Here are the benefits of pressure canning:
- Safety First: Proper pressure canning eliminates bacteria and ensures a perfect seal.
- Nutrient Retention: This method locks in vitamins and minerals, preserving the health benefits of green beans.
- Superior Flavor: Your canned beans will taste garden-fresh even months later.
Let’s dive into what you’ll need to get started.
Essential Tools and Ingredients
Having the right tools and ingredients at your fingertips will make the process seamless and enjoyable.
Ingredients:
- Fresh green beans (approximately 2 pounds per quart-sized jar)
- Boiling water
- Pickling salt (optional, for flavor)
Tools:
- Pressure canner (not a pressure cooker)
- Mason jars with lids and bands
- Jar lifter and funnel

Step-by-Step Guide: How to Pressure Can Green Beans
Step 1: Prepare Your Green Beans
- Harvest Fresh Beans: Use tender, firm, and blemish-free green beans for the best results.
- Wash Thoroughly: Rinse the beans under running water to remove dirt or debris.
- Trim and Cut: Snap off the ends of the beans and cut them into pieces about 1-2 inches long.
Step 2: Sterilize and Prepare Your Jars
- Wash and Sterilize: Clean jars, lids, and bands with hot soapy water. Sterilize by boiling in water for 10 minutes.
- Keep Warm: Leave jars in hot water until you’re ready to fill them. This prevents cracking when hot liquid is added.
Step 3: Pack the Jars
- Choose Your Packing Method:
- Raw Pack: Fill jars with raw green beans, leaving 1 inch of headspace.
- Hot Pack: Blanch beans in boiling water for 5 minutes, then pack them into jars while still hot.
- Add Optional Salt: For flavor, add ½ teaspoon of pickling salt per pint or 1 teaspoon per quart.
- Add Boiling Water: Pour boiling water into jars, ensuring beans are fully submerged. Maintain 1 inch of headspace.
Step 4: Seal the Jars
- Wipe jar rims with a clean towel to remove residue.
- Place lids on top and secure bands until fingertip-tight.
Step 5: Pressure Can the Green Beans
- Prepare the Pressure Canner: Add water per manufacturer’s instructions. Place jars in the canner using a jar lifter.
- Build Pressure: Heat the canner until steam escapes steadily for 10 minutes, then close the vent.
- Process Jars: Adjust to 10 PSI (pounds per square inch) and process:
- Pint Jars: 20 minutes
- Quart Jars: 25 minutes
- Altitude Adjustments: Increase pressure for altitudes above 1,000 feet (refer to your canner’s manual).
Step 6: Cool and Store
- Allow the pressure canner to cool and depressurize naturally. Do not force it open.
- Check seals: Press on the jar lids. If they don’t pop back, the seal is secure.
- Label jars with the date and store them in a cool, dark place. Properly canned green beans can last up to 1 year.
FAQs About Canning Green Beans
Can I use a regular pressure cooker?
No, only use a pressure canner specifically designed for canning low-acid foods.
What should I do if a jar doesn’t seal?
Refrigerate and consume within a few days or reprocess with a new lid.

Increase the pressure per your canner’s manual (e.g., 15 PSI above 1,000 feet).
Common Mistakes to Avoid
- Skipping Sterilization: Always sterilize jars to prevent contamination.
