Preheat the oven to 425°F, line a rimmed baking sheet with aluminum foil, and coat it with nonstick spray.
Whisk the egg and milk together in a shallow dish (a pie plate works well) and set aside.
In a small bowl, combine the breadcrumbs with the salt, garlic powder, onion powder, and a few grinds of black pepper, then spread them on a plate or sheet of wax paper.
One at a time, dip the chops in the egg mixture, then into the crumbs, pressing firmly to get an even coating. You can use the back of a spoon to gently press the crumbs onto the pork to be sure they adhere.
Transfer the chops to the prepared baking sheet and bake for 10 to 15 minutes (depending on thickness), until golden brown and cooked to an internal temperature of 140°F. For best results and even cooking, flip the chops over midway through cooking and rotate the pan when you return it to the oven.
Allow the chops to rest for 5 minutes before serving.
