Instructions

Preheat the oven to 300°F. Line two baking sheets with parchment paper.
Peel the purple sweet potatoes and slice them as thin and evenly as possible using a mandoline, about 1/16 inch thick. Consistent thickness is key here. Thick slices won't crisp up and thin ones will burn.
In a large bowl, toss the slices with 1 tablespoon melted coconut oil until every slice is lightly coated. Arrange in a single layer on the prepared baking sheets with space between each slice. Don't overlap them. Sprinkle with salt.
Bake for 35 to 45 minutes, flipping the slices once halfway through. Start checking around the 25-minute mark. The chips won't all finish at the same time, so remove any that are crispy at the edges and curling up while the rest continue baking.
Let the chips cool on the baking sheets for 5 to 10 minutes before serving. They'll feel slightly soft when they first come out of the oven but will crisp up as they cool.

Notes

Oil: Coconut oil, avocado oil, or olive oil all work here. Use just enough to lightly coat the slices. Too much oil and the chips won't crisp up properly.
Mandoline: A mandoline gives you thin, even slices, which is the difference between a batch of crispy chips and a batch where half are burnt and half are soft. Always use the hand guard or a cut-resistant glove. Purple sweet potatoes are dense and require more pressure on the blade.
Storage: These chips are best eaten the same day. They lose their crispness as they sit. If they soften overnight, spread them on a baking sheet and bake at 300°F for 5 to 10 minutes to re-crisp.
