Creating Chicken and Spinach Casserole with Cream Cheese is simple. Follow these steps for a delightful dish:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with olive oil.

2. Prepare the Chicken: If you haven’t already, cook and shred the chicken. You can use leftover rotisserie chicken for added convenience.

3. Sauté Spinach: In a skillet over medium heat, sauté the chopped spinach until it wilts. This usually takes about 3-5 minutes. Set it aside.

4. Mix the Cream Cheese and Sour Cream: In a large bowl, mix the softened cream cheese and sour cream until smooth and creamy.

5. Add Cheese and Seasonings: Stir in the shredded cheddar cheese, grated Parmesan cheese, garlic powder, onion powder, salt, black pepper, and Italian seasoning into the cream cheese mixture until fully incorporated.

6. Combine Mixtures: Fold in the cooked chicken and sautéed spinach. If you want to make the casserole heartier, mix in the cooked pasta at this stage.

7. Transfer to Baking Dish: Pour the chicken and spinach mixture into the prepared baking dish and spread it evenly.

8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes or until the top is bubbly and golden brown.

9. Cool: Once done, remove the casserole from the oven and let it cool for about 5-10 minutes before serving.

10. Serve and Enjoy: Serve the casserole warm and enjoy the comforting combination of flavors!
