Remove the air fryer basket from the air fryer and preheat the air fryer to 415° F.
Put a piece of parchment paper in the air fryer basket.
Slice the yam into thin rounds to resemble chips. They should be no more than ⅛ inch, or about 3 mm thick.
Put the sliced yam on the parchment paper in the basket.
Place the basket in the air fryer. Set the timer for 16 minutes.
Check the Yam slices periodically to make sure they do not burn.
At 14 mins, take the air-fryer basket out of the air fryer and flip the yam slices (chips) over. Put them back in the air fryer for an additional 2 minutes. DO NOT LET THEM BURN!
