Canning Tomato Soup Recipe (2024)

FAQs

How long is homemade canned tomato soup good for? ›

As long as the can is in good shape, the contents should be safe to eat, although the taste, texture and nutritional value of the food can diminish over time. Home canned foods should be used within 1 year.

If the tomatoes have not been acidified prior to canning you are risking the possibility of bacterial growth, which can be fatal. If you just canned them, and they haven't been stored, you might be able to open the jars and start over, or maybe freeze them.

Swirl some red wine vinegar into the soup and serve with a stack of mozzarella and fresh basil leaves on a toasted baguette. Add a drizzle of pesto (homemade or store bought) and finish with toasted pine nuts and croutons. Add a teaspoon or two of Thai red curry paste and some cooked rice, then top with cooked shrimp.

To ensure safe acidity in whole, crushed, or juiced tomatoes, add 2 tablespoons of bottled lemon juice, 4 tablespoons of 5 percent vinegar, or ½ teaspoon of citric acid per quart of tomatoes. For pints, use 1 tablespoon of bottled lemon juice, 2 tablespoons of 5 percent vinegar, or ¼ teaspoon of citric acid.

As a general rule of thumb, most canned foods (for example, canned tuna, soups, and vegetables) can be stored for two to five years, and high-acid foods (canned juices, tomatoes, pickles) can be stored for a year up to 18 months, according to the USDA. Watch out for dents and bulges in cans, though.

Low acid canned goods like vegetables, canned meats, and soups should be eaten within 2-3 years past their expiration date.

The short answer to the question is “Yes, to ensure safety, acid in the form of lemon juice, citric acid or vinegar must be added to tomatoes that will be processed by a pressure canning option”.

Acidifying Home-Canned Tomatoes and Tomato Products

*Note: Recipes list lemon juice or citric acid but vinegar in listed amounts may be used instead. Sugar may be added to offset the sour flavor (up to 1 teaspoon per pint or 2 teaspoons per quart).

When you add baking soda to tomato soup (or sauce, or chili), it neutralizes the acid in the tomatoes. Not only will this make the tomatoes taste less acidic (good news if your tomatoes turned out more sour than you expected), but it also means that you can now add milk to your soup without risking curdling it.

Garlic: Fresh or powdered garlic adds a robust, savory flavor to tomato sauce. You can sauté minced garlic in a bit of olive oil before adding the canned sauce to release its flavors. Onion: Chopped or minced onions, whether white or red, can provide a subtle sweetness and depth of flavor.

For the most intense tomato flavor, include a couple tablespoons of tomato paste. To get the most out of it, add it to the pan when aromatics like onion and garlic are softened, but before adding the tomatoes. Let the paste cook, stirring frequently, for a few minutes, or until it starts to darken in color.

Here's why. Bottled lemon juice is standardized, or uniformly acidified, per FDA regulations. Therefore, it is consistent which provides a known level of safety for food preservation. The final acidity of a food product is critical to deter the growth of microorganisms that can cause spoilage or foodborne illness.

Boiling-water bath: pints – 40 minutes; quarts – 45 minutes. Dial-gauge pressure canner: pints or quarts – 15 minutes at 11 PSI or 20 minutes at 6 PSI. Weight-gauge pressure canner: pints or quarts – 15 minutes at 15 PSI or 20 minutes at 10 PSI.

While canned goods past their "best-by" date may not taste optimal, there's no real health risk in consuming canned goods as long as they remain in good condition. Here's why: The food in the container is commercially sterile and a vacuum seal prevents any new bacteria from getting in, so it will not spoil.
