Homemade Canned Tomato Soup Recipe

This homemade canned tomato soup recipe is for the folks who loved my previous tomato soup recipe but wanted one that could be canned.

When I shared my husband’s favorite homemade tomato soup recipe a while back, many of you asked if it could be canned.

Unfortunately, making a homemade canned tomato soup is a bit more complicated than throwing any tasty recipe in jars and sending them through the canner. So, I set out to find another tomato soup recipe that my husband would love. This time, it needed to be canning friendly.

Homemade Canned Tomato Soup: A Few Rules

The tricky thing about making canned tomato soup is that many recipes use ingredients like flour as a thickener or cream for added texture and flavor. Neither of these can be safely canned, even with a pressure canner.

The other thing about making it for canning is that you need to use an acid.

When you can tomato soup, you have to make sure the acid level is high enough that it will be shelf-stable. But you also don’t want that acid level to affect the soup.

When canning tomatoes, The National Center for Home Food Preservation advises that you use no more than 3 cups of vegetables for every 22 lbs of tomatoes. If you add too many vegetables, you dilute the natural acid from the tomatoes, and your soup is no longer able to be canned.

Sticking to this advised ratio, I added most of my flavorings for this soup in the way of dried herbs and spices.

How To Make Tomato Soup For Canning

Once you have a good recipe, made for putting in jars, the process is pretty straightforward:

  • cook vegetables until very soft
  • puree the vegetables
  • season the soup
  • reduce the soup
  • can it!

I used a high powered blender to puree our cooked tomatoes and onion. There were only a few small tomato bits left after blending so I didn’t bother straining my soup.

If you have a blender that doesn’t sufficiently chop up tomato skins, you might want to strain the soup before seasoning and reducing it. Alternatively, use a food mill to puree the tomatoes and get rid of the skins.

What Tomatoes Should I Use?

The best tomatoes to use are “paste” tomatoes. These are tomatoes that have thicker, meatier walls and contain less water.

This means there will be more tomato and less juice, and the soup will thicken up faster, which is important because thickeners can not be used in homemade canned tomato soup.

Probably the most commonly known “paste” tomato is the Roma tomato. These little tomatoes have great flavor and work wonderfully for making homemade tomato soup.

Adding Acid For Canning

As I mentioned, acid is incredibly important in making sure your homemade canned tomato soup will stay shelf-stable.

To really make sure the acid level is right, it is common to add lemon juice or citric acid to the jars when you are canning anything tomato related.

You might be worried that lemon juice would affect the flavor of the soup. It does, but only slightly. And your soup won’t taste lemony at all. Rather, it just tastes slightly brighter.

Citric acid doesn’t alter the flavor of the soup at all. So if you’re concerned about the lemon flavor, use citric acid.

However, there is another factor. When you add milk to the tomato soup that had citric acid in it, the milk separated a little. When added to the soup that had lemon juice, the milk separation was barely noticeable.

I’d rather have a slightly brighter soup with less milk separation. Choose which route is best for your tastes!

Serving Homemade Canned Tomato Soup

Keep in mind that you are making a slightly condensed tomato soup. The finished soup should be slightly thicker than you like to serve it, particularly if you like to add cream or milk to it.

Finally, to serve the canned tomato soup, simply pop open the jar, pour it into a bowl or saucepan, add as much milk or cream as you desire, and reheat.

It’s so easy, and it’s a great way to have a quick lunch or dinner ready in no time. This is the perfect way to preserve your summer tomatoes so you can enjoy them all winter long! (And you skip all the extra salt and additives in the store-bought cans of tomato soup!)

  1. Quarter tomatoes and dice the onion. Place them in a large soup pot along with ½ cup of water. Cook, uncovered, for 30 min – 1 hour, stirring occasionally, until tomatoes are very soft.
  2. Remove tomatoes from the heat and let them cool slightly. Working in batches, transfer the warm tomatoes to a food processor, blender, or food mill to puree. If desired, press the tomato puree through a fine-mesh sieve to remove any seeds and skins.

  3. Pour the smooth tomato puree back into the large soup pot. (Using a very wide-bottomed pot will give you more surface area as you reduce tomatoes, making the process take less time.)

