These 3-ingredient sweet potato chips are oven-baked and extra crispy. The secret is thinly slicing paired with cooking on a wire baking rack for full air flow.
Preheat the oven to 300°F. Prepare a baking sheet by fitting it with a large cooling rack.
Using a sharp knife, cut the sweet potatoes into thin, even slices, no more than ⅛-inch thick. Transfer the sweet potato slices to a large bowl and toss with the oil and salt. Arrange in a single layer on the cooling rack (some slight overlap is okay).
Bake for 30–40 minutes, flipping every 10 minutes or until the chips are curling and browning around the edges. Let cool completely on the cooling rack, then store in an airtight container.
Notes
Storage: Store cooled chips in an airtight container for 4–5 days.
