Ingredients You’ll Need

These ingredients are straightforward yet essential, each playing a key role to build the warm, comforting, and wonderfully cheesy character of the Chicken Parmesan Casserole. From the perfectly seasoned chicken to the robust marinara sauce, everything blends together to create that classic Italian-inspired magic.

• Chicken breasts (1 ½ lb, diced): Skinless and boneless for easy cooking and bite-sized pieces that soak up all the flavor.
• Garlic cloves (4, minced): Adds a fragrant punch and warmth to the chicken seasoning.
• Italian seasoning (1 tbsp): A blend of herbs that bring authentic Italian aromas and taste.
• Oregano (1 tsp): Enhances the herbaceous profile with its earthy notes.
• Rigatoni pasta (16 oz, uncooked): Sturdy tubes that hold sauce beautifully and stay wonderfully al dente.
• Marinara sauce (24 oz jar): The rich tomato base that ties all the flavors together.
• Water (3 cups): Essential to cook the pasta directly in the casserole, making prep a breeze.
• Salt (1 tsp): Balances and deepens all the flavors.
• Black pepper (½ tsp): Adds a subtle sharpness and warmth.
• Mozzarella cheese (2 cups shredded): Creates that irresistible gooey melted layer on top.
• Panko breadcrumbs (1 cup): Provide a delightfully crunchy contrast when baked.
• Parmesan cheese (½ cup grated): Brings a savory, nutty finish with a golden crust.
• Fresh basil (chopped): Adds a fresh herbal brightness just before serving.

How to Make Chicken Parmesan Casserole

Step 1: Prepare the Oven and Chicken

Start by preheating your oven to 425°F and giving a 9×13 baking dish a quick spray with oil to prevent sticking. Then, toss the diced chicken breasts with minced garlic, Italian seasoning, and oregano in a bowl. Letting the chicken sit for a few minutes helps those aromatic flavors seep in, setting the tone for the entire dish.

Step 2: Assemble the Base Ingredients

Next, add the uncooked rigatoni, marinara sauce, water, the seasoned raw chicken, salt, and pepper directly into the prepared baking dish. This step is pure magic because you’re combining everything in one place, making cleanup a snap. Give the ingredients a good stir to ensure every bite is perfectly flavorful and the pasta starts soaking up the sauce and juices.

Step 3: First Bake—Cook the Pasta and Chicken

Cover the casserole tightly with aluminum foil to trap steam and moisture, then bake for 30 minutes. At this point, the pasta will soften and the chicken begins cooking through, all without needing to pre-boil anything. It’s a total time-saver and builds a beautiful depth of flavor as the sauce and seasonings mingle.

Step 4: Add the Cheesy Topping

Remove the foil and give the casserole a gentle stir; don’t worry if some liquid remains, the pasta will finish cooking. Now it’s time for the star layer: sprinkle shredded mozzarella, panko breadcrumbs, and grated Parmesan cheese evenly over the top. This combination guarantees a golden, bubbly crust that contrasts perfectly with the saucy layers underneath.

Step 5: Final Bake—Brown and Bubble

Pop the uncovered casserole back in the oven for another 10 to 15 minutes. Watch for that gorgeous golden-brown cheese crust and tender pasta texture. Once it reaches perfection, pull it out and scatter fresh chopped basil on top for a pop of color and fresh herbal flavor.

How to Serve Chicken Parmesan Casserole

Garnishes

A sprinkle of freshly chopped basil isn’t just pretty; it awakens the casserole with its vibrant aroma and adds a bright, fresh contrast to the rich, cheesy layers. If you want to get fancy, a light drizzle of extra virgin olive oil or a scattering of red pepper flakes can also elevate each serving beautifully.

Side Dishes

Because the Chicken Parmesan Casserole is hearty and full of flavor, it pairs wonderfully with lighter sides like a crisp green salad with a lemon vinaigrette or simple steamed vegetables like broccoli or green beans. Garlic bread or toasted baguette slices are also great options if you want to soak up every last bit of that luscious marinara sauce.

Creative Ways to Present

Serve this casserole straight from the baking dish for a casual, family-style experience that encourages everyone to dig in. For a more elegant presentation, portion servings onto individual plates, garnish with fresh basil leaves, and add a parmesan crisp on top. You can even layer it in small ramekins for charming, individual casseroles that make any meal feel special.

Make Ahead and Storage

Storing Leftovers

Store any leftover Chicken Parmesan Casserole in an airtight container in the refrigerator. It will keep beautifully for up to 3 days while maintaining its flavors and texture. Simply cover and refrigerate it promptly after serving to enjoy later without losing any of the deliciousness.

Freezing

This casserole freezes really well, making it a perfect meal prep candidate. Let it cool completely, then transfer portions to freezer-safe containers or wrap the entire dish tightly with foil and plastic wrap. It can be frozen for up to 2 months. When you’re ready to enjoy, thaw overnight in the fridge before reheating.

Reheating

To reheat, warm individual portions in the microwave until hot and bubbly. For a crispy top akin to freshly baked, reheat leftovers in a 350°F oven uncovered for about 15-20 minutes. Keep a close eye to avoid drying it out, and consider adding a sprinkle of extra cheese before warming for that fresh-from-the-oven feeling.

FAQs

Can I use a different type of pasta?

Absolutely! While rigatoni is perfect for holding sauce and layers, penne, ziti, or even small shells work wonderfully in the Chicken Parmesan Casserole. Just make sure to keep the pasta uncooked when assembling since it cooks in the oven.

Is it necessary to use raw chicken?

Using raw diced chicken in this recipe is part of what makes the casserole so easy, because the chicken cooks right in the sauce while baking. If you prefer, you can brown the chicken beforehand for extra flavor, but it’s not required.

Can I make this dish vegetarian?

Definitely! Swap the chicken for hearty vegetables like mushrooms, eggplant, or zucchini, and you’ll still get a delicious, comforting casserole. You might want to add extra Italian seasoning or some plant-based protein for that satisfying bite.

What if I don’t have panko breadcrumbs?

You can use regular breadcrumbs or crushed crackers as a substitute to get that crispy topping. For a gluten-free option, crushed gluten-free crackers or almond flour can also work nicely to create a golden crust.

Can I prepare the casserole ahead and bake it later?

Yes, you can assemble the casserole up to the point before baking, cover tightly, and refrigerate for up to 24 hours. When ready, bake covered for 30 minutes, then proceed with adding the cheese and breadcrumbs topping followed by the final bake uncovered.
