If you’ve landed here looking for dog treats, you want our sweet potato dog treats guide instead — that’s a plain, single-ingredient dry at a different target texture. This article covers dehydrating sweet potatoes for people: pantry storage, backpacking meals, soups, and snacking, prepped and pretreated for human eating.
Not the Same as Dog Treats
Dog treats are typically sliced thick and dried long and slow into a chewy jerky-like treat with nothing else added. This guide covers thinner slices, cubes, and shreds pretreated specifically to avoid the raw, “uncooked” taste that untreated sweet potato retains after drying — a flavor issue that doesn’t matter much to a dog but matters quite a bit if you’re planning to eat the result yourself.
Blanching vs. Baking
Sweet potatoes need a pretreatment step before drying, or the finished product retains an unpleasant raw, starchy taste even after full rehydration. Two methods are both well established:
- Blanching — steam or boil for 2-3 minutes (slices/cubes) or until nearly tender, then drain. Faster and simpler.
- Baking — bake whole or cut sweet potatoes at 350°F for about 20 minutes before dehydrating. Several dehydrating guides note this gives noticeably better flavor and texture on rehydration compared to blanching, in direct side-by-side comparisons, though it takes more active oven time upfront.
If flavor is your top priority and you don’t mind an extra 20 minutes of oven time, baking is worth trying. If speed matters more, blanching is faster and still produces a perfectly usable result.
Peeling is optional and mostly a texture preference — the skin dries fine and adds fiber. Wash thoroughly either way, since sweet potato skin can carry more surface grit than a smooth-skinned vegetable.
Choosing a Cut
- Slices (1/8-1/4 inch) — best for snacking chips or scalloped-style dishes.
- Cubes (under 1/2 inch) — best for soups, stews, and rehydrating into meals; smaller pieces rehydrate faster and more evenly.
- Shreds — less common than the equivalent regular-potato hash brown, but works the same way for a sweet-potato hash.
Dehydrating Sweet Potatoes Step by Step
- Wash (and peel, if desired) sweet potatoes. Slice, cube, or shred to your chosen size.
- Pretreat: either blanch 2-3 minutes and drain, or bake at 350°F for about 20 minutes and cool before cutting further if needed.
- Arrange in a single layer on dehydrator trays, using a mesh liner for shreds so pieces don’t fall through as they shrink.
- Set dehydrator to 125°F. Dry 7-15 hours depending on cut — slices finish fastest, cubes take longest.
- Sweet potatoes are done when hard and brittle (for storage) or leathery (for near-term snacking), with no soft or damp spots.
- Cool completely before storing.
How to Tell They’re Done
For long-term storage, sweet potato pieces should be hard, brittle, and slightly translucent, snapping rather than bending. Split a thicker piece in half to double-check the center — a piece that’s dry on the surface but still soft or cool inside needs more time. If you’re planning to eat a batch within a few weeks rather than storing it long-term, a leathery, chewy texture is fine and doesn’t need to go all the way to fully brittle.
Storage and Rehydrating
Store cooled, fully dried sweet potatoes in an airtight container in a cool, dark place; properly dried and stored, they commonly keep for up to a year at good quality. To rehydrate, soak in warm water for about 30 minutes until they’ve plumped back up, or add directly to soups and stews with enough extra liquid to account for absorption during cooking.
Common Mistakes to Avoid
Skipping the pretreatment step entirely is the single most common misstep — the resulting raw, starchy aftertaste is much harder to notice in a quick taste test right after drying than it is once the pieces are fully rehydrated into a dish weeks later. Don’t skip blanching or baking based on an early taste test of the fresh-dried chip.
The second is cutting cubes larger than about 1/2 inch. Sweet potato flesh is dense, and oversized cubes both take considerably longer to dry and rehydrate less evenly later. Keep cubes small and consistent, even if it means a bit more knife time upfront.
Frequently Asked Questions
You can, but the finished product will retain a raw, starchy taste even after full drying and rehydration. It’s not a food-safety requirement, but it makes a real difference in how the result tastes.
Several dehydrating guides that tested both side by side found baking gave better flavor and texture on rehydration. Blanching is faster, though, and still produces a good result — it’s a genuine tradeoff rather than one method being simply wrong.
Not quite like store-bought chips, which are usually fried or baked at high heat. Dehydrated slices come out more leathery-to-crisp depending on thickness, closer to a chewy chip than a crunchy one — still good, just a different texture.
