Canning is an age-old practice that not only preserves food but also enhances its flavors, saving it for later enjoyment. One food that often comes to mind when thinking of preserves is soup. Have you ever wondered, “Can soup be canned?” If so, you’re in the right place! This comprehensive article will delve into the world of soup canning, exploring its benefits, methods, safety concerns, and tips for creating the perfect canned soup.
The Basics of Canning Soup
Before diving deeper, it’s essential to understand what canning entails. Canning involves sealing food in containers and heating them to kill bacteria and other pathogens, creating a vacuum seal that keeps the food safe and preserved for an extended time.
When it comes to soups, the process can vary depending on the ingredients used and the type of canning method you choose.
Types of Canning Methods
There are two main methods of canning: water bath canning and pressure canning. Each method has its unique applications and benefits.
Water Bath Canning
This method is suitable for high-acid foods like tomatoes and pickles. However, soups—especially those containing low-acid ingredients like vegetables and meat—are not typically safe for water bath canning.
Pressure Canning
On the other hand, pressure canning is essential for low-acid foods. Many soups fall into this category, as they often contain a mix of vegetables, meats, and broths. Pressure canning raises the temperature inside the canner to kill harmful bacteria and ensures the soup is safe for long-term storage.
Why Canning Your Own Soup Is Beneficial
Canning your soup has several benefits that can enhance your culinary experience:
1. Control Over Ingredients: When you can your soup, you have full control over every ingredient, allowing you to choose organic and fresh items. You can tailor your soup to suit dietary restrictions or preferences, such as gluten-free or vegan options.
2. Cost-Effectiveness: Making large batches of soup can be more economical than buying pre-made soups. Canning allows you to take advantage of seasonal produce, preserving it for times when fresh ingredients may be less affordable.
3. Convenience: A canned soup is an easy and quick meal option. You can simply grab a jar from your pantry, heat it up, and enjoy a home-cooked meal in no time.
4. Reduced Waste: Canning helps reduce food waste by allowing you to preserve leftovers or excess produce rather than letting them spoil.

– Wipe the rim of the jar with a wet cloth to ensure a good seal.
Step 4: Seal the Jar
Place the lid on top of the jar and screw on the canning ring until it’s fingertip-tight. Avoid over-tightening, as this can prevent the jar from sealing properly.
Step 5: Process the Jars
Place the filled jars into the pressure canner, following the manufacturer’s instructions. Process the jars according to the recipe’s guidelines, usually between 60-90 minutes, depending on the type of soup and altitude.
Step 6: Cool and Store
Once processed, turn off the heat and allow the pressure canner to depressurize naturally. Afterward, carefully remove the jars using a jar lifter and place them on a dishcloth or towel to cool completely—this usually takes 12-24 hours.
After the jars cool, check the seals by pressing the center of the lids. If it does not pop back, the jar has sealed correctly. Store sealed jars in a cool, dark place for up to a year.
Important Safety Considerations
Canning can be a rewarding experience, but it is crucial to prioritize safety to prevent potential foodborne illnesses. Here are some safety tips to keep in mind:
1. Use Proper Canning Equipment: Always use a modern pressure canner that is tested for safety. Avoid using old pressure cookers that may not meet current safety standards.
2. Follow Acid Levels:** High-acid foods can be safely processed in a water bath canner, but low-acid foods, including most soups, must be processed in a pressure canner. Failing to do so can lead to dangerous bacteria, such as botulism.
3. Follow Recipes Carefully: Always use tested recipes from reputable sources to ensure appropriate processing times and ingredient ratios.

When preparing soup for canning, start by cooking the ingredients thoroughly. This not only enhances the flavor but also reduces the risk of spoilage. After cooking, ladle the hot soup into sterilized jars, ensuring you leave the appropriate headspace, usually about one inch from the top. Proper headspace is critical for creating a vacuum seal as the jars cool.
Once the jars are filled, wipe the rims clean with a damp cloth to remove any food particles that could compromise the seal. Place the lids on the jars and screw on the bands until fingertip tight. Finally, process the jars in the canner according to the specific recipe guidelines, which dictate the correct pressure and processing time.
What are the safety concerns with canning soup?
Canning soup carries certain safety risks, particularly with low-acid foods. If not processed correctly, there’s a danger of botulism, a rare but potentially fatal illness caused by toxins from the bacterium Clostridium botulinum. To mitigate this risk, always use a pressure canner for low-acid soups and follow time and temperature guidelines specific to your recipe.
It’s also vital to check seals after the canning process. If a jar isn’t sealed properly, it can lead to spoilage, so store any unsealed jars in the refrigerator and consume the contents promptly. Additionally, ensure proper storage conditions—keep canned soups in a cool, dark place to prolong shelf life.
Can I reuse canning jars and lids?
You can reuse canning jars as long as they are in good condition—check for cracks, chips, or any signs of damage. However, it’s essential to use new lids for each canning session. The sealing compound on used lids may not perform as well, leading to potential failures in creating a proper vacuum seal after canning, which can compromise food safety.
Ensure to thoroughly clean your jars before reuse. A good wash in hot, soapy water, followed by sterilization in boiling water or the dishwasher, will prepare them for the next batch of soup. Remember that while jars can be reused, the lids should always be fresh to ensure a reliable seal.
How long can canned soup be stored?
Properly canned soup can typically be stored for one to two years, or even longer if stored under ideal conditions. To maximize shelf life, keep the jars in a cool, dark, and dry place, away from direct sunlight and temperature fluctuations. Over time, the quality of the soup may decline even if it remains safe to eat, so it’s best to consume it within the first year for optimal flavor and texture.
Always check for signs of spoilage before consuming canned soup. If you notice any unusual odors, discoloration, or bulging lids, it’s best to err on the side of caution and discard the jar. Proper storage and careful monitoring can help ensure that your home-canned soup remains safe and delicious over time.
Can I add pasta or rice to my canned soup?
While you can add pasta or rice to your soup before canning, it’s generally not recommended due to texture changes and potential overcooking. These ingredients absorb moisture over time, which can lead to a mushy consistency once the soup is opened. Instead, many home canners prefer to can the soup without these ingredients and add them during preparation when ready to eat.
If you choose to include pasta or rice, ensure they are cooked only partially, leaving them firm prior to canning. This can help mitigate the mushiness issue. Just keep in mind that even partially cooked additions may still affect the final texture, so it might be more favorable to make additions fresh upon serving.
Is it necessary to pressure can my soup?
Yes, if your soup is low in acid or contains ingredients like meat, vegetables, or beans, pressure canning is necessary to ensure safety. The high temperatures achieved in a pressure canner are vital for destroying harmful bacteria and spores that can cause foodborne illnesses. Water bath canning is only safe for high-acid foods, such as fruit-based soups, where the acidity helps prevent bacterial growth.
Always follow reputable canning guidelines that specify whether pressure canning or water bath canning is required for your specific recipe. Adhering to these guidelines is crucial for ensuring the safety and longevity of your home-canned soups.
