Preheat the air fryer to 400°F. Cut each potato into even ¼ inch thick sticks. Add potatoes to cold water and allow to soak for 15 minutes.
Drain out all of the water and place the potato wedges on a kitchen towel. Dry them well and place in a medium sized mixing bowl.
Sprinkle over the cornstarch and toss or mix with a spatula so that the potatoes get evenly coated. Toss with olive oil, salt, garlic powder, cayenne and black pepper.
Add the fries to the air fryer basket and air fry at 400°F for 12 mins. Shake Half way through. Add 2 minutes in the end for extra crispy!
Remember to cook in batches, depending on the size of your basket without overcrowding the basket until they’re crispy. I recommend 10 to 12 minutes. This may vary based on your air fryer. Serve immediately with your favorite dipping sauce.
