Preparing Sweet Potatoes for Dehydration
Before dehydrating sweet potatoes, it’s essential to prepare them properly. Here’s a step-by-step guide:
Washing and Peeling
- Wash the sweet potatoes thoroughly to remove any dirt or debris.
- Peel the sweet potatoes using a vegetable peeler or a sharp knife.
Slicing or Dicing
- Slice or dice the sweet potatoes into uniform pieces, depending on your desired texture and recipe.
- For crispy sweet potato snacks, slice the sweet potatoes into thin rounds or strips.
- For rehydrating in recipes, dice the sweet potatoes into small cubes.
Blanching (Optional)
- Blanching sweet potatoes can help inactivate enzymes that can cause spoilage and improve their texture.
- To blanch sweet potatoes, submerge them in boiling water for 2-3 minutes, then immediately transfer them to an ice bath to stop the cooking process.
Dehydrating Sweet Potatoes in a Food Dehydrator
Once your sweet potatoes are prepared, it’s time to dehydrate them. Here’s a step-by-step guide:
Temperature Settings
- Set your food dehydrator to 135°F (57°C) for 6-8 hours or 145°F (63°C) for 4-6 hours.

Dehydrator Trays
- Place the sweet potato slices or cubes in a single layer on the dehydrator trays.
- Make sure not to overlap the sweet potatoes, as this can cause uneven dehydration.
Dehydration Time
- Dehydration time will vary depending on the temperature setting, sweet potato thickness, and desired texture.
- Check the sweet potatoes after 4-6 hours and continue dehydrating until they reach your desired texture.
Storage and Rehydration Tips
Once your sweet potatoes are dehydrated, it’s essential to store them properly to maintain their texture and nutrients. Here are some storage and rehydration tips:
Airtight Containers
- Store dehydrated sweet potatoes in airtight containers, such as glass jars or plastic bags.
- Remove as much air as possible from the container to prevent moisture from entering.
Rehydration Methods
- To rehydrate dehydrated sweet potatoes, soak them in water or broth for 30 minutes to an hour.
- You can also rehydrate dehydrated sweet potatoes by adding them to soups, stews, or casseroles.
Tips and Variations
Here are some tips and variations to enhance your dehydrated sweet potato experience:
Seasonings and Spices
- Add seasonings and spices to your dehydrated sweet potatoes for extra flavor.
- Try using herbs like thyme, rosemary, or oregano, or spices like paprika, garlic powder, or chili powder.
Combining with Other Ingredients

What are the benefits of dehydrating sweet potatoes?
Dehydrating sweet potatoes is a great way to preserve them for long-term storage and enjoy them year-round. Dehydrated sweet potatoes can be stored for up to a year, making them a convenient option for emergency food supplies, camping trips, or backpacking adventures. Additionally, dehydrating sweet potatoes helps retain their nutritional value, including vitamins A and C, potassium, and fiber.
Dehydrated sweet potatoes are also lightweight and compact, making them easy to transport and store. They can be rehydrated quickly by soaking them in water or broth, making them a great option for meals on-the-go. Furthermore, dehydrating sweet potatoes allows for a wide range of culinary uses, from making sweet potato powder to adding them to soups, stews, and casseroles.
What equipment do I need to dehydrate sweet potatoes?
To dehydrate sweet potatoes, you will need a few basic pieces of equipment. A food dehydrator is the most common and efficient way to dehydrate sweet potatoes. You can choose from a variety of models, ranging from small, compact units to large, commercial-grade dehydrators. If you don’t have a food dehydrator, you can also use your oven on the lowest temperature setting or a sun oven.
In addition to a dehydrator or oven, you will also need some basic kitchen tools, such as a peeler, slicer, and cutting board. A mandoline or sharp knife is recommended for slicing the sweet potatoes thinly and evenly. You may also want to invest in some dehydrator sheets or parchment paper to line your dehydrator trays and prevent sticking.
How do I prepare sweet potatoes for dehydrating?
Before dehydrating sweet potatoes, it’s essential to wash and peel them thoroughly. Use a vegetable brush to scrub away any dirt or debris, and then peel the sweet potatoes using a vegetable peeler. Next, slice the sweet potatoes into thin, even rounds or strips. You can use a mandoline or sharp knife to get uniform slices.
It’s also important to blanch the sweet potato slices in boiling water or steam for 2-3 minutes to inactivate the enzymes that can cause spoilage. After blanching, immediately plunge the slices into an ice bath to stop the cooking process. This step helps preserve the color, texture, and nutritional value of the sweet potatoes.
What temperature and time settings should I use for dehydrating sweet potatoes?
The ideal temperature and time settings for dehydrating sweet potatoes depend on the thickness of the slices and the desired level of dryness. As a general guideline, set your dehydrator to 135°F (57°C) for 6-8 hours for thin slices or 8-10 hours for thicker slices. If using your oven, set the temperature to its lowest setting (usually around 150°F or 65°C) and dehydrate for 6-8 hours.
It’s essential to monitor the sweet potatoes’ dryness and texture during the dehydration process. Check on them every hour or two to ensure they are not overdrying or underdrying. You can also use a food thermometer to check the internal temperature of the sweet potatoes, which should reach 160°F (71°C) for optimal dryness.
How do I store dehydrated sweet potatoes?
Proper storage is crucial to maintaining the quality and shelf life of dehydrated sweet potatoes. Store them in airtight containers, such as glass jars or plastic containers, to keep moisture and air out. You can also use vacuum-sealed bags or Mylar bags for longer-term storage.
When storing dehydrated sweet potatoes, keep them in a cool, dry place, such as a pantry or cupboard. Avoid storing them in direct sunlight, near a heat source, or in humid environments. If you plan to store them for an extended period, consider adding a desiccant packet or oxygen absorber to the container to maintain a dry environment.
Can I dehydrate sweet potatoes in the sun?
Yes, you can dehydrate sweet potatoes in the sun, but it requires careful planning and attention to detail. Sun drying is a low-cost and energy-efficient method, but it can be slower and more labor-intensive than using a dehydrator or oven. To sun dry sweet potatoes, slice them thinly and place them on wire racks or trays, making sure they don’t overlap.
Cover the sweet potatoes with cheesecloth or a mesh screen to keep insects away and allow air to circulate. Place the racks in direct sunlight, ideally in a warm, dry location with good air circulation. Bring the sweet potatoes inside at night to prevent moisture from accumulating. Sun drying can take several days to a week, depending on the weather conditions and the desired level of dryness.
How do I rehydrate dehydrated sweet potatoes?
Rehydrating dehydrated sweet potatoes is a simple process that requires soaking them in water or broth. The ratio of water to sweet potatoes is usually 1:1, but you can adjust it to your desired consistency. Soak the sweet potatoes in water or broth for 30 minutes to an hour, or until they reach your desired level of rehydration.
You can also rehydrate dehydrated sweet potatoes by cooking them in a pot of boiling water or broth. Simply add the sweet potatoes to the pot and cook until they’re tender, usually 10-15 minutes. Alternatively, you can add dehydrated sweet potatoes directly to soups, stews, or casseroles, where they’ll rehydrate during cooking.
