Chicken Parmesan Casserole Ingredients
- 3 cups cooked chicken, shredded or cut into small pieces
- 12 ounces penne or ziti pasta
- 3 cups marinara sauce
- 1 ½ cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 1 cup shredded Italian cheese blend
- 2 tablespoons olive oil

How to Make Chicken Parmesan Casserole
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil. Add the pasta and cook until just al dente. Drain well and set aside. Do not overcook the pasta because it will continue cooking in the oven.
Step 2: Prepare the Chicken
Place the cooked chicken in a large bowl and cut or shred it into small pieces. Add the Italian seasoning, garlic powder, onion powder, salt, black pepper, and olive oil. Stir until the chicken is evenly coated.
Step 3: Combine the Ingredients
Add the cooked pasta and about two cups of marinara sauce to the chicken. Stir gently until everything is well mixed. Add half of the mozzarella, Italian cheese blend, and Parmesan, then mix again.
Step 4: Assemble the Casserole
Preheat the oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and spread a little marinara sauce over the bottom. Add the chicken and pasta mixture and spread it into an even layer. Pour the remaining sauce over the top.
Step 5: Add the Cheese and Bake
Sprinkle the remaining mozzarella, Italian cheese blend, Parmesan, and breadcrumbs evenly over the casserole. Cover loosely with foil and bake for 20 minutes. Remove the foil and bake for another 10–15 minutes, until the cheese is melted, bubbly, and lightly golden.
Step 6: Rest and Serve
Take the casserole out of the oven and let it rest for 5–10 minutes. This helps the cheese and sauce settle so it is easier to serve. Sprinkle with fresh parsley, then scoop and serve while warm.
