Chicken Parmigiana Casserole: The Ultimate Italian-American Bake with Golden-Breadcrumb Excellence

A simplified, crowd-pleasing twist on the classic Italian favorite. This casserole features seared chicken breast pieces tossed in savory marinara and melted mozzarella, topped with a golden-brown Parmesan breadcrumb crust. Perfect for busy weeknights when you want those classic flavors without the individual breading and frying.

  • Total Time: 45 minutes
  • Yield: 4-6 servings 1x

Ingredients

Scale
  • 4 boneless, skinless chicken breasts
  • 1 cup marinara sauce (store-bought or homemade)

  • 2 cups mozzarella cheese, shredded (divided)

  • 1/2 cup grated Parmesan cheese

  • 1 cup breadcrumbs (plain or Italian-style)

  • 1 tablespoon Italian seasoning

  • 2 cloves garlic, minced

  • 1 tablespoon olive oil

  • Salt and freshly ground black pepper (to taste)

  • Fresh basil, chopped (for garnish, optional)

  • Nonstick cooking spray (for greasing)

Instructions

  • Prepare: Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

  • Season: Pat chicken dry. Season both sides with salt, pepper, and Italian seasoning.

  • Sear: Heat olive oil in a skillet over medium heat. Sear chicken for 3–4 minutes per side until golden (it won’t be fully cooked). Remove and let cool slightly.

  • Prep Chicken: Slice the seared chicken into bite-sized pieces or thin strips.

  • Mix: In a large bowl, toss the chicken with marinara sauce, 1 cup of mozzarella, and minced garlic.

  • Assemble: Transfer mixture to the baking dish in an even layer.

  • Topping: In a separate bowl, mix breadcrumbs, the remaining 1 cup of mozzarella, and Parmesan. Sprinkle evenly over the chicken.

  • Bake: Bake for 25–30 minutes until bubbling and the top is golden brown (internal temp should reach 165°F).

  • Finish: Optional: Broil for 2–3 minutes for extra crispiness. Let rest for 5 minutes, garnish with basil, and serve.

Notes

  • Serving Suggestion: Serve over a bed of al dente pasta or with a side of garlic bread and a crisp green salad.

  • Storage: Leftovers can be stored in an airtight container in the fridge for up to 3 days.
