How to Freeze-Dry Sweet Potatoes

Sweet potatoes pack in vitamin A, vitamin C, manganese, copper, potassium, dietary fiber, and several B vitamins — and freeze-drying them turns a seasonal vegetable into something you can keep on hand year-round, whether whole slices or ground into a versatile powder.

How to Prepare Them

Slice sweet potatoes about 1 inch thick and arrange them in a single layer on the freeze-drying trays. Once dried, store them in an airtight container until you're ready to use them.

Ways to Use Freeze-Dried Sweet Potatoes

• Mashed sweet potatoes: Grind the dried slices into a powder, then mix with hot water, butter, and a dash of cinnamon for a quick mashed side.
• Smoothie boost: Add the powder to smoothies for extra fiber and nutrients without changing the texture much.
• Low-calorie snack: Eat dried slices plain as a high-fiber, portion-friendly snack between meals.
• Casseroles and stews: Add diced freeze-dried sweet potato to dishes built around lentils, curry powder, sea salt, and rice for a heartier, more filling meal.
• Chips or sweet treats: Slice thin, season with salt for savory chips or cinnamon and sugar for a sweeter treat.
