01 - Preheat the air fryer to 400°F for 3 minutes.
02 - In a large bowl, toss the sweet potato cubes with olive oil, smoked paprika, garlic powder, sea salt, and black pepper until evenly coated.
03 - Place the sweet potato cubes in a single layer in the air fryer basket, working in batches if necessary to avoid overcrowding.
04 - Air fry for 12–15 minutes, shaking the basket halfway through, until the cubes are golden and crisp at the edges and fork-tender inside.
05 - Serve hot, optionally garnished with fresh herbs or a sprinkle of sea salt.
