Cut the potatoes into 1-inch cubes and transfer them to a large bowl. Toss them with the olive oil, garlic powder, onion powder, and salt, coating them evenly.
Transfer the potatoes into the air fryer basket, arranging them in a single layer. Cook for 15 minutes at 360ºF.
When the time is up, check on the potatoes and remove any small pieces that might be done. Shake the basket to turn the potatoes, then return to cook for another 5 minutes at 360ºF. The potatoes are done when they are golden on the outside, and easily pierced with a fork. Serve warm right away, as they will soften as they cool.
Baked Sweet Potatoes
Scrub the potatoes well, then dry and pierce each potato with a knife several times to vent. Rub the skins with olive oil and season generously with salt.
Place the potatoes in the air fryer basket, and cook at 400ºF for 45 minutes, or until the potatoes reach an internal temperature of 207ºF when you check them with a meat thermometer. (This timing is for an 8 oz. potato; see notes for other weights.)
Serve warm, with your favorite toppings. Leftover sweet potato can be used in a number of ways, so be sure to check out the recipe ideas mentioned in this post!
