Canning green beans begins by creating a pickle brine by combining water, vinegar, and pickling salt. Bring the mixture to a boil and pour this over raw, trimmed green beans, leaving 1/2” headspace. Process in a water bath canner for 5-15 minutes.
Is it Possible to Safely Can Green Beans in a Water Bath?
The USDA recommends water bath canning for high-acid foods. If pickled first, green beans are suitable for water bath canning.Print
How Long Do You Process Green Beans in a Water Bath Canner?
The time needed to process green beans in a water bath canner depends on elevation.
Processing time for pickled green beans in a boiling-water canner:
|Altitude (ft)||0 – 1,000||1,001 – 6,000||6,000 +|
|Raw Pack Pints||5 mins||10 mins||15 mins|
Why Do Green Beans Need to Be Pickled for Water Bath Canning?
Water bath canning low-acid foods isn’t safe. It creates the perfect breeding ground for Clostridium botulinum, the bacteria which causes botulism.
Water bath canning is safe for high-acid foods because the acidity of the food naturally inhibits the growth of any C. botulinum spores. Pressure canning and the temperatures reached through that canning process are needed to kill the spores present in foods with low acidity.
How Much Headspace is Needed When Canning Green Beans?
It is necessary to leave ½ inch of headspace when canning pickled green beans in a water bath canner. 1-inch headspace is required for green beans canned using a pressure canner.
What are the Benefits of Canning Green Beans?

How to Store Canned Green Beans
Canned green beans should be stored in a cool, dark, dry place. A temperature range of 50-70 degrees F is ideal. It is important that they are not exposed to direct sunlight and are stored in a low-humidity environment to maximize shelf life.
What is the Difference Between Water Bath Canning and Pressure Canning?
Water bath canning and pressure canning are two different methods of canning.
Water bath canning involves submerging packed jars into a large pot of boiling water and processing them for a set amount of time. Water bath canning is used for more acidic foods, like fruits, jams, and pickles.
Pressure canning is a canning method that requires the use of a specialized pressure canner (not to be confused with a pressure cooker). Pressure canners heat jars to a temperature higher than boiling water by using pressure. Pressure canning is used for less acidic foods, like vegetables, meat, and soup.
