01 - Preheat the oven to 425°F (220°C) and line a large baking sheet with parchment paper.
02 - Cut each potato in half lengthwise, then slice each half into 3 to 4 wedges, yielding 6 to 8 wedges per potato.
03 - In a large mixing bowl, toss the potato wedges with olive oil, smoked paprika, garlic powder, onion powder, dried oregano, salt, and black pepper until evenly coated.
04 - Place the wedges in a single layer with the skin side down on the prepared baking sheet, ensuring wedges do not touch.
05 - Bake for 30 to 35 minutes, flipping the wedges halfway through baking, until they are golden brown and crisp.
06 - Remove from oven, sprinkle with chopped parsley and grated Parmesan cheese if desired, then serve immediately.
