01 - Preheat the oven to 430°F and line a large baking sheet with parchment paper.
02 - Cut each potato lengthwise into 8 wedges for uniform size.
03 - In a large mixing bowl, toss the potato wedges with olive oil, garlic powder, paprika, rosemary if desired, salt, and black pepper until thoroughly coated.
04 - Place the seasoned wedges in a single layer on the prepared baking sheet, ideally with the skin-side down.
05 - Bake for 30 to 35 minutes, turning the wedges once halfway through, until they become golden brown and crisp on the edges while remaining tender inside.
06 - Once baked, remove from the oven. Sprinkle with chopped fresh parsley if desired and serve immediately while hot.
