01 - Preheat the oven to 430°F and line a large baking sheet with parchment paper.
02 - Slice each potato lengthwise into 8 uniform wedges.
03 - In a large mixing bowl, combine potato wedges with olive oil, garlic powder, paprika, dried rosemary if desired, salt, and black pepper. Toss thoroughly to ensure even coating.
04 - Arrange the seasoned wedges in a single layer on the prepared baking sheet, with skin-side down whenever possible.
05 - Bake in the center of the oven for 30–35 minutes, turning the wedges once halfway through, until they are crisp on the edges and tender inside.
06 - Remove the wedges from the oven, garnish with chopped fresh parsley if desired, and serve promptly.
