recipe for canning tomato basil soup

Canning your own tomato basil soup is a rewarding experience, offering a taste of summer all year round. This comprehensive guide will walk you through the process, ensuring safe and delicious results. We'll cover everything from ingredient selection to proper sterilization, guaranteeing your canned soup is both flavorful and shelf-stable.

What You'll Need:

Ingredients:

  • 6 pounds ripe tomatoes, peeled and chopped (Roma or heirloom varieties work well)
  • 1 large onion, chopped
  • 4 cloves garlic, minced
  • 1 cup fresh basil leaves, roughly chopped
  • 2 tablespoons olive oil
  • 1 teaspoon dried oregano
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon red pepper flakes (optional, for a touch of heat)
  • 1/2 cup vegetable broth or water (adjust to desired consistency)

Equipment:

  • Large stockpot
  • Immersion blender or regular blender
  • Canning jars (pint-sized are ideal)
  • Lids and bands for canning jars
  • Jar lifter
  • Large canning pot with rack
  • Bubble remover tool
  • Magnetic lid lifter
  • Kitchen towel

Step-by-Step Canning Process:

1. Prepare the Tomatoes:

Start by preparing your tomatoes. Wash them thoroughly, then blanch them briefly in boiling water to easily remove the skins. This makes for a smoother soup. Chop the peeled tomatoes.

2. Sauté Aromatics:

In your large stockpot, heat the olive oil over medium heat. Add the chopped onion and sauté until softened, about 5 minutes. Stir in the minced garlic and cook for another minute until fragrant.

3. Simmer the Soup:

Add the chopped tomatoes, basil, oregano, salt, pepper, and red pepper flakes (if using) to the pot. Stir well to combine. Bring the mixture to a simmer, then reduce heat and cook for at least 20 minutes, stirring occasionally, allowing the flavors to meld.

4. Blend the Soup:

Carefully use an immersion blender to puree the soup until smooth. Alternatively, you can carefully transfer the soup in batches to a regular blender and puree until smooth. Be cautious when blending hot liquids.

5. Adjust Consistency:

If your soup is too thick, add the vegetable broth or water, a little at a time, until you reach your desired consistency.

6. Sterilize Jars and Lids:

While the soup simmers, sterilize your canning jars, lids, and bands. Place jars in a large pot of boiling water for at least 10 minutes. Boil lids in a separate saucepan for about 5 minutes.

7. Fill the Jars:

Carefully ladle the hot soup into the sterilized jars, leaving about 1/2 inch headspace at the top. Use a bubble remover tool to eliminate any air bubbles. Wipe the rims of the jars clean with a damp cloth.

8. Seal the Jars:

Place the lids on the jars and screw on the bands fingertip tight. Do not over-tighten.

9. Process in a Water Bath:

Place the filled jars in your canning pot with the rack, ensuring they are covered by at least 1-2 inches of water. Bring the water to a rolling boil and process the jars for 35 minutes (for pint jars) at a consistent boil. Adjust processing time according to your altitude. Refer to a reliable canning resource for altitude adjustments.

10. Cool and Check Seals:

Once the processing time is complete, carefully remove the jars from the canner using a jar lifter and let them cool completely undisturbed for at least 12-24 hours. You should hear a "pop" sound as the jars seal. Check the seals by pressing down on the center of each lid; if it doesn't flex, it's sealed.

Troubleshooting and FAQs

How long will canned tomato basil soup last?

Properly canned tomato basil soup, stored in a cool, dark, and dry place, can last for 12-18 months.

What if my jars didn't seal?

If a jar didn't seal, it's crucial to refrigerate it and consume it within a few days. Do not attempt to re-can it.

Can I use frozen tomatoes?

While fresh tomatoes are ideal, you can use high-quality frozen tomatoes. Just make sure they are thawed completely before adding them to the pot.

Can I add other vegetables?

Absolutely! Feel free to experiment with adding other vegetables like carrots, celery, or zucchini.

What are the safety precautions I need to take when canning?

Always follow tested recipes and procedures. Use a reliable canning resource for your specific altitude. Ensure jars and lids are properly sterilized. Pay close attention to processing times. Never reuse jars that have previously failed to seal.

This guide provides a comprehensive approach to canning tomato basil soup. Remember, safety is paramount, so always refer to a reputable canning resource for detailed instructions and adjustments based on your altitude. Enjoy your delicious homemade soup throughout the year!
