Making your own canned tomato soup is a rewarding experience, offering the delicious taste of fresh tomatoes preserved for enjoyment throughout the year. This guide covers everything from selecting the right tomatoes to ensuring safe canning practices, helping you create a pantry staple you'll be proud of.
What Kind of Tomatoes Are Best for Canning Tomato Soup?
The best tomatoes for canning soup are those with a high flesh-to-seed ratio and a rich, flavorful taste. Roma tomatoes, also known as plum tomatoes, are a popular choice due to their low water content and meaty texture. However, you can successfully use other varieties like heirloom tomatoes, provided you adjust the cooking time to account for variations in water content. Avoid using overly watery or green tomatoes, as these will yield a less flavorful and less visually appealing soup.
How to Make Homemade Tomato Soup for Canning?
This recipe produces approximately 7 pints of delicious homemade tomato soup. Adjust quantities as needed.
Ingredients:
- 12 pounds ripe tomatoes (Roma tomatoes recommended)
- 1 large onion, chopped
- 2 cloves garlic, minced
- 2 tablespoons olive oil
- 1 teaspoon dried basil
- 1 teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 cup vegetable broth (or chicken broth for richer flavor)
- Optional: 1/4 cup heavy cream or milk for a creamier texture (add after canning)
Instructions:
- Prepare the Tomatoes: Wash and roughly chop the tomatoes.
- Sauté Aromatics: Heat olive oil in a large pot over medium heat. Add the chopped onion and sauté until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant.
- Simmer Tomatoes: Add the chopped tomatoes, basil, oregano, salt, and pepper to the pot. Bring to a simmer, reduce heat, and cook for at least 30 minutes, or until the tomatoes have softened and broken down. Stir occasionally to prevent sticking.
- Blend (Optional): For a smoother soup, use an immersion blender to puree the mixture directly in the pot. Alternatively, carefully transfer the mixture to a regular blender in batches (be cautious of hot liquids!), and blend until smooth.
- Add Broth: Stir in the vegetable or chicken broth. Bring to a gentle simmer for another 10 minutes.
- Canning Process: Follow your preferred canning method (water bath canning is recommended for tomato soup). Ensure you're using properly sterilized jars and lids. Fill the jars, leaving ½ inch headspace. Remove air bubbles, wipe the rims, and seal with lids and rings. Process according to the recommended time for your altitude using a water bath canner. (Consult a reliable canning guide for precise processing times based on your altitude).
How Long Does Canned Tomato Soup Last?
Properly canned tomato soup, stored in a cool, dark, and dry place, can last for 12-18 months. Always check the jars for any signs of spoilage (bulging lids, leakage, or unusual smell) before consuming. Discard any jars showing signs of spoilage.
Can I Freeze Homemade Tomato Soup Instead of Canning It?
Yes, you can freeze homemade tomato soup. Allow the soup to cool completely before freezing in airtight containers. Frozen tomato soup will last for 3-6 months.
What Are the Benefits of Canning My Own Tomato Soup?
Canning your own tomato soup offers several advantages:
- Control over Ingredients: You can choose high-quality ingredients and avoid unwanted additives or preservatives.
- Cost Savings: Making your own soup can be significantly cheaper than buying store-bought versions, especially when you grow your own tomatoes.
- Fresh Flavor: Homemade tomato soup retains the vibrant taste of fresh tomatoes.

What Safety Precautions Should I Take When Canning Tomato Soup?

- Follow Canning Instructions Carefully: Pay close attention to processing times and procedures.
