Equipment Needed for Dehydrating Sweet Potatoes in the Oven

Before you begin, gather the necessary tools and equipment:

• A sharp knife or mandoline slicer
• A cutting board
• Fresh, clean sweet potatoes
• An oven
• Baking sheets or oven trays
• Parchment paper or cooking spray

Step-by-Step Guide to Dehydrating Sweet Potatoes in the Oven

1. Preparation: Preheat your oven to its lowest setting, ideally around 175°F (79°C). Wash and trim any blemishes from the sweet potatoes. Then, cut the sweet potatoes into consistent-sized slices or dices, about 1/8-1/4 inch thick for slices or 1/4-1/2 inch for dices. You can use a knife or a mandoline slicer for more uniform slices.
2. Arrangement: Line your baking sheets with parchment paper or lightly spray them with cooking spray. Lay out the sweet potato slices or dices evenly on the lined baking sheets, ensuring they don’t overlap.
3. Dehydration: Place the baking sheets in the preheated oven and let the sweet potatoes dehydrate for several hours. The exact time will depend on the thickness of the slices and your oven’s temperature. Check the sweet potatoes periodically to ensure they reach your desired level of dryness.

How to Know When Sweet Potatoes are Properly Dehydrated?

Properly dehydrated sweet potatoes should be dry and hard. If you have dehydrated sweet potato shreds, they should be brittle when properly dried. Moreover, dehydrated sweet potatoes should have a consistent color throughout, without any dark or discolored spots.

Storing Dehydrated Sweet Potatoes and Their Shelf Life

Store dehydrated sweet potatoes in a clean, airtight container. For longer shelf life, vacuum sealing is recommended. Properly stored dehydrated sweet potatoes can last up to one year. However, some sources suggest that when stored in enameled cans or vacuum-sealed containers and kept in a cool, dark place, dehydrated sweet potatoes can last up to 20 years or even 25 years.

Creative Ways to Use Dehydrated Sweet Potatoes

Dehydrated sweet potatoes can be used in various creative ways in cooking and baking:

• Rehydrate and use in soups and stews: Add dehydrated sweet potatoes to boiling water and let them rehydrate for a few minutes.
• Sweet potato chips: Slice sweet potatoes thinly, toss them in coconut oil, sea salt, and cinnamon (optional), and dehydrate them to make sweet potato chips.
• Sweet potato flour: Grind dehydrated sweet potato slices into a fine powder using a high-speed blender or coffee grinder.
• Sweet potato puree: Rehydrate sweet potato powder with boiling water to create a puree that can be used in pies, biscuits, casseroles, or as a side dish.
• Backpacking meals: Dehydrated sweet potatoes are lightweight and can be added to backpacking meals like burrito bowls, pasta, or rice dishes.
• Sweet potato dog treats: Dehydrate sweet potato slices and use them as healthy, homemade dog treats.

In conclusion, dehydrating sweet potatoes in the oven is a simple and effective way to preserve them and concentrate their flavor and nutrients. With the right tools, preparation, and storage, you can enjoy dehydrated sweet potatoes in a variety of dishes or as a healthy snack. Happy dehydrating!
