Wash and scrub the potatoes, then slice them very thinly (about 1/8 inch) using a mandolin or carefully with a sharp knife.
Place the slices in a large bowl and cover with cold water; soak for 30 minutes to remove excess starch.
Drain the potato slices and dry them thoroughly with a kitchen towel or paper towels.
Preheat the air fryer to 370°F (about 188°C).
Toss the dry potato slices with 2 tablespoons olive oil and season with salt, pepper, and smoked paprika to taste.
Arrange the slices in a single layer in the air fryer basket (cook in batches if needed to avoid overcrowding).
Air fry for 10 minutes, then toss or shake the basket to move the slices so they cook evenly.
Continue cooking for an additional 15–17 minutes, checking and tossing every few minutes; remove any chips that are browned to prevent burning and keep cooking until all are crisp.
