Start by washing the potatoes thoroughly to remove any dirt or debris. With a sharp knife or a peeler, carefully remove the skin from the potatoes.

Use a mandoline slicer or a sharp knife, slice the potatoes into thin, uniform rounds.. Thinner slices will result in crispier chips, so try to keep them consistent in size about 1/8 inch thick.

Place the potato slices in a bowl of cold water and let them soak for about 30 minutes. This step helps to remove excess starch from the potatoes, which will result in crispier chips.

After soaking, drain the potato slices and pat them dry with a clean kitchen towel or paper towels. Make sure to remove as much moisture as possible to achieve crispy chips.

In a large bowl, toss the dried potato slices with vegetable oil, sea salt, and black pepper (if using). Ensure that the slices are evenly coated with the seasoning.

Preheat your air fryer to 380°F for about 3-5 minutes.

Once the air fryer is preheated, arrange the seasoned potato slices in a thin layer in the air fryer basket. Cook the potato chips at 380°F for 12-15 minutes, stir them halfway through the cooking time. Keep an eye on them towards the end to prevent burning, as cooking times may vary depending on the thickness of the slices and the efficiency of your air fryer.

The chips are done when they are golden brown and crispy.

Once the potato chips are done, transfer them to a serving bowl and let them cool slightly before serving. Enjoy them on their own as a tasty snack or pair them with your favorite dip or sauce.
