Preheat the air fryer to 200°C (390°F). In a large bowl, toss the potato wedges with oil, salt, pepper, paprika, garlic powder, onion powder, and cayenne (if using) until evenly coated. Place the seasoned wedges in the air fryer basket in a single layer, avoiding overcrowding. Cook for 15-20 minutes, shaking the basket halfway through for even crispiness. Serve hot with your favorite dipping sauce.
