Preheat the oven to 425°F (218°C) and grease one or more baking sheets or line with parchment.
Prep the chicken: place breasts on a cutting board and slice each horizontally into 3–4 thin cutlets; alternatively, halve each breast and pound between plastic wrap to about 1/4-inch thick.
Set up a breading station with three shallow bowls: bowl 1 – flour; bowl 2 – beaten eggs; bowl 3 – mix bread crumbs, grated Parmesan, minced garlic, Italian seasoning, salt, and pepper, then pour in the melted butter and stir until combined.
Coat each cutlet by dredging first in flour (shake off excess), then dip in the beaten eggs, and finally press into the breadcrumb mixture to fully coat both sides.
Arrange the coated cutlets in a single layer on the prepared baking sheet, making sure they do not touch.
Bake for 12–15 minutes until the coating is crispy and the internal temperature of the chicken reaches 165°F (74°C).
Remove from the oven and transfer cutlets to a wire rack to stay crispy before serving.
