Step‑by‑Step Instructions for Chicken and Spinach Casserole with Cream Cheese
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C) and greasing a 9×13-inch baking dish with a touch of olive oil. This will ensure that your Chicken and Spinach Casserole with Cream Cheese will come out perfectly without sticking. Gather your ingredients and equipment so you’re ready to dive into the cooking process with ease.
Step 2: Marinate the Chicken
Cut the chicken breasts in half horizontally to ensure even cooking, then pound them to uniform thickness. In a bowl, combine the chicken with olive oil, minced garlic, Italian seasoning, salt, and pepper, and let it marinate for 15 to 30 minutes to infuse flavor. As you wait, enjoy the delicious aroma as it begins to mingle in your kitchen.
Step 3: Sauté the Spinach
In a skillet over medium heat, add a drizzle of olive oil and sauté the fresh spinach for about 2-3 minutes, or until wilted. Keep an eye on it; the bright green color will signal when it’s ready. Once done, remove it from the heat and set aside to cool slightly while you prepare the cream cheese mixture.
Step 4: Mix the Filling
In a separate mixing bowl, combine the softened cream cheese with the sautéed spinach and half of the shredded mozzarella. Use a spatula or fork to blend these ingredients until they form a smooth, creamy mixture. The contrast of the bright spinach against the white cream cheese promises a delightful flavor combination for your Chicken and Spinach Casserole with Cream Cheese.
Step 5: Sear the Chicken (Optional)
For an added depth of flavor, sear the marinated chicken in a hot skillet for 1-2 minutes per side until golden brown. This step is optional but enhances the taste and texture of the chicken, making your casserole even more irresistible. Just be sure not to cook it fully, as it will finish cooking in the oven.
Step 6: Assemble the Casserole
Place the marinated chicken in the prepared baking dish, spreading it out evenly. Next, generously spoon the creamy spinach mixture over the chicken, ensuring every piece is well-covered. Finally, sprinkle the remaining mozzarella over the top, creating a delightful, cheesy crust that will melt beautifully during baking.
Step 7: Bake to Perfection
Transfer the casserole to your preheated oven and bake for 20-30 minutes. Keep an eye out for the chicken reaching an internal temperature of 165°F (75°C) and the cheese bubbling and turning a lovely golden brown. This will be your cue that your Chicken and Spinach Casserole with Cream Cheese is ready to come out and be savored.
Step 8: Rest Before Serving
Once baked, remove the casserole from the oven and let it rest for about 5 minutes. This resting period allows the flavors to settle and makes serving easier. After this brief wait, you can slice into this cheesy, creamy masterpiece and pair it with a fresh salad or some roasted veggies for a complete meal.
