This is a blended tomato soup made with heirloom tomatoes, fresh basil, and a splash of heavy cream — straightforward enough for a weeknight but good enough to serve to guests. The whole thing comes together in one pot in about an hour, and the result is smooth, rich, and genuinely satisfying. If you have ripe tomatoes and a blender, you’re most of the way there.
Ingredient notes
- Heirloom tomatoes: These are worth seeking out when they’re in season because they’re sweeter and less watery than standard supermarket tomatoes. Out of season, good-quality canned whole tomatoes (about 800g drained) work better than pale fresh ones.
- Heavy cream: Use full-fat for the smoothest result. For a dairy-free version, full-fat coconut cream works — just know it adds a faint coconut flavor that most people don’t mind but some notice.
- Broth: The recipe calls for chicken or vegetable broth. Either works, but a low-sodium version gives you more control over the final seasoning since you’re reducing the soup for 20 minutes.
- Fresh basil: Don’t substitute dried here — the basil goes in at the end and dried won’t give you the same result. If your bunch is large, use the leaves generously; they mellow once the soup is warm.
What makes this version work
Two things matter most. First, letting the onion go properly golden — not just soft, but actually golden — before you add anything else. That extra few minutes of patience builds a savory base that carries the whole soup. Second, adding the cream and basil after blending rather than before. Blending hot cream can make it grainy, and basil loses its brightness fast under prolonged heat. Stir both in once the soup is smooth, then give it just five more minutes on low. That’s it. Skip the garnish — not worth the extra dish.
If something goes sideways
- Soup tastes flat or acidic: A small pinch of sugar (start with a quarter teaspoon) balances out tomatoes that are underripe or too sharp. Add it after blending so you can taste as you go.
- Texture is grainy or separated after adding cream: The heat was probably too high. Take the pot off the burner for a minute before stirring in the cream, then return it to the lowest setting.
- Soup is too thin: Simmer uncovered for an extra 5–10 minutes after blending to reduce it. Don’t add flour or cornstarch — it changes the texture noticeably.
- Blender lid blows off mid-blend: Hot liquid expands. If you’re using a countertop blender, fill it no more than halfway, hold the lid down with a folded dish towel, and start on the lowest speed.
- Basil turned dark and dull: It was added too early or cooked too long. Stir it in right at the end and serve within a few minutes — the color fades quickly once it hits heat.
Leftovers and make-ahead
This soup keeps well in the fridge for up to 4 days in a sealed container. It also freezes cleanly for up to 3 months — freeze it before adding the cream if you want the best texture, then stir in the cream when you reheat. To reheat from the fridge, warm it gently in the same pot over medium-low heat, stirring occasionally; high heat can make the cream separate. If the soup thickens in the fridge, add a splash of broth or water to loosen it back up.
Creamy Tomato Basil Soup
Ingredients
- 2 tablespoons olive oil extra virgin for best flavor
- 1 large onion finely chopped
- 2 cloves garlic minced
- 800 grams heirloom tomatoes ripe and coarsely chopped
- 3 cups chicken or vegetable broth, preferably homemade
- 1 cup heavy cream for a velvety texture
- 1 bunch fresh basil leaves only, torn
- 1 pinch salt to taste
- 1 pinch ground black pepper to taste
Instructions
- Heat the olive oil in a large pot over medium heat. Add the chopped onion and sauté until golden brown for about 5-7 minutes, stirring occasionally to prevent burning.
- Add the minced garlic and cook for another minute or until fragrant.
- Stir in the chopped tomatoes and cook until they start to break down, about 10-15 minutes, stirring occasionally.
- Pour in the chicken or vegetable broth, bring to a boil, then reduce the heat and simmer for 20 minutes. Stir occasionally and allow the flavors to meld.
- Use an immersion blender to purée the soup until smooth. Alternatively, blend in batches in a blender, ensuring the soup cools slightly to avoid splattering.
- Stir in the heavy cream and torn basil leaves. Season with salt and black pepper to taste. Simmer gently for an additional 5 minutes.

FAQ
Can I use regular tomatoes instead of heirloom?
Yes, any ripe tomato will work. Roma or vine tomatoes are the most reliable substitutes because they’re fleshy and not too watery — just make sure they’re actually ripe, or the soup will taste thin and acidic.
Do I need an immersion blender, or will a regular blender work?
A regular countertop blender works fine. Let the soup cool for 5–10 minutes first, blend in batches filling the jar no more than halfway, and hold the lid down firmly with a folded towel — hot liquid creates pressure.
Can I make this soup vegetarian?
Yes — just use vegetable broth instead of chicken broth. Everything else in the recipe is already vegetarian.
My family doesn’t like chunks — will this really be smooth?
If you blend it long enough, yes. Run the blender for a full 60–90 seconds per batch rather than just a quick pulse, and the soup will be completely smooth with no tomato skin pieces.
Can I make this ahead for a dinner party?
Absolutely — it’s actually better the next day once the flavors have had time to settle. Make it through the blending step, refrigerate, then stir in the cream and basil when you reheat it just before serving.
How do I know when the tomatoes have cooked down enough before adding the broth?
They should look visibly broken down and jammy, with most of the liquid cooked off — usually around the 12–15 minute mark. If they still look like chopped tomatoes sitting in juice, give them a few more minutes.
