Dehydrating green beans is an easy way to preserve your garden harvest while retaining flavor and nutrition. With just a few simple steps you can enjoy crisp tasty green beans year-round.
Benefits of Drying Green Beans
Dehydrating offers many advantages over other preservation methods
- Maintains more nutrients than canning or freezing
- Intensifies natural flavors as moisture evaporates
- Allows for long-term storage without refrigeration
- Creates lightweight, easy-to-store ingredients
- Enables enjoying garden fresh beans all year
- Allows customizing beans for recipes by rehydrating
Dried green beans are great for snacking, adding to soups and casseroles, and reconstituting into side dishes. Their concentrated flavor makes them ideal for seasoning as well.
Selecting Green Beans for Drying
Choose fresh, tender green beans for dehydrating. Overly mature beans will be tough and fibrous The best beans
- Have smooth, vibrant pods without bulges or lumps
- Snap easily when bent and are crisp
- Are 3-6 inches long depending on variety
- Have small, underdeveloped seeds
- Show no sign of disease, bruising or decay
Pick beans early in the morning when they are coolest and most crisp. Avoid wilted or limp beans. For prime texture and taste, start dehydrating beans the same day they are harvested.
Preparing Green Beans for Drying
Follow these steps to prep green beans for the dehydrator:
- Wash thoroughly under cool running water.
- Snap off stem and tip ends. Leave beans whole.
- Cut longer beans into uniform 2-3 inch pieces if desired.
- Blanch for 3-5 minutes until bright green.
- Shock in ice water bath to stop cooking process.
- Pat dry with clean towels or spin in salad spinner.
Blanching green beans before dehydrating pre-cooks them slightly to accelerate drying time. It also helps retain color and deactivate enzymes that cause loss of flavor and texture during storage.
How to Dehydrate Green Beans
Drying green beans requires only a few steps:
- Arrange beans in a single layer on dehydrator trays.
- Make sure there is adequate airflow around the beans.
- Set temperature between 125°F to 135°F.
- Dry for 6 to 10 hours, checking periodically.
- Beans are done when brittle and shriveled.
Rotate trays and stir beans occasionally to ensure even drying. Lower temperatures preserve more nutrients but lengthen drying time.
Testing Dryness of Green Beans
Green beans are fully dehydrated when they display these characteristics:
- Hard and brittle with no flexibility
- Shrunken and wrinkled with no puffiness
- Dry to the touch inside and out
- No visible moisture inside when cut
- Lightweight and hollow sounding when tapped
The drying time can vary based on bean size, moisture content and the dehydrator used. Keep testing beans until all moisture has evaporated.
Conditioning and Storing Dried Beans
After dehydrating, conditioning helps equalize moisture and prolong shelf life:
- Place beans in an airtight container for 24-48 hours.
- Excess moisture will distribute evenly throughout beans.
- If any dampness develops, dehydrate beans for longer.
Once conditioned, store beans in airtight containers out of light and heat:
- Glass jars, plastic containers or resealable bags work well.
- Store in pantry up to 1 year.
- For longer storage, keep beans in the refrigerator or freezer.
For maximum flavor and nutrition retention, use dried green beans within 1 year. Properly stored, they can last for 2-3 years.
Rehydrating and Using Dehydrated Beans
Dried green beans plump up quickly when soaked or cooked in liquid.
- For soups, casseroles and side dishes, simmer beans in water or broth until tender.
- For snacking, soak in water for 30-60 minutes to rehydrate.
- Adjust soaking time to reach desired texture.
- Use rehydration liquid for a nutrient boost in recipes.
Get creative with reconstituted green beans in fried rice, pasta salads, omelets, salsa and more. Their concentrated flavor is delicious.
Making Green Bean Powder
For an easy seasoning, grind dehydrated beans into a fine powder:
- Use a blender, food processor or coffee grinder.
- Work in small batches to prevent clumping.
- Let beans cool completely before grinding.
- Store powder in airtight bottles or jars.
Sprinkle green bean powder on soups, dips, eggs, roast vegetables and meat for a nutritional boost. The options are endless!

- Blue Lake – Prolific producer, stringless and slow to develop seeds
- Contender – Reliable yields, straight 5-6 inch pods
