Rinse the chicken breasts under cold water and pat them dry with paper towels. Pound them to an even thickness of about 1 inch.

In a shallow dish, mix the bread crumbs, half of the grated Parmesan cheese, Italian seasoning, salt, and black pepper.

In another bowl, beat the eggs and milk together until well combined. Place the flour in a third dish.

Heat olive oil in a large skillet over medium heat. Dredge each chicken breast in flour, dip in the egg mixture, and then coat with the breadcrumb mixture.

Add the coated chicken breasts to the skillet and cook for about 3-4 minutes on each side until golden brown.

Transfer the cooked chicken to a baking dish. In a small bowl, combine the remaining grated Parmesan cheese, shredded mozzarella cheese, and minced garlic. Sprinkle this mixture over the chicken.

Bake in a preheated oven at 350°F (175°C) for 20-25 minutes, or until the chicken is cooked through and the cheese is bubbly and golden.
