Peel and cut the potatoes into fries (thin but not 'shoestring'). Soak in water for 10 minutes. Drain and pat dry.
In a large mixing bowl, toss the potatoes with the melted ghee or oil, as well as the seasoning so that everything gets coated well.
Cook in the air fryer at 356°F for 16-20 minutes. After the first 8-10 minutes, toss the fries in the basket (be careful as it's hot) so all pieces get nice and crispy.
