How to Can Green Beans

Are you growing green beans in your garden this year? Or maybe you just want to make the most of seasonal produce from your local market? Green beans are a delicious and healthy vegetable that you can preserve for year-round enjoyment.

All you have to do is can them. Canning is a simple process that allows you to maintain the freshness and nutritional value of green beans, ensuring that you always have them on hand for your favorite recipes. It’s an excellent way to reduce food waste and stock up your pantry with healthy, ready-to-use vegetables.

Whether you’re a beginner or seasoned canner, this guide from Blain’s Farm & Fleet will walk you through all the steps to successfully can green beans at home.

What You’ll Need

Start by gathering your supplies. You’ll need:

• Fresh green beans
• Mason jars with lids and bands
• Large pot
• Pressure canner
• Bubble remover or non-metallic spatula

Step 1: Preparing the Green Beans

Choose fresh, tender green beans. Wash them thoroughly under running water to remove any dirt or debris. Then, trim the ends. You can cut up the beans into smaller pieces or leave them whole.

You can hot pack or cold pack the green beans. Blanching is optional, but we recommend it to stop enzyme actions and preserve color and texture.

To blanch the green beans, bring a large pot of water to a boil. Add the beans, and boil for three to five minutes. Then, immediately transfer the beans to ice water to cool. Drain the water and set aside.

Step 2: Preparing the Jars

Sterilize your jars and lids by boiling them in water for 10 minutes. Keep them hot until you’re ready to use them.

Then, pack the beans tightly into the jars. Leave about one inch of headspace (the space between the liquid and the top of the jar). If you’d like, add one teaspoon of salt per quart jar for extra flavor. Use a ladle to fill the jars with the hot water, making sure to maintain that 1-inch headspace.

Use a bubble remover tool or a non-metallic spatula to remove air bubbles by gently stirring around the inside edge of the jar. Wipe the rims of each jar, put on the lids, and apply the bands.

Step 3: Processing in the Pressure Canner

Green beans have low acidity, so pressure canning is the best way to preserve them. Follow the manufacturer’s instructions for setting up your pressure canner.

Add two to three inches of water to the canner. Then, place the filled jars on the canner rack. Ensure the jars do not touch each other, and secure the lid on the canner.

Process the jars at 10 pounds of pressure. Process pint jars for 20 minutes and quart jars for 25 minutes. Adjust the pressure according to your altitude, if necessary.

Step 4: Cooling and Storing

After processing, turn off the heat and let the pressure return to zero before removing the lid. Carefully lift the jars and place them on a towel to cool for 24 hours.

Once cooled, check the seals by pressing in the center of each lid. If it doesn’t pop back, the jar is sealed correctly. If there are any jars that didn’t seal correctly, refrigerate them and use within a few days.

Label the jars with the date, and store them in a cool, dark place. Properly canned green beans can last up to one year.

Common Issues and Solutions

• Cloudy liquid: Cloudy liquid can be caused by hard water or table salt. Use canning salt and distilled water to prevent this.
• Floating beans: Beans may float because of air trapped inside. Ensure the beans are packed tightly and there are no air bubbles.
• Mold or spoilage: If there is any mold or spoilage, discard the contents immediately. Always use sterile equipment and follow processing times accurately.

Canning green beans is an easy process that yields delicious and long-lasting results. By following these steps, you can enjoy the taste of fresh green beans even when they’re out of season.
