Canning soup is a fantastic way to preserve your favorite flavors and ensure you have a convenient meal ready at any time. While many opt for a pressure cooker to expedite the canning process, it is entirely possible to can soup without one. This article will guide you through every step, from preparation to storage, ensuring you achieve delicious, safe results even without a pressure cooker.
Understanding the Basics of Canning Soup
Before diving into the actual process of canning soup, it is essential to familiarize yourself with the basics of canning. Canning is a method of preserving food by sealing it in containers, typically glass jars, and heating to destroy bacteria, yeasts, and molds.
One common method of canning is called the water bath canning method, which is best for high-acid foods. However, soups are often low-acid foods, which makes them better suited for pressure canning. Nevertheless, by understanding acidity levels and ensuring your soup is prepared correctly, you can still enjoy safe, delicious canned soups.

Preparing Your Soup
Creating a soup that is ideal for canning requires an understanding of texture and flavor. Here’s a simple process to prepare your soup for canning.
Choose a Base Recipe
Begin with your favorite soup recipe, or start with a basic vegetable soup as your foundation. Here is a straightforward vegetable soup recipe:
- 2 onions, chopped
- 2 carrots, sliced
- 2 stalks of celery, chopped
- 4 tomatoes, diced (or 1 can of diced tomatoes)
- 4 cups of vegetable broth
- 3 cloves of garlic, minced
- Salt and pepper to taste
Cooking Instructions
- In a large pot, heat a small amount of oil over medium heat.
- Add onions, carrots, and celery, and sauté until they are tender.
- Stir in the tomatoes, garlic, and any additional seasonings. Cook for a few more minutes.
- Pour in the vegetable broth and bring the mixture to a boil.
- Reduce heat and let simmer for about 20–30 minutes to meld the flavors. Ensure the vegetables are fully cooked.
Preparing the Jars and Lids
Before you start filling your jars, make sure they are properly cleaned and sterilized.
Cleaning the Jars
To ensure that your jars are sanitized, follow these steps:
- Wash the jars and lids in hot soap and water.
- Rinse thoroughly.
- Place the jars in a large pot of water, bringing it to a boil, and boil for at least 10 minutes. Allow them to air dry.
Warm Your Jars
Warm jars can help prevent breakage when filling with hot soup. You can keep them submerged in hot water while the soup is running.
Canning the Soup
Once your soup is cooked and the jars are prepared, you can begin the canning process.
Filling the Jars
Using a ladle and a funnel, fill each jar with hot soup, leaving about 1 inch of headspace at the top. It’s essential to maintain this space to ensure proper sealing and food safety.
Removing Air Bubbles
After filling the jars, use a clean utensil to slide around the inside edge of the jar. This process releases trapped air bubbles that could compromise the sealing process.
Sealing the Jars
Wipe the rims of the jars with a clean, damp towel to remove any food residue that may prevent a proper seal. Placing the lids on the jars, ensure they’re applied evenly and correctly.
Water Bath Canning Method
Since you’re not using a pressure cooker, you’re going to rely on the water bath canning method. Here’s how to do it efficiently.
Set Up Your Canner
- Fill a large pot or canner with water, ensuring you have enough to submerge the jars (about 3-4 inches of water).
- Use a rack or towel at the bottom of the pot to prevent direct contact of the jar on the heat source.
Cooking the Jars
- Once your jars are filled and sealed, carefully place them in the simmering water, ensuring they’re upright and not touching each other.
- Bring the water to a full rolling boil.
- Process jars for approximately 40–45 minutes, depending on your altitude. Higher altitudes may require longer boiling times.
Finishing Up
After the required time, carefully remove the jars using a jar lifter or tongs and place them on a towel or cooling rack. Allow the jars to cool completely before checking seals, which typically takes 12-24 hours. You’ll know the jars are sealed correctly if the lid doesn’t pop when pressed in the center.
Storing Your Canned Soup
Proper storage will ensure that your homemade canned soup remains fresh and delicious over time.
Labeling the Jars
When your jars have cooled, label them with the contents and the date of canning. This practice helps keep track of freshness and expiration dates.
Storage Conditions
Store your jars in a cool, dark place away from direct sunlight. A pantry or cellar is ideal, where the temperature remains consistent. Properly processed and sealed jars can last up to a year, but for best flavor and quality, consume them within six months.
Safety Tips for Canning Soup
Safety is paramount when canning at home. Here are essential tips to follow:
- Always use tested recipes to ensure your soup is safe for canning and has the correct acidity levels.
- Never reuse jar lids, as they may not seal effectively.
