Creating your own canned black beans at home is a rewarding way to build a high-quality food pantry. Home canning allows you to control the sodium content, avoid chemical preservatives, and ensure the texture of the beans is exactly to your liking. While the process requires specific equipment and a commitment to safety, the result is a shelf-stable staple that is far superior to store-bought versions.
Essential Equipment and Ingredients
To safely can black beans, you must use a pressure canner. Because beans are a low-acid food, a standard water bath canner cannot reach the temperatures necessary to kill botulism spores. In addition to a pressure canner, you will need glass canning jars (pints or quarts), new lids, and screw bands.
For the ingredients, you will need dry black beans, water, and optionally, canning salt or sea salt. One pound of dry black beans typically yields about two pint jars or one quart jar. Ensure your dry beans are clean and free of stones or shriveled debris before you begin.
Step 1: Sorting and Soaking
The first step in making canned black beans is to sort and rinse the dry legumes. Spread the beans on a flat surface or a rimmed baking sheet. Look for small pebbles, clumps of dirt, or damaged beans and discard them. Once sorted, place the beans in a large bowl or pot and rinse them thoroughly under cool running water.
Soaking is a critical part of the process. It helps rehydrate the beans and reduces the sugars that cause digestive discomfort. You have two options for soaking:
- Overnight Soak: Cover the beans with at least three inches of water and let them sit for 12 to 24 hours in a cool place. This is the traditional method and usually results in the best texture.
- Quick Soak: Place the beans in a pot and cover with water. Bring the water to a boil for two minutes. Turn off the heat, cover the pot, and let the beans soak for one hour.
Regardless of the method, you must drain and rinse the beans after soaking. Discard the soaking water, as it contains the starches and sugars you want to remove.
Step 2: Pre-Cooking the Beans
After soaking and rinsing, place the beans in a large pot and cover them with fresh water. Bring the pot to a boil, then reduce the heat to a simmer. Allow the beans to cook for 30 minutes.
It is important to note that the beans should not be fully cooked or soft at this stage. They will finish cooking inside the jars during the pressure canning process. Pre-cooking ensures that the beans have expanded sufficiently so they do not burst the jars or absorb all the liquid during processing.
Step 3: Preparing the Jars
While the beans are simmering, prepare your canning jars. Wash the jars, lids, and bands in hot, soapy water and rinse them well. Keep the jars warm to prevent them from cracking when you add the hot beans and liquid. You can keep them in a low oven or in the pressure canner with a few inches of simmering water.
Step 4: Filling the Jars
Using a canning funnel, ladle the hot beans into the warm jars. For a pint jar, fill it with beans until they reach about an inch below the rim. If you are using salt, add half a teaspoon to each pint or one teaspoon to each quart.
Next, pour the hot cooking liquid (or fresh boiling water) over the beans. You must leave exactly one inch of headspace at the top of the jar. Headspace is the empty gap between the surface of the liquid and the top of the jar rim. This space is vital for a proper vacuum seal. Use a non-metallic bubble remover or a plastic spatula to gently stir the beans and release any trapped air bubbles. Adjust the liquid level if necessary to maintain that one-inch headspace.
Step 5: Sealing and Processing
Wipe the rims of the jars with a clean, damp cloth or a paper towel dipped in white vinegar. Any residue on the rim can prevent the lid from sealing. Center a new lid on the jar and screw the band on until it is “fingertip tight.” This means you should tighten it until you feel resistance, but do not use excessive force.
Place the jars into your pressure canner, which should contain two to three inches of hot water. Secure the canner lid. Turn the heat to high and allow steam to vent from the pipe for a full 10 minutes before placing the weighted gauge or regulator on the vent.
Once the canner reaches the correct pressure—usually 10 to 11 pounds depending on your altitude—start your timer.
- Pint jars: Process for 75 minutes.
- Quart jars: Process for 90 minutes.
Step 6: Cooling and Storage
When the processing time is finished, turn off the heat and let the pressure drop to zero naturally. Do not attempt to force the pressure down by cooling the canner with water or removing the weight early. Doing so can cause “siphoning,” where the liquid is forced out of the jars.
Once the pressure is gone, carefully remove the lid and let the jars sit inside for 10 minutes. Use a jar lifter to move them to a towel-lined surface. Let them sit undisturbed for 12 to 24 hours. You will likely hear the “ping” of the lids sealing. After they have cooled completely, check the seals by pressing the center of the lid; it should not flex or pop. Store your home-canned black beans in a cool, dark place for up to one year.
Frequently Asked Questions
Can I can black beans without a pressure canner? No. Low-acid foods like beans require the high temperatures only a pressure canner can provide (240°F or 115°C) to eliminate the risk of botulism. A water bath canner only reaches the boiling point of water, which is insufficient.
Why did my beans absorb all the liquid in the jar? This usually happens if the beans were not soaked or pre-cooked long enough. They continue to expand during the canning process. To prevent this, ensure a full 30-minute simmer before packing the jars and maintain the correct one-inch headspace.
Do I have to soak the beans before canning? While some “no-soak” methods exist, soaking is highly recommended. It improves the texture, makes the beans easier to digest, and prevents the beans from expanding too much and breaking the seal of the jar.
Is it safe to add seasonings like garlic or onions to the jars? Yes, you can add dry spices like cumin, chili powder, or garlic powder. However, be cautious with fresh vegetables; adding large amounts can change the acidity and density, potentially requiring a different processing time. Most experts recommend seasoning the beans when you open the jar to eat them.
How long do homemade canned black beans last? When stored in a cool, dark place with a proper seal, home-canned black beans are best used within 12 to 18 months. Always inspect the jar for a broken seal or off-smells before consuming.
