minutes before serving. This allows the casserole to set and flavors to meld.

Crack the crust with a spoon to reveal tender lentils and rice that have absorbed all the savory tomato goodness. Serve with a side salad or roasted vegetables for a complete meal. Leftovers reheat beautifully, making this a perfect meal prep dish.

2. In a medium bowl, combine the shredded chicken, diced onion, minced garlic, cumin, chili powder, salt, pepper, and sour cream. Stir until well mixed. (Tip: Use rotisserie chicken to save time.)
3. Spread about 1/2 cup of enchilada sauce on the bottom of the prepared baking dish to prevent sticking.
4. Arrange 4 tortillas over the sauce, overlapping as needed to cover the bottom.
5. Layer half of the chicken mixture over the tortillas, then sprinkle with 1 cup of shredded cheese.
6. Pour 1/3 of the remaining enchilada sauce over the cheese and spread evenly.
7. Repeat layers: 4 tortillas, remaining chicken mixture, 1 cup cheese, and another 1/3 of the sauce.
8. Top with the remaining 4 tortillas, then pour the rest of the sauce over them. Sprinkle the remaining 1 cup cheese on top. (Tip: For extra browning, broil for the last 2 minutes.)
9. Cover the dish with aluminum foil and bake for 20 minutes. Then remove foil and bake for an additional 10 minutes, until the cheese is melted and bubbly.
10. Let the casserole rest for 5 minutes before slicing. This helps the layers set.

A warm, bubbly casserole straight from the oven is pure comfort. Each bite delivers tender chicken, soft tortillas, and gooey cheese. Serve with a dollop of sour cream and a sprinkle of fresh cilantro for a bright finish.

Pork and Apple Casserole with Cider Glaze

Often overlooked as a one-pot wonder, this pork and apple casserole brings together tender pork shoulder, sweet apples, and a tangy cider glaze for a comforting meal. You’ll build deep flavor step by step, from searing the meat to slow-baking everything until fork-tender.

Serving: 6 | Prep Time: 20 minutes | Cooking Time: 2 minutes

Ingredients

For the Pork and Apples

• 2 lbs pork shoulder, cut into 2-inch cubes
• 2 tbsp olive oil
• 1 tsp salt
• 1/2 tsp black pepper
• 3 medium apples (such as Granny Smith), peeled, cored, and cut into wedges
• 1 large onion, sliced
• 3 cloves garlic, minced

For the Cider Glaze

• 1 cup apple cider
• 2 tbsp apple cider vinegar
• 2 tbsp brown sugar
• 1 tbsp Dijon mustard
• 1 tsp dried thyme

Instructions

1. Preheat your oven to 325°F.
2. Pat the pork shoulder cubes dry with paper towels. Season evenly with salt and pepper.
3. Heat olive oil in a large Dutch oven over medium-high heat. Working in batches to avoid overcrowding, sear the pork on all sides until deeply browned, about 3-4 minutes per batch. Transfer seared pork to a plate.
4. Reduce heat to medium. Add sliced onion to the pot and cook, stirring occasionally, until softened and lightly browned, about 5 minutes. Add minced garlic and cook for 30 seconds until fragrant.
5. In a small bowl, whisk together apple cider, apple cider vinegar, brown sugar, Dijon mustard, and dried thyme to make the glaze.
6. Return the pork to the pot. Pour the cider glaze over the pork and stir to coat. Nestle the apple wedges into the liquid around the pork. Bring the mixture to a simmer on the stovetop.
7. Cover the Dutch oven with a tight-fitting lid and transfer to the preheated oven. Bake for 2 hours. The pork should be fork-tender. (Tip: Check the internal temperature of the pork; it should reach at least 190°F for shreddable tenderness.)
8. Remove the lid and increase oven temperature to 400°F. Continue baking uncovered for 15-20 minutes, until the liquid thickens into a glossy glaze and the apples are caramelized. (Tip: If you prefer a thicker glaze, you can simmer the liquid on the stovetop after baking.)
9. Remove from oven and let rest for 5 minutes before serving. (Tip: Skim off any excess fat from the surface with a spoon before plating.)

