Preheat oven to 390 degrees and prepare a baking sheet with foil. Spray foil with cooking spray.
Slice each potato in half lengthwise. Then cut the halves into thirds or fourths (depending on the size of the potato). I left the skin on the potatoes but you can peel them if you prefer.
In a small bowl, combine all of the dry ingredients - onion powder, garlic powder, paprika, salt, pepper and Parmesan Cheese.
Place potato wedges in a large mixing bowl and pour the oil over the wedges. Using your hands, make sure the wedges are completely covered with oil.
Add dry ingredients to the potatoes and making sure each wedge has seasoning.
Spread potato wedges over the prepared baking sheet in a single layer. Sprinkle additional seasoning over wedges if desired.
Bake for about 40 minutes, flipping them halfway through until they are golden brown and crispy.
Serve hot from the oven with your favorite dipping sauce! ENJOY!
