Step‑by‑Step Instructions for Chicken Parmesan Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C) to create the perfect environment for baking the Chicken Parmesan Casserole. This temperature will help develop a crispy top while ensuring the cheese melts beautifully. While the oven heats, gather your ingredients and have your 9×13-inch baking dish greased and ready for the upcoming layers.
Step 2: Sauté the Chicken Mixture
In a large skillet, drizzle about 2 tablespoons of olive oil over medium heat. Add the shredded rotisserie chicken and sprinkle in the Italian seasoning and garlic powder. Sauté for approximately 5-7 minutes, stirring occasionally until everything is well combined and fragrant, and the chicken is heated through. This step infuses the chicken with savory flavor and gets it ready for the casserole.
Step 3: Combine the Casserole Ingredients
In a large mixing bowl, combine the cooked pasta, marinara sauce, half of the grated Parmesan cheese, and the sautéed chicken mixture. Stir everything together until well-mixed, ensuring each pasta piece is coated with sauce and flavor. This rich blend is what makes the Chicken Parmesan Casserole so comforting and delicious.
Step 4: Layer the Casserole
Pour the combined mixture into your greased baking dish, spreading it evenly with a spatula to ensure uniform cooking. This helps to create an even layer throughout, allowing all the flavors to meld together beautifully. The aroma will start to fill your kitchen as you prep for the next steps!
Step 5: Add the Cheesy Topping
Sprinkle the remaining mozzarella and Parmesan cheese generously over the top of your casserole mixture. This cheesy layer is key to achieving that classic gooey texture and a golden brown finish. Cover the dish tightly with aluminum foil to keep moisture in while it bakes.
Step 6: Bake the Casserole
Place the baking dish in your preheated oven and bake for 30 minutes covered. This initial baking allows the flavors to meld and the layers to come together. After 30 minutes, carefully remove the foil and return the casserole to the oven for an additional 10-15 minutes, watching closely for the cheese to become bubbly and start to turn golden brown.
Step 7: Let it Cool and Garnish
Once the Chicken Parmesan Casserole is perfectly baked, remove it from the oven and let it cool for about 5-10 minutes. This resting time helps set the layers and makes serving easier. Before serving, garnish with freshly chopped basil or parsley to add a bright touch and enhance the flavor.

How to Store and Freeze Chicken Parmesan Casserole
Fridge: Store leftover Chicken Parmesan Casserole in an airtight container for up to 3 days. Reheat at 350°F (175°C) until warmed through for best texture.
Freezer: For longer storage, freeze the casserole in a tightly sealed container for up to 3 months. To reheat, thaw overnight in the fridge before baking at 350°F (175°C) until bubbly.
Reheating: Avoid the microwave for reheating since it can make the casserole soggy. Instead, warm in the oven for a crispy top and even heating.
Covering: Always cover the casserole with foil when baking or reheating to prevent it from drying out—remove for the last few minutes for a golden crust.

Chicken Parmesan Casserole Recipe FAQs
What kind of chicken should I use for the casserole?
I recommend using shredded rotisserie chicken for convenience; it adds a lovely flavor and saves cooking time! If you prefer, you can also poach chicken breasts and shred them for a homemade touch.
How long can I store leftovers in the fridge?
Leftover Chicken Parmesan Casserole can be stored in an airtight container in the fridge for up to 3 days. To enjoy it at its best, reheat it in the oven at 350°F (175°C) until thoroughly warmed, which helps maintain its delicious texture.

How can I prevent the casserole from becoming soggy when reheating?
To avoid a soggy texture, I suggest reheating the casserole in the oven rather than the microwave. Preheat the oven to 350°F (175°C), cover the dish with foil for the first part of baking to keep moisture in, then uncover it for the last few minutes to crisp up the cheese topping.
Are there any dietary considerations for this recipe?
Yes! You can easily make adjustments for dietary needs. For a gluten-free option, substitute regular pasta with gluten-free pasta or zoodles. Additionally, if there are dairy allergies, consider using dairy-free cheese alternatives that melt well. Always check labels to ensure that any replacements fit your dietary restrictions.
What should I do if my casserole is dry?
If you find your Chicken Parmesan Casserole is a bit dry after baking, it might be helpful to add a little more marinara sauce on top or mix some into the pasta before layering. Ensuring the casserole is covered with foil during the initial baking can also retain moisture, so don’t skip that step!
