Preparing the Sweet Potatoes

A sharp knife and a vegetable scrubber are visible, emphasizing the importance of cleanliness and precision in creating evenly sliced dehydrated sweet potatoes.
  1. Naturally, the very first thing that you would need to do is to wash the sweet potatoes. It is advisable to use water and a vegetable scrubber in order to remove the dirt from its skin. Before putting it in the dehydrator, pat it dry with a clean towel. Also, avoid unnecessary touches to lessen the transfer of oils from our skin to the sweet potato.
  2. After the sweet potatoes are cleaned, prepare your sharp knife to cut it into thin slices. You may also use a mandolin to ensure that each slice is as thick as the others, which means they will dehydrate at the same time. If you plan to bake sweet potatoes before dehydrating them, preheat oven before placing the sweet potatoes on a baking tray lined with parchment or a silicone mat. Arrange the sweet potato slices in a single layer on the baking tray for even drying.
  3. Steam or blanch the sweet potatoes until they are tender when poked using a fork. The color should turn brighter than it was before. If you are making shredded sweet potatoes, then there is no need to steam or blanch them. You can also choose to soak it in a bowl full of room temperature water. Cooked sweet potatoes can be used to make sweet potato bark or pudding; for these, you can mash the cooked sweet potatoes to achieve a smooth consistency.
  4. Dry each piece of sliced sweet potatoes using a clean paper towel. Make sure that they are completely dry before you put them in the food dehydrator.
  5. In this step, you can opt to drizzle a small amount of olive oil or coconut oil onto the sweet potatoes. This extra step will ensure crunchier chips. You can also add seasoning by adding spices and herbs, depending on what you want, of course. You can try cinnamon, sea salt, black pepper, cayenne paper, rosemary or thyme, smoked paprika, or powdered onion.

Do not add butter or fats to the sweet potatoes before dehydrating, as this can affect the texture and storage.

Dehydrating Process

  1. Using the dehydrator trays, lay out each piece of the sweet potato slices, making sure that they are only one layer thick and that there is no overlapping. This is to ensure that every slice is going to get evenly dried just like the rest of the batch.
  2. Before stacking the food trays inside, allow the dehydrator to warm up to the desired temperature setting. In this case, set the temperature level at around 140 degrees Fahrenheit.
  3. Sweet potatoes are fairly easy as compared to other tasks. If you want to do it quickly, set the timer for 12 hours. You can add more time until your desired crispiness is achieved. For a slower process, dehydrate it for about 20 to 24 hours. Always remember to check on it from time to time to ensure that they do not get overcooked. Note: Drying times may vary depending on slice thickness, humidity, and personal preference.

Tip: For best results, adjust the thickness of your sweet potato slices or rearrange the trays during dehydration to promote even drying.

  1. Once your desired crispiness is already achieved, allow the sweet potato chips a couple of minutes to cool down to room temperature. Test the sweet potatoes for doneness by pressing a piece—if it feels soft or leaves an indentation, it needs more time in the dehydrator. The sweet potatoes should be dry and brittle, not soft or damp, before storing. After which, it can now be stored inside a mason jar, an airtight re-sealable bag, or your favorite container. If you did not add any oil, this batch could last up to 12 months.

Storing Dried Sweet Potatoes

Once your dried sweet potatoes have finished dehydrating, it’s important to store them properly to maintain their flavor, texture, and nutritional benefits. First, allow the dried sweet potatoes to cool completely—this step helps prevent condensation, which can lead to spoilage. Transfer the cooled sweet potatoes into an airtight container, such as a glass jar with a tight-fitting lid or a sturdy plastic container with a secure seal.

Store your container in a cool, dark, and dry place, like a pantry or cupboard, to protect the dried sweet potatoes from heat, light, and moisture. Avoid placing them near stoves, windows, or other heat sources. When stored correctly, dried sweet potatoes can retain their delicious flavor and satisfying texture for up to two years, making them a convenient and long-lasting addition to your pantry.


Rehydrating Sweet Potatoes

Bringing dried sweet potatoes back to life is easy and only takes a few simple steps. To rehydrate, place your dried sweet potatoes in a bowl and pour hot water or boiling water over them. The amount of water you use will depend on your recipe and the thickness of your sweet potato pieces, but a good starting point is 1/4 to 1/2 cup of dried sweet potatoes per serving, with about 3/4 cup of hot water.

Cover the bowl and let the sweet potatoes soak—shredded or leather pieces will soften in about 10 to 20 minutes, while thicker slices or diced potatoes may need up to 40 minutes. Once rehydrated, you can cook or heat the sweet potatoes as you would fresh ones, making them perfect for mashed sweet potatoes, soups, stews, or any recipe that calls for tender, flavorful potatoes.


Common Mistakes to Avoid

When dehydrating sweet potatoes, a few common mistakes can impact the final result. One frequent error is skipping the blanching or cooking step before dehydration, which can cause the dried sweet potatoes to lose their vibrant color, flavor, and appealing texture. Another pitfall is not allowing the dried sweet potatoes to cool completely before storing them—trapping residual heat can create moisture inside the airtight container, leading to mold and spoilage.

It’s also important to avoid using excessively high temperatures or dehydrating for too long, as this can make your sweet potatoes overly brittle or even burnt, diminishing their flavor and texture. Always store your dried sweet potatoes in an airtight container to preserve their quality and extend their shelf life. By steering clear of these mistakes, you’ll enjoy delicious, long-lasting dried sweet potatoes every time.


Troubleshooting Dehydration Issues

If you run into problems while dehydrating sweet potatoes, don’t worry—most issues are easy to fix with a few adjustments. If your dried sweet potatoes turn out too dry or brittle, it’s likely they were dehydrated for too long or at too high a temperature. Next time, try reducing the dehydration time or lowering the temperature to achieve a softer, more pleasant texture.

On the other hand, if your dried sweet potatoes are still moist or sticky after dehydration, they may need more time or a slightly higher temperature to reach the ideal dryness. If you notice any signs of mold or moisture inside your storage container, double-check that your dried sweet potatoes were cooled completely before storing and that your container is truly airtight. With these troubleshooting tips, you’ll be able to perfect your batch and enjoy high-quality dried sweet potatoes every time.
