Essential Ingredients & Smart Substitutions
Here are the key ingredients that make this casserole so flavorful and foolproof:

- Boneless, Skinless Chicken Breasts: 1.5 pounds cut into bite-sized 1-inch cubes so they cook evenly with the pasta. You can also use boneless chicken thighs.
- Uncooked Penne Pasta: 8 oz (about 2 cups) dry penne or rotini pasta. The pasta absorbs the savory marinara and broth as it bakes.
- Marinara Sauce: 1 jar (24 oz) of your favorite quality marinara or pasta sauce.
- Chicken Broth: 2 cups low-sodium chicken broth (or water), providing the essential liquid for the pasta to bake to perfect al dente tenderness.
- Shredded Mozzarella Cheese: 2 cups shredded whole-milk or part-skim mozzarella for that signature stretchy, cheesy layer.
- Grated Parmesan Cheese: 1/2 cup finely grated Parmesan for rich nutty flavor.
- Panko Breadcrumbs: 1/2 cup panko breadcrumbs tossed with 1 tablespoon olive oil and Italian seasoning for a crunchy toasted topping.
- Garlic & Italian Seasoning: Minced fresh garlic, dried oregano, dried basil, salt, and black pepper.
How to Make Dump and Bake Chicken Parmesan Casserole (Step-by-Step)
1. Dump the Pasta, Chicken & Liquid: Preheat your oven to 400°F (200°C). In a 9×13-inch baking dish, combine the uncooked penne pasta, cubed raw chicken breasts, marinara sauce, chicken broth, minced garlic, and Italian seasoning.

2. Stir to Submerge the Pasta: Stir the mixture thoroughly, ensuring all the pasta and chicken pieces are evenly distributed and fully submerged beneath the liquid.

3. Cover & Bake, Then Add Toppings: Cover the baking dish tightly with aluminum foil. Bake for 30 minutes. Remove the foil and scatter the shredded mozzarella cheese and the Parmesan-panko mixture evenly across the top.

4. Bake Uncovered to Golden Perfection: Return the casserole to the oven uncovered for 10 to 15 minutes, until the cheese is bubbly and melted and the panko topping is deeply golden brown and crisp.

5. Rest & Garnish: Let the casserole rest for 5 minutes before serving so the sauce thickens nicely. Garnish with freshly chopped basil or parsley and serve warm!
Chef's Helpful Tips
- Cover tightly with foil: A tight foil seal traps steam inside the dish, which ensures the uncooked penne cooks evenly and becomes perfectly tender
- Cut chicken into uniform 1-inch pieces so they cook through at the exact same time as the pasta
Delicious Variations & Add-Ins
- Vegetable Boost: Fold in 2 cups of fresh baby spinach, chopped bell peppers, or sliced mushrooms before baking.
- Spicy Kick: Add 1/2 teaspoon of red pepper flakes into the marinara base for an Arrabbiata-style heat.
- Gluten-Free Option: Use your favorite sturdy gluten-free penne (like brown rice or corn-based penne) and gluten-free panko breadcrumbs.
Storing & Reheating Instructions
To Store: Let leftovers cool completely. Store in an airtight container in the refrigerator for up to 4 days.
To Reheat: Reheat individual portions in the microwave for 1-2 minutes, or warm the entire baking dish in a 350°F (175°C) oven for 15 minutes until bubbly.
Frequently Asked Questions
Do I really not need to cook the pasta first?
Yes! Uncooked pasta bakes directly in the baking dish by absorbing the marinara sauce and chicken broth under the sealed aluminum foil.
Can I use leftover cooked chicken or rotisserie chicken?
Absolutely! If using precooked or shredded rotisserie chicken, stir it in with the pasta and sauce. The bake time remains the same so the pasta cooks through.
What side dishes pair best with this chicken casserole?
Serve with warm garlic bread, a crisp Caesar salad, or roasted green beans for a complete family meal.
