Preheat the oven to 400°F (200°C). Place chicken breasts between two sheets of plastic wrap and pound to an even thickness.

Set up a breading station with three shallow dishes: one with flour, one with beaten eggs, and one with a mixture of bread crumbs, Parmesan cheese, salt, pepper, and garlic powder.

Dip each chicken breast in flour, then in egg, and finally coat with the breadcrumb mixture.

In a skillet over medium heat, add olive oil. Once hot, add the breaded chicken and cook for 4-5 minutes on each side until golden brown.

In a baking dish, spread half of the marinara sauce. Place the cooked chicken on top, then cover with the remaining sauce and sprinkle with mozzarella cheese.

Bake in the preheated oven for 15-20 minutes until the cheese is bubbly and golden.

Garnish with fresh basil and serve hot with pasta or a side salad.
