Equipment

1 Large Pot
1 Skillet
1 Large mixing bowl
1 9x13 inch baking dish

Ingredients

Main Ingredients

12 oz pasta such as penne, rigatoni, or ziti
3 cups cooked chicken shredded or diced, rotisserie chicken works well
24 oz marinara sauce
14 oz crushed tomatoes
2 tbsp olive oil
1 small onion finely chopped
3 cloves garlic minced
1 tsp Italian seasoning
1 tsp salt or to taste
1 2 black pepper to taste
2 cups mozzarella cheese shredded, divided
1 cup Parmesan cheese freshly grated, divided

Topping

1 cup bread crumbs
2 tbsp butter melted, or use olive oil
2 tbsp fresh parsley or basil optional, for finishing

Instructions

Bring a large pot of salted water to a boil and cook the pasta until just al dente. Drain it well so the casserole stays saucy, not watery.
Warm olive oil in a skillet, then cook the onion until soft. Add the garlic and cook briefly, then stir in the marinara sauce, crushed tomatoes, Italian seasoning, salt, and pepper. Let the sauce simmer so the flavors blend.
In a large bowl, combine the cooked pasta, chicken, and sauce. Stir in part of the mozzarella and Parmesan so the filling gets cheesy all the way through.
Spoon the mixture into a greased baking dish and spread it into an even layer. Sprinkle the remaining mozzarella and Parmesan over the top.
Mix the breadcrumbs with melted butter or a little olive oil, then scatter them over the cheese. This gives the casserole a lovely golden finish.
Bake until the sauce is bubbling and the top is golden brown. Let the casserole rest for a few minutes before serving so it sets up nicely.

Notes

Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze portions in freezer-safe containers for up to 2 months. To reheat, warm individual servings in the microwave with a splash of water or sauce to help keep the pasta moist. You can also reheat the full casserole in the oven at 350°F until warmed through.

Step-by-Step Instructions to Make Chicken Parmesan Pasta Casserole

Step 1: Cook the pasta

Bring a large pot of salted water to a boil and cook the pasta until just al dente. Drain it well so the casserole stays saucy, not watery.

Step 2: Build the sauce

Warm olive oil in a skillet, then cook the onion until soft. Add the garlic and cook briefly, then stir in the marinara sauce, crushed tomatoes, Italian seasoning, salt, and pepper. Let the sauce simmer so the flavors blend.

Step 3: Mix everything together

In a large bowl, combine the cooked pasta, chicken, and sauce. Stir in part of the mozzarella and Parmesan so the filling gets cheesy all the way through.

Step 4: Assemble the casserole

Spoon the mixture into a greased baking dish and spread it into an even layer. Sprinkle the remaining mozzarella and Parmesan over the top.

Step 5: Add the breadcrumb topping

Mix the breadcrumbs with melted butter or a little olive oil, then scatter them over the cheese. This gives the casserole a lovely golden finish.

Step 6: Bake until bubbly

Bake until the sauce is bubbling and the top is golden brown. Let the casserole rest for a few minutes before serving so it sets up nicely.

Tips for Success

Do not overcook the pasta, since it will continue baking in the oven.
Use well-drained chicken so the casserole does not become soggy.
Let the baked dish rest before slicing, this helps the layers hold together.
If the top browns too quickly, cover it loosely with foil during the last part of baking.

FAQs

Can I make this casserole ahead of time?

Yes, you can assemble it a day in advance, cover it, and refrigerate it until you are ready to bake. Add a few extra minutes in the oven if it goes in cold.

What pasta works best?

Short, sturdy shapes like penne, rigatoni, or ziti work best because they hold the sauce and bake evenly.

Can I use uncooked chicken?

For the best texture and food safety, cook the chicken first before mixing it into the casserole. Rotisserie chicken is a very easy option.

How do I keep the topping crispy?

Mix the breadcrumbs with butter or oil right before baking, and bake uncovered so the top can turn golden and crisp.
