Wash the potatoes thoroughly and peel them. You can leave the peels on if you like.
Cut the potato into half lengthwise. Put the flat side down and cut into half again to create 4 pieces in all. Cut each piece into half to create a wedge.
Soak them in cold water for about 20-30 minutes. Rinse and dry the potatoes using a clean dish towel or paper towel.
Toss the potato wedges in a mixture of oil, garlic powder, paprika, and salt till completely coated.
Place in the air frying basket - don't overcrowd them. Depending on the size of your airfryer, you may have to make them in batches.
Air fry for about 16 minutes at 400°F. Pause the air frying at around 8 minutes and toss the fries to enable even cooking.
