Avocado oilor oil of your choice, no aerosol spray
Wash and scrub your sweet potatoes so they are clean and free from dirt.
Pierce your potatoes with a fork, 4-5 times
Place potatoes in the air fryer basket and spray with oil. You do not want to use an aerosol spray oil, this can ruin your air fryer. Massage oil into the sweet potatoes.
Sprinkle and rub in kosher salt
Bake sweet potatoes anywhere from 375˚F/191˚C - 400˚F/204˚C (I did 380˚F/193˚C) for 40 minutes. At the halfway point, carefully flip potatoes over.
After they finish cooking, give your sweet potatoes a squeeze. If your potatoes need more time, add a couple of minutes until they are cooked to desired tenderness. The cooking time really depends on the size of your potatoes, so you will just have to watch it carefully.
The cooking time will depend greatly on the manufacturer of your air fryer and the size of your potatoes. So, just keep an eye on your potatoes, and pull them out when you think they are ready! If you are cooking sweet potatoes for multiple people, remember to not over crowd your basket. Leave room for air to flow, so that your sweet potatoes can bake!
