Tomato soup is a comforting and delicious dish cherished by many. It’s not just a perfect meal during cold weather; it’s also an excellent option for meal prep and preservation. While pressure cookers can make the process easier and faster, they are not the only tools available for canning tomato soup. This guide will walk you through how to can tomato soup without a pressure cooker, showcasing the steps, best practices, and tips to ensure your soup remains safe, delicious, and nutritious.
Understanding the Basics of Canning
Before diving into the specifics of canning tomato soup, it’s essential to understand what canning entails. Canning is a method of preserving food by sealing it in airtight containers, typically glass jars, to prevent the growth of bacteria, yeasts, and molds. This process not only extends the shelf life of your food but also locks in flavors and nutrients.
Why Canning Tomato Soup?
Canning your tomato soup is beneficial for several reasons:
- Preservation: Canning extends the shelf life of your tomato soup for up to a year or longer when stored correctly.
- Convenience: Having homemade soup on hand makes meal preparation quick and easy, especially on busy days.
- Customization: You can control the ingredients, making it healthier and fresher compared to store-bought options.
- Sustainability: Canning allows you to utilize seasonal produce and reduce food waste.
Ingredients for Your Tomato Soup
To create a delightful homemade tomato soup, you will need a few core ingredients. Here’s a basic list:
- Fresh tomatoes (about 5-6 pounds for a large batch)
- Onion (1 medium-sized, diced)
- Garlic (3-4 cloves, minced)
- Basil (fresh or dried, to taste)
- Olive oil (2 tablespoons)
- Salt (to taste)
- Black pepper (to taste)
- Vegetable or chicken broth (4 cups)
- Sugar (optional, to balance acidity)
Feel free to add other herbs or spices to suit your taste preference.
Gather Required Equipment
To can tomato soup without a pressure cooker, you will need certain equipment to ensure the process is efficient and safe. Here’s what you’ll need:
- Large pot for cooking the soup
- Sterilized glass jars (quart or pint-sized)
- Jar lids and bands
- Ladle
- Canning funnel (optional, but helpful)
- Kitchen towels
- Large pot for water bath canning
- Food processor or immersion blender (for smooth soup)
Make sure all your equipment is clean and sanitized before use to prevent contamination.
Making the Tomato Soup
Now let’s move on to the step-by-step process of making your tomato soup.
Step 1: Prepare Your Tomatoes
To start, you’ll want to prepare your tomatoes. Here’s how you can do this effectively:
- Wash the tomatoes thoroughly to remove any dirt or pesticides.
- Core and cut the tomatoes into quarters.
- If you prefer a smoother soup, consider peeling the tomatoes. You can do this by blanching them: simmer for 2-3 minutes, remove, and plunge into ice water.
Step 2: Cook the Soup
In a large pot over medium heat, add olive oil. Once hot, add the diced onions and minced garlic. Sauté until the onions are translucent, about 5 minutes.
Next, add the prepared tomatoes and sauté for an additional 10-15 minutes. This process allows the flavors to meld and enhances the taste of the soup.
Now, add the broth, basil, salt, and pepper. If you’d like, stir in a bit of sugar to cut down on the acidity of the tomatoes.
Bring the mixture to a simmer and cook for about 30-40 minutes, stirring occasionally.
Step 3: Blend the Soup
If you prefer a smooth texture, you can use a food processor or an immersion blender to puree the soup to your desired consistency. If you’re using a standard blender, do this in batches; just be cautious to avoid burns.
Many people prefer a chunky soup, so if that’s your style, you can skip blending and leave the soup as is.
Canning the Tomato Soup Using the Water Bath Method
Now that your soup is made, it’s time to can it. We will be using the water bath method, as it’s safe for high-acid foods like tomato soup.
Step 1: Prepare Your Jars
Ensure all jars are sterilized before use. You can do this by placing your jars in a pot of boiling water for about 10 minutes, or running them through a dishwasher cycle on hot.
Step 2: Fill the Jars
Using a ladle or canning funnel, pour the hot tomato soup into the sterilized jars, leaving about 1 inch of headspace at the top. This space is crucial for a proper seal.
Make sure to wipe any residue from the rims of the jars with a clean kitchen towel to ensure a good seal.
Step 3: Seal the Jars
Place the lids on the jars, ensuring they’re centered over the rims. Then, screw on the bands until they are fingertip-tight, which means they should be snug but not overly tight.
