Preserving homemade soup in mason jars is a great way to enjoy your favorite soups throughout the year while maintaining their freshness and nutritional value. This method of preservation is not only convenient but also offers a healthy alternative to canned soups found in grocery stores. However, to ensure the soup remains safe to eat and retains its quality, it’s crucial to follow the correct storage and canning procedures. In this article, we’ll delve into the steps and considerations for storing homemade soup in mason jars, covering the preparation, canning process, and safety guidelines.
Understanding the Basics of Canning Soup
Before diving into the specifics of storing homemade soup in mason jars, it’s essential to understand the basics of canning. Canning involves heating the food to a high temperature to kill off any bacteria and then sealing it in airtight containers. This process creates a vacuum seal that prevents new bacteria from entering the container, thus preserving the food. For soups, this process is a bit more complex due to their high water content, which can lead to the growth of bacteria if not heated and sealed properly.
Preparation is Key
Preparing your soup for canning involves several steps. First, you need to ensure your soup is hot and at the right acidity level. Most soups are low-acid foods, which means they require a pressure canner to achieve the high temperatures necessary to kill off bacteria like Clostridium botulinum, which can cause botulism. However, if you’re adding high-acid ingredients like tomatoes or citrus, you might be able to use a water bath canner, but this depends on the overall acidity of the soup.
Acidity and Its Role in Canning
Understanding the pH level of your soup is crucial. A pH level of 4.6 or lower is considered high-acid, which reduces the risk of bacterial growth. If your soup doesn’t naturally fall into this category, you can add acidic ingredients to lower the pH. However, always follow tested recipes and guidelines to ensure you’re achieving the right balance without compromising the taste or safety of your soup.
The Canning Process for Homemade Soup
The actual canning process involves several detailed steps:
- Prepare Your Equipment: This includes mason jars, lids, a canner (either a water bath canner or a pressure canner, depending on your soup’s acidity and the altitude at which you’re canning), and a utensil for removing air bubbles.
- Fill the Jars: Ladle the hot soup into the prepared jars, leaving the recommended headspace to allow for expansion during heating. Remove any air bubbles by running a non-metallic utensil, like a plastic spatula, around the inside of the jar.
- Seal the Jars: Place the lids and rings on the jars, tightening the rings until they’re just finger-tight. This allows for the air to escape during the canning process but still maintains a seal.
- Process the Jars: Place the jars into the canner, ensuring they’re covered by at least an inch of water for a water bath canner, or follow the manufacturer’s instructions for a pressure canner. Process the jars for the recommended time, which varies based on the type of canner, altitude, and the specific recipe.

After the canning process, let the jars cool on a wire rack, undisturbed, for 12 to 24 hours. This allows the seals to set. Check the seals after this period by pressing on the top of the lid; if the lid does not move and the seal is tight, the jar is sealed properly. Store the sealed jars in a cool, dark place, such as a pantry or cupboard. Always check the jars before storage for any signs of imperfect seals or damage.
Signs of Spoilage
It’s crucial to monitor your canned goods for signs of spoilage. Check for swelling, leaking, or corrosion on the jars. Any jar that is damaged or shows signs of spoilage should be discarded immediately to prevent foodborne illness.
Safety Considerations
Safety is paramount when canning homemade soup. Always follow tested recipes and canning procedures from reputable sources, such as the USDA’s Complete Guide to Home Canning. This guide provides detailed information on canning various foods, including soups, and ensures that your methods are safe and effective. Additionally, be mindful of altitude, as it affects the boiling point of water and thus the canning time and pressure required.
Common Mistakes to Avoid
Several common mistakes can lead to unsafe or spoiled canned goods. These include not heating the soup to the right temperature, not leaving enough headspace, and not processing the jars for the recommended time. Always prioritize caution and refer to trusted resources if you’re unsure about any aspect of the canning process.
In conclusion, preserving homemade soup in mason jars can be a rewarding way to enjoy your culinary creations year-round, provided you follow the proper canning and safety guidelines.
