We are in the middle of prime green bean season, where our plants are overflowing. Canning green beans allows you to put them up for casseroles and easy side dishes later in the year.
Canning green beans is different than canning jams and jellies. You will need a pressure canner; a water bath canner cannot safely can green beans. Green beans are a low acid food, which means botulism can grow faster.
If you are new to pressure canning, canning green beans is a great introduction. I prefer the raw pack method. What is a raw pack method? It means you will put the raw veggies in clean jars to the indicated headspace and fill the rest of the jar with boiling water. The pressure canner does all of the cooking for you.
Sound simple? Well, it is! Let’s get to it!
How to Can Green Beans – Raw Pack Method
First, you want to snap your green beans. You have to do this whether you plan to freeze or can these veggies. Snapping green beans can feel like a never-ending task. Kids help make this job easier and quicker!
After the ends are snapped off, you will want to wash them thoroughly, removing any dirt. At this time, put a pot of water on the stove to boil. You also will want to clean your jars. When you use a pressure canner, there is no need to boil or sterilize the jars beforehand. Just clean them and inspect for cracks and chips.
Once cleaned, it is time to fill up your jars! The jars fill better when the green beans are between one and two inches long. Fill the jars up, leaving one inch headspace at the top. Headspace is important for pressure canning!
You will want to add salt to the jars. I tried no salt before and the beans were bland, consequently those beans were great for casseroles, but not side dishes. Try 3/4 to 1 TSP of canning salt per jar.
Now is the time to put the indicated amount of water into your canner (check your manual), and turn the canner on medium to start heating up the water. After you add the salt, ladle in the boiling water, leaving the one inch headspace! After filled with boiling water, use your included tool for checking headspace or a wooden skewer to move around the jar, popping air bubbles.
Wipe off the rim of the jar and put on the lid. Your jars are ready to go into the canner!
Processing the Green Beans
Put your jars into the canner and close the lids. At this point, it is best if you follow your canners instructions. However, most of them follow the same type of instructions. You need to allow the canner to gain heat, and it will push out steam until the lid is locked. You need to put the valve over on top, allowing it to gain pressure.
Green beans should be processed at 11 pounds of pressure for 20 minutes for pints or 25 minutes for quarts. Your manual should have specific times; make sure that you double check! You need to process them for the correct amount of time to ensure any bacteria and spores are killed.
Once the jars are processed, turn off the heat and allow the canner to de-pressurize on its own. It can take up to 30 minutes for this to happen. Once unlocked, make sure that you open the lid AWAY from your face. The steam could burn you!
Lift the jars out of the canner and place them on a dry towel. Doing so helps to avoid breaking from the shock of the temperature change. Let the jars set for 24 hours.
Canning green beans couldn’t be easier! We had a small batch this time, but by the end of the season, our shelves will be lined with jars.
