1/2tspsaltif you want salt on the outside for a salty/sweet flavor
Wash your sweet potatoes. Use a fork to poke all around each one, top and bottom.
Rub olive oil on the outside of each sweet potato. Using your hands works best.
If you want to add salt to the outside to create a salty/sweet taste then sprinkle salt on the outside of each one at this time.
Put on the air fryer rack inside your air fryer. If you have the Ninja Foodi turn the metal rack upside down and set your potatoes on top.
Set temp to 390 degrees for 35 minutes. (timing will vary slightly depending on how big your potatoes are, it is suggested to put 4 of the same size in at a time)
Remove immediately, slice, fluff the middle and add toppings such as butter and/or mixture of cinnamon and sugar.Can also use this recipe to make homemade sweet potato casserole. Scoop out middle if doing that.
