Ingredients List

Tomato Basil Soup starts with humble ingredients that, when given a little time and care, transform into something truly special. Here’s what you’ll need.

• 2 tablespoons olive oil or unsalted butter
• 1 large yellow onion, thinly sliced
• 4 cloves garlic, minced
• 1 (28-ounce) can whole peeled San Marzano tomatoes (with their juices)
• 2 cups vegetable broth (chicken broth works too)
• 1/4 cup fresh basil leaves, packed, plus more for garnish
• 1 teaspoon granulated sugar (optional, to balance acidity)
• 1/2 cup heavy cream or half-and-half
• Salt and freshly ground black pepper to taste

Smart Swaps & Notes:

• Canned Tomatoes: San Marzanos are prized for their sweet, low-acid flavor, but any good-quality canned whole tomatoes will work beautifully. You can also use 2 pounds of fresh, ripe Roma tomatoes, roasted first for deeper flavor.
• Cream: For a dairy-free version, full-fat coconut milk adds wonderful richness. For a lighter touch, simply omit the cream—the soup is still deliciously velvety.
• Broth: Use homemade if you have it! It makes a difference. A good low-sodium store-bought broth is a perfect time-saver.
• Herbs: While fresh basil is non-negotiable for that signature flavor, a teaspoon of dried oregano added with the garlic can add a lovely Tuscan-inspired note.

Timing

This Tomato Basil Soup is a testament to how a little patience in the pot yields big flavor, without keeping you in the kitchen all day.

• Prep Time: 10 minutes
• Cook Time: 35 minutes
• Total Time: 45 minutes

That’s about 20% faster than many from-scratch soup recipes that require lengthy roasting, yet it delivers a depth of flavor that tastes like it simmered for hours. It’s the perfect project for a lazy afternoon or a manageable weeknight endeavor.

Step-by-Step Instructions

Let’s walk through making this comforting Tomato Basil Soup together. The process is straightforward, but each step builds the flavor foundation.

1. Build the Flavor Base

In a large pot or Dutch oven, heat the olive oil or butter over medium heat. Add the thinly sliced onions and a pinch of salt. Cook, stirring occasionally, for about 15-20 minutes until the onions are soft, golden, and fragrant. This slow caramelization is the secret—it adds a natural sweetness that balances the tomatoes perfectly. In the last 2 minutes, add the minced garlic and stir until fragrant.

2. Simmer the Soup

Add the entire can of tomatoes (juices and all) and the vegetable broth to the pot. Use a wooden spoon to gently break up the whole tomatoes. Bring the mixture to a gentle boil, then reduce the heat to low, cover, and let it simmer for 15 minutes. This allows all the flavors to meld and deepen.

3. Blend Until Smooth

Remove the pot from the heat. Carefully use an immersion blender directly in the pot to puree the soup until completely smooth. If you’re using a countertop blender, let the soup cool slightly, then blend in batches, holding the lid down with a towel. Safety first: Hot soup expands, so never fill your blender more than halfway.

4. Finish with Cream and Basil

Return the smooth soup to the pot over low heat. Stir in the fresh basil leaves—they’ll wilt instantly and perfume the entire pot. Now, stir in the heavy cream. Taste your Tomato Basil Soup. This is the moment. Season with salt, pepper, and the optional sugar if the tomatoes taste a bit sharp. The sugar isn’t to make it sweet, but to round out the acidity and let the other flavors shine.

5. Serve Warm

Ladle the hot soup into bowls. Garnish with a drizzle of cream, a few fresh basil leaves, and a crack of black pepper. It’s ready to bring comfort to your table.

Equipment Needed

You don’t need any fancy gadgets to make this Tomato Basil Soup. A regular kitchen will have everything required.

• A Large Pot or Dutch Oven: This is your main workhorse. A heavy-bottomed pot ensures even heat distribution, preventing the onions from burning as they caramelize.
• Immersion Blender or Countertop Blender: Essential for that signature velvety texture. An immersion blender is my favorite for easy cleanup.
• Wooden Spoon or Spatula: For stirring and breaking up the tomatoes.
• Ladle: For serving up those perfect bowls of comfort.

Why You’ll Love This Recipe

This Tomato Basil Soup has earned its permanent spot in my recipe box for so many reasons.

