Preheat your oven to 400°F (200°C).
Flatten the chicken breasts to an even thickness using a meat mallet.
Season both sides of the chicken with salt, pepper, garlic powder, and Italian seasoning.
In a shallow bowl, mix breadcrumbs and Parmesan cheese.
Dip each chicken breast into the breadcrumb mixture, coating evenly.
Heat olive oil in a skillet over medium heat.
Fry the chicken breasts for 4-5 minutes on each side until golden brown.
Place the fried chicken in a baking dish.
Spoon marinara sauce over each chicken breast, then top with mozzarella cheese.
Bake in the oven for 15-20 minutes until the cheese is melted and bubbly.
