Preheat the oven to 400°F, then brush the olive oil onto a sheet pan.
Add your potatoes to a medium saucepan of salted water. Bring to a boil, then cook for 20-25 minutes, until the potatoes are fork-tender.
In a small mixing bowl, stir together the melted butter, garlic, garlic powder, onion powder, pepper, salt, and smoked paprika.
Place the potatoes on the sheet pan. Place a piece of parchment paper on top of a potato, using the bottom of a flat cup, and smash the potatoes until they are about a quarter inch thick. Brush the garlic butter over the potatoes. Sprinkle the potatoes with Parmesan cheese.
Bake for 30 to 40 minutes until the potatoes are crispy.
