Preheat the oven to 350°F (175°C) and grease an ovenproof or cast-iron skillet; set aside.
In a shallow dish, combine the vegetable oil and minced garlic.
In a second shallow dish, mix the panko breadcrumbs, grated Parmesan, garlic powder, and salt until evenly combined.
Dip one pounded chicken breast into the garlic oil, coating both sides.
Immediately press the chicken into the breadcrumb mixture, coating both sides and pressing firmly so crumbs adhere.
Place the breaded chicken breast in the prepared skillet and repeat the oil-and-crumb coating with the remaining breasts.
Bake the chicken in the preheated oven for 30–35 minutes, or until the chicken is no longer pink and a thermometer inserted into the thickest part registers 165°F (74°C).
Remove from the oven and, if desired, sprinkle with extra grated Parmesan before serving.
