Yes you can air fry the cubed potatoes with the auto option for French fries or preheat your air fryer for 5 mins at 360 F or 180 C. Then spread the cubed potatoes (1 inch pieces) in the basket and spray some oil. Air fry them for 10 to 12 minutes until crisp and golden. Toss them half way and air fry until crisp and fully cooked through.
