Wash outside skin of sweet potatoes.
For rounds: Slice sweet potatoes equally to about ¼ inch for sweet potato rounds. If you want to make air fryer sweet potato chips, you will need to use a mandoline and slice very thin!
For fries: start by cutting the small ends and then cut the sweet potato in half. Then, put each half on its side and cutting four slices, making the wedges about the size of your pinkie finger.
Add cut sweet potatoes to a medium bowl. Coat with melted coconut oil. Season with spices and toss until well coated.
Add sweet potatoes to air fryer sprayed with coconut oil spray. Add potatoes in one layer, dividing them into a few batches if necessary.
For rounds: Air fry at 350F for 12 minutes. Turn up to 400F for 3 minutes. Thinner rounds will cook faster so if you are making air fryer sweet potato chips or haven't cut them to ¼ inch they will cook up faster.
For fries: Air fry at 400F for 12 minutes.
For whole potato: Use a fork to poke several holes around it. Then, wrap your potato in foil and it is ready to cook. Cook potato at 390F for 40-60 minutes depending on the size. Add seasonings or coconut oil/ghee after cooked.
