how to make Chicken Parmesan Casserole

Ingredients:

4 cups cooked chicken, shredded (You can use rotisserie chicken to save time.)
2 cups marinara sauce
1 cup grated Parmesan cheese
2 cups shredded mozzarella cheese
2 cups cooked pasta (e.g., penne or rotini)
1 tablespoon olive oil
1 teaspoon Italian seasoning
1 teaspoon garlic powder

Directions:

Preheat the oven to 375°F (190°C).
In a large skillet, heat the olive oil over medium heat. Add the shredded chicken, garlic powder, Italian seasoning, salt, and pepper. Stir to combine and heat for about 5 minutes until warmed through.
In a mixing bowl, combine the cooked pasta, marinara sauce, half of the Parmesan cheese, and half of the mozzarella cheese. Mix well.
Add the seasoned chicken to the pasta mixture and mix until everything is evenly distributed.
Pour the casserole mixture into the greased 9×13-inch baking dish. Spread it evenly.
Top the casserole with the remaining mozzarella and Parmesan cheese.
Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes.
Remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and golden brown.
Once done, take it out of the oven and let it cool for a few minutes. Garnish with fresh basil or parsley, if using.
Serve warm and enjoy!
