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). While it heats, grease a 9×13-inch baking dish to prevent sticking and ensure an easy cleanup. This casserole’s creamy goodness deserves a warm, welcoming baking environment where flavors meld beautifully.
Step 2: Marinate the Chicken
Take your chicken breasts and slice them horizontally to create thin cutlets, which will cook evenly. In a bowl, combine olive oil, minced garlic, Italian seasoning, salt, and black pepper, then add the chicken. Allow this to marinate for 15-30 minutes, letting the flavors infuse into the meat.
Step 3: Sauté the Spinach
In a medium skillet over medium heat, drizzle a bit of olive oil and add your fresh spinach. Sauté the spinach for about 2-3 minutes or until it wilts completely, turning a vibrant green. Once done, remove it from the heat and set it aside, ready to join the creamy mixture.
Step 4: Create the Creamy Mixture
In a mixing bowl, beat the cream cheese until it becomes smooth and creamy. Gradually fold in the sautéed spinach along with half a cup of shredded mozzarella cheese. This mixture should be rich and velvety, providing the comforting base for your Chicken and Spinach Casserole with Cream Cheese.
Step 5: Optional Chicken Searing
For an extra layer of flavor, consider searing the marinated chicken cutlets in your skillet for 1-2 minutes on each side. This step is optional but will add a lovely golden-brown crust that enhances the overall taste of the casserole.
Step 6: Assemble the Casserole
In your greased baking dish, lay the marinated chicken cutlets evenly across the bottom. Spoon the creamy spinach mixture generously over each piece, making sure to cover them well. Finish by sprinkling the remaining mozzarella cheese on top, creating a gooey, irresistible layer.
Step 7: Bake to Perfection
Place the assembled casserole in the preheated oven and bake for 20-30 minutes. Look for bubbly cheese and a golden crust as indicators of doneness. Use a meat thermometer to ensure the chicken reaches an internal temperature of 165°F (75°C) for safe serving.
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 resting period allows the flavors to settle and the juices to redistribute, ensuring each bite is perfect. Serve with a fresh salad or roasted vegetables for a delightful meal.

What can I do if my casserole is too watery?
If you find your Chicken and Spinach Casserole is too watery, it’s likely due to excess moisture in the spinach or from other ingredients. Always be sure to drain frozen spinach well and avoid adding too much liquid during preparation. You can also try baking it a little longer to allow some moisture to evaporate for a thicker consistency.
Is this casserole suitable for gluten-free diets?
Yes, the Chicken and Spinach Casserole with Cream Cheese is naturally gluten-free, provided you use certified gluten-free ingredients. For extra assurance, double-check all labels on your cream cheese and seasonings to ensure they don’t contain any hidden gluten additives.
