Name: Chicken and Spinach Casserole with Cream Cheese
Prep time: 15 min
Cook time: 30 min
Total time: 45 min
Ingredients: Boneless, Skinless Chicken Breasts (2 large): Chicken breasts are the ideal choice for this casserole due to their mild flavor and tender texture. When cooked properly, they absorb the flavors of the seasonings and the creamy mixture, becoming juicy and succulent. Cutting the chicken breasts into thinner cutlets ensures even cooking, making the casserole come together quickly.; 2 tablespoons, divided: Olive oil is used to sear the chicken and sauté the spinach. It helps add moisture and flavor, preventing the chicken from becoming dry while it cooks. Olive oil also provides a slight fruity undertone, complementing the other ingredients in the casserole.; 3 cloves, minced: Garlic is a flavor powerhouse that enhances the savory profile of the dish. It adds a wonderful aroma when sautéed with the spinach and infuses the chicken with its bold, aromatic flavor. Garlic is a must-have in most casseroles for depth and complexity.; 1 tablespoon: This blend of dried herbs—typically including oregano, basil, thyme, and rosemary—brings an herby and slightly earthy flavor to the casserole. The seasoning is a classic addition to many Italian-inspired dishes and provides a balanced flavor that pairs well with both the chicken and spinach.; 1/4 teaspoon salt, 1/2 teaspoon black pepper: Salt and pepper are the essential seasonings for bringing out the natural flavors of the chicken and spinach. They help to create a well-rounded and satisfying dish. Be sure to taste the mixture as you go and adjust the seasoning to your liking.; 2 cups: Spinach adds a fresh, earthy note to the casserole. Its slightly bitter flavor balances the richness of the cream cheese and mozzarella. When cooked, spinach wilts down significantly, so 2 cups of fresh spinach will reduce to a much smaller volume, but it still provides an essential boost of flavor and texture.; 8 ounces, softened: Cream cheese is the heart of this casserole’s creamy filling. When mixed with the sautéed spinach, it creates a luscious, smooth base that coats the chicken, making each bite indulgent and rich. Cream cheese also adds a subtle tanginess that contrasts beautifully with the mozzarella and Italian seasoning.; 1 cup shredded, divided: Mozzarella cheese is known for its meltability and mild flavor. It is the perfect choice for this casserole because it becomes wonderfully gooey as it bakes, adding a satisfying texture to the dish. Half of the shredded mozzarella is mixed into the spinach and cream cheese filling, while the remaining half is sprinkled on top for a golden, bubbly crust.; 1/2 cup: Parmesan adds a sharp, nutty flavor that complements the creamy mozzarella. It also helps to enhance the overall flavor profile of the casserole. While not essential, Parmesan cheese is a great addition for anyone who loves the umami richness it provides. If you don’t have Parmesan, you can omit it or substitute with another hard cheese like Pecorino Romano.

Instructions

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). This ensures that the casserole will cook evenly and allows the cheese to melt to perfection. Lightly grease a 9×13-inch baking dish with butter or cooking spray to prevent the casserole from sticking.

Step 2: Prepare the Chicken

Cut the chicken breasts in half horizontally to create four thinner cutlets. This helps the chicken cook more quickly and evenly, ensuring that the casserole bakes in a timely manner. If some pieces are thicker than others, use a rolling pin to pound the thicker ends, ensuring that all pieces are of even thickness.

Next, in a large bowl, whisk together 1 tablespoon of olive oil, minced garlic, Italian seasoning, salt, and black pepper. Add the chicken cutlets to the bowl, tossing them to coat evenly. Cover the bowl and let the chicken marinate in the fridge for 15-30 minutes. This allows the flavors to infuse into the meat, enhancing its taste.

Step 3: Cook the Spinach

While the chicken marinates, heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat. Add the spinach and cook, stirring frequently, until the spinach wilts down. This should take about 2-3 minutes. Once wilted, remove the spinach from the skillet and set it aside.

Step 4: Prepare the Cream Cheese Filling

In a medium bowl, beat the cream cheese until smooth and creamy. Add the wilted spinach, 1/2 cup of shredded mozzarella, and Parmesan cheese (if using). Stir until everything is well combined and smooth. This will form the creamy base that coats the chicken in the casserole.

Step 5: Sear the Chicken (Optional)

If desired, sear the chicken for 1-2 minutes per side in the skillet before baking. This step adds a bit of extra flavor to the chicken but is entirely optional. If you choose not to sear the chicken, simply proceed with placing the raw chicken into the baking dish.

Step 6: Assemble the Casserole

Take the marinated chicken cutlets and arrange them in a single layer in the prepared baking dish. Spread the spinach and cream cheese mixture evenly over the top of the chicken. Sprinkle the remaining 1/2 cup of shredded mozzarella on top of the spinach mixture for that deliciously gooey, golden crust.

Step 7: Bake the Casserole

Place the baking dish in the oven and bake the casserole at 400°F for 20-30 minutes, or until the chicken is fully cooked and the cheese is melted and lightly browned. You can check the internal temperature of the chicken with a meat thermometer—once it reaches 165°F, the casserole is ready.

Step 8: Rest and Serve

Once the casserole is finished baking, remove it from the oven and let it stand for 5 minutes. This resting time allows the casserole to set and makes it easier to slice and serve. Garnish with fresh herbs or additional grated cheese if desired.

Notes

Make It Spicy

If you like a little heat, add some red pepper flakes to the cream cheese mixture or sprinkle hot sauce on top before serving. You can also experiment with different types of spicy cheeses, such as pepper jack, for an extra kick.

Swap the Greens

While spinach works beautifully in this casserole, you can experiment with other greens. Kale or arugula can be used in place of spinach for a slightly different flavor. Just be sure to sauté them until they’re tender before adding them to the cream cheese mixture.

Add Some Vegetables

For a heartier casserole, consider adding some other vegetables to the mix. Mushrooms, zucchini, or sun-dried tomatoes would all work well in this dish. Sauté them along with the spinach or add them to the cream cheese mixture for a pop of flavor and color.

Use Different Cheese

While mozzarella and Parmesan are the go-to cheeses for this casserole, you can swap them out for your favorites. Cheddar cheese would give the dish a sharper, more pronounced flavor, while goat cheese could add a creamy tanginess. Just be sure to use cheeses that melt well for the best texture.

Make It Lighter

To lighten up the dish, consider swapping the cream cheese for a lighter alternative, such as Greek yogurt or light cream cheese. You can also use skinless chicken thighs for a bit more flavor and moisture without the extra fat.
