How to Dehydrate Sweet Potatoes
Slice sweet potatoes evenly, blanch or steam briefly for storage (skip for chewy treats), and dry at 125 to 135F (52 to 57C) until brittle for storage, or leathery for chews, roughly 6 to 12+ hours.
Sweet potatoes dry two ways: brittle for pantry storage and rehydrating, or leathery for chewy snacks, including the popular homemade dog chews. Your goal decides the method.
Prep and (optional) blanch
Wash, peel if you like, and slice evenly. For storage, a brief blanch or steam sets colour and improves rehydration. For chewy treats, you can skip blanching and simply dry to leathery.
Temperature and time
Dry at 125–135F (52–57C). For storage, take slices to brittle (about 8–12+ hours); for chews, stop at pliable leathery (roughly 6–10 hours). Thickness changes timing a lot.
Store
Cool fully and store airtight. Brittle slices rehydrate for cooking, see how to rehydrate; leathery chews keep best refrigerated. See shelf life and the best dehydrators.
Frequently asked questions
Do I blanch sweet potatoes before dehydrating?
For long storage, a brief blanch or steam helps colour and rehydration. For chewy treats (including dog chews), many skip blanching and dry to leathery.
Are dehydrated sweet potatoes good dog treats?
Plain, dried sweet potato slices are a popular dog chew. Dry to a firm, leathery texture and check with your vet about your dog's diet.
