Dump and Bake Chicken Parmesan Casserole is the kind of dinner that makes a busy night feel a whole lot easier. It has everything people love about classic chicken parmesan, including tender chicken, rich marinara, plenty of melted cheese, and comforting pasta, but without the extra breading, frying, or standing over the stove.

This is the sort of meal that works when you want something warm, filling, and family friendly without turning dinner into a big project. Everything comes together in one baking dish, which means less prep, fewer dishes, and a cozy casserole that comes out bubbly, cheesy, and ready to serve.

Why You’ll Love This Dump and Bake Chicken Parmesan Casserole

This casserole earns a regular spot in the dinner rotation because it keeps things simple while still tasting like a proper comfort meal. You get the saucy, cheesy flavor of chicken parmesan in a format that is easier to prep and easier to serve. It is hearty enough for a full dinner, flexible enough for weeknights, and great for feeding hungry people without much fuss.

It is also a smart make-ahead option. You can assemble it earlier in the day, refrigerate it, and bake it when you are ready. Leftovers reheat well, so it is just as useful for meal prep as it is for a casual family dinner.

Do I Need to Cook the Pasta First?

One of the best things about Dump and Bake Chicken Parmesan Casserole is that the pasta cooks right in the baking dish. That means you do not need to boil it ahead of time, and you do not need another pot on the stove. As the casserole bakes, the pasta absorbs flavor from the marinara sauce and broth, which makes the finished dish extra tasty.

The key is using a pasta shape that bakes well and giving it enough liquid to soften properly. Penne, rotini, or ziti all work nicely here because they hold their shape and catch the sauce in every bite.

Ingredients for the Dump and Bake Chicken Parmesan Casserole

This ingredient list keeps the recipe easy, but every item pulls its weight. The pasta turns this into a complete casserole, the chicken makes it filling, and the marinara plus cheeses create that familiar chicken parmesan flavor. A little seasoning ties everything together so the final dish tastes rich and balanced straight from the oven.

How To Make the Dump and Bake Chicken Parmesan Casserole

A few simple steps are all it takes to get this casserole into the oven. The beauty of the method is that you do most of the work in one dish, then let the oven take care of the rest.

Step 1: Prep the Baking Dish

Preheat your oven to 425°F. Lightly grease a 9×13-inch baking dish so the pasta and sauce do not stick around the edges.

Step 2: Combine the Base Ingredients

Add the uncooked penne, diced chicken, marinara sauce, chicken broth, olive oil, Italian seasoning, garlic powder, salt, and black pepper directly to the baking dish. Stir well so the pasta is evenly coated and the chicken is distributed throughout.

Step 3: Cover and Bake

Cover the dish tightly with foil and bake for 35 minutes. This covered baking time traps the moisture, which helps the pasta soften and keeps the chicken tender.

Step 4: Add the Cheese

Remove the foil carefully and give the casserole a gentle stir. Sprinkle the mozzarella and Parmesan evenly over the top so every scoop gets a cheesy finish.

Step 5: Bake Until Bubbly

Return the dish to the oven uncovered and bake for another 10 to 15 minutes, or until the cheese is melted and the casserole is bubbling around the edges.

Step 6: Rest and Finish

Let the casserole rest for about 5 minutes before serving. This gives the sauce a chance to settle slightly and makes it easier to scoop. Finish with chopped parsley for a fresh pop of color.

Serving and Storing Dump and Bake Chicken Parmesan Casserole

This casserole feeds about 6 people generously, which makes it a solid option for family dinner or casual entertaining. Serve it hot straight from the baking dish while the cheese is still melty and the sauce is bubbling.

Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm larger portions in the oven covered with foil. If you want to freeze it, let the casserole cool completely first, then freeze in portions for up to 2 months. Thaw overnight in the refrigerator before reheating.
