Ingredients You’ll Need

1 pound dry rotini pasta: Great for holding onto the sauce, rotini provides the perfect bite. You can substitute any short pasta like penne or fusilli.
3 cups chopped cooked chicken: Using leftover rotisserie chicken is a time-saver, but you can also pan-cook or bake your chicken for fresh flavor.
24 ounces marinara sauce: A quick sauce covers the pasta, giving it depth. Choose your favorite store-bought jar or make your own for a personal touch.
1 teaspoon Italian seasoning: This blend boosts the flavor; if you’re out, mix equal parts basil, oregano, and thyme.
1½ cups shredded mozzarella cheese: Melty mozzarella adds creamy richness. You can mix it with provolone or cheddar for unique flavors.
½ cup breadcrumbs: For a crunchy topping, use unseasoned or Italian-flavored breadcrumbs. Panko breadcrumbs can add an extra crisp texture!
2 tablespoons unsalted butter (¼ stick, melted): Helps the breadcrumbs brown nicely. If you’re looking for a dairy-free option, use olive oil.
2 tablespoons grated parmesan cheese (plus more for topping): Adds a salty bite; fresh grated Parmesan can elevate the flavor further.
Chopped fresh parsley (optional, for topping): This gives a pop of color and freshness.

How to Make Chicken Parmesan Casserole

Preheat the Oven: Preheat your oven to 400°F. Spray a 4-quart casserole dish with nonstick spray and set it aside to prepare for the delicious layers to come.
Cook the Pasta: Cook 1 pound of dry rotini pasta according to package directions, but stop one minute short of al dente. Drain the pasta and let it cool slightly—this prevents overcooking in the oven.
Mix Ingredients: In a large bowl, combine the cooked pasta, 3 cups chopped cooked chicken, 24 ounces marinara sauce, and 1 teaspoon of Italian seasoning. Stir everything together until well-coated and mixed.
Transfer to Casserole Dish: Pour the mixture into the prepared casserole dish, spreading it evenly to ensure every bite gets a bit of sauce.
Top with Cheese: Sprinkle 1½ cups shredded mozzarella cheese generously over the top, covering the pasta and chicken.
Prepare Breadcrumb Mixture: In a small bowl, combine ½ cup breadcrumbs with 2 tablespoons melted unsalted butter. Mix until the crumbs are well-coated and clump together slightly.
Sprinkle Breadcrumbs: Evenly distribute the breadcrumb mixture over the cheese layer, then finish off by adding 2 tablespoons grated Parmesan cheese for an extra cheesy crust.
Bake: Place the casserole in the oven and bake for 18-20 minutes, or until the breadcrumbs are golden brown and the sauce is bubbling around the edges. Once it looks perfect, sprinkle chopped fresh parsley and additional grated Parmesan on top before serving.

Storing & Reheating

To store leftover Chicken Parmesan Casserole, let it cool completely before placing it in an airtight container in the refrigerator for up to 3–4 days. If you prefer a longer storage option, freeze your casserole in a freezer-safe dish covered tightly with plastic wrap and foil for up to 3 months. When ready to eat, thaw overnight in the refrigerator and reheat in a 350°F oven for 20–25 minutes, until heated through. You might notice a slight change in texture, so adding a splash of marinara sauce can help refresh it!

Chef’s Helpful Tips

Watch your pasta: Ensure you don’t cook it too long, or it will turn mushy in the oven.
Chicken temperature: If your chicken is cold from the fridge, let it sit out for 15 minutes, or microwave briefly to reach room temperature for even cooking.
Timing: Keep an eye on your casserole in the last few minutes of baking—you want that golden brown, not burnt.
Flavor boost: For a little heat, add some crushed red pepper flakes to the marinara sauce, or mix in some sautéed garlic before combining with the pasta.
Make-ahead option: Assemble the casserole ahead of time, cover, and pop it in the fridge until you’re ready to bake. Just add a few minutes to the cooking time if it’s chilled.

This Chicken Parmesan Casserole offers the ultimate comfort with ease and flavor. With layers of tender pasta, juicy chicken, and bubbling cheese, it becomes a family favorite that you can whip up in no time. Don’t hesitate to enhance the recipe to fit your tastes; maybe add some veggies or switch up the cheeses. Trust me, you’ll want to make this again and again!

Recipe FAQs

Can I use frozen chicken?

Absolutely! Just make sure to fully cook and shred the chicken before adding it to the casserole. It’s a great way to save time!

Can I prepare this casserole ahead of time?

Yes! You can assemble the casserole a day in advance. Cover it tightly with plastic wrap and store it in the refrigerator. When ready to bake, remove it from the fridge and follow the baking instructions, adding extra cooking time if it’s cold.

What if I want to make this pasta gluten-free?

For a gluten-free option, simply substitute the dry rotini pasta with gluten-free pasta. You might also want to check your breadcrumbs for gluten if that’s a concern.

Can I add vegetables to this Chicken Parmesan Casserole?

Of course! Spinach, bell peppers, or even zucchini would work nicely. Just sauté them beforehand to reduce moisture and make them tender before adding to the casserole.