  4. Add the tomato paste, sugar, herbs, and spices. (Everything EXCEPT the lemon juice or citric acid.)
  5. Bring seasoned tomato puree to a simmer. Cook tomato soup until it has reduced to the thickness you desire. (Mine took 1 hour of simmering.)
  6. While the soup is simmering, wash canning jars and keep them warm. Prepare the water bath canner.
  7. When the soup has reached the desired thickness, taste it and adjust salt as desired.
  8. Add 1 Tbsp of lemon juice to each pint jar or 2 Tbsp lemon juice to each quart jar. (Or ¼ tsp citric acid to each pint and ½ tsp citric acid to each quart.)
  9. Fill jars with the soup, leaving ½ inch of headspace. (I like to use a canning funnel to reduce spills and messes.)

  10. Wipe the rims clean of any spilled soup. Then cover the jars with fresh lids and rings.

  11. Process your canned tomato soup in a boiling water bath canner for 40 minutes for pints or quarts. (Adjust the processing time as needed for your altitude.)

  12. After processing, carefully remove the jars from the water and set them on a cooling rack.
  13. Once the jars and soup have cooled, remove the rings and check that your lids have sealed.
  14. Finally, store the sealed jars in a cool place for up to a year. If any jars didn’t seal properly, refrigerate them immediately and eat within a week.

The amount of soup you end up with will depend on the type of tomatoes used and how much you reduce the soup.  The type of tomatoes used (how much water they contain) will also determine how long the soup needs to cook to reduce down to your preferred consistency.

To Serve

Reheat your canned tomato soup with some milk or cream, as desired.

    I do not take a chance canning the f8nnished soup. I par boil the tomatoes then put it through my antique cone sieve. Keep all the tomato pulp, throw away the skins.
    Then I cook my soup base at a simmer to reduce slightly. I add oregano, basil, salt and pepper plus two tablespoons of sugar.
    When it is reduced enough, it all depends on what you want, I add one tablespoon of lime juice to each jar, add soup and put on tops and rings. Make sure to clean the jars first of any spilt soup base(best done with clean paper towel) then 35 minutes into my canning pot. Let them cool and shelve them. When you want soup you have a good base already.

  2. Patty says

    Love this recipe! I add a touch of cayenne for a little zing. My daughter went off to college this summer and took all of my stash with her. Time to make more!

  3. Suzy says

    Whoops! I forgot to put the lemon juice in the jars. They are already in the boiling water bath. Is all lost? Or will they be fine? Thanks! I made this last year and it is hands-down my husband’s favorite tomato soup!

    • Shari says

      You HAVE to have the lemon juice or citric acid in the jars! Just dump them all back into a pot, re-heat, then complete the process (using new seals).

      • Suzy says

        Or else what? I would think the tomatoes are acidic enough? And they’ve already been sitting almost 24 hours. Maybe Sarah or Matt could chime in.

        • Sarah Ozimek says

          Hi Suzy. Different tomatoes have different levels of acidity. Some would be fine, other may not be. Without pH testing your soup, it’s impossible to know if it falls within the ‘safe’ levels for home canning. That being said, if I were in your shoes, I would likely leave it and just make a note to use the soup sooner rather than later. (Definitely no loner than 6 months on the shelf.) I would really pay attention to look and smell when I open the jars, and heat to a good boil before eating. But, that’s just what I would do for myself, and not a recommendation I can give, since this is definitely a ‘use at your own risk’ situation, since it does vary from safe canning guidelines.

          • Suzy says

            THANK YOU Sarah! I’ve been canning tomatoes for over 40 years and never added lemon juice to the jars. One year I processed and canned just over 100 quarts of tomato sauce (it was a personal best!) 😉 I had never made tomato soup, and this recipe is the best, so really enjoy making it. I’m pretty sure I forgot the lemon juice last year when I made it. No issues. I always smell anything I open after canning, and give it a good looking over. I’ll use these jars first; I’m sure it’s safe. As a side note: I still have my mother’s old Kerr canning recipe book. It tells you how many HUNDREDS OF MINUTES to process meat in a water canner! She did green beans and everything. Never used a pressure canner. No one ever got ill. But she also showed me the fine art of making sure everything was clean. You could have done surgery in her kitchen when she was canning! haha!! Thanks for the response!! Happy Canning!!

  4. Becky says

    Thank you for the recipe. Is it possible to still be shelf stable without the brown sugar?

