Canning your own vegetable broth is one of the simplest yet most rewarding ways to stock your pantry with a homemade, nutritious base for soups, stews, and just about anything else.
Combine all ingredients in a large stockpot. Bring to a boil over medium-high heat. Once boiling, reduce heat and simmer uncovered for 2 hours.
Wash and sterilize your jars. Set the pressure canner on low heat with water, ensuring the temperature reaches 180°F (82°C).
Once the broth has simmered, strain it through a cheesecloth-lined colander into another pot. Discard the solids.
Reheat the broth to a boil. Ladle hot broth into prepared jars, leaving 1 inch (2.5 cm) of headspace. Wipe the rims of the jars with a clean cloth, then place lids and screw on bands until fingertip-tight.
Process jars at 10 lbs pressure for 20 minutes (pints) or 25 minutes (quarts). Adjust for altitude as necessary (see notes).
Let jars cool for 12 hours. Check seals, label, and store in a cool, dark place for up to 1 year.
Notes
This recipe is a great base, but feel free to experiment by adding other herbs or vegetables to suit your taste. Just be sure to avoid starchy vegetables like potatoes or parsnips, as they can cause cloudiness and may interfere with the canning process.Red bell peppers are key to the flavor of this broth—though I never included them in my veggie broth before trying Ball’s recipe, they’re now a staple in my version.Mushrooms are not fully tested for home canning and may be risky, so it’s best to avoid adding them for safety reasons.This recipe doesn’t include salt, as everyone's preference for salt varies. I prefer to can the broth without it and add salt when I use it. However, if you prefer to add salt, a good guideline is ¼ tsp per quart or 1/8 tsp per pint.
Altitude Adjustments for Canning Vegetable Broth
If you live above 1,000 feet in elevation, you'll need to adjust the pressure used during the canning process. Here are the altitude adjustments for pressure canning vegetable broth:For Dial Gauge Canners:
