How to Dehydrate Sweet Potatoes

Sweet potatoes are a nutritious form of carbohydrates. They are low in sodium, fat and cholesterol, but high in fiber, Vitamin A, Vitamin B6, Potassium and Manganese.[1] For a healthy alternative to potato chips, you can dehydrate sweet potatoes into chips using your oven or a dehydrator.

Steps

Dehydrating Sweet Potatoes in a Dehydrator

  1. Purchase a dehydrator. One sweet potato can fill up a small dehydrator; on the other hand, it may take two to four potatoes to fill a large dehydrator.

  2. Wash the skin of your sweet potato. You don’t need to peel it, unless desired, since the peel is filled with nutrients.

  3. Grab a sharp knife or a mandolin slicer. The mandolin slicer is ideal for even dehydration, because you can set it to slice the potatoes at the same width. Set your slicer to one-eighth inch (0.3cm).

  4. Press the top of the sweet potato to the mandolin slicer and move in a downward motion, slicing in one-eighth inch rounds until you reach the end of your potato. Use the vegetable holder to ensure you don’t cut your hands on the sharp mandolin.

  5. Soak the potatoes in a bowl of water for one hour. Change the water halfway through. This process will remove some of the starch from the potatoes and help them be crispier.

    • You can also blanche the sweet potato slices for two minutes in boiling water to make them bright and to preserve the nutrients.
  6. Set the sweet potato slices on a towel and pat them. They should be thoroughly dry.

  9. Set your dehydrator to 145 degrees Fahrenheit (63 Celsius). If your dehydrator is older, you may want to set it to 155 degrees (68 Celsius). Older models tend to run slightly cooler.