Perfect for a chilly evening, this casserole pairs beautifully with mashed potatoes or crusty bread to soak up the glaze. The tender pork, sweet-tart apples, and savory cider notes create a balanced, comforting dish that tastes even better the next day.

When you're looking for a comforting Southern classic, this Shrimp and Grits Casserole is the answer. Creamy grits, sharp cheddar, crispy bacon, and tender shrimp bake together into a one-dish meal that's perfect for family dinners or special brunches. Let's build it step by step.

Serving: 8 | Prep Time: 20 minutes | Cooking Time: 45 minutes

Ingredients

For the Grits

• 2 cups water
• 2 cups whole milk
• 1 teaspoon salt
• 1 cup quick-cooking grits
• 2 tablespoons unsalted butter

• 1/2 cup diced bell pepper
• 1/4 teaspoon cayenne pepper
• 1/2 cup low-sodium chicken broth
• 1 tablespoon fresh lemon juice
• 2 green onions (sliced, for garnish)

Instructions

1. Preheat your oven to 375°F. Grease a 9×13-inch baking dish with butter or nonstick spray.
2. In a large saucepan, bring 2 cups water, 2 cups milk, and 1 teaspoon salt to a boil over medium-high heat. (Tip: Use whole milk for the creamiest grits; low-fat will be less rich.)
3. Slowly whisk in 1 cup quick-cooking grits, reduce heat to low, and simmer for 5 minutes, stirring occasionally, until thickened.
4. Remove from heat. Stir in 2 tablespoons butter and 1 cup shredded cheddar cheese until melted and smooth. Set aside.
5. In a large skillet, cook 6 slices chopped bacon over medium heat until crispy, about 6 minutes. Use a slotted spoon to transfer bacon to a paper towel-lined plate. Leave 2 tablespoons drippings in the skillet.
6. Add 1 small diced onion and 1/2 cup diced bell pepper to the skillet. Cook over medium heat for 4 minutes, until softened. Add 2 minced garlic cloves and 1/4 teaspoon cayenne; cook 1 minute more. (Tip: If you can't handle heat, reduce cayenne to 1/8 teaspoon or omit entirely.)
7. Stir in 1/2 cup chicken broth and bring to a simmer. Add 1 pound peeled shrimp; cook 2 to 3 minutes until just pink and opaque. Do not overcook—shrimp will continue cooking in the oven. Remove from heat and stir in 1 tablespoon lemon juice.
8. Pour the prepared grits into the greased baking dish. Spread evenly. Spoon the shrimp mixture (including all the liquid) over the grits. Sprinkle the reserved cooked bacon on top, then scatter the remaining 1 cup cheddar cheese over everything.
9. Bake uncovered for 20 to 22 minutes, until the casserole is bubbly and the cheese is melted and lightly golden. (Tip: Place a baking sheet on the lower rack to catch any drips—this keeps your oven clean.)
10. Let the casserole rest on a wire rack for 5 minutes before serving. This allows the grits to set and makes serving cleaner.

Remove from the oven and garnish with sliced green onions. The top is golden and cheesy, the grits are velvety smooth, and every spoonful brings the smoky bacon, sweet shrimp, and sharp cheddar together. Serve it with a side of hot sauce for extra kick, or pair with a simple green salad to balance the richness.

Serving: 6 | Prep Time: 20 minutes | Cooking Time: 45 minutes

Ingredients

For the Wild Rice

• 1 cup wild rice, rinsed
• 3 cups water
• 1/2 tsp salt

For the Chicken and Mushrooms

• 1 1/2 lbs boneless skinless chicken breasts, cut into 1-inch cubes
• 1 tbsp olive oil
• 8 oz cremini mushrooms, sliced
• 1 small onion, diced

• 2 cups chicken broth
• 1 cup heavy cream
• 1 tsp dried thyme
• 1/2 cup grated Parmesan cheese

For Topping (optional)

