Method
Preparation
- Set your oven to 375°F (190°C).
- In a large 9x13-inch baking dish, toss together the cooked pasta, diced chicken, marinara sauce, Italian seasoning, and a generous pinch of salt and black pepper.
- Stir everything gently until every piece is coated in sauce.
- Sprinkle the shredded mozzarella and grated Parmesan evenly over the top.
Baking
- Place the dish on the center rack and bake for 25 to 30 minutes, until the sauce is bubbling around the edges and the cheese is melted and golden.
- Let the casserole rest for 5 minutes, then garnish with fresh basil if you like, and serve warm.

Notes
Use pasta that is slightly undercooked (al dente) since it will continue to cook in the oven; mushy pasta ruins the texture.
Any short pasta shape, such as penne, rigatoni, or fusilli, works well. Gluten-free pasta can be substituted, but be careful not to overcook it before baking.
Swap the cooked chicken with leftover turkey, rotisserie chicken, or even cooked Italian sausage for a different flavor.
If you prefer a crispier topping, sprinkle an extra 1/4 cup of panko breadcrumbs mixed with a little olive oil over the cheese before baking.
Assemble the casserole up to 24 hours in advance, cover and refrigerate. Add 5 to 10 minutes to the baking time when baking cold.
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat individual portions in the microwave or in a 350°F oven until hot.
Let the casserole rest for 5 to 10 minutes after baking so the layers set and the flavors meld.
