01 - Preheat oven to 425°F. Line a large baking sheet with parchment paper or lightly grease with oil.
02 - Cut each potato lengthwise into 8 to 10 wedges, maintaining consistent sizing for even cooking.
03 - Place potato wedges in a large mixing bowl. Add olive oil, garlic powder, smoked paprika, oregano, salt, and pepper. Toss thoroughly until all wedges are evenly coated.
04 - Distribute seasoned wedges in a single layer on the prepared baking sheet with skin side down, spacing them to prevent crowding.
05 - Bake for 35 to 40 minutes, flipping wedges halfway through cooking, until golden brown and crispy at edges.
06 - Remove from oven and garnish with chopped parsley and grated Parmesan cheese if desired. Serve immediately.
