01 - Preheat the oven to 425°F and line a large baking sheet with parchment paper or lightly grease the surface.
02 - Cut each potato in half lengthwise, then cut each half into 3–4 wedges, aiming for even thickness throughout.
03 - Place the wedges in a large bowl, cover with cold water, and let soak for 15 minutes for extra crispiness. Drain and pat dry thoroughly with a clean towel.
04 - Toss the dried potato wedges with olive oil, garlic powder, smoked paprika, onion powder, oregano, salt, and pepper until evenly coated.
05 - Arrange the seasoned wedges on the prepared baking sheet in a single layer, skin side down, leaving space between each piece for proper air circulation.
06 - Bake for 20 minutes until the edges begin to turn golden.
07 - Flip each wedge and continue baking for another 15–20 minutes until golden brown and crisp on the edges.
08 - Remove from the oven, sprinkle with chopped parsley and Parmesan cheese if desired, and serve immediately.