Common Signs of Spoilage
After canning your soup, watch for any signs of spoilage such as:
- Bulging lids
- Unpleasant odors upon opening
- Visible mold inside
If you notice any of these signs, it’s safest to discard the jar.
Conclusion
Canning soup without a pressure cooker is a rewarding process that can yield delicious results if done correctly. By following the steps outlined in this article, you can prepare, can, and store your homemade soups effectively and safely.
Whether you choose to enjoy them as hearty meals or convenient snacks, your canned soups will carry the warmth of home-cooked goodness throughout the year. So roll up your sleeves, gather your ingredients, and embark on this savory canning adventure!
What is the best way to can soup without a pressure cooker?
Utilizing the water bath canning method is the best approach for canning soup without a pressure cooker. When using this method, ensure that your soup has high acidity levels; this can be achieved by incorporating ingredients such as tomatoes or vinegar. The water bath process involves heating jars filled with soup in boiling water to kill bacteria and create a vacuum seal. Remember that this technique is not suitable for low-acid foods or meats, as it requires higher temperatures that a water bath cannot achieve.
Before starting the canning process, make sure that all your jars are sterilized. You can do this by boiling them in water for 10 minutes or running them through a dishwasher on a hot cycle. Once the jars are ready, fill them with your prepared soup, leaving about an inch of headspace at the top. Seal the jars with sterile lids and process them in a boiling water bath for the recommended time based on your altitude and recipe.
Can I can cream-based soups?
Canning cream-based soups is not recommended because dairy products can separate and change in texture once canned. The high temperatures during canning can also affect the cream’s safety, making it prone to spoilage. Instead of canning cream soups, consider freezing them in airtight containers. This method preserves the texture and flavor while ensuring safety.
If you’re looking for a way to include creamy flavor in your soups that you want to can, consider adding the cream after the canning process. You can prepare a base soup with safe-to-can ingredients and add the cream when serving, maintaining both safety and quality.
What types of soup are suitable for canning without a pressure cooker?
Soups that are high in acidity and low in fat are the most suitable for canning without a pressure cooker. Tomato-based soups, vegetable soups with added acidic ingredients, and broth-based soups that do not contain meat are good candidates. These types of soups help ensure that the proper temperatures are reached during the water bath canning process, making them safe for long-term storage.
When preparing your soup for canning, ensure that you follow reliable recipes that adhere to recommended acidity levels and ingredients. This ensures that the soup is not only delicious but also safe for consumption after being canned.
How long will canned soup last?
Canned soup can last for a significant duration if properly processed and stored. Generally, if you follow the correct canning procedures, your soup can last from 1 to 5 years. However, it’s crucial to store canned goods in a cool, dark place, such as a pantry or cellar, to maximize shelf life and preserve flavor and nutrition.
Always check for signs of spoilage before consuming canned soup, such as bulging lids, off colors, or foul odors. If any of these signs are present, it’s best to discard the jar to avoid any health risks.
What safety precautions should I take when canning soup?
Safety is paramount when canning soup, especially when using a water bath method. Always ensure that your jars are sterilized and in good condition, without any cracks or chips. Cleanliness is critical, so wash hands, utensils, and work surfaces before starting the canning process. Use fresh ingredients and avoid any that may have been left out too long or show signs of spoilage.
Additionally, be mindful of altitude adjustments when determining the processing time. High altitudes require longer processing times to ensure safety and seal integrity. Following USDA guidelines and using tested recipes can help you navigate these precautions effectively.
Can I reuse canning jars and lids?
You can definitely reuse canning jars as long as they are in good condition. Check for any cracks, chips, or rusts before using them. However, it’s important to note that while you can reuse jars, you should not reuse the lids. Canning lids are designed for a single use since their sealing compound can lose effectiveness after one use, leading to potential spoilage and failure to create a proper seal.
When reusing jars, always wash them thoroughly and sterilize them before filling with soup. This ensures that they are free from bacteria or residues from previous use, contributing to the safety and quality of your canned products.
How do I know if my canned soup has sealed properly?
To check if your canned soup has sealed properly, you can perform a simple test: press down on the center of the lid. If the lid flexes up and down, the jar has not sealed properly, and the contents could be at risk of spoilage. A properly sealed lid will remain flat and will not budge when pressed. Additionally, you can inspect the lid for any bulging or signs that it may have popped during storage, which could also indicate a failed seal.
After the jars have cooled, it’s also a good idea to check the seals by storing them in a cool, dark location for a few days. If they remain sealed and show no signs of spoilage, your canned soup is ready for long-term storage. If you find any failed seals, consume the contents immediately or refrigerate for short-term use.
