Preheat oven to 400°F. Line a rimmed baking sheet with foil.
On the foil-lined sheet: Drizzle then spread olive oil evenly with a pastry brush (or spray with nonstick cooking spray).
Pat pork chops dry and arrange on baking sheet.
In a small bowl, combine brown sugar, salt, pepper, garlic powder, onion powder, and smoked paprika. You will divide this mixture among the four chops. Set aside.
I recommend adding the ketchup to a small bowl so you easily use a pastry brush to spread it on the chops. You can also just squirt onto each one and then use the back of a spoon. (The ketchup will be divided among the four chops, so keep that in mind as you go.)
Dab ketchup over the top of each pork chop, then sprinkle about ½ teaspoon of sugar mixture onto each chop.
Bake uncovered for 15–20 minutes or until internal temperature of thickest part of the chop reaches 145°F.
Remove from the oven, cover loosely with foil, and rest 5 minutes before serving.
