For extra crispy fries, soak the cut potatoes in cold water for 30 minutes before seasoning and pat dry thoroughly. Use a high smoke point oil like corn oil for extra crispiness. Flip fries halfway through baking for even browning. Broil for 2-3 minutes at the end for extra crispiness but watch carefully to avoid burning. Leftovers can be stored in an airtight container for up to 3 days and reheated in the oven at 400°F for about 10 minutes.
