Dehydrated green beans are a healthy alternative to potato chips—they're low in calories, fat and sodium and high in fiber. Pack them for camping or long road trips, or add them to soups, stews and casseroles. They're available at many grocery stores, but they're actually surprisingly easy to make. You don't even need a food dehydrator; an oven works just as well but takes longer.

How to Dehydrate Green Beans for a Snack

Step 1

Wash the green beans in cold water.

Step 2

Cut off the ends and cut the beans into 1-inch pieces.

Step 3

Steam blanch the beans. Place a few inches of water in the bottom of a pot; place the steamer pan or wire basket into the pot and make sure the water doesn't touch the bottom of the steamer pan. Bring to a boil. Place beans in steamer pan and steam 3 to 4 minutes.

Step 4

Remove beans from the steamer and plunge into cold or ice water for 5 minutes to stop the cooking process. Strain the beans.

Step 5

Place green beans on a cookie sheet in a single layer. Freeze for 45 minutes.

Step 6

To dehydrate the green beans in the oven, place the cookie sheet of beans in the oven at 140 degrees Fahrenheit until crisp and all moisture has been removed. Cooking times vary and may take 8 to 14 hours.

If using a food dehydrator, place beans on the dehydrator tray and cook at 135 degrees Fahrenheit for 8 to 12 hours until crisp.
