Creating Chicken Alfredo Casserole is a straightforward process that anyone can master by following these simple steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C).
2. Cook the Pasta: If you haven’t done so already, cook the pasta according to package instructions until al dente. Drain and set aside.
3. Prepare the Chicken: Use leftover chicken or quickly cook some in a skillet. Dice or shred the chicken into bite-sized pieces.
4. Mix the Sauce: In a large bowl, combine the cooked chicken and pasta. Pour in the Alfredo sauce, garlic powder, Italian seasoning, and black pepper. Stir until everything is well incorporated.
5. Add Cheeses: Fold in half of the mozzarella cheese and half of the Parmesan cheese into the mixture for extra creaminess.
6. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish. Smooth out the top with a spatula.
7. Top with Cheese: Sprinkle the remaining mozzarella and Parmesan cheese evenly over the mixture.
8. Add Breadcrumbs (Optional): If desired, sprinkle breadcrumbs on top for added crunch.
9. Bake: Place in the preheated oven and bake for 25-30 minutes or until the cheese is bubbly and lightly golden.
10. Garnish and Serve: Once out of the oven, let it rest for a few minutes. Sprinkle chopped parsley on top for freshness before serving.