Step 4: Process the Jars
Carefully place the filled jars into a large pot of boiling water, ensuring water covers the jars by at least 1 inch. The water should remain at a rolling boil for the entire processing time.
Process for approximately 35 minutes for pint-sized jars and 45 minutes for quart-sized jars. Adjust the time if you’re at higher altitudes.
Step 5: Cool and Store the Jars
Once the processing time is complete, carefully remove the jars using canning tongs and place them on a clean kitchen towel or cooling rack. Allow them to cool completely for 12-24 hours.
You might hear a popping sound as the jars seal. After cooling, check that the lids have sealed properly. They should not flex up and down when pressed.
Storing Your Canned Tomato Soup
Once the jars have cooled and sealed, label them with the date and contents and store them in a cool, dark place, such as a pantry or cupboard. Properly canned tomato soup can last for up to a year, but for the best quality, consume it within six months.
Tips for Successful Canning
To make sure your canning experience is smooth and the results are delicious, here are some tips:
- Always use fresh, ripe tomatoes: This ensures the best flavor and texture for your soup.
- Adjust seasoning carefully: Taste as you go, but remember that flavors will deepen slightly during the canning process.
- Stay organized: Keep your workspace tidy and organized to make the process easier.
- Monitor the water level: Make sure the water in the canning pot stays at a steady boil and covers the jars as required.

Using water bath canning requires you to boil jars of soup in a water-filled canner for a specified period. Make sure to adhere to a reliable recipe that accounts for the acidity levels; if you’re unsure, you can always add lemon juice or citric acid to boost acidity and ensure safety during the canning process.
How long can I store canned tomato soup?
Canned tomato soup can typically be stored for up to one year when stored in a cool, dark place. While the soup may remain safe to eat beyond this timeframe, its flavor and quality may decline over time. To ensure you enjoy the best taste, try to use your canned products within a year, taking note of the canning date.
When storing your canned soup, inspect the jars for any signs of spoilage, such as leaks, bulging lids, or unusual odors. If any of these signs are present, it is best to err on the side of caution and dispose of the jar instead of consuming it.
What equipment do I need for canning tomato soup?
For canning tomato soup, you will need essential equipment that includes a large pot for cooking the soup, a water bath canner or a large pot with a lid for the actual canning process, and canning jars with two-part lids. Other useful tools include a jar lifter, a funnel, and a ladle to make the filling process easier and more precise.
Additionally, you might want to have a food processor on hand if you prefer a smoother soup texture. Thermometers can help ensure that your soup has reached the right temperature, and a timer is essential to track the recommended processing time accurately.
How do I prepare the tomatoes for canning?
To prepare tomatoes for canning, start by washing them thoroughly to remove any dirt or residues. You can then peel them by blanching in boiling water for about 30 seconds, followed by placing them in an ice bath. The skins will loosen, making them easy to peel off. Once peeled, chop the tomatoes into quarters or smaller pieces, depending on your desired texture for the soup.
After preparing the tomatoes, combine them with your chosen vegetables and seasonings in a large pot. Cook the mixture over medium heat until the tomatoes break down and the flavors meld, stirring often to prevent sticking. This mixture will make the base for your soup before it gets canned.
Can I add other ingredients to the tomato soup?
Yes, you can definitely add other ingredients to your tomato soup to enhance its flavor and nutritional value. Many people like to include additional vegetables, such as carrots, celery, or zucchini. You can also experiment with various herbs and spices to customize the soup to your taste. Fresh herbs like basil and parsley can make the soup more aromatic, while dried herbs add richness over time.
However, be cautious about adding ingredients that may affect the soup’s acidity. Ingredients like grains or flour can change the pH level, which is crucial for safe canning. Stick to ingredients that complement the soup and maintain its acidity for food safety purposes.
How do I know if my canned tomato soup is safe to eat?
To ensure that your canned tomato soup is safe to eat, always inspect the jars before opening them. Check for any signs of spoilage, such as leaks, bulging lids, or a bulged seal around the lid. If the lid does not pop when opened, or if the soup has an unusual odor or appearance, do not consume it.
After opening, if the soup looks and smells normal, you can reheat it and taste a small amount. Always store opened jars in the refrigerator and consume the contents within a few days. When in doubt about the safety of your canned food, it is better to discard it than take any risks with your health.
