Preheat the Oven to 425°F (220°C) and line a baking sheet with parchment paper.
Wash and cut sweet potatoes into 1 inch wedges.
In a small bowl, mix olive oil, minced garlic, smoked paprika, onion powder, salt, black pepper, and optional red pepper flakes.
Toss sweet potato wedges in the garlic oil mixture until well coated.
Sprinkle half of the Parmesan cheese over the wedges and toss again.
Arrange wedges in a single layer on the baking sheet without overcrowding.
Bake for 25-30 minutes, turning halfway through, until golden and crisp.
Remove from the oven and sprinkle remaining Parmesan cheese on top while hot.
Garnish with fresh parsley and serve immediately with your favorite dipping sauce or enjoy as is.
