Ingredients for Chicken Parmesan Casserole

To create the perfect casserole, you’ll need the following ingredients:
Essential Ingredients
- 8 ounces penne pasta cooked al dente
- 24 ounce jar marinara sauce choose a brand you already love
- 1 tablespoon Italian seasoning to build a herby base
- ½ teaspoon salt for the chicken
- ¼ teaspoon pepper for the chicken
- ¼ teaspoon garlic powder for the chicken
- 1⅓ cups shredded mozzarella cheese divided between the layers and the topping
- 1 pound chicken breasts cut into bite-size cubes
- ⅓ cup grated parmesan cheese for the topping
- Fresh basil for topping
Optional Ingredients
- 1 cup baby spinach stirred into the sauce for extra greens
- ¼ teaspoon red pepper flakes for a gentle kick of heat
How to Prepare the Casserole
Follow these steps to get the base ready for the oven:
- Preheat and Cook the Pasta: Preheat the oven to 400°F (200°C) and grease a 9×13-inch baking dish. Bring a large pot of salted water to a boil and cook the penne for about 8 minutes, until just al dente, then drain well.
- Season the Chicken: In a medium bowl, toss the chicken cubes with ½ teaspoon salt, ¼ teaspoon pepper, and ¼ teaspoon garlic powder until evenly coated.
- Mix the Sauce: In a large bowl, stir the marinara sauce and 1 tablespoon Italian seasoning together, then add the drained penne and toss until every noodle is coated.
Assembly: Bringing It All Together
Once the pasta and chicken are prepped, it’s time to assemble your casserole!
- Layer the Casserole: Spread half of the sauced penne in the baking dish, scatter the seasoned chicken evenly over it, and sprinkle 1 cup of the mozzarella on top.
- Add the Remaining Pasta: Spoon the rest of the penne over the layers, then sprinkle with the remaining ⅓ cup mozzarella and the ⅓ cup parmesan.
- Bake Until Bubbly: Cover the dish loosely with foil and bake for 20 minutes, then uncover and bake for another 10 minutes, until the chicken reaches 165°F (74°C) and the cheese is golden.
- Garnish: Let the casserole rest for 5 minutes, then scatter torn fresh basil over the top before serving.

Variations and Customizations
One of the great things about this casserole is its versatility!
- Vegetable Additions: Stir sliced zucchini, bell peppers, or baby spinach into the sauce for a lighter, more colorful bake.
- Alternative Proteins: Swap the chicken for cubed turkey breast or cooked Italian sausage, adjusting the bake time until the center is fully cooked.
- Lighter Pasta: Use whole wheat penne or chickpea pasta for extra fiber and protein.
- Spicy Kick: Add red pepper flakes to the marinara or sprinkle crushed red pepper over the finished casserole.
Serving Suggestions
Pair this casserole with a simple green side like sautéed mushrooms with spinach to balance the rich, cheesy pasta.
For drinks, a crisp sparkling water with lemon or a light Chianti complements the tomato sauce and herbs beautifully.
