Equipment

  • 9x13 inch baking dish
  • Large skillet
  • Three shallow dishes (for breading station)
  • Cutting board
  • Chef's knife
  • Whisk
  • Tongs
  • Measuring cups and spoons
  • Oven

Ingredients
  

  • 2 lbs boneless, skinless chicken breasts, cut into 1-inch bite-sized pieces
  • ½ cup all-purpose flour
  • 1 tsp salt
  • ½ tsp black pepper
  • 2 large eggs, beaten
  • 1 ½ cups Panko breadcrumbs
  • ¾ cup grated Parmesan cheese, divided
  • 1 tbsp Italian seasoning
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • ¼ cup olive oil
  • 24 oz marinara sauce
  • 2 cups shredded low-moisture mozzarella cheese
  • ¼ cup fresh basil or parsley, chopped, for garnish

Instructions
 

  • Preheat your oven to 375°F (190°C).
  • Set up a breading station with three shallow dishes. In the first, combine the flour, salt, and pepper. In the second, whisk the eggs until smooth. In the third, mix together the Panko breadcrumbs, 1/2 cup of the grated Parmesan cheese, Italian seasoning, garlic powder, and onion powder.
  • Pat the chicken pieces dry with a paper towel. Working in batches, dredge each piece first in the flour mixture, then dip it completely in the egg, and finally, press it firmly into the Panko mixture to coat all sides.
  • Heat olive oil in a large skillet over medium-high heat. Carefully place the breaded chicken in the skillet in a single layer, avoiding overcrowding. Cook for 2-3 minutes per side, until golden brown and crispy. The chicken does not need to be fully cooked. Transfer the browned chicken to a plate.
  • Spread a thin layer (about 1/2 cup) of marinara sauce on the bottom of a 9x13-inch baking dish. Arrange the browned chicken pieces in an even layer over the sauce.
  • Pour the remaining marinara sauce over the chicken, ensuring it is fully covered. Sprinkle the shredded mozzarella and the remaining 1/4 cup of Parmesan cheese evenly over the top.
  • Bake for 20-25 minutes, or until the sauce is bubbly and the cheese is melted and golden brown. Ensure the chicken's internal temperature reaches 165°F (74°C).
  • Remove from the oven and let the casserole rest for 5-10 minutes. This allows it to set for easier serving. Garnish with fresh chopped basil or parsley before serving.

Notes

Variations & Tips:
- **Chicken:** Boneless, skinless chicken thighs can be used for a more tender result.
- **Gluten-Free:** Use a gluten-free 1-to-1 flour blend and gluten-free Panko breadcrumbs.
- **Cheese:** Mix in Provolone with the mozzarella for a sharper flavor, or use torn fresh mozzarella balls (bocconcini) for creamier pockets of cheese.
- **Spice it Up:** Add 1/2 teaspoon of red pepper flakes to the breading or marinara for a kick of heat.
- **Level Up:** Add a layer of sautéed spinach or mushrooms, or mix browned Italian sausage into the marinara sauce for extra richness.
- **Avoid Soggy Chicken:** Ensure your oil is hot before searing and work in batches to avoid steaming the chicken. Do not let the breaded chicken sit for too long before cooking.
- **Serving Suggestions:** Pairs perfectly with a simple green salad, garlic bread, or served over pasta like spaghetti or penne.
