Step‑by‑Step Instructions for Chicken Parmesan Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This will ensure it reaches the perfect temperature while you prepare the Chicken Parmesan Casserole, leading to a beautifully cooked dish. As the oven warms up, gather your ingredients, and get ready for a delightful cooking experience.
Step 2: Combine the Ingredients
In a large mixing bowl, combine the 2 cups of cooked shredded chicken, 1 cup of marinara sauce, and 1 cup of cooked pasta. Add in ½ cup of shredded mozzarella cheese, ½ cup of grated Parmesan cheese, 1 teaspoon of Italian seasoning, ½ teaspoon of garlic powder, and season with salt and pepper to taste. Stir everything together until well blended, creating a comforting and hearty mixture.
Step 3: Transfer to Baking Dish
Carefully pour the chicken mixture into a greased 9x13-inch baking dish. Use a spatula to spread the mixture evenly across the dish, ensuring that every bite of the Chicken Parmesan Casserole is filled with those delicious flavors. Make sure the surface is level, so it cooks evenly in the oven.
Step 4: Add Breadcrumb Topping
Sprinkle ½ cup of breadcrumbs over the top of the casserole, providing a crunchy texture that contrasts beautifully with the creamy filling. If you desire a golden crust, drizzle a bit of olive oil (about 2 tablespoons) over the breadcrumbs, enhancing both flavor and color as it bakes.
Step 5: Bake to Perfection
Place the baking dish in your preheated oven and bake for 25-30 minutes. Keep an eye on your Chicken Parmesan Casserole; it’s ready when the cheese is bubbly and the breadcrumbs have turned a golden brown. This is the moment you’ll want to savor, as the inviting aroma fills your kitchen.
Step 6: Cool and Garnish
Once baked, remove the casserole from the oven and let it cool for a few minutes. This cooling phase allows the casserole to set, making it easier to serve. Just before your family digs in, sprinkle some fresh parsley on top to add a pop of color and freshness to your Chicken Parmesan Casserole.

Chicken Parmesan Casserole Recipe FAQs
How do I choose the right chicken for this casserole?
Absolutely! For the best flavor and texture, use cooked shredded chicken, which can be made from rotisserie chicken or leftovers. If using fresh chicken breasts, simply poach them in water or broth until cooked through, then shred. Aim for chicken that is soft and moist, as this will create a sumptuous base for your casserole.
How should I store leftover Chicken Parmesan Casserole?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Make sure to let the casserole cool completely before sealing it. When ready to enjoy, reheat in the oven at 350°F (175°C) for about 15-20 minutes, or until warmed through, ensuring it reaches an internal temperature of 165°F (74°C).
Can I freeze Chicken Parmesan Casserole?
Yes, you can freeze this casserole for up to 3 months! To do this, assemble the dish as instructed but do not bake it. Cover tightly with plastic wrap and then aluminum foil to prevent freezer burn.

What can I do if my casserole doesn't seem to cook properly?
Very! If your casserole isn’t cooking evenly, check whether your oven is calibrated correctly, as baking times can vary. To ensure the cheese melts and the topping is golden brown, consider covering the dish with foil for the first 15 minutes of baking to help it cook through, then remove the foil to allow the top to crisp up.
Is this recipe suitable for those with dietary restrictions?
Definitely! You can customize your Chicken Parmesan Casserole to fit various dietary needs. For gluten-free options, substitute regular pasta and breadcrumbs with gluten-free versions. For those on a low-carb diet, consider using zucchini noodles or spaghetti squash as a pasta alternative. Always be mindful of any allergies your guests may have, such as cheese or specific herbs.
