01 - Set oven temperature to 425°F. Prepare a large baking sheet by lining with parchment paper or applying a light coat of oil.
02 - Halve each potato lengthwise, then slice each half into 3 to 4 wedges, producing approximately 6 to 8 wedges per potato.
03 - Place wedges in a large bowl and toss thoroughly with olive oil, garlic powder, smoked paprika, onion powder, sea salt, black pepper, and dried oregano until evenly coated.
04 - Lay wedges in a single layer on the prepared baking sheet with skin side down, ensuring space between each wedge for optimal crisping.
05 - Bake in the preheated oven for 20 minutes to begin crisping the edges.
06 - Flip each wedge carefully, then resume baking for an additional 15 minutes until golden brown and crisp.
07 - Remove wedges from oven. Sprinkle with chopped parsley and grated Parmesan cheese as desired. Serve immediately while hot.
