Ingredients for Chicken Parmesan Casserole
Over the years I have tested this with different pasta shapes and cheeses, and I have landed on a combination that works beautifully every single time. If you have ever made my Chicken Mozzarella Pasta, you already know how well these flavors come together. Keeping things simple with quality ingredients makes all the difference in this chicken Parmesan casserole.
- 4 cups cooked chicken, shredded
- 2 cups marinara sauce – I recommend a good jarred marinara with no added sugar for the cleanest flavor
- 1 cup grated Parmesan cheese, divided
- 2 cups shredded mozzarella cheese, divided – In my experience, whole-milk mozzarella melts much better than part-skim
- 2 cups cooked pasta such as penne or rotini – My preference is penne because it holds the sauce inside each piece
- 1 tablespoon olive oil
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- Salt and pepper to taste
- Fresh basil or parsley for garnish, optional – I usually add a handful of fresh basil right before serving for a bright finish
Step-by-Step Instructions
In my experience, the key to a great chicken Parmesan casserole is layering the flavors before anything goes into the oven. Taking a few extra minutes at the stovetop makes a real difference in the final dish. I use the same approach in my Baked Tuscan Chicken Casserole and it always pays off.
Step 1: Preheat your oven to 375 degrees F and lightly grease a 9×13-inch baking dish with cooking spray or a little olive oil.
Step 2: Heat olive oil in a large skillet over medium heat. Add the shredded chicken, garlic powder, Italian seasoning, salt, and pepper. Stir everything together and cook for about 5 minutes until the chicken is warmed through and fragrant.
Step 3: In a large mixing bowl, combine the cooked pasta, marinara sauce, half the Parmesan, and half the mozzarella. Stir until well combined. Pro tip: your pasta should look slightly undercooked at this stage since it will continue cooking in the oven. Overcooked pasta will turn mushy by the time the casserole is done.
Step 4: Add the seasoned chicken to the pasta mixture and stir until evenly distributed.
Step 5: Pour the mixture into the prepared baking dish and spread it out in an even layer.
Step 6: Top with the remaining mozzarella and Parmesan cheese.
Step 7: Cover tightly with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden brown on top. Let it rest for about 5 minutes before serving so everything holds together when you scoop it. Garnish with fresh basil or parsley if desired.
What to Serve with Chicken Parmesan Casserole
This casserole is hearty on its own, but the right sides pull the meal together with lighter flavors and fresh textures. Here are some of the best sides for chicken Parmesan casserole that my family loves most.
Garlic Bread: There is nothing better than a thick slice of warm garlic bread for scooping up that extra marinara sauce. If you want a quick homemade option, my Easy Garlic Bread with Sliced Bread comes together in minutes.
Simple Green Salad: A crisp romaine or mixed greens salad with a light Italian dressing balances the richness of the dish and adds a refreshing element to the plate.
Steamed Broccoli: Broccoli pairs naturally with Italian flavors and adds a nutritious, vibrant green side that both kids and adults appreciate. For a more flavorful version, try my Garlic Butter Chicken and Broccoli as a companion recipe on your weekly menu.

Roasted Zucchini: Thinly sliced zucchini roasted with olive oil and herbs soaks up the sauce and adds a tender, slightly caramelized flavor that complements the casserole well. My Easy Chicken Zucchini Bake uses the same pairing and it is always a hit.
Caesar Salad: A classic Caesar with crunchy croutons and shaved Parmesan echoes the cheesy notes in the casserole while adding a tangy, creamy contrast.

How to Store and Reheat Chicken Parmesan Casserole
Store leftovers in an airtight container in the refrigerator for up to 4 days. This casserole holds up really well, making it a solid choice for meal prep or next-day lunches.
To reheat, I recommend covering the dish with foil and warming it in a 350 degree oven for about 15 minutes, or until heated through. This keeps the pasta from drying out and gets the cheese perfectly melty again. For single servings, the microwave works fine with a splash of water added to keep things moist.
Pro tip: this chicken Parmesan casserole actually tastes even better the next day once the flavors have had time to settle. Consider assembling it the night before, refrigerating it unbaked, and then popping it in the oven when you get home. Add about 10 extra minutes to the covered bake time since it will go in cold.
FAQs
Can I use rotisserie chicken for this recipe?
Absolutely. Rotisserie chicken is one of the best shortcuts for this casserole. It is already seasoned and tender, which saves you prep time without losing any flavor.
Can I make chicken Parmesan casserole ahead of time?
Yes, you can assemble the casserole up to 24 hours in advance, cover it tightly, and refrigerate it. When you are ready to bake, add about 10 extra minutes to the covered bake time since it will be going in cold from the fridge.
Can I freeze this casserole?
You can freeze it before or after baking. Wrap it tightly in plastic wrap and foil and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating in the oven for best results.
