How to Rehydrate a Dried Onion

By Tom Ross

Dried onions are a tasty and convenient alternative to fresh onions. Dehydrated onions perform very well as a substitute for fresh onions when cooked in recipes or used as a condiment. They are simple to rehydrate, and the ratio of how much dried onion to fresh onion is simple to determine. Rehydrating dried onions requires less time, effort and cleanup than peeling and chopping fresh onions. Dehydrated onions are always available when needed and do not sprout or rot while in storage.

Dehydrated onions are as flavorful as fresh onions but lose some nutritional value.

Step 1

Add an equal amount of warm tap water to an equal volume of dried onions; 1 cup of water to 1 cup of dried onions.

Step 2

Allow the dried onion to sit for approximately 15 to 20 minutes to fully absorb the water.

Step 3

Drain off excess moisture if the recipe doesn't call for it. Meat loaf, guacamole or condiments for burgers and hot dogs are some of the dry menu items that do not tolerate the excess moisture from rehydration.

Step 4

Use the excess moisture as an additional flavoring agent in moisture-rich recipes such as soups, sauces or stews.
