This Chicken Parmesan Casserole brings rotisserie chicken, marinara, Italian seasoning, Parmesan cheese, and mozzarella together, all sprinkled with a buttery Parmesan breadcrumb topping. This casserole is quick and easy enough for a weeknight meal and delicious enough for company.

This dish is a family favorite and always a welcome sight on the dinner table. With the use of rotisserie chicken, this is an easy, hearty dish on its own, or serve it with a simple garden salad, a bowl of minestrone, vegetable soup, French onion soup, or cheese garlic bread.
Ingredient Notes and Substitutions
See the complete list of ingredients on the recipe card below.
- Rigatoni pasta: You can substitute penne, rontini, or ziti
- Marinara: Use your favorite jarred marinara or homemade marinara
- Cooked chicken: Use any cooked chicken. I like to use rotisserie chicken because it is juicy and available at almost every grocery store or warehouse store.
- Cheese: Mozzarella cheese and Parmesan cheese. For optimal flavor, use freshly grated Parmesan Cheese. You can use any Italian cheese that melts well.
- Butter: Salted or unsalted works
- Breadcrumbs: Either panko or homemade
- Basil: Fresh basil for cutting ribbons
How to Make Chicken Parmesan Casserole
This is a summary version; for the complete list of ingredients and instructions, please refer to the recipe card below.
- Cook the pasta al dente according to the package directions, then drain well.
- Add the marinara, Italian seasoning, and cooked chicken to the cooked pasta and stir to combine.
- Layer half of the pasta mixture in a baking dish, then top with half of the mozzarella and half of the Parmesan.
- Add the remaining pasta mixture and the other half of the mozzarella and Parmesan.
- Cover the dish and bake for 10 minutes.
- Stir the breadcrumbs, Parmesan cheese, and Italian seasoning in melted butter, then sprinkle them over the casserole.
- Bake uncovered until the top is lightly browned and the cheese is melted.


Preparation Tips
- Grease or spray the casserole dish with nonstick baking spray to make cleanup easier.
- Cook the pasta al dente, which means the pasta is cooked a little firm to the bite. This helps the pasta not absorb all of the sauce.
- But basil ribbons are made by stacking the leaves on top of each other and gently rolling them into a cylinder cigar shape. Now, using a sharp knife, slice them extra thin.

Serving Suggestions
I like to serve this tasty casserole with no-knead bread or garlic knots. For a more nutritious option, serve with a copycat Olive Garden salad, tomato salad, or seven-layer salad.
