01 - Preheat the oven to 425°F. Line a large baking sheet with parchment paper.
02 - Cut the sweet potatoes into wedges: halve lengthwise, then cut each half into 4–6 thick wedges.
03 - In a large bowl, toss the sweet potato wedges with olive oil, smoked paprika, garlic powder, salt, pepper, and cayenne until well coated.
04 - Arrange the wedges in a single layer on the prepared baking sheet, leaving space between each wedge for even roasting.
05 - Roast for 25–30 minutes, flipping halfway through, until the wedges are golden brown and crisp on the edges.
06 - Transfer to a serving platter. Sprinkle with chopped parsley and serve with lemon wedges if desired.
