How to Can Green Beans

Step 1: Prepare the Green Beans

Wash the green beans thoroughly under cold running water. Trim both ends and remove any damaged beans. Cut the beans into 1 to 2-inch pieces, or leave them whole if preferred.

Step 2: Prepare the Jars

Wash jars, lids, and bands with hot soapy water. Keep the jars hot until ready to fill.

Step 3: Pack the Beans

Pack the prepared green beans tightly into hot jars, leaving 1 inch of headspace.

Step 4: Add Salt (Optional)

Add:

• 1 teaspoon canning salt per quart jar
• ½ teaspoon per pint jar

Salt is optional and used mainly for flavor.

Step 5: Add Boiling Water

Pour boiling water over the beans, maintaining 1 inch of headspace.

Step 6: Remove Air Bubbles

Slide a bubble remover around the inside of the jar. Add more boiling water if needed to maintain the proper headspace.

Step 7: Wipe and Seal

Wipe the jar rims with a clean damp cloth. Place the lids on the jars and screw the bands on until fingertip tight.

Step 8: Pressure Can

Place the jars in the pressure canner according to the manufacturer’s instructions.

Process:

Pint Jars

• 20 minutes

Quart Jars

• 25 minutes

Pressure:

• 10 PSI (weighted gauge canner)
• 11 PSI (dial gauge canner)

Adjust pressure for higher elevations according to your canner’s manual.

Step 9: Cool

Allow the pressure canner to return to zero pressure naturally. Carefully remove the jars and place them on a towel. Let cool undisturbed for 12–24 hours.

Step 10: Check the Seals

Press the center of each lid. Properly sealed lids will not flex. Remove the bands, label the jars, and store in a cool, dark place.

Tips for Successful Green Bean Canning

• Always use a pressure canner—green beans are a low-acid food and are not safe for water bath canning.
• Use fresh, crisp beans for the best quality.
• Leave exactly 1 inch of headspace.
• Do not overtighten the jar bands.
• Allow the canner to depressurize naturally.
• Label jars with the canning date.

Variations

French Style Green Beans

Slice the beans lengthwise before canning.

Whole Green Beans

Leave the beans whole if they fit comfortably in the jars.

Garlic Green Beans

Add one peeled garlic clove to each jar for extra flavor.

Spicy Green Beans

Add a small dried chili pepper or red pepper flakes before processing.

Herb Green Beans

Add dill, thyme, or oregano after opening the jar when preparing the beans for serving rather than before canning.

FAQs

Can you water bath can green beans?

No. Green beans are a low-acid vegetable and must be processed in a pressure canner for safe home preservation.

Do I have to add salt?

No. Canning salt is optional and is added for flavor rather than preservation.

How long do canned green beans last?

Properly sealed jars maintain their best quality for 12–18 months when stored in a cool, dark place.

Can I can whole green beans?

Yes. Whole beans work well as long as they fit inside the jars while maintaining proper headspace.

Why are my green beans floating?

Some floating is normal and usually results from trapped air. It does not affect safety if the jars sealed properly.

Can I reuse canning lids?

No. Always use new lids for a safe seal. Bands can be reused if they are clean and rust-free.

What pressure should I use?

Most recipes use 10 PSI for weighted-gauge canners and 11 PSI for dial-gauge canners, with adjustments for altitude.

How do I know if a jar sealed?

The center of the lid should be slightly concave and should not pop when pressed.
