Scrub the sweet potatoes and cut into ½-inch cubes (peeling is optional; we leave our peels on).
Place in a large bowl and toss with the oil, salt, smoked paprika, garlic powder, and black pepper.
Place in the air fryer basket and air fry at 400°F for about 12 minutes, shaking the basket halfway through.
The potatoes should be dark in spots on the outside and tender inside; check a few minutes early just to be safe as all air fryers are different.
Serve warm, with a sprinkle of salt to taste.
