01 - Preheat your oven to 425°F. Line a large baking tray with parchment paper.
02 - Cut sweet potatoes lengthwise into wedges, approximately ¾ inch thick.
03 - In a large bowl, toss the sweet potato wedges with olive oil, smoked paprika, garlic powder, salt, pepper, and cayenne (if using) until evenly coated.
04 - Arrange the wedges in a single layer on the prepared baking tray, making sure they are not crowded for optimal crisping.
05 - Roast for 15 minutes, then flip the wedges and roast for another 15 minutes or until golden, crisp on the edges, and tender inside.
06 - Transfer to a serving platter, sprinkle with parsley, and serve with lemon wedges if desired.
