Loading the Dehydrator
- Load the sliced or diced sweet potatoes onto the dehydrator trays in a single layer, making sure not to overlap them.
- Leave some space between each sweet potato slice or cube to allow for air circulation.
Dehydrating Time and Temperature
- Dehydrate the sweet potatoes at 135°F (57°C) for 6-8 hours or until they reach your desired level of dryness.
- Check the sweet potatoes every hour to rotate the trays and ensure even drying.
Storage and Rehydration Tips
Once the sweet potatoes are dehydrated, it’s essential to store them properly to maintain their nutritional value and texture. Here are some storage and rehydration tips:
Storage Containers

What are the benefits of dehydrating sweet potatoes?
Dehydrating sweet potatoes is a great way to preserve their nutritional value and make them last longer. When sweet potatoes are dehydrated, the water content is removed, which prevents the growth of bacteria and other microorganisms that can cause spoilage. This process also helps to concentrate the nutrients, making dehydrated sweet potatoes a nutrient-dense snack.
Dehydrated sweet potatoes are also versatile and can be used in a variety of dishes, such as soups, stews, and salads. They can also be rehydrated and used as a side dish or added to recipes. Additionally, dehydrating sweet potatoes is a cost-effective way to enjoy them year-round, as they can be stored for up to a year when properly dried and stored.
What equipment do I need to dehydrate sweet potatoes?
To dehydrate sweet potatoes, you will need a dehydrator, which is a specialized appliance designed to remove the water content from foods. There are many different types of dehydrators available, ranging from small, compact models to large, commercial-grade machines. When choosing a dehydrator, consider the size and features that you need, such as temperature control and multiple trays.
In addition to a dehydrator, you will also need some basic kitchen tools, such as a peeler, a knife, and a cutting board. You may also want to invest in a mandoline or food slicer to help you slice the sweet potatoes thinly and evenly. This will help to ensure that they dry evenly and quickly.
How do I prepare sweet potatoes for dehydrating?
To prepare sweet potatoes for dehydrating, start by washing them thoroughly and peeling them using a vegetable peeler. Next, slice the sweet potatoes into thin rounds or strips, depending on your desired texture and use. You can also dice or chop the sweet potatoes into smaller pieces if you prefer.
It’s also a good idea to blanch the sweet potatoes in boiling water for 2-3 minutes to inactivate the enzymes that can cause them to turn brown or develop off-flavors during the dehydration process. After blanching, immediately submerge the sweet potatoes in an ice bath to stop the cooking process.
What temperature and time should I use to dehydrate sweet potatoes?
The ideal temperature and time for dehydrating sweet potatoes will depend on the type of dehydrator you are using and the desired level of dryness. Generally, it’s best to dehydrate sweet potatoes at a temperature of 135-140°F (57-60°C) for 6-8 hours. This will help to preserve the nutrients and flavor of the sweet potatoes.
However, if you prefer a crisper texture, you can dehydrate the sweet potatoes at a higher temperature of 150-155°F (65-68°C) for 4-6 hours. It’s also important to check on the sweet potatoes periodically to ensure that they are not overdrying or developing off-flavors.
How do I store dehydrated sweet potatoes?
To store dehydrated sweet potatoes, place them in an airtight container, such as a glass jar or plastic bag. Make sure to remove as much air as possible from the container to prevent moisture from entering and causing the sweet potatoes to become stale or develop off-flavors.
Store the container in a cool, dry place, such as a pantry or cupboard. Dehydrated sweet potatoes can be stored for up to a year when properly dried and stored. You can also freeze them for longer storage, but be sure to use airtight containers or freezer bags to prevent freezer burn.
Can I dehydrate sweet potatoes in the oven?
While it’s possible to dehydrate sweet potatoes in the oven, it’s not the most recommended method. Ovens can be unpredictable and may not provide the consistent temperature and air circulation needed for even dehydration. Additionally, ovens can be energy-intensive and may not be as cost-effective as using a dehydrator.
However, if you don’t have a dehydrator, you can try dehydrating sweet potatoes in the oven on the lowest temperature setting (usually around 150-200°F or 65-90°C). Place the sweet potatoes in a single layer on a baking sheet and check on them periodically to ensure that they are not overdrying or developing off-flavors.
Are dehydrated sweet potatoes healthy?
Dehydrated sweet potatoes can be a healthy snack option, depending on how they are prepared and stored. Sweet potatoes are rich in vitamins A and C, potassium, and fiber, making them a nutrient-dense food. When dehydrated, these nutrients are concentrated, making dehydrated sweet potatoes a healthy choice.
However, it’s also important to consider the added ingredients and seasonings that may be used during the dehydration process. Some dehydrated sweet potato products may contain added sugars, salt, or preservatives, which can negate the health benefits of the sweet potatoes. When making your own dehydrated sweet potatoes, be sure to use minimal added ingredients and seasonings to preserve the natural nutrients and flavor.
