Make crunchy, healthy sweet potato chips at home using this straightforward baking recipe. These oven-baked crisps are a great alternative to store-bought chips and work well as a snack or side dish.

Ingredients

Scale
  • 2 large sweet potatoes
  • 2 tablespoons olive oil
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon paprika (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper.
  2. Wash and dry the sweet potatoes thoroughly. You do not need to peel them for this recipe.
  3. Slice the sweet potatoes very thinly, aiming for a uniform thickness of about 1/16 inch. A mandoline slicer works best for consistent results.
  4. Place the sweet potato slices in a large bowl. Drizzle with olive oil and toss until all slices are lightly coated.
  5. In a small bowl, mix the salt, pepper, and paprika. Sprinkle this seasoning mix over the oiled slices and toss again to coat evenly.
  6. Arrange the slices in a single layer on the prepared baking sheets. Do not overlap the chips; use two sheets if necessary to avoid crowding, which causes steaming instead of crisping.
  7. Bake for 15 minutes. Carefully flip each chip.
  8. Return the sheets to the oven and bake for another 10 to 15 minutes, watching closely during the last few minutes to prevent burning. The chips are done when they are golden brown and crisp.
  9. Remove from the oven and let the chips cool completely on the baking sheets. They will crisp up further as they cool.

Notes

  • For maximum crispiness, ensure your sweet potato slices are as thin and uniform as possible.
  • If using an air fryer, cook the seasoned slices in a single layer at 375°F (190°C) for 10 to 15 minutes, shaking the basket every 5 minutes until crisp.
  • If you prefer a sweeter chip, reduce the salt and add 1 teaspoon of brown sugar to the seasoning mix.
