01 - Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper.
02 - In a large bowl, whisk together the olive oil, chili powder, smoked paprika, cumin, garlic powder, cayenne pepper (if using), sea salt, and black pepper.
03 - Add the sweet potato wedges to the bowl with the seasoning mixture. Toss thoroughly to ensure each wedge is evenly coated.
04 - Carefully arrange the seasoned sweet potato wedges in a single layer on the prepared baking sheet. Ensure there is adequate space between each wedge to promote crisping.
05 - Roast for 25 to 30 minutes, turning the wedges halfway through the cooking time, until they are golden brown, have crisp edges, and are tender on the inside.
06 - Remove the roasted wedges from the oven. Sprinkle with fresh cilantro, if desired, and serve immediately with lime wedges.
