Preheat the air fryer to 400°F (200°C)
Wash and scrub the potatoes, leaving the skins on. Slice each potato in half lengthwise, then cut each half into quarters. From there, cut the quarters into ½-inch wedges, usually three wedges per quarter, depending on the size of your potato. Each potato should yield around 12 wedges.
Transfer the potato wedges to a large bowl and cover with cold water. Swirl them around with your hand, then drain and refill the bowl. Repeat once or twice until the water is mostly clear.
After rinsing, turn the tap to hot and cover the potatoes with very hot water (boiling isn’t necessary). Let the wedges soak for 15 to 20 minutes to remove excess starch. Drain well and pat completely dry with paper towels.
Add the potatoes to a clean bowl. Drizzle with olive oil and sprinkle with salt and pepper. Toss until evenly coated.
Arrange the wedges in a single layer in the air fryer basket (some overlapping is ok). You may need to cook them in batches to avoid overcrowding.
Air fry for 15 to 20 minutes, shaking the basket halfway through, until golden and crispy on the edges.
Transfer to a serving plate and season with additional salt, to taste. Garnish with parsley, if desired. Serve immediately with your favorite dipping sauce.