• Bright, Balanced Flavor: Unlike dull, one-note versions, this soup sings with the sweet depth of caramelized onions and the vibrant punch of fresh basil.
• Weeknight-Friendly Elegance: It feels special enough for guests but is simple enough for a tired Tuesday. Regular kitchen, regular time, great results.
• Meal-Prep Champion: It tastes even better the next day and freezes beautifully, making future-you very grateful.
• Endlessly Adaptable: It’s a perfect canvas for your own touches—add a Parmesan rind while simmering, a pinch of red pepper flakes for heat, or a swirl of pesto on top.
• The Ultimate Comfort Pairing: It was practically made for dunking a buttery grilled cheese sandwich. A match made in cozy dinner heaven.

Healthier Alternatives for the Recipe

This Tomato Basil Soup is wonderfully adaptable to various dietary needs without sacrificing an ounce of flavor.

• Dairy-Free/Vegan: Substitute the heavy cream with full-fat canned coconut milk. Its rich texture and mild flavor blend in perfectly. You can also use a cup of raw cashews, soaked and blended until smooth, for a creamy, protein-rich addition.
• Lower Fat: Simply omit the cream altogether. The soup will be a bit lighter but still rich and flavorful from the caramelized onions and blended tomatoes.
• Added Protein: For a heartier, protein-packed meal, stir in a can of rinsed white beans or lentils after blending. It turns this soup into a more substantial main, similar to my Hearty Lentil Vegetable Soup.
• Gluten-Free: This recipe is naturally gluten-free. Just be sure your broth is certified gluten-free if needed.

Serving Suggestions

A bowl of this Tomato Basil Soup is a complete meal in itself, but with the right accompaniments, it becomes a feast.

• The Classic: A golden, crispy grilled cheese sandwich is the non-negotiable partner. Sourdough, cheddar, and a little butter—perfection.
• For Dipping: Serve with a side of garlic bread, cheesy breadsticks, or even simple saltine crackers for that nostalgic touch.
• Salad Side: A simple, crisp green salad with a sharp vinaigrette cuts through the soup’s richness beautifully.
• Garnish Bar: Set out small bowls of toppings: extra fresh basil, a drizzle of good olive oil, homemade croutons, grated Parmesan, or a dollop of ricotta.
• Make it a Soup Flight: For a fun dinner party, serve small cups of this alongside other favorites like my Creamy Broccoli Cheddar Soup or the elegant Butternut Squash Soup. It’s a wonderful way to explore different flavors.

Common Mistakes to Avoid

A few small tweaks can make the difference between a good Tomato Basil Soup and a great one.

• Rushing the Onions: Don’t crank the heat to hurry the caramelization. Medium-low heat and patience are key. Burnt onions taste bitter, while soft, golden onions add a foundational sweetness.
• Using Dried Basil as a Substitute: For the fresh basil flavor that defines this soup, dried basil simply won’t work. If you’re in a pinch, finish the soup with a tablespoon of high-quality prepared pesto instead.
• Adding Cream While Boiling: Always remove the soup from the heat or reduce it to very low before stirring in the cream. High heat can cause the dairy to separate or curdle.
• Underseasoning: Tomatoes and broth need help. Taste diligently at the end and season with salt and pepper in stages. Remember, the optional sugar is a seasoning tool to balance, not sweeten.
• Skipping the Blend: For the silky texture that makes this soup so luxurious, you must blend it completely. A few quick pulses with an immersion blender won’t do it—blend until you can’t see any tomato or onion pieces.

Storing Tips for the Recipe

This Tomato Basil Soup is a gift that keeps on giving, making it ideal for planning ahead.

• Refrigerating: Let the soup cool completely, then transfer it to an airtight container. It will keep beautifully in the fridge for 4-5 days. The flavors meld and deepen overnight.
• Freezing: This soup freezes exceptionally well. Omit the cream before freezing (dairy can separate). Freeze the pureed, cream-free soup in freezer-safe bags or containers for up to 3 months. Thaw overnight in the fridge, reheat gently, and stir in the cream when warming.
• Reheating: Warm the soup gently over medium-low heat on the stovetop, stirring occasionally. If it seems too thick after storage, thin it with a splash of broth or water. Avoid boiling to protect the texture and fresh basil flavor.
