01 - Wash, peel (optional), and cut the potatoes into 1/4-inch thick fries using a sharp knife and cutting board.
02 - Submerge the cut potatoes in cold water for 20–30 minutes to remove excess starch for crispier results.
03 - Drain the water and pat the fries completely dry with a clean towel or paper towels to ensure proper crisping.
04 - Place fries in a large bowl and toss with olive oil, sea salt, and black pepper until evenly coated.
05 - Preheat the air fryer to 380°F for 3 minutes before cooking.
06 - Spread the fries in a single layer in the air fryer basket, cooking in batches if necessary to avoid overcrowding.
07 - Cook for 15–20 minutes, shaking the basket halfway through cooking time, until fries are golden brown and crispy.
08 - Immediately sprinkle with extra sea salt while hot and serve with your favorite dipping sauces.
