Remove the skin of potatoes using a peeler. You can roughly scrub it with a kitchen towel if its thin instead of peeling.
Using a sharp knife or mandoline slicer, thinly slice the potatoes into rounds. Aim for slices that are about ⅛ inch thick for optimal crispiness.
Transfer the potato slices to a large bowl filled with ice-cold water. Let them sit in cold water for 10 – 15 minutes. This step helps in removing excess starch from the potato slices.
Arrange the potato slices on a clean, kitchen cloth in a single layer without overlapping each other. Cover them with another kitchen towel. Pat dry, making sure to remove all the water. This takes approximately 20 minutes. You can place them covered under a fan also.
Place the potato slices on a large sheet and drizzle with olive oil. Toss gently to coat each slice evenly. Season the potato slices with salt, pepper, and any additional seasonings of your choice.
Preheat your air fryer to 360°F (180°C). Spray the basket with oil.
Arrange the seasoned potato slices in a single layer in the air fryer basket, making sure not to overcrowd them. You may need to cook the chips in batches depending on the size of your air fryer.
Cook the potato chips in the air fryer for 10-12 minutes, flipping halfway through, until golden brown and crispy. Keep a close eye on them towards the end to prevent burning.
Once the chips are done cooking, transfer them to a colander or a big bowl. Allow the chips to cool slightly before serving or storing.