  5. Rosemary Hanning Warner says

    This soup is amazing! I used my Black Krim tomatoes – what a tasty soup for a cold winter day. Planning on canning more of this recipe. I didn’t put the bay leaves in the first batch but will try it on the next batch. Thank you so much for this really great tomato soup recipe!

  6. Isabella says

    Instead of using milk, could I use almond milk or cream? Or could I even leave that out and just add it when I reheat it?

    • ML says

      Not the person who posted, but the milk shouldn’t be added until after reheating, milk products are not safe to home can so you can add it when you open the jar to heat it up and eat it, if you prefer it and honestly that’s completely up to your taste.

  7. Susie says

    Going to be trying out this recipe as have an abundance of a mixed variety of tomatoes that voluntarily grew in my garden this year. Instead of using milk, could I use coconut milk or cream? Or could I even leave that out and just add it when I reheat it?

  8. Catherine Hinkle says

    This is not a safe recipe unless you peel the tomatoes. Washing them does not reduce the bacterial load enough to be safe from botulism. Please go to the National Center for Home Food Preservation and look up “canning tomatoes.”

  9. carolym says

    Just an f.y.i….. Ball and other sources say to not store canned foods with rings on. Compromised/failed lids have the potential of reseating themselves if the ring is left on. It would then be dangerous to consume the contents. If stacking jars ( no more then 1 high is recommended) , be sure to put something like a piece of cardboard on top of the lower level to distribute the weight to avoid not being able to not discover any seals that popped.

  10. Kat says

    Thanks for posting! Two questions: I’m not a fan of adding cream/milk to tomato soup so would I cook it down to the consistency I want the final product to be or would I thicken it more and plan to add water or stock to thin when I reheat (or does it matter?). Second – there’s a fantastic red pepper/tomato soup in a carton on the market. Do you have a recipe for something like that? Preferably without added sugar? I tend to use ground carrots in my tomato sauces to avoid adding sugar to balance. Thanks!

    • Matt Jabs says

      Hi Laura! Step 8 says, “Add 1 Tbsp of lemon juice to each pint jar or 2 Tbsp lemon juice to each quart jar. (Or ¼ tsp citric acid to each pint and ½ tsp citric acid to each quart.)”

    • Sarah Ozimek says

      Hi Laura. You add the lemon juice in step #8 to the individual jars. Add 1 Tbsp of lemon juice to each pint jar or 2 Tbsp lemon juice to each quart jar. Enjoy!

  11. Lynne Ham says

    Got one batch finished while baking and other stuff. Visiting my grandson tomorrow. Meemee has treats will travel lol. Anyway, this recipe made my kitchen smell amazing! It tastes like dining in an expensive Italian restaurant! Will make another batch later…my feet are swollen lol. I highly recommend this recipe🍅

  12. Lynne Ham says

    I couldn’t find “granulated” garlic. Will minced garlic be ok, and if so, how much?

      • Sarah Ozimek says

        Hi Lynne and Sue. I choose granulated garlic for this recipe because it can be tricky to safely can fresh garlic unless you are pickling it using a high amount of vinegar. Since I can’t guarantee that the acid levels of this soup will be high enough to safely can the garlic, I can’t recommend the use of fresh garlic in this recipe. If you can’t find minced garlic, garlic powder would be my next recommendation (at the same amount as the granulated). Using an already dehydrated form of garlic is the only way to ensure you have a safe canning environment with regards to the garlic in this recipe. Enjoy!

  13. Beth says

    I made a variation of this recipe, I only used tomato’s roasted fresh with onion and garlic roasted with them. I puréed it, strained and heated but didn’t add the lemon juice or citric acid. I did mix some ricotta cheese in when heating to a boil on the stove. Canned 25 mins. Will the cheese effect the acidity to where it’s not shelf stable without the added acid. Great recipe!! This is my first time canning in years so I’m a bit rusty

    • Sarah Ozimek says

      Hi Beth. I would NOT trust your variation of the soup to be shelf stable. First, the added acid is an important element in being sure the acidity is high enough to keep this soup safe on the shelf. Secondly. it is not recommended to can anything with dairy in it because of the fat. If you like ricotta in your tomato soup (and that sounds quite tasty), I would recommend adding it before serving the soup, rather than for canning.

      The soup that you just made, I would recommend freezing, if you made enough that you would like to save it for later.

    • Sarah Ozimek says

      Hi Marlene,
      I’m not familiar with using a pressure canner. But, I would follow the same process that you would for canning tomatoes.