• 1/2 cup panko breadcrumbs
• 2 tbsp melted butter

Instructions

1. In a medium saucepan, combine the wild rice, water, and 1/2 teaspoon salt. Bring to a boil, then reduce heat to low, cover, and simmer for 45 minutes, or until the rice is tender and has absorbed the liquid. Drain any excess water and set aside. Tip: Rinsing the wild rice before cooking removes bitterness and helps it cook evenly.
2. While the rice cooks, heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the cubed chicken and cook, stirring occasionally, until golden brown and cooked through (about 5-7 minutes). Transfer the chicken to a plate and set aside. Tip: Don't overcrowd the pan; cook in batches if needed for proper browning.
3. In the same skillet, add the sliced mushrooms and diced onion. Cook over medium heat, stirring occasionally, until the mushrooms are golden and the onion is translucent, about 5 minutes. Add the minced garlic and cook for 1 minute more. Season with 1/2 teaspoon salt and 1/4 teaspoon pepper.
4. Reduce the heat to medium-low. Add 3 tablespoons butter to the skillet and let it melt. Sprinkle the flour over the vegetables and stir constantly for 1 minute to cook the flour. Gradually whisk in the chicken broth, then the heavy cream, stirring until smooth. Add the dried thyme and bring the mixture to a gentle simmer. Cook for 2-3 minutes, until the sauce thickens. Remove from heat and stir in the Parmesan cheese until melted. Tip: Whisk continuously to avoid lumps.
5. Preheat your oven to 375°F. In a large bowl, combine the cooked wild rice, cooked chicken, and the mushroom-cream sauce. Stir until evenly mixed. Transfer the mixture to a 9×13-inch baking dish, spreading it evenly.
6. If using the topping, mix the panko breadcrumbs with 2 tablespoons melted butter and sprinkle over the casserole. Bake for 20-25 minutes, until the casserole is bubbly and the topping is golden brown. Let it rest for 5 minutes before serving. Tip: For a dairy-free version, substitute the heavy cream with full-fat coconut milk and use a dairy-free butter alternative.

Umami-rich and creamy, this casserole has a delightful nuttiness from the wild rice and a satisfying crunch from the breadcrumb topping. Serve it straight from the dish with a side of steamed green beans or a crisp green salad for a complete meal.

Cheesy Broccoli and Cauliflower Casserole

Let me show you how to make a low-carb, three-cheese broccoli and cauliflower casserole that's creamy, cheesy, and perfect for weeknights. This method ensures the vegetables stay tender and the sauce is silky smooth.

Serving: 6 | Prep Time: 15 minutes | Cooking Time: 30 minutes

Ingredients

For the Vegetables

• 4 cups broccoli florets (about 1 large head)
• 4 cups cauliflower florets (about 1 medium head)
• 1 tablespoon olive oil
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper

For the Three-Cheese Sauce

• 4 ounces cream cheese, softened
• 1/2 cup heavy cream
• 2 cloves garlic, minced
• 1 cup shredded sharp cheddar cheese
• 1 cup shredded mozzarella cheese
• 1/4 teaspoon salt
• 1/8 teaspoon cayenne pepper (optional)

For the Topping

• 1/2 cup shredded Parmesan cheese

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with nonstick spray.
2. Bring a large pot of salted water to a boil. Add the broccoli and cauliflower florets and blanch for exactly 2 minutes. Drain immediately and transfer to a bowl of ice water to stop cooking. Drain again and pat dry with a clean kitchen towel—removing excess moisture prevents a watery casserole.
3. In a large skillet over medium heat, warm the olive oil. Add the blanched vegetables, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Sauté for 2 minutes, stirring occasionally, until just tender. Spread them evenly in the prepared baking dish.
4. In the same skillet (off heat), combine the softened cream cheese, heavy cream, and minced garlic. Whisk until smooth. Return to medium-low heat and stir constantly until the cream cheese is fully melted and the mixture is hot, about 2 minutes.
5. Reduce heat to low. Add the shredded cheddar and mozzarella a handful at a time, stirring after each addition until melted. Season with 1/4 teaspoon salt and cayenne if using. The sauce should be thick and smooth—if it seems too thick, add a splash of heavy cream.
6. Pour the cheese sauce evenly over the vegetables in the baking dish. Use a spatula to gently spread it so all florets are coated. Sprinkle the Parmesan cheese over the top.
7. Bake on the middle rack for 20–25 minutes, until the sauce is bubbly and the top is golden brown. For extra browning, switch to broil for the last 1–2 minutes, watching closely to avoid burning.
8. Let the casserole rest for 5 minutes before serving. This allows the sauce to set slightly and makes portioning easier.

