When canning potato soup, fill the hot canning jars with the cooked potato soup, leaving 1-inch headspace, and process in a pressure canner for 35 - 40 minutes. Once the canning process is complete, store the cooled jars in a dry, dark place for up to a year.
Is it Safe to Water Bath Can Potato Soup?
The National Center for Home Food Preservation (NCHFP) states water bath canning is unsafe for potato soup due to the insufficient temperatures reached during the process. Water bath canning uses temperatures of around 212°F.
To safely preserve low-acid foods like potato soup, pressure canning is necessary to reduce the risk of Clostridium botulinum, a bacteria that causes botulism. Pressure canners reach a higher temperature range of 240°F to 250°F which increases the internal temperature of the canned soup and kills harmful bacteria.Print
Can You Can Baked Potato Soup?
Baked potato soup is a delicious and popular variation of potato soup, and it can be safely preserved through the canning process. You may add ingredients such as cooked bacon and chives to the soup before canning.
However, dairy ingredients, including cheese, milk, and cream, cannot be safely included in your baked potato soup recipe. For the best results, add fresh dairy ingredients just before eating the soup after heating it from the jar.
Can You Can Soup with Milk In It?
Authoritative sources, including the USDA and the National Center for Home Food Preservation, do not recommend canning milk or dairy products. They suggest adding it when reheating or serving the soup. This ensures that the dairy is heated to a safe temperature of 165°F and consumed immediately.
What Kind of Jars Do You Need to Can Soup?
Home canning jars, such as Ball or Mason jars, should be used for canning soup. These jars are made of tempered glass and have a two-piece lid consisting of a metal band and a flat metal lid with a sealing compound. Common sizes for canning soup include 16-ounce pint jars and 32-ounce quart jars.
Regular-mouth and wide-mouth jars can be used for canning soup, but wide-mouth jars are more convenient for filling and emptying the contents, especially for chunky soups. They allow easier access for ladles or spoons during serving and cleaning. Regular-mouth jars are suitable if you prefer a narrower opening or already have them on hand.
