how to dehydrate sweet potatoes in a food dehydrator


Sweet potatoes are not only delicious but also incredibly nutritious. They are packed with vitamins, minerals, and fiber, making them a healthy addition to any diet. One of the best ways to preserve sweet potatoes and enjoy them for longer periods is by dehydrating them. Dehydrating sweet potatoes removes their moisture content, thereby extending their shelf life while maintaining their flavor and nutritional value. In this comprehensive guide, we will walk you through the process of dehydrating sweet potatoes in a food dehydrator, providing you with all the necessary steps and tips to achieve perfectly dehydrated sweet potatoes every time.

1. Choosing the Right Sweet Potatoes:

When it comes to dehydrating sweet potatoes, it is crucial to start with the right ones. Look for sweet potatoes that are firm, with no signs of decay or soft spots. Select potatoes that are uniform in size to ensure even drying. Additionally, opt for organic sweet potatoes if possible, as they are free from pesticides and chemicals.

2. Preparing the Sweet Potatoes:

Before you begin dehydrating, it's essential to properly prepare the sweet potatoes. Wash them thoroughly under cold running water to remove any dirt or debris. Pat them dry with a clean kitchen towel or paper towels. Next, peel the sweet potatoes using a vegetable peeler or a knife. Once peeled, rinse them again to remove any remaining dirt.

3. Slicing the Sweet Potatoes:

The next step is to slice the sweet potatoes into uniform, thin slices. You can do this manually using a knife or use a mandoline slicer for faster, more consistent results. Aim for slices that are approximately ¼ inch thick. Uniform slices ensure even drying and prevent some pieces from being over- or under-dehydrated.

4. Blanching (Optional):

While not necessary, blanching sweet potatoes before dehydrating can help preserve their color and texture. To blanch the slices, bring a large pot of water to a boil and add the sweet potato slices. Allow them to simmer for about 2 minutes, then remove them and immediately plunge them into an ice bath for another 2 minutes. Finally, drain the slices and pat them dry before placing them in the dehydrator.

5. Arranging the Sweet Potato Slices in the Dehydrator:

Once your sweet potato slices are ready, it's time to arrange them in your food dehydrator. Lay the slices in a single layer on the dehydrator trays, ensuring they do not overlap. Leaving some space between the slices allows for better airflow and promotes even drying. If your dehydrator has an adjustable temperature setting, set it to around 125°F (52°C). This temperature is optimal for dehydrating sweet potatoes, as higher temperatures may cause the potatoes to become too crispy or burnt.

6. Dehydrating the Sweet Potatoes:

Place the loaded trays into the food dehydrator and turn it on. The dehydrating process typically takes anywhere between 6 to 12 hours, depending on the thickness of the slices and the moisture content of the sweet potatoes. It's essential to periodically check the slices during the drying process to monitor their progress. Thick slices may require flipping to ensure consistent drying on both sides. Once dehydrated, the sweet potato slices should be firm, crisp, and brittle.

7. Testing for Doneness:

To ensure your sweet potatoes are adequately dehydrated, conduct a simple test. Take a slice out of the dehydrator and allow it to cool for a few minutes. Then, squeeze it between your fingers. If the slice breaks easily and crumbles, it is dried correctly. However, if it bends or feels flexible, it needs more time in the dehydrator. Properly dehydrated sweet potatoes have a moisture content of around 10% to 15%.

8. Cooling and Storing:

After dehydrating, allow the sweet potato slices to cool completely before storing them. This prevents condensation from forming inside the storage container and ensures crispy slices. Once cooled, transfer the slices into airtight containers such as glass jars or resealable bags. Store them in a cool, dark cupboard away from moisture, heat, and light. Properly dehydrated sweet potatoes will last for several months when stored correctly.

9. Rehydrating and Using Dehydrated Sweet Potatoes:

Dehydrated sweet potatoes have a long shelf life and can be a versatile ingredient in various recipes. To rehydrate them, simply soak the slices in warm water for about 15-20 minutes until they become plump and regain some of their original texture. You can then use the rehydrated sweet potatoes in soups, stews, casseroles, or even blend them into powder to make sweet potato flour.

In conclusion, dehydrating sweet potatoes in a food dehydrator is a fantastic way to preserve this nutritious root vegetable. With the right preparation, slicing, and dehydrating techniques, you can enjoy sweet potatoes throughout the year. So why not give it a try? Dehydrate your sweet potatoes today and savor their natural sweetness and health benefits whenever desired.
