01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or lightly grease with cooking spray.
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 kitchen towel.
04 - In a large bowl, 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, then carefully flip each wedge using tongs. Continue baking for another 15–20 minutes, or until golden brown and crispy on the edges.
07 - Remove from the oven. Sprinkle with chopped parsley and grated Parmesan cheese if using. Serve immediately while hot and crispy.
