Homemade Tomato Basil Soup Canning Recipe

Ingredients Needed

Before you dive into the cooking process, let’s gather the essentials. Here’s what you’ll need to make homemade tomato basil soup ready for canning:

• Tomatoes – Ideally, you want ripe, fresh Roma or plum tomatoes. These varieties have a thick flesh, making them perfect for soup. You’ll need about 10-12 medium-sized tomatoes to make a batch.
• Fresh Basil – The star herb! Fresh basil adds a bright, aromatic flavor to your soup. Use at least one bunch (roughly 1 cup when chopped).
• Onions – One medium yellow onion, finely chopped, adds a sweet depth to the soup.
• Garlic – Two to three cloves, minced, for that subtle hint of warmth and savory richness.
• Olive Oil – 2 tablespoons, to sauté your onions and garlic and to help meld the flavors together.
• Vegetable Broth – About 4 cups of low-sodium vegetable broth to provide a smooth, balanced base. You can also use chicken broth if you prefer.
• Sugar – A teaspoon or so helps to balance the acidity of the tomatoes and bring out their natural sweetness.
• Salt – Start with 1-2 teaspoons, depending on your taste preferences.
• Black Pepper – Freshly cracked black pepper to season.
• Lemon Juice – 1 tablespoon of freshly squeezed lemon juice to brighten up the soup and maintain acidity for proper canning preservation.
• Canning Jars and Lids – For preserving your soup safely. Wide-mouth quart jars work well for soup.

Cooking Instructions

Now, let’s get cooking! The process of making homemade tomato basil soup for canning is fairly straightforward, and once you have all your ingredients prepped, you’ll be blending, simmering, and canning like a pro. Here’s a step-by-step guide:

1. Prepare The Tomatoes

   • Start by blanching the tomatoes. Bring a large pot of water to a boil and make shallow X slits at the bottom of each tomato.
   • Drop the tomatoes into the boiling water for about 30 seconds, or until the skins start to peel off.
   • Remove the tomatoes and transfer them into a bowl of ice water to stop the cooking process.
   • Peel off the skins, remove the seeds if you prefer a smoother soup (this is optional), and chop them roughly. Set aside.

2. Sauté Aromatics

   • In a large stockpot, heat 2 tablespoons of olive oil over medium heat.
   • Add the chopped onions and sauté for 5-7 minutes, until they are soft and translucent.
   • Add the minced garlic and cook for another 1-2 minutes, until fragrant.

3. Add Tomatoes And Broth

   • Stir in the prepared tomatoes, vegetable broth, sugar, salt, and pepper.
   • Bring the mixture to a simmer, and let it cook for about 30-45 minutes to allow the flavors to meld together. Stir occasionally.

4. Blend The Soup

   • Once the soup has simmered, it’s time to blend. You can use an immersion blender directly in the pot or transfer the mixture in batches to a regular blender.
   • Blend until smooth and creamy. For a thicker texture, you can leave some chunks of tomatoes if you prefer.

5. Add Basil And Lemon Juice

   • After blending, return the soup to heat and stir in the fresh basil. Let it simmer for another 5-10 minutes until the basil infuses the soup.
   • Stir in the lemon juice to brighten the flavor and maintain the necessary acidity for canning.

6. Prepare For Canning

   • While the soup is still hot, ladle it into sterilized canning jars, leaving about 1-inch of headspace at the top. Make sure the rims of the jars are clean to ensure a proper seal.
   • Wipe down the jar rims with a clean, damp cloth, place the lids on, and tighten the rings.

7. Process The Jars

   • Process the jars in a water bath canner. Place them in the canner and ensure the water covers the jars by at least 1-2 inches.
   • Bring the water to a boil and process for 35-40 minutes. Make sure the jars are fully sealed once they cool (you should hear a “pop” sound as they seal).

Ingredient Insights

Each ingredient in this tomato basil soup plays an essential role in its flavor profile:

• Tomatoes: The heart of the recipe, providing that juicy base. Tomatoes are high in vitamin C and lycopene, a powerful antioxidant that helps support heart health and may reduce the risk of cancer.
• Basil: Fresh basil provides that herbal kick, which balances the richness of the tomatoes. Basil is known for its anti-inflammatory properties, antioxidants, and potential to support digestive health.
• Onions and Garlic: Both ingredients offer a sweet and savory base. Onions are rich in sulfur compounds that may help with detoxification, while garlic is known for its immune-boosting qualities.
• Lemon Juice: Besides adding a bright pop of flavor, lemon juice helps with the acidity balance, ensuring the soup is safe for canning.

Expert Tips

• Skinning Tomatoes: While you can leave the skins on for a chunkier texture, removing them helps create a smoother, more refined soup.
• Balance Acidity: To ensure safe canning, maintain the proper acidity level. If your tomatoes are particularly sweet, you may need to add a little extra lemon juice or a splash of vinegar.
• Test for Seal: After canning, test each jar’s seal by pressing the center of the lid. If it doesn’t pop back, the jar has sealed correctly. Any jars that haven’t sealed should be refrigerated and used soon.
• Blending Tip: For a velvety smooth texture, run the soup through a fine mesh sieve after blending to remove any seeds or skin remnants.

Recipe Variations

The beauty of this soup lies in its versatility. Here are a few ways to mix it up:

• Spicy Tomato Basil Soup: Add a pinch of crushed red pepper flakes or finely chopped jalapeños to bring a bit of heat to the soup.
• Creamy Version: Add a cup of heavy cream or coconut milk after blending the soup for a creamier, more indulgent texture.
• Roasted Tomato Soup: For an extra depth of flavor, roast the tomatoes in the oven before canning them. Roasting caramelizes the sugars in the tomatoes, making them even sweeter and richer.
• Herb Variations: Try adding other fresh herbs like thyme, rosemary, or oregano along with basil for a more complex flavor.

Final Words

Homemade tomato basil soup is not only comforting and versatile but also incredibly easy to can. With just a few simple ingredients and some patience, you can preserve that fresh, garden-picked flavor and enjoy it whenever you want. Whether you’re serving it as a lunch, pairing it with a grilled cheese sandwich, or gifting jars to friends, there’s nothing like the satisfaction of enjoying a homemade jar of soup from your pantry.
