Ingredients You’ll Need

Incredible dishes start with simple ingredients, and this Dump-and-Bake Chicken Parmesan Casserole is no exception. Each component plays a vital role, from the pasta lending substance to the chicken packing protein, while the cheeses add richness and gooey texture. The marinara provides that familiar tang, and a sprinkle of seasoning ties it all together perfectly.

• Uncooked penne pasta (1 16-oz package): The perfect pasta shape to hold sauce and cheese in every bite.
• Marinara sauce (3 cups): Choose a good-quality jar for a robust, tangy foundation.
• Water (3 cups): Helps cook the pasta perfectly right in the casserole dish.
• Salt (1 tsp): Enhances flavors and seasons the pasta as it cooks.
• Ground black pepper (to taste): Adds a subtle kick that highlights the other savory elements.
• Raw chicken breast (1 ½ lbs), cut into bite-sized pieces: Tender chicken cooks directly in the sauce, ensuring juicy, flavorful bites.
• Shredded mozzarella cheese (1-2 cups): Melts beautifully for that crave-worthy cheese pull.
• Grated Parmesan cheese (½ cup): Gives a nutty, sharp touch that elevates the dish.
• Panko breadcrumbs (1 cup): Adds a golden, crunchy topping that balances the creamy casserole.
• Optional fresh chopped herbs (basil or parsley): For a bright, fresh finish and vibrant color.

How to Make Dump-and-Bake Chicken Parmesan Casserole

Step 1: Combine the Pasta and Liquids

Start by spreading the uncooked penne pasta evenly in your casserole dish. Pour in the marinara sauce and water, sprinkle the salt and pepper over the top, then gently stir everything together until the pasta is mostly coated and submerged. This step is key because the pasta will cook in this very mixture, soaking up all those luscious flavors.

Step 2: Add the Chicken

Next, scatter the diced raw chicken breast evenly over the pasta mixture. You want those chunks to be submerged in the sauce for even cooking. No need to pre-cook the chicken because the baking process will cook it through and infuse it with the marinara’s richness.

Step 3: Layer on the Cheese

Sprinkle the shredded mozzarella and grated Parmesan evenly across the top of the casserole. This cheesy blanket will melt and bubble, creating that irresistible golden layer that makes this dish truly special.

Step 4: Add the Panko Topping

Generously cover the cheese with panko breadcrumbs. This topping transforms into a crunchy contrast against the creamy, saucy pasta and tender chicken, making each bite more exciting.

Step 5: Bake Until Bubbly and Golden

Pop the casserole into a preheated oven at 375°F (190°C) and bake for about 45-50 minutes. You’ll know it’s ready when the sauce is bubbling, the cheese is melted and bubbling, and the panko topping has turned a delicious golden brown. Let it rest for a few minutes before digging in to let everything set and flavors meld.

How to Serve Dump-and-Bake Chicken Parmesan Casserole

Garnishes

Fresh herbs like chopped basil or parsley sprinkled on top add a lovely pop of color and a fresh layer of flavor that complements the rich casserole. A light drizzle of extra virgin olive oil can also elevate the dish with an aromatic touch.

Side Dishes

This casserole pairs beautifully with crisp green salads to add freshness or roasted vegetables like asparagus or broccoli, which provide a nice textural balance and earthy undertones. Garlic bread or a warm baguette is perfect for soaking up any extra sauce on your plate.

Creative Ways to Present

Serve this Dump-and-Bake Chicken Parmesan Casserole family-style in the baking dish for casual meals, or scoop portions individually into bowls layered with a sprinkle of extra cheese and fresh herbs for a restaurant-worthy presentation. For entertaining, try topping each serving with a few fried basil leaves or a Parmesan crisp for added flair.

Make Ahead and Storage

Storing Leftovers

Leftover Dump-and-Bake Chicken Parmesan Casserole keeps wonderfully in an airtight container in the refrigerator for up to 3 days. The flavors actually continue to develop, making it a delicious next-day meal. Just be sure to cover tightly so the casserole doesn’t dry out.

Freezing

If you want to prep in advance, assemble the casserole but don’t bake it; cover tightly with foil and freeze for up to 3 months. When you’re ready to enjoy, bake it covered from frozen at 375°F (190°C) for about 60-70 minutes until hot and bubbly, then remove the foil to let the topping crisp up in the final 10 minutes.

Reheating

To reheat leftovers, cover and microwave individual portions until warmed through, about 2-3 minutes. For best texture, reheat in a preheated oven at 350°F (175°C) for 15-20 minutes to bring back the crispy topping and melty cheese experience.

FAQs

Can I use a different type of pasta?

Absolutely! While penne works perfectly here for its shape and ability to hold sauce, other short pasta like rigatoni, ziti, or even rotini will work well. Just keep in mind cooking times may vary slightly.

Do I need to thaw the chicken first?

For best results, use fresh or fully thawed chicken breast cut into pieces. This ensures even cooking throughout the casserole without parts being undercooked or dry.

Can I make this recipe vegetarian?

Yes! Substitute the chicken for vegetables like mushrooms, zucchini, or eggplant and add extra cheese for protein and richness. The Dump-and-Bake Chicken Parmesan Casserole is very versatile and adapts well.

Is it possible to use homemade marinara sauce?

Definitely! Homemade marinara adds a wonderful depth of flavor and makes the dish feel even more special. Just be sure your sauce is well seasoned to balance the casserole.

How can I make the topping extra crispy?

Try tossing the panko breadcrumbs with a little olive oil or melted butter before sprinkling them on top. This helps achieve a golden, crunchy crust that contrasts beautifully with the creamy casserole.
