Step‑by‑Step Instructions for Creamy Chicken and Spinach Casserole with Cream Cheese
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C) and greasing a 9×13-inch baking dish with olive oil or non-stick spray. This will ensure that your Chicken and Spinach Casserole with Cream Cheese doesn’t stick to the pan during baking, allowing for easy serving and cleanup.
Step 2: Prepare the Chicken
Carefully cut each chicken breast horizontally to create thin cutlets, ensuring even cooking. Use a meat mallet to pound the chicken cutlets to uniform thickness, about ½ inch. This helps the chicken retain moisture while baking and promotes an evenly cooked casserole.
Step 3: Marinate the Chicken
In a large bowl, whisk together olive oil, minced garlic, Italian seasoning, salt, and black pepper. Add the chicken cutlets to the bowl, ensuring they are completely coated. Let the chicken marinate for 15 to 30 minutes, allowing the flavors to permeate and contribute to your savory Chicken and Spinach Casserole with Cream Cheese.
Step 4: Sauté the Spinach
In a skillet over medium heat, add a splash of olive oil and sauté fresh spinach until it wilts, about 2 to 3 minutes. Stir frequently to cook evenly, and then transfer the wilted spinach to a plate to cool slightly before mixing it with the cream cheese. This will enhance the flavor without overcooking the spinach.
Step 5: Mix the Cream Cheese
In a medium bowl, beat the cream cheese until smooth and creamy. Then fold in the sautéed spinach along with half of the mozzarella cheese. This mixture will create a rich, flavorful filling for your casserole, uniting the classic tastes in the Chicken and Spinach Casserole with Cream Cheese.
Step 6: Assemble the Casserole
Arrange the marinated chicken cutlets in the base of the greased baking dish evenly. Spoon the creamy spinach mixture over the chicken, spreading it gently. Finally, sprinkle the remaining mozzarella cheese on top, ensuring an indulgent, gooey layer that will melt beautifully when baked.
Step 7: Bake the Casserole
Place the assembled casserole in the preheated oven and bake for 20 to 30 minutes. Check for doneness by ensuring the chicken reaches an internal temperature of 165°F (75°C) and the cheese is melted and lightly browned on top, creating a deliciously inviting appearance.
Step 8: Rest and Serve
Once baked to perfection, remove the casserole from the oven and let it rest for 5 minutes before slicing. This resting time allows the flavors to settle and makes serving easier. Now you can enjoy a warm, comforting slice of Chicken and Spinach Casserole with Cream Cheese that everyone will love!
