How to Make Dump-and-Bake Chicken Parmesan Casserole

Step 1: Preheat and Prepare

Preheat your oven to 425°F (220°C). Lightly grease a 13×9-inch baking dish with nonstick spray.

Step 2: Mix Everything Together

In the prepared dish (or a large bowl), combine the uncooked penne, marinara sauce, water, salt, pepper, and diced chicken. For extra flavor, you can add garlic powder, onion powder, Italian seasoning, or crushed red pepper flakes.

Step 3: Cover and Bake

Spread the mixture evenly in the dish. Cover tightly with aluminum foil to trap steam and help the pasta cook properly. Bake for 30 minutes.

Step 4: Add the Toppings

Remove the foil and stir the casserole. The pasta will still be firm and there may be some liquid left—this is normal. Sprinkle mozzarella cheese evenly over the top, followed by Panko breadcrumbs and Parmesan cheese.

Step 5: Bake Until Golden

Return the dish to the oven, uncovered, and bake for another 10–15 minutes, until the cheese is melted, bubbly, and lightly browned, and the chicken is fully cooked through.

Step 6: Garnish and Serve

Remove from the oven, garnish with fresh chopped herbs if desired, and serve hot.

Tips for Success

• Use a metal baking dish for faster, more even cooking
• Make sure the foil is sealed tightly during the first bake
• Don’t overcook or the pasta may become mushy
• Taste a piece of pasta to check doneness before the final bake
