Homemade Canned Tomato Soup Recipe
Ingredients
- 7 lbtomatoes)
(romas work well
- 1 cyellow onion)
(diced
- ½ cfiltered water
- 3 tbsptomato paste
- 3 tbspbrown sugar
- 1 tbspdried oregano
- 2 tspdried basil
- 2bay leaves
- 2 tspgranulated garlic
- 1 ½ tspsalt
- 1 tspcelery seed
- ½ tspblack pepper
- lemon juice or citric acid
Directions
- 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.
