Description

This Chicken Parmesan Casserole packs all the flavors of classic chicken Parm into one easy, crowd-pleasing bake. Tender shredded chicken is tossed in garlicky marinara, layered with melty mozzarella and Parmesan, then finished with a golden, crunchy breadcrumb topping for a cozy dinner that feels comforting yet weeknight simple.

Ingredients

Scale

4 cups cooked chicken, shredded (rotisserie chicken works great)
2 cups marinara sauce
2 cups mozzarella cheese, shredded, divided
1 cup Parmesan cheese, grated, divided
1 cup breadcrumbs (plain or Italian-style)
1 tablespoon Italian seasoning
2 cloves garlic, minced
1 tablespoon olive oil
Salt and pepper to taste
Fresh basil, chopped or torn, for garnish

Instructions

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set aside.
In a large mixing bowl, combine the shredded chicken, marinara sauce, half of the mozzarella cheese, half of the Parmesan cheese, minced garlic, Italian seasoning, salt, and pepper. Stir until the chicken is evenly coated and everything is well mixed.
Transfer the chicken mixture to the prepared 9×13-inch baking dish, spreading it out into an even layer.
In a separate bowl, add the breadcrumbs, remaining mozzarella cheese, and remaining Parmesan cheese. Drizzle with the olive oil and toss until the breadcrumbs are evenly coated and slightly moistened.
Sprinkle the breadcrumb-cheese mixture evenly over the chicken layer, covering it completely for a crunchy topping.
Bake in the preheated oven for 25–30 minutes, or until the top is golden brown, the cheese is melted, and the casserole is hot and bubbly around the edges.
Remove from the oven and let the casserole cool for 5–10 minutes to set slightly before serving.
Garnish with chopped or torn fresh basil just before serving for a bright, fresh finish.

Notes

Use a flavorful marinara you love, since it’s the main sauce and really drives the overall taste of the casserole.
Rotisserie chicken or leftover roasted chicken makes this recipe especially quick and convenient.
The casserole will thicken slightly as it cools, so a short rest time makes it easier to scoop neat portions.
