Preheat the oven to 400°F. Line a large rimmed baking sheet with foil for easy clean up and spray with non-stick spray.
Slice potatoes in half. Then slice each half into 4-5 wedges. Place in a zip top bag. Pour the olive oil, parmesan cheese, salt, garlic powder, pepper into the bag and shake until well coated. Spread out onto the pan, skin facing down.
Bake for 25-35 minutes, or until tender. Remove from oven and season with more salt and pepper if desired. Enjoy while hot!
For extra crispy wedges, soak in a bowl with warm water for about 10 minutes before baking.
