One cup of dried vegetables makes about two cups rehydrated, per Alabama Extension.

How to do it

  • Soak in cold water, bouillon or juice for one to two hours (Clemson). Refrigerate if soaking longer than two hours.
  • Simmer root, stem and seed vegetables after soaking until tender (Alabama).
  • Skip the soak for leafy greens, cabbage and tomatoes; add them straight to the pot.
  • Use the soaking water in cooking to keep the vitamins, NCHFP advises.

Best uses

Soups, stews, casseroles, sauces and stuffings.
