01 - Preheat oven to 430°F (220°C) and line a large baking sheet with parchment paper.
02 - Cut each potato lengthwise into 8 equal-sized wedges.
03 - In a large mixing bowl, combine potato wedges, olive oil, garlic powder, paprika, rosemary if using, salt, and pepper. Toss until all wedges are thoroughly coated.
04 - Place the seasoned potato wedges in a single layer on the prepared baking sheet, keeping skin-side down as much as possible.
05 - Bake for 30 to 35 minutes, turning the wedges once halfway through, until they are golden and crisp on the edges and tender inside.
06 - Remove from oven, sprinkle with chopped parsley if desired, and serve hot.
