If you want a cozy, delicious meal without a lot of work, this chicken parmesan casserole is sure to become one of your go-tos.
Key Ingredients & Substitutions
Cooked Pasta: Rigatoni or penne work great due to their tube shape, which holds sauce well. If you don’t have these, elbow macaroni or rotini are good alternatives. Just make sure not to overcook the pasta since it bakes later.
Chicken: Using pre-cooked chicken keeps things quick. Rotisserie chicken is a favorite of mine for its flavor and ease. You can also swap with cooked turkey or even a plant-based chicken alternative for a vegetarian twist.
Marinara Sauce: A good quality marinara sauce is important for flavor. If you like spicy food, try adding some red pepper flakes or use a spicy arrabbiata sauce. Homemade or store-bought both work well here.
Cheeses: Mozzarella gives that melty, stretchy texture, while Parmesan adds sharpness. Feel free to mix in provolone or fontina for a different cheese flavor. For a dairy-free option, look for vegan cheese substitutes that melt well.
Italian Seasoning & Garlic: These bring classic flavor with little effort. If you don’t have Italian seasoning, a mix of dried oregano, basil, and thyme works fine. Fresh garlic is best, but garlic powder can be used in a pinch.
How Do You Make Sure the Casserole is Perfectly Bubbly and Cheese-Melty?
Getting the right bake on your casserole is all about timing and layering.
- Preheat your oven well so it heats evenly.
- Mix pasta and chicken with sauce thoroughly so every bite is flavorful.
- Spread the mixture evenly in the dish for consistent cooking.
- Sprinkle cheese in an even layer on top—don’t skimp! This helps create that gooey cheese crust.
- Bake at 375°F for 25-30 minutes until you see bubbling sauce around the edges and golden-brown cheese on top.
- Let it sit 5 minutes after baking. This rest time helps the cheese set a bit and the dish cools just enough to enjoy without burning your mouth.
By following these steps, you’ll get a melty, bubbly casserole that’s comforting and delicious every time.

Step-by-Step Instructions:
1. Get Your Oven and Dish Ready:
Preheat your oven to 375°F (190°C). Lightly spray or brush your 9×13-inch baking dish with cooking spray or olive oil to stop the casserole from sticking.
2. Mix Ingredients Together:
In a big bowl, add the cooked pasta, cooked chicken, marinara sauce, Italian seasoning, and minced garlic. Season with salt and pepper to taste. Stir everything until the sauce coats all the pasta and chicken evenly.
3. Transfer and Layer:
Pour your pasta and chicken mix into the greased baking dish. Spread it out so it’s nice and even. Then sprinkle the mozzarella and Parmesan cheese all over the top.
4. Bake Until Bubbly:
Put the casserole in the oven and bake for 25-30 minutes. You’ll know it’s ready when you see the sauce is bubbling around the edges and the cheese on top is melted and lightly golden.
5. Rest, Garnish, and Serve:
Take the casserole out and let it rest for about 5 minutes. This helps it settle and cool enough to serve safely. Sprinkle the fresh parsley on top for a nice color and fresh flavor. Serve warm and enjoy your delicious chicken parmesan casserole!
Can I Use Frozen Chicken in This Recipe?
Yes, but be sure to fully thaw the chicken before using it. Thaw frozen chicken in the fridge overnight or use the cold water method for quicker thawing. Pat the chicken dry before mixing it into the casserole to avoid extra moisture.
Can I Prepare This Casserole Ahead of Time?
Absolutely! You can assemble the casserole completely and cover it tightly with foil, then refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if baking from cold.
How Should I Store Leftovers?
Store leftovers in an airtight container in the fridge for up to 3 days. To reheat, warm gently in the oven or microwave until heated through, stirring occasionally to keep the cheese melted evenly.
Can I Use a Different Type of Pasta?
Yes! Any short pasta like penne, rigatoni, rotini, or elbow macaroni works well. Just make sure to cook it al dente since it will bake again and might get mushy if overcooked.
