Preheat the oven to 400°F. Arrange the pork chops in an oven-safe baking dish in a single layer.
Drizzle with olive oil and rub it evenly over both sides of each chop. Sprinkle the ranch seasoning over the pork chops, coating both sides evenly.
Bake uncovered for 20 minutes, or until the pork chops are nearly cooked through.
Switch the oven to broil and broil for about 5 minutes, watching closely, until the tops are lightly browned. Remove from the oven, loosely tent with foil, and let rest for 10 minutes before serving.
