01 - Preheat oven to 430°F (220°C). Line a large baking sheet using parchment paper.
02 - Slice russet potatoes lengthwise into 8 evenly sized wedges each.
03 - In a large mixing bowl, combine potato wedges with olive oil, garlic powder, paprika, rosemary, salt, and black pepper. Toss well to ensure even coating.
04 - Spread coated potato wedges out in a single layer on the prepared baking sheet, keeping the skin side down when possible.
05 - Transfer baking sheet to oven and bake for 30 to 35 minutes, flipping wedges halfway through. Bake until edges are golden and centers are tender.
06 - Remove from oven, garnish immediately with freshly chopped parsley, and serve hot.
