Chicken Parmesan is traditionally made by coating chicken, frying it, spooning over sauce, and finishing it with cheese. This casserole keeps the familiar flavors but places everything in one baking dish, making it easier to prepare on a busy evening.
The recipe is especially useful when you have leftover chicken or a store-bought rotisserie chicken ready to shred. The chicken absorbs the marinara as it bakes, while the pasta gives the dish enough substance to serve as a complete dinner.
- Family-friendly: Mild tomato sauce, pasta, and melted cheese appeal to both children and adults.
- Simple preparation: The ingredients are mixed together rather than layered or individually breaded.
- Make-ahead friendly: You can assemble the casserole while the oven heats and have dinner on the table in under an hour.
- Comforting texture: The center is saucy and cheesy, while the breadcrumb topping adds a pleasant crunch.

Ingredients You’ll Need
Start with 12 ounces of penne or ziti. These short tube-shaped pastas hold onto marinara and are easy to scoop from the finished casserole, though either shape works well.
You will need 3 cups of cooked diced or shredded chicken. Rotisserie chicken is convenient and flavorful, but 1 1/2 pounds of boneless, skinless chicken breasts can also be cooked and chopped for this recipe.
Use 24 ounces of marinara sauce for a rich tomato base. If you prefer a looser, more tomato-forward casserole, a 14–15-ounce can of drained diced tomatoes is a common optional addition, but the sauce quantity remains the same.
The seasoning is intentionally straightforward: Italian seasoning, garlic powder, salt, and black pepper. Two cups of shredded mozzarella provide the melted cheese pull, while 1/2 cup of grated Parmesan adds the salty, nutty flavor associated with chicken Parmesan.
For the topping, choose Italian-seasoned breadcrumbs or panko. Regular breadcrumbs also work, and mixing them with 2 tablespoons of olive oil or melted butter helps them brown and crisp in the oven.
How to Make It Step-by-Step
Step 1: Heat the oven to 375°F and lightly grease a 9-by-13-inch baking dish. Greasing the dish helps the saucy pasta lift out more easily and makes cleanup less troublesome.
Step 2: Bring a large pot of salted water to a boil and cook the penne or ziti until it is just shy of al dente, usually 1–2 minutes less than the package directions. Drain thoroughly, since excess water can thin the marinara and make the casserole less cohesive.
Step 3: Add the drained pasta to a large mixing bowl with the cooked chicken, marinara sauce, Italian seasoning, garlic powder, 1/2 teaspoon salt, black pepper, 1 cup of mozzarella, and the Parmesan. Toss gently until the pasta and chicken are evenly coated without breaking the pasta.
Step 4: Transfer the mixture to the greased baking dish and spread it into an even layer. An even surface helps the cheese melt consistently and ensures that each serving contains pasta, chicken, and sauce.
Step 5: Sprinkle the remaining 1 cup of mozzarella over the top. Mix the breadcrumbs with the olive oil or melted butter in a small bowl, then scatter the coated crumbs over the mozzarella for a golden, crunchy finish.
Step 6: Bake the casserole uncovered for 20–25 minutes, until the sauce is bubbling around the edges and the cheese is fully melted. For more browning, broil for 1–2 minutes at the end, staying close to the oven because the topping can darken quickly.
Step 7: Remove the baking dish from the oven and let it rest for 5 minutes before serving. Finish with chopped fresh basil or parsley if desired, then spoon the casserole onto plates while it is warm and saucy.
Chef Tips for the Best Casserole
The most important detail is to slightly undercook the pasta. It continues cooking in the marinara while the casserole bakes, so fully cooked pasta may become soft or mushy by the time the cheese is bubbling.
Drain the pasta well, but do not rinse it. The small amount of surface starch helps the sauce cling to the pasta and gives the finished casserole a more unified texture.
If you use freshly cooked chicken, let it cool briefly before combining it with the cheese. Very hot chicken can start melting the mozzarella in the mixing bowl, making it harder to distribute evenly.
Rotisserie chicken is an excellent shortcut because its seasoning adds extra flavor without requiring another cooking step. Remove the skin and bones, then dice or shred enough chicken to measure 3 cups.
For the crispiest topping, select panko breadcrumbs and mix them thoroughly with the oil or melted butter. Provolone or an Italian cheese blend can replace part of the mozzarella if you want a slightly different cheese flavor.
For another chicken dinner with bold seasoning, keep our all-purpose Buffalo marinade in mind for a future meal. It is a separate preparation, but it can inspire a spicy direction when you are planning your weekly menu.
Serving Suggestions
This casserole is hearty enough to serve on its own, especially when each portion includes plenty of chicken and bubbling sauce. A simple green salad adds freshness without competing with the rich cheese.
Steamed broccoli, roasted zucchini, or green beans also make good side dishes. For a classic Italian-American dinner, add warm garlic bread so every drop of marinara can be enjoyed.
Letting the casserole rest for 5 minutes is worth the short wait. The sauce settles slightly, the cheese remains pleasantly stretchy, and the portions are easier to serve without spreading across the plate.

Storage and Reheating
Cool leftover casserole, cover the baking dish, and refrigerate it promptly. Stored leftovers are best reheated until hot throughout, either in the microwave for individual portions or in a covered oven-safe dish for a larger amount.
If reheating in the oven, use moderate heat and cover the dish so the pasta does not dry out before the center is warm. Remove the cover near the end if you want to refresh the crispness of the breadcrumb topping.
The casserole can also be assembled ahead for a convenient dinner. Keep it chilled until baking, and make sure the center is hot and bubbling before serving.
Easy Variations
Use either diced or shredded chicken depending on the texture you prefer. Diced chicken creates distinct bites throughout the casserole, while shredded chicken spreads more evenly into the sauce.
For a more tomato-forward version, stir in a drained 14–15-ounce can of diced tomatoes. The result will be a little looser and more textured while still retaining the marinara flavor.
Regular breadcrumbs, seasoned breadcrumbs, and panko are all suitable. Panko gives the most noticeable crunch, while Italian-seasoned crumbs add herbs directly to the topping.
Part of the mozzarella may be replaced with provolone or an Italian cheese blend. Keep the total cheese quantities the same so the casserole retains its creamy, bubbling topping.
After dinner, a fruit-based treat such as our pineapple banana dessert can provide a bright finish. If you prefer another baked one-dish dinner for your rotation, our Big Mac casserole offers a completely different take on comfort food.
