Instructions
- Prep Vegetables. Chop the onions and celery. Place them in a large kettle with just enough water to prevent burning. Simmer gently.
- Prepare Tomatoes. While the vegetables are simmering, cut the tomatoes, removing stems if not using a strainer. Add them to the kettle and cook until tender.
- Strain Mixture. Pass the cooked vegetables and tomatoes through a Victorio strainer (or similar) to remove skins and seeds. Return the strained mixture to the kettle.
- Add Flavors. Stir in the sugar, salt, and optional herbs (basil, oregano, bay leaves) into the mixture.
- Make Roux. In a separate bowl, cream the butter and flour together. Mix thoroughly with two cups of COLD juice until dissolved (to avoid lumps). Add this roux to the warmed tomato mixture before it gets hot, stirring well.
- Heat. Warm the mixture just until hot, avoiding a boil to prevent flour lumps. The mixture will continue to thicken as it cools.
- Fill jars. Ladle the hot soup concentrate into hot canning jars, leaving 1 inch headspace. Remove air bubbles, wipe rims, and secure lids and bands.
- Pressure can. Process pint jars in a pressure canner at 10 pounds of pressure for 15 minutes, adjusting for altitude. Check your pressure canner's manual for quart jars and for adjustments based on your location.
- Cool. After processing, turn off the heat and let the canner depressurize. Remove jars and let them cool undisturbed for 12-24 hours. Check seals before storing in a cool, dark place.

Trust me, once you try it, you’ll want to keep your pantry stocked all season long!
Key Ingredients and Tools
Here’s a brief look at some important ingredients and why they matter:
- Pressure Canner. Essential for safe canning and preserving the soup at home, a pressure canner is different from a water bath canner and is specifically needed for low-acid foods like vegetables.
- Food Mill. This tool helps in smoothly processing tomatoes and vegetables by removing skins and seeds, ensuring a silky texture in your concentrate.
- Victorio Strainer. Similar to a food mill, this specialized tool can speed up the straining process and is excellent for larger batches. It’s particularly useful if you make preserves often.
- Roux (Butter and Flour). This mixture thickens the soup concentrate. It’s crucial to mix it to a smooth, lump-free consistency with cold juice before adding it to the hot tomato base to prevent clumping.
Troubleshooting and Help
Absolutely! If fresh tomatoes aren’t in season or if you’re looking for a quicker option, canned tomatoes are a great substitute. Just be sure to use high-quality canned tomatoes for the best flavor.
No worries! You can peel and seed the tomatoes manually before cooking, though it’s a bit more labor-intensive. After cooking, you could use a blender or a sieve to help strain out any remaining skins and seeds.
Yes, for safety reasons, a pressure canner is necessary when canning this tomato soup concentrate. The pressure canner helps to eliminate the risk of bacteria, like botulinum, which can thrive in low-acid environments like tomato soup.
When properly canned and stored in a cool, dark place, your tomato soup concentrate can last for up to a year. Always check the seal and look for any signs of spoilage before using.
Definitely! If you prefer not to can, you can freeze the soup concentrate. Just be sure to leave some headspace in the containers when you fill them, as the liquid will expand when frozen. It should keep well for several months in the freezer.
