Step‑by‑Step Instructions for Chicken Parmesan Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This ensures that the Chicken Parmesan Casserole bakes evenly and achieves that perfect bubbly, golden cheese topping. Let your oven heat up while you prepare the other ingredients; you want it ready when it’s time to bake!
Step 2: Sauté the Chicken
In a large skillet over medium heat, add 1 tablespoon of olive oil. Once hot, toss in the shredded cooked chicken along with 1 teaspoon of garlic powder, 1 teaspoon of Italian seasoning, and salt and pepper to taste. Stir well and heat for about 5 minutes until warm, allowing the flavors to meld beautifully.
Step 3: Mix the Casserole Base
In a mixing bowl, combine 2 cups of cooked pasta (like penne or rotini), 2 cups of marinara sauce, and half of your cheeses (1 cup grated Parmesan and 1 cup shredded mozzarella). Stir thoroughly to ensure that the pasta is evenly coated in sauce. This creamy mixture forms the hearty base of your Chicken Parmesan Casserole.
Step 4: Combine with Chicken
Fold your sautéed chicken mixture into the pasta and sauce blend. Mix carefully, ensuring the chicken is evenly distributed throughout the pasta. This integral step helps the Chicken Parmesan Casserole achieve its signature flavor, blending each element together perfectly.
Step 5: Transfer to Baking Dish
Grease a 9×13-inch baking dish with a little oil or cooking spray. Pour the combined Chicken Parmesan Casserole mixture into the dish, spreading it evenly with a spatula. This ensures every serving cooks uniformly and allows the cheesy top to form a delightful crust.
Step 6: Top with Cheese
Sprinkle the remaining mozzarella and Parmesan cheese generously over the casserole. Make sure the cheese is evenly spread to ensure it melts beautifully and creates that irresistible cheesy topping. This final flourish is what brings the comforting Chicken Parmesan Casserole to life!
Step 7: Bake the Casserole
Cover the dish with aluminum foil and place it in the preheated oven. Bake for 30 minutes, allowing the flavors to meld and the casserole to heat through. After that, remove the foil and bake for an additional 10 minutes until the cheese is bubbly and golden brown—a sight to behold!
Step 8: Serve and Enjoy
Once out of the oven, let your Chicken Parmesan Casserole rest for a few minutes. This resting period allows the juices to redistribute, enhancing the overall texture. Just before serving, you can garnish with fresh basil or parsley for a pop of color and extra flavor. Enjoy your warm, comforting creation!

Make Ahead Options
This Chicken Parmesan Casserole is a fantastic meal prep option, perfect for busy weeknights! You can prepare the entire casserole up to 24 hours in advance by following the instructions until just before baking.

When you’re ready to enjoy, remove it from the fridge, allow it to sit at room temperature for about 30 minutes, then bake as directed—just as comforting and flavorful! This means less stress and more time to spend with loved ones while savoring every bite of your Chicken Parmesan Casserole.

Even Shredding: Ensure your chicken is shredded uniformly for consistent heating. This prevents some pieces from being dry while others remain moist.
