Preheat air fryer to 400 F according to manufacturer instructions. (Mine was 400 F for 5 minutes) Cosori 5.8 quart
Wash and dry the potatoes. Cut them in ¼ inch wide strips and then each strip into ¼ inch wide strips.
In a large bowl soak the potato strips in room temperature water for 15-30 minutes. (I haven’t seen much of a difference in the final result when soaking for 30 minutes or 2 hours!)
Wash the potatoes again and dry them properly.
In a large bowl combine potato strips, oil, and spices (or you can use a zip lock bag for this). Massage the potatoes to ensure they are coated entirely. However you can add more seasonings once fries are cooked.
Once the air fryer is preheated, transfer the fries into the basket and air fry for 20-25 minutes, shaking the basket halfway through a couple of times to ensure even frying.
The fries should be crispy and cooked through. If by this time fries are not crispy, fry for more minutes. If fries are cut too thin or the ends are too narrow they will get charred rather quickly. The end result: the exterior of fries are slightly browned and crispy, softer potato texture on the inside.
Transfer the hot fries into a shallow bowl, add salt, parmesan and toss/shake well. You can add more onion powder here as well. Enjoy with dipping sauces.
