Tomato Soup Concentrate for Canning

September 1, 2016

Having a stash of homemade tomato soup concentrate in your pantry is like doing a favor for your future self. Portioning it out in 26 ounce jars from Fillmore Container makes it look extra snazzy!

My tomato preservation approach is one that is forever evolving. I make a point of trying at least one new-to-me tomato recipe to each season, always hoping that I’ll discover something particularly delicious and worthy of my time, resources, and shelf space.

This year, there were two experimental recipes. The first was this barbecue sauce (which is quite delicious, but probably won’t be something I make every single year). The second is the tomato soup concentrate that I’m sharing today. I’m already hoping that when I get home from the trip I’m currently on (I’ve been away for a week, which accounts for the blog silence), I’ll be able to get enough tomatoes to make another batch.

Recipes for tomato soup concentrates that are safe for the boiling water bath canner aren’t always easy to find. I did a lot of reading and worked out more math problems than is typically required for a basic canning recipe in order to bring this to you today. I built my recipe upon the framework laid out in the National Center for Home Food Preservation’s water bath safe Tomato and Vegetable Juice recipe.

The thing in that recipe that made everyone here possible is the fact that it specifies that, “Not more than 3 cups of other vegetables may be added for each 22 pounds of tomatoes.” Taking my cue from there, I used 15 pounds of tomatoes, and a scant two cups of diced onions. I felt comfortable doing that, because I was keeping to their approach while reducing the batch size by one-third.

From there, it was a matter of chopping the tomatoes and cooking them down with the onion. Once they were soft, I pushed them through a food mill fitted with its finest screen. At that point, I had approximately 24 cups of flavorful tomato juice.

I added Italian seasoning and granulated garlic, and cooked it down until I had a thick, tasty 16 cups. Once I was finished cooking, I added salt to taste (it’s always best to wait until you’ve finished cooking something down before salting it. Otherwise, you can end up with something inedible).

Then I portioned 1/2 teaspoon of citric acid into five square sided 26 ounce jars from Fillmore Container and filled them up with my soup concentrate. I added five minutes to the processing time required by the NCHFP for the tomato and vegetable juice, to compensate for the increased thickness.

I love canning tomato products in these square sided jars because they give it a more professional look, and I find that the squared off sides make them easier to grab when I’m moving quickly. The 26 ounce size is also great from a portioning perspective. Reheated with a bit of milk, there’s just the right amount for two people to enjoy bigs bowls with a side of cheesy toast or garlic bread.

Oh, and if you find yourself liking the looks of the square shape, know that they’re also available in 8 ounce and 16 ounce sizes.

Tomato Soup Concentrate

Yield: Makes approximately 16 cups of product

Ingredients

  • 15 pounds of tomatoes
  • 2 cups diced onion
  • 2 tablespoons granulated garlic
  • 1 tablespoon dried Italian seasoning
  • 1 tablespoon salt, plus more to taste
  • 2 1/2 teaspoons citric acid

Instructions

  1. Wash the tomatoes and cut them into quarters. Heap the chopped tomatoes into a large pot and add the diced onion.
  2. Add about a cup of water to the bottom of the pot to prevent scorching. Place the pot on the stove and bring it to a boil.
  3. Cook, stirring occasionally for about an hour, until the tomatoes have lost their structural integrity and the pot contains nothing but super saucy tomatoes.
  4. Remove the pot from the stove. Fit a food mill with its finest screen and position it over a large heatproof bowl.
  5. Working in batches, start pushing the cooked tomatoes and onions through the food mill. You will probably need to stop three or four times to empty out the bowl into a clean pot.
  6. Once all the tomatoes are milled, add the granulated garlic and Italian seasoning. Set the pot on the stove and bring to a low boil.
  7. Cook for one to three hours, until the soup concentrate has reduced by at 1/3 and hopefully a bit more.
  8. When you're pleased with the consistency, stir in the salt. Start with a tablespoon. Taste and add more as needed.
  9. Divide the citric acid between five jars 26 ounce jars (the Ball brand 24 ounce Pint & Half jars are also a great choice for this one).
  10. Funnel the finished soup concentrate into the jars, leaving 1/2 inch headspace.
  11. Wipe the rims, apply the lids and rings, and process in a boiling water bath canner for 45 minutes (if you live above 1,000 feet in elevation, please adjust your processing times accordingly).
  12. When the time is up, remove the jars and set them on a folded kitchen towel to cool. When the jars have cooled enough that you can comfortable handle them, check the seals. Sealed jars can be stored at room temperature for up to a year. Any unsealed jars should be refrigerated and used promptly.

  1. Apricots…they exude the warmth of summer…add cinnamon, cloves, and ginger…drizzle over fresh-from-the-oven gingerbread and extend summer into winter!

  2. I love Tomato soup and grilled cheese sandwiches. Especially in the winter. I would love to win a case of this fabulous soup.

  3. I`ve canned jellies and jams and can always use some more jars . I might even try their tomato soup recipe if I get them extra jars .

  4. I truly love home made tomato soup, no store purchased brand can take claim to fame over any thing from a home cooked, jarred up food!

  5. My favorite homemade preserve in January is strawberry jam (actually any month when it isn’t strawberry season).

  6. I’m still pretty new to canning, so I didnt realize I could do tomatoes in a water bath. I want to try this recipe for sure!

  7. My new fave is your tomato jam recipe from a few years ago! Have nearly 30 small jars stashed away for this winter.

  8. tonight’s recipe is Italian Drunken Noodles using a jar of canned San Marzano tomatoes from my neighbor’s garden.

  9. Nowadays, I usually just keep preserving simple and put up plain ingredients like plain tomatoes or frozen strawberries. Then, in the winter, when I have TIME to cook, I can grab them and make fresh-tasting, healthy meals and experiment with small-batch recipes. However, I do have a salsa recipe that I can and am always glad to be able to grab a jar of that!

  10. Michigan winters can be cold and dark – a jar of sweet pickles always makes me happy when the snow is deep outside. They remind me of picnics, green grass, and sunshine.

  11. Requests for our Camp Aranzazu Hot Sauce were under such popular demand that we mass produced the product for table favors during our last ZAZU Fishing Tournament fund raiser. To our surprise, the product was so well received, our kitchen staff was asked to make a second batch to be used for Christmas gifts….

  12. My favorite is blueberry jam. This post brought back memories of my moms jarred peaches. I don’t remember why I has carrying a jar around the house but I wasn’t supposed to be in my brothers room when I dropped it and the jar shattered. There was peaches and juice everywhere. He was so mad when he got home and his room smelled like peaches.

  13. Going to try this recipe. When january comes around, there is nothing better than homemade tomato soup with a side of grilled cheese.
