Step‑by‑Step Instructions for 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 a bit of olive oil. This step ensures your Chicken and Spinach Casserole with Cream Cheese won’t stick, allowing for an easy serving experience later on. Take a moment to enjoy the anticipation of a delicious meal coming together!
Step 2: Prepare the Chicken
Cut the chicken breasts in half horizontally to create thin cutlets, which will cook more evenly. In a mixing bowl, combine the cutlets with olive oil, minced garlic, Italian seasoning, salt, and pepper. Allow the chicken to marinate for 15-30 minutes, soaking up those delicious flavors as it rests.
Step 3: Sauté the Spinach
In a skillet, heat a tablespoon of olive oil over medium heat. Once the oil is shimmering, add the fresh spinach and sauté for about 2-3 minutes until it is wilted and vibrant green. As the spinach cooks, it will reduce in volume, providing a flavorful base for our casserole. Set the spinach aside to cool.
Step 4: Make the Cream Cheese Mixture
In a mixing bowl, beat the softened cream cheese with a hand mixer or sturdy spoon until it becomes smooth and creamy. Gently fold in the sautéed spinach and half of the mozzarella cheese until well incorporated. This mixture will add a rich, creamy texture to your Chicken and Spinach Casserole with Cream Cheese.
Step 5: Sear the Chicken (Optional)
For extra flavor, heat an oiled skillet over high heat and sear the marinated chicken cutlets for 1-2 minutes on each side. You don’t need to cook them through; just aim for a golden-brown crust. After searing, arrange the chicken in the greased baking dish, creating a flavor foundation for the casserole.
Step 6: Assemble the Casserole
Spread the cream cheese mixture evenly over the chicken cutlets in the baking dish. Make sure to cover the chicken well, allowing all the flavors to meld during baking. Top this creamy layer with the remaining mozzarella cheese, creating a gooey, golden finish that will beckon everyone to the table.
Step 7: Bake the Casserole
Carefully place the assembled casserole into the preheated oven and bake for 20-30 minutes. Look for the cheese to bubble and turn a lovely golden brown while ensuring that the chicken reaches a safe internal temperature of 165°F (75°C). The aroma will fill your kitchen as the casserole cooks!
Step 8: Rest and Serve
Once baked, remove the Chicken and Spinach Casserole with Cream Cheese from the oven and let it rest for about 5 minutes. This rest allows the cheesy layers to set. Serve it warm alongside a crisp salad or roasted vegetables for a delightful meal that will satisfy everyone at your table.
