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 you have the perfect temperature for baking your Chicken Parmesan Casserole later. As the oven warms, you can prepare the other ingredients, making efficient use of your time and setting the stage for that bubbling, cheesy delight.
Step 2: Sauté the Chicken
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Once the oil shimmers, add your shredded cooked chicken along with 1 teaspoon each of garlic powder, Italian seasoning, salt, and pepper. Stir well and cook for about 5 minutes, until the chicken is warmed through and coated in the aromatic spices, filling your kitchen with delicious fragrances.
Step 3: Mix the Pasta and Sauce
In a large mixing bowl, combine 2 cups of cooked pasta with 2 cups of marinara sauce, half of the grated Parmesan cheese, and half of the shredded mozzarella. Stir the mixture gently until all components are well incorporated, ensuring the pasta is evenly coated with the marinara and starting to resemble a comforting, flavorful base for your Chicken Parmesan Casserole.
Step 4: Incorporate the Chicken
Add the sautéed chicken mixture from the skillet to the pasta and sauce blend. Use a spatula to fold the chicken in gently until it’s evenly distributed throughout the pasta. This step is key to achieving that delicious flavor in each bite, allowing the seasoned chicken to mingle with the marinara goodness, making your casserole extra hearty.
Step 5: Transfer to Baking Dish
Grease a 9×13-inch baking dish with a little oil or cooking spray to prevent sticking. Carefully pour the chicken and pasta mixture into the dish, spreading it evenly across the bottom. This ensures that every portion gets just the right amount of gooey cheese and savory chicken when the casserole bakes to perfection.
Step 6: Add the Cheese Toppings
Sprinkle the remaining mozzarella and Parmesan cheese generously over the top of the casserole. This layer of cheese will melt beautifully and provide a deliciously golden, crispy crust as it bakes. Make sure every corner is covered for that ultimate cheesy experience in your Chicken Parmesan Casserole!
Step 7: Bake the Casserole
Cover the baking dish tightly with aluminum foil to trap in moisture, and place it in your preheated oven. Bake for 30 minutes, allowing the flavors to meld beautifully. After 30 minutes, carefully remove the foil to let the cheese become bubbly and golden brown, then return the casserole to the oven for an additional 10 minutes.
Step 8: Garnish and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. This resting time is essential to allow the flavors to settle and the cheese to firm up slightly. Finally, garnish with fresh basil or parsley for a vibrant touch before serving, and enjoy every delightful bite of your homemade Chicken Parmesan Casserole.

How to Store and Freeze Chicken Parmesan Casserole
Fridge: Store leftover Chicken Parmesan Casserole in an airtight container for up to 3 days. Ensure it’s fully cooled before sealing to retain moisture.
Freezer: For longer storage, wrap the casserole tightly in plastic wrap or aluminum foil, then place it in a freezer-safe container. It can be frozen for up to 2 months.
Reheating: When you’re ready to enjoy your casserole again, reheat it in a low oven at 350°F (175°C) covered with foil. This will help restore its delicious texture while keeping the cheese melty.
Thawing: For best results, thaw the casserole overnight in the fridge before reheating. This helps maintain the flavor and prevents it from becoming watery.
Make Ahead Options
These Chicken Parmesan Casserole preparations are perfect for busy weeknights and can save you valuable time! You can assemble the casserole up to 24 hours in advance; simply prep all the ingredients, mix them together, and transfer the mixture to your greased baking dish. Cover and refrigerate to keep it fresh. For the best quality, bake it straight from the fridge when you’re ready to serve, adding about 10 minutes to the cooking time to ensure it reaches the proper temperature. Just remember to bake covered for the first 30 minutes to keep it moist. With these steps, your Chicken Parmesan Casserole will be just as delicious and comforting, making meal prep a breeze!

Chicken Parmesan Casserole Recipe FAQs
How do I choose the right chicken for this casserole?
Absolutely! For the best results, opt for cooked chicken that’s juicy and flavorful. Shredded rotisserie chicken is a fantastic choice, as it saves time and brings a deliciously roasted flavor to your casserole. If you’re using raw chicken, make sure it’s well-seasoned and cooked through before adding it to the dish to ensure a flavorful outcome.
How should I store leftover Chicken Parmesan Casserole?
Leftover Chicken Parmesan Casserole can be stored in an airtight container in the refrigerator for up to 3 days. Make sure it’s fully cooled before sealing to retain moisture and keep that creamy texture. When you’re ready to enjoy leftovers, I recommend reheating in a low oven to maintain the cheese’s gooey quality rather than using a microwave, which can toughen the pasta.
Can I freeze Chicken Parmesan Casserole?
Yes, you can freeze Chicken Parmesan Casserole for up to 2 months. To do this, wrap the casserole tightly in plastic wrap or aluminum foil, then place it in a freezer-safe container. For the best taste and texture, it’s ideal to thaw it overnight in the refrigerator before reheating.
What should I do if the casserole is too dry after baking?
If your casserole turns out dry, it could be due to overbaking or not enough marinara sauce. To troubleshoot, ensure you cover the dish with foil during the first half of baking to keep in moisture. I often recommend checking the casserole after the initial 30 minutes of baking to see if it needs more sauce. Next time, consider adding another layer of marinara sauce or even a splash of chicken broth before baking to ensure it stays moist.
Is this casserole suitable for various dietary needs?
Very! To accommodate dietary preferences, you can easily swap out ingredients. Use gluten-free pasta for a gluten-free version or reduced-fat cheese for a lighter dish. If making this for someone with dairy allergies, try a dairy-free cheese or skip the cheese altogether, and just add more herbs for flavor. Always make sure to double-check ingredient labels for potential allergens, especially if serving to guests with food sensitivities.
