In a shallow dish, whisk together the Parmesan cheese, breadcrumbs, garlic powder, onion powder, salt, and pepper.
In another shallow dish, vigorously whisk the eggs.
Add the flour to a separate dish.
Create a line-up of flour, eggs, and then breadcrumbs. Cover the first pork chop in a good amount of the flour (you should not see most of the pink anymore), then dip it in the eggs until fully covered, and then press into the breadcrumbs on both sides. Shake off excess and set aside on a wire rack or plate.
Repeat with remaining pork chops.
Heat the vegetable oil in a large pan on medium heat until hot but not quite smoking. Add the butter and once it is melted, add the pork chops and cook on each side for 3-5 minutes or until the internal temperature reaches 145℉
