How to Make Chicken Parmesan Casserole Recipe
Step 1: Prep Your Oven and Dish
Start by preheating your oven to 375°F (190°C) so it’s ready to go when your casserole is assembled. Lightly grease a 9×13 inch baking dish to prevent sticking and make sure you can easily slide it out after baking.
Step 2: Layer the Chicken
Spread your shredded cooked chicken evenly across the base of the prepared baking dish. This ensures every bite gets that lovely, meaty foundation you’re craving.
Step 3: Add the Marinara Sauce
Pour the marinara sauce over the chicken and spread it out evenly. This adds moisture and that classic tomato flavor that ties the dish together beautifully.
Step 4: Cheese Time—First Round
Sprinkle half of the shredded mozzarella and half of the grated Parmesan evenly over the sauce. These cheeses create a gooey, flavorful layer that melts perfectly.
Step 5: Make the Topping Mixture
In a small bowl, combine the seasoned breadcrumbs with melted butter, Italian seasoning, salt, and pepper. Mix well until the breadcrumbs are evenly coated; this will give your casserole that irresistible golden crunch.
Step 6: Add the Breadcrumb Layer
Sprinkle the breadcrumb mixture over the cheese layer, covering it completely. This adds texture and a wonderful contrast to the soft cheesy layers underneath.
Step 7: Finish with Cheese
Top everything off with the remaining mozzarella and Parmesan cheeses. This extra layer ensures the casserole is cheesy through and through, with a beautiful browned top.
Step 8: Bake Until Bubbly
Place the casserole in your preheated oven and bake for 25-30 minutes. You’ll know it’s ready when the cheese is bubbly and golden brown, and the topping is crisp and inviting.
Step 9: Garnish and Cool
If you like, sprinkle fresh chopped basil on top before serving for a pop of color and fresh flavor. Let the casserole rest for a few minutes so it sets slightly, making it easier to serve and enjoy.
How to Serve Chicken Parmesan Casserole Recipe

Garnishes
Fresh basil isn’t just for looks; it adds a bright herbal note that cuts through the richness of the cheese and sauce perfectly. A light drizzle of extra virgin olive oil or a sprinkle of crushed red pepper flakes can also add visual appeal and flavor twists.
Side Dishes
This casserole pairs wonderfully with simple sides like a crisp green salad tossed in lemon vinaigrette or steamed vegetables such as broccoli or asparagus. Garlic bread or warm crusty rolls are excellent for scooping up any leftover sauce and cheese.
Creative Ways to Present
For a fun spin, serve individual portions in ramekins or mini cast iron skillets. You can also layer this casserole over cooked pasta or spaghetti squash to amplify the meal’s heartiness and bring a fresh twist to presentation.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover leftovers tightly with plastic wrap or transfer to an airtight container. Stored properly in the fridge, this Chicken Parmesan Casserole Recipe stays delicious for up to 3-4 days, making it ideal for quick lunches or dinners later in the week.
Freezing
You can freeze this casserole either before or after baking. For best results, assemble it in a freezer-safe container and cover it well. It will keep for up to 3 months. When ready, thaw overnight in the fridge before baking or reheating.
Reheating
Reheat leftovers in the oven at 350°F (175°C) for about 15-20 minutes until heated through and bubbly. Using the oven keeps the cheesy topping crisp, unlike the microwave which might make it soggy.
FAQs
Can I use fresh chicken instead of cooked chicken?
Absolutely! Just cook and shred the chicken first before using it in the casserole. This ensures it’s fully cooked and tender when baked.
What if I don’t have Italian seasoning?
Mix dried oregano, basil, and thyme to make your own Italian seasoning blend. A pinch of garlic powder also adds great flavor!
Is this recipe gluten-free?
You can make it gluten-free by using gluten-free breadcrumbs. Everything else in the recipe is naturally gluten-free.
Can I add vegetables to the casserole?
Definitely! Spinach, mushrooms, or bell peppers work great layered in or mixed with the chicken for added nutrition and flavor.
How can I make this casserole spicier?
Try adding crushed red pepper flakes to the breadcrumb mix or stir some spicy marinara sauce into the chicken layer for a gentle kick.
