Even quicker to cook are cubes of sweet potato, which take around 15 minutes to air fry. Simply peel and dice the tubers into cubes an inch in size, toss them in seasoned oil, then cook them in an air fryer pre-heated to 390 degrees Fahrenheit.

How to cook sweet potato cubes in the air fryer? Wash the sweet potatoes first and peel if you want. Later, cut them into cubes, then sprinkle salt, pepper, garlic, and spray oil on the chunks of sweet potato. Once loaded with the square chunks, take care not to overstock the basket of the fryer.

Air fry – preheat the air fryer to 400°F. If your air fryer does not have a preheat setting then heat the air fryer empty at 400°F for 2-3 minutes, before adding the sweet potato cubes.
