Ingredients You’ll Need

The beauty of Chicken Parmesan Casserole lies in its straightforward ingredient list—yet each element plays a starring role for both taste and texture. Whether you start with leftover rotisserie chicken or make it fresh, these ingredients come together to make magic in your casserole dish.

• Cooked and shredded chicken breast (3 cups): Tender and hearty, the shredded chicken acts as the protein-packed base, absorbing all the savory flavors.
• Marinara sauce (2 cups): Classic Italian tomato sauce brings a burst of bright, tangy flavor and keeps every bite moist.
• Italian seasoning (1 teaspoon): This blend infuses the dish with aromatic herbs for an unmistakable Mediterranean vibe.
• Garlic powder (½ teaspoon): Adds savory depth and warmth, enhancing the marinara and overall flavor.
• Shredded mozzarella cheese (2 cups): Melts into gooey perfection, binding everything together with a delicious stretch.
• Grated Parmesan cheese (½ cup): Salty and nutty, Parmesan adds that authentic cheesy tang you expect from anything “Parmesan-style.”
• Garlic croutons or seasoned breadcrumbs (1½ cups): The key to crunch! Choose your favorite for maximum flavor and texture contrast.
• Melted butter (2 tablespoons): Helps brown the topping and ensures every crumb is golden and tasty.
• Chopped fresh basil or parsley (optional): A sprinkle of fresh herbs at the end brings brightness, color, and a touch of elegance.

How to Make Chicken Parmesan Casserole

Step 1: Get Ready to Bake

Preheat your oven to 375°F (190°C) and grab a 9×13-inch baking dish. A light coat of nonstick spray or a dash of oil ensures nothing sticks and cleanup is a breeze, letting you focus on flavor.

Step 2: Lay Down the Chicken

Spread the cooked, shredded chicken evenly across the bottom of your prepared baking dish. This is the hearty base that will soak up all the other flavors and keep every forkful meaty and satisfying.

Step 3: Mix the Marinara Magic

In a mixing bowl, combine the marinara sauce with Italian seasoning and garlic powder. Stir well—this infuses the sauce with herb-and-garlic goodness. Pour it evenly over the chicken, letting the juices mingle and create a saucy foundation.

Step 4: Cheese, Please!

Sprinkle shredded mozzarella cheese and grated Parmesan cheese over the marinara-topped chicken. Don’t be shy—this layer is what gives Chicken Parmesan Casserole its signature oozy, cheesy appeal.

Step 5: Crunch Time

In a small bowl, toss the garlic croutons or seasoned breadcrumbs with melted butter until each piece is lightly coated. Scatter this mixture over the cheese, forming an even layer. This step is what gives the casserole its irresistible, crispy crust.

Step 6: Bake to Golden Perfection

Slide the casserole into the preheated oven and bake for 25 to 30 minutes. You’ll know it’s ready when the cheese is bubbly, gooey, and the topping is temptingly golden brown. Let it rest a few minutes before serving, so it sets up just right.

How to Serve Chicken Parmesan Casserole

Garnishes

Finish your Chicken Parmesan Casserole with a vibrant sprinkle of chopped fresh basil or parsley. This simple touch adds color, a pop of freshness, and just the right hint of herbal aroma right before digging in.

Side Dishes

This casserole is a star on its own, but it pairs beautifully with a crisp green salad or buttery garlic bread. For a heartier meal, try serving it atop cooked pasta or with simple roasted vegetables to soak up all that saucy, cheesy goodness.

Creative Ways to Present

For a fun twist, spoon portions into individual ramekins for a dinner party-worthy presentation, or serve over a bed of spaghetti for a true Italian-American feast. If you love a little heat, a dusting of red pepper flakes or a drizzle of pesto right before serving makes this Chicken Parmesan Casserole extra special.

Make Ahead and Storage

Storing Leftovers

Leftovers (if there are any!) can be stored in an airtight container in the refrigerator for up to three days. The flavors meld overnight, making the next-day servings just as satisfying, if not more.

Freezing

This casserole is freezer-friendly—perfect for meal prep or busy weeks. Assemble and freeze before baking for best results, tightly wrapped. If already baked, let cool completely before wrapping and freezing in portions. It keeps well for up to 2 months.

Reheating

To reheat, bake leftovers at 350°F (175°C) until warmed through and the topping is crisp again, about 15–20 minutes. For single portions, the microwave works in a pinch, but a quick trip under the broiler restores that delicious crunch.

FAQs

Easy! Arrange cooked pasta in the dish before adding the chicken layer. You’ll create a one-pan pasta bake with all the flavor and comfort you crave—it’s a win for pasta lovers.
