Preheat air fryer to 380F for 5 minutes. Rinse the sweet potatoes. Use a mandolin slicer to slice sweet potato to 1/8 inch thick. Put on paper towels and wrap up to absorb all the water on the outside.
Place in a bowl then pour 1 Tablespoon of olive oil over the slices, then sprinkle in the salt and black pepper (o rany other seasoning you’re using), give the ingredients a good stir to try to coat the slices as best as possible.
Arrange sweet potato slice into the air fryer basket, do only one single layer and don’t let them overlap onto each other.
Set temperature to 380F and time to 6 minutes. At the 3 minute mark make sure to check on them and if the chips have moved rearrange them. Allow to cook remaining time. Next flip the chips over and cook them for 1 more minute.
After the minute is up the chips should be crisp and a bit browned. If your chips don’t look like that you can cook for another minute at a time until they do. Once finished allow to cool on a wire rack to crisp up even further. Enjoy as a healthy snack or side dish to a sandwich.
* Please note that every air fryer is different so it’s important to keep an eye on your chips and check them throughout the cooking process to avoid burning.
