This recipe, inspired by her resourcefulness, captures that same heartwarming essence, proving that you don’t need a ton of salt to create a truly unforgettable bowl of soup.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Servings: 3-4
• Yield: 3-4 cups
• Dietary Type: Vegetarian (easily Vegan)

Ingredients

• 3 tablespoons unsalted butter, melted
• 1 medium onion, chopped
• 1/4 teaspoon pepper
• 1 teaspoon salt or 1 teaspoon Morton Lite Salt (for lower sodium)
• 1 (14 1/2 ounce) can no-salt-added diced tomatoes
• 1 (14 1/2 ounce) can low sodium chicken broth (vegetable broth for vegan)
• 2 tablespoons homemade pesto sauce or 2 tablespoons bottled pesto sauce
• 1/2 cup cream (optional, use coconut cream for vegan)

Equipment Needed

• Large skillet
• Blender (or immersion blender)

Instructions

1. Begin by melting the 3 tablespoons of unsalted butter in a large skillet over medium heat. Ensure the entire pan is coated with the melted butter to prevent sticking.

2. Once the butter begins to bubble slightly, add the chopped 1 medium onion. Sauté the onions until they become tender and translucent, stirring occasionally to prevent browning. This usually takes about 5-7 minutes.

3. Add the 1/4 teaspoon pepper and either 1 teaspoon salt or 1 teaspoon Morton Lite Salt to the skillet. Stir to combine, ensuring the spices are evenly distributed among the onions.

4. Pour in the 1 (14 1/2 ounce) can of no-salt-added diced tomatoes and the 1 (14 1/2 ounce) can of low sodium chicken broth (or vegetable broth). Stir well to combine all the ingredients.

5. Bring the mixture to a simmer, then reduce the heat to low. Cover the skillet and allow the soup to simmer gently for 20 minutes, stirring occasionally. This allows the flavors to meld together beautifully.

6. Carefully transfer the soup to a blender in two batches (do not overfill). Blend each batch until completely smooth. Alternatively, use an immersion blender directly in the skillet until the soup reaches your desired consistency. Be careful of splattering hot soup.

7. Pour the blended soup back into the skillet. Stir in the 2 tablespoons of homemade pesto sauce (or bottled) and the 1/2 cup cream (if using). For a richer flavor, you can add the pesto a few minutes before blending so the flavors simmer, but adding it after blending preserves the vibrant color of the basil.

8. Return the soup to low heat for an additional 5 minutes, stirring constantly, to ensure the pesto and cream are fully incorporated and the soup is heated through. Be careful not to boil.

9. Serve hot and enjoy!

Expert Tips & Tricks

• For a deeper tomato flavor: Roast the diced tomatoes in the oven at 400°F (200°C) for 20 minutes before adding them to the soup. This concentrates their sweetness and adds a subtle smoky note.
• Adjusting the consistency: If you prefer a thinner soup, add more low-sodium broth or water. For a thicker soup, blend in a cooked potato or simmer uncovered for a longer period to reduce the liquid.
• Enhancing the basil flavor: Add a handful of fresh basil leaves to the soup during the last 5 minutes of simmering for a more intense basil aroma. Remove before blending if you prefer a smoother texture.
• Make-ahead tip: Prepare the soup through step 6 and store it in the refrigerator for up to 3 days. Add the pesto and cream just before reheating and serving.
• Dealing with acidity: If the soup is too acidic for your taste, add a pinch of sugar or a small amount of baking soda (start with 1/8 teaspoon) to neutralize the acidity.

Serving & Storage Suggestions

Tomato basil soup is incredibly versatile and pairs well with a variety of accompaniments. Serve it with a grilled cheese panini, crusty bread for dipping, or a simple side salad. A dollop of plain Greek yogurt or a swirl of olive oil can also add a touch of elegance.

To store leftovers, allow the soup to cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to 3-4 days. For longer storage, freeze the soup in freezer-safe containers for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

To reheat, gently warm the soup on the stovetop over medium-low heat, stirring occasionally, until heated through. Avoid boiling, as this can affect the texture and flavor. If the soup has thickened during storage, add a splash of broth or water to thin it out.

FAQs (Frequently Asked Questions)

Q: Can I use fresh tomatoes instead of canned?
A: Absolutely! Use about 2 pounds of fresh tomatoes, peeled and chopped, in place of the canned tomatoes. You may need to simmer the soup for a longer period to allow the flavors to develop fully.

Q: How can I make this soup even lower in sodium?
A: Use homemade low-sodium broth or water instead of store-bought broth. Omit the added salt entirely and rely on the natural flavors of the tomatoes and basil. You can also add a squeeze of lemon juice for brightness.

Q: Can I freeze this soup?
A: Yes, tomato basil soup freezes well. Allow the soup to cool completely before transferring it to freezer-safe containers. Freeze for up to 2-3 months.

Q: What if I don’t have pesto?

Q: How do I prevent the soup from curdling when adding cream?
A: Temper the cream by gradually adding a small amount of the hot soup to the cream before stirring it into the entire pot. This helps to prevent curdling. Also, ensure the soup is not boiling when you add the cream.
