In a large bowl, toss sweet potatoes with oil and all seasonings.
Place potatoes in air fryer basket. If using Instant Pot air fryer, put the basket into the inner pot, place the air fryer lid on top.
Set the temperature on the air fryer to 400 degrees and cook potatoes for 10 minutes.
Remove air fryer basket (or remove lid if using Instant Pot air fryer) and stir potatoes. Continue to cook potatoes until they are golden and tender (about 4-5 more minutes, but you can go longer if you prefer a crispier potato).
Remove and top with additional salt and pepper if desired. Serve and enjoy!
Notes
Try to cut potatoes as close to the same size as possible - this will help them cook evenly.
Make sure to shake them after they cook for 10 minutes because it helps the potatoes to evenly cook.
