01 - Preheat the oven to 430°F (220°C) and line a large baking sheet with parchment paper.
02 - Cut each potato lengthwise into eight even wedges.
03 - In a large mixing bowl, combine the potato wedges with olive oil, garlic powder, paprika, rosemary (if using), salt, and ground black pepper, tossing to coat evenly.
04 - Distribute the seasoned wedges in a single layer on the prepared baking sheet, placing them skin-side down if possible.
05 - Bake for 30 to 35 minutes, flipping the wedges halfway through, until the edges are golden and crisp and the centers are tender.
06 - Remove from the oven, sprinkle with chopped fresh parsley, and serve immediately while hot.
