Preheat the oven to 400°F (200°C). Coat the chicken breasts with bread crumbs, pressing gently to adhere. Place the chicken breasts on a baking sheet and bake for 25 minutes until golden and crispy.
Remove the chicken from the oven and spread marinara sauce evenly over each breast. Top with shredded mozzarella and a sprinkle of Parmesan cheese.
Return the chicken to the oven and bake for an additional 5 minutes, or until the cheese is melted and bubbly.
Serve the Chicken Parmesan Bake hot, over pasta or with garlic bread. Enjoy!
