Ingredients You’ll Need

Simple, everyday ingredients come together beautifully in this Chicken Parmesan Casserole. Each component brings something essential: flavor, texture, or that irresistibly melty cheese factor.

Cooked chicken breast: Shredded or cubed chicken forms the hearty base—use leftovers or rotisserie for convenience.
Marinara sauce: Opt for a good-quality sauce to layer in deep tomato flavor and a hint of sweetness.
Garlic powder: Adds a punch of savory warmth without fresh chopping required.
Italian seasoning: This dried blend infuses the casserole with herby fragrance and classic Italian taste.
Shredded mozzarella cheese: Melts into gooey, stretchy perfection, blanketing the chicken in cheesy goodness.
Grated Parmesan cheese: Gives both sharp, salty bite and a savory finish in the topping layer.
Panko breadcrumbs: These Japanese-style crumbs create the crispiest, crunchiest golden topping.
Olive oil: Tossed with the panko, it helps brown and crisp the topping beautifully.
Salt: A little bit seasons the topping and brings all the flavors together.
Fresh basil or parsley (optional): An aromatic, colorful finishing touch if you want to brighten up your casserole.

How to Make Chicken Parmesan Casserole

Step 1: Prep Your Baking Dish

Start by preheating your oven to 375°F (190°C) and lightly greasing a 9×13-inch baking dish. This ensures your Chicken Parmesan Casserole doesn’t stick, and you’ll get those delicious, golden edges!

Step 2: Layer the Chicken

Evenly spread the cooked chicken—shredded or cubed—across the bottom of your baking dish. This forms the hearty base and captures all the juices and flavor from what goes on top.

Step 3: Add Marinara and Seasonings

Pour your marinara sauce across the chicken, making sure every bite is coated for tangy, saucy goodness. Sprinkle the garlic powder and Italian seasoning over the top to let those Italian flavors shine through in every forkful.

Step 4: Pile On The Cheeses

Scatter the shredded mozzarella over the saucy chicken, then sprinkle on half of the Parmesan cheese. This combination melts into a cheesy, savory blanket that’s the heart of Chicken Parmesan Casserole magic.

Step 5: Make and Add the Crunchy Topping

In a small bowl, mix panko breadcrumbs with olive oil, salt, and the remaining Parmesan cheese. Stir until the crumbs are evenly coated, then sprinkle generously over the cheese layer for that signature golden crunch.

Step 6: Bake

Slide your casserole into the oven and bake for 25–30 minutes. You’ll know it’s done when the top is bubbling, golden, and irresistibly crisp, signaling your Chicken Parmesan Casserole is ready to devour.

Step 7: Garnish and Serve

When it comes out of the oven, add a sprinkle of fresh basil or parsley if you like—this adds freshness, pops of color, and classic Italian aroma to your finished dish.

Make Ahead and Storage

Storing Leftovers

Store leftovers in an airtight container in the refrigerator. Chicken Parmesan Casserole stays fresh and delicious for up to 3 days, making it great for lunch or a quick dinner later in the week.

To freeze, let the casserole cool completely, then wrap tightly in plastic wrap and foil. It’ll keep in the freezer for up to 2 months. Thaw overnight in the fridge for the best texture before reheating.

Reheating

Reheat single servings in the microwave until heated through, or warm the whole casserole (covered with foil) in a 350°F oven. A couple of minutes under the broiler will revive that crispy, golden topping!
