Peel rutabagas, and slice into thick cut julienne fries. Toss fries with olive oil.
Put approximately half of the fries into the air fryer basket. If your air fryer is large enough to do more, you can, but mine fits about half of this recipe at a time.
Turn the air fryer to 400F for about 18 minutes. Shake the basket every 5 minutes or so to move the fries around a bit.
