01 - Peel the potatoes (optional for a rustic look), then cut them into 1/4-inch thick fries.
02 - Soak the cut potatoes in a large bowl of cold water for at least 30 minutes to remove excess starch.
03 - Drain and thoroughly pat the fries dry with clean kitchen towels.
04 - In a large bowl, toss the fries with olive oil, sea salt, and any optional seasonings.
05 - Preheat the air fryer to 380°F for 3 minutes.
06 - Arrange the fries in a single layer in the air fryer basket. Cook in batches if necessary to avoid overcrowding.
07 - Air fry for 18-22 minutes, shaking the basket halfway through, until fries are golden and crispy.
08 - Taste and sprinkle with extra sea salt if desired. Serve hot.
