01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper or grease lightly with oil.
02 - Cut each potato lengthwise in half, then slice each half into 3 to 4 wedges, yielding 6 to 8 wedges per potato.
03 - Toss the potato wedges in a large bowl with olive oil, garlic powder, smoked paprika, onion powder, sea salt, black pepper, and oregano until evenly coated.
04 - Place the wedges in a single layer on the baking sheet, skin side down, spacing them apart to ensure even crisping.
05 - Bake for 20 minutes until golden around the edges.
06 - Flip each wedge and bake for an additional 15 minutes or until fully crispy and golden brown.
07 - Remove wedges from the oven, garnish with chopped parsley and Parmesan cheese if desired, and serve hot.
