Step 1

Preheat oven to 275°F.

Step 2

Wash sweet potatoes and slice thinly with a mandoline slicer or sharp knife. No need to peel the potatoes.

Step 3

Place potato slices in a bowl with oil and sea salt. Start with 1/2 Tablespoon of oil and add more if needed. You want the sweet potato slices lightly coated. Toss to combine until all slices are lightly coated with oil.

Step 4

Set slices in a single layer on a baking sheet and bake for 40-50 minutes, flipping the chips every 15 minutes and watching them carefully as some might start to brown faster than others.

Step 5

Chips are done when they're golden in color and crisp.

Step 6

These chips are best eaten right away, but they can be stored in an airtight container for 1-2 days. If they get soft, you can pop them back in the oven to crisp up again before serving.