Every forkful delivers tender florets wrapped in a velvety, three-cheese sauce with a crisp Parmesan crust. For a complete low-carb meal, serve it alongside grilled chicken or a simple green salad. Enjoy it while it's hot, and don't be surprised if it disappears fast.

10. Let the casserole rest for 5 minutes before serving. Garnish with fresh cilantro if desired.

Each bite delivers a hearty, cheesy, slightly spicy comfort that's balanced by the tender rice and juicy beef. Serve with a dollop of sour cream and fresh salsa for extra kick, or spoon it over a bed of crisp lettuce for a Tex-Mex taco salad. This casserole also freezes beautifully, making it a great meal prep option for busy weeks.

Lemon Chicken and Orzo Casserole

Preparing this bright and comforting Lemon Chicken and Orzo Casserole is easier than you think. With tender chicken, zesty lemon, and creamy feta, it’s a complete meal baked in one dish. Let’s walk through it step by step.

Serving: 6 | Prep Time: 20 minutes | Cooking Time: 40 minutes

Ingredients

For the Chicken

• 1½ lbs boneless, skinless chicken breasts
• 2 tablespoons olive oil
• ½ teaspoon salt
• ¼ teaspoon black pepper

For the Casserole Base

• 1 cup dry orzo
• 1 tablespoon olive oil
• 1 medium onion, diced
• 3 cloves garlic, minced
• 4 cups fresh spinach
• 2 cups low-sodium chicken broth
• 1 lemon (zest and juice)
• 1 teaspoon dried oregano

For the Topping

• ½ cup crumbled feta cheese
• 2 tablespoons fresh dill (optional)

Instructions

1. Preheat your oven to 375°F. Pat the chicken breasts dry with paper towels, then season both sides with salt and pepper. (Tip: Drying the chicken ensures a nice sear.)
2. In a large oven-safe skillet or Dutch oven, heat 2 tablespoons of olive oil over medium-high heat. Add the chicken and cook for 4-5 minutes per side until golden brown. (It doesn't need to be cooked through – it will finish in the oven.) Remove the chicken to a plate.
3. In the same skillet, add 1 tablespoon olive oil and the diced onion. Sauté for 3 minutes until softened. Add the minced garlic and cook for 30 seconds until fragrant.
4. Add the dry orzo to the skillet and stir for 1-2 minutes until lightly toasted. (Tip: Toasting the orzo adds nutty flavor and helps it hold its shape.)
5. Pour in the chicken broth and scrape up any brown bits from the bottom. Stir in the lemon zest and juice, dried oregano, and a pinch of salt and pepper.
6. Add the fresh spinach in handfuls, stirring until wilted, about 2 minutes.
7. Return the chicken to the skillet, nestling it into the orzo mixture. Sprinkle the crumbled feta cheese evenly over the top.
8. Transfer the skillet to the preheated oven and bake, uncovered, for 25-30 minutes, until the orzo is tender and the chicken is cooked through (internal temperature 165°F). (Tip: If the top browns too quickly, tent with foil.)
9. Remove from the oven and let rest for 5 minutes. Garnish with fresh dill if desired.

Once baked, the orzo becomes tender and creamy from absorbing the broth, while the feta forms delicious golden pockets on top. The lemon brightens every bite, and the spinach adds a pop of green. Serve it straight from the skillet for a rustic presentation, or spoon into bowls with a side of crusty bread.
