Ingredients
The foundation of a great soup starts with quality tomatoes and a fragrant base. Fresh tomatoes provide natural sweetness, while canned San Marzano tomatoes add depth and consistency. Aromatics like garlic and onion build the savory backbone, and the cream rounds everything out with a luxurious mouthfeel. Fresh basil lifts the finished bowl with a burst of herbaceous brightness, and a splash of stock ties everything together.
Main Ingredients
- 2 lbs ripe tomatoes, roughly chopped
- 1 (28‑oz) can San Marzano tomatoes, crushed
- 1 cup low‑sodium vegetable broth
Cream & Herbs
- 1 cup half‑and‑half (or whole milk for lighter version)
- 1/2 cup fresh basil leaves, loosely packed
Seasonings & Aromatics
- 1 medium onion, finely diced
- 3 cloves garlic, minced
- 2 tbsp olive oil
- 1 tsp granulated sugar (optional, to balance acidity)
- ½ tsp sea salt, plus more to taste
- ¼ tsp freshly ground black pepper
- Pinch of red‑pepper flakes (optional for heat)
Together these ingredients create a soup that’s both bright and comforting. The fresh tomatoes give a natural sweetness, while the canned tomatoes add depth and a velvety texture. The broth provides a savory backbone, and the half‑and‑half introduces a luxurious creaminess without overwhelming the palate. Fresh basil adds a fragrant, slightly peppery finish, and the careful seasoning ensures each spoonful is perfectly balanced.
Step-by-Step Instructions

Building the Soup Base
Heat the olive oil in a large, heavy‑bottomed pot over medium heat. Add the diced onion and sauté for 4–5 minutes, stirring occasionally, until the onion turns translucent and begins to caramelize. This step develops a sweet foundation that counteracts the tomatoes’ acidity. Then stir in the minced garlic and red‑pepper flakes, cooking just 30 seconds until fragrant—be careful not to let the garlic brown, which would add bitterness.
Simmering & Blending
- Deglaze with broth. Pour the vegetable broth into the pot, scraping the browned bits from the bottom with a wooden spoon. Those caramelized bits are flavor gold, and deglazing lifts them into the liquid for a richer soup.
- Add tomatoes. Stir in the fresh chopped tomatoes and the crushed San Marzano tomatoes. Bring the mixture to a gentle boil, then reduce to a simmer. Let it cook uncovered for 15–20 minutes, stirring occasionally, until the fresh tomatoes break down and the sauce thickens slightly.
- Season and sweeten. Sprinkle in the sugar, sea salt, and black pepper. The sugar isn’t mandatory, but it smooths out any lingering acidity. Taste and adjust seasoning now, keeping in mind the soup will mellow a bit after blending.
- Blend to silk. Remove the pot from heat. Using an immersion blender, puree the soup directly in the pot until completely smooth. If you prefer a completely velvety texture, blend in batches in a countertop blender, returning the puree to the pot.
- Incorporate cream and basil. Return the pot to low heat. Stir in the half‑and‑half, then fold in the fresh basil leaves. Allow the soup to warm through for 3–4 minutes—do not let it boil, as the dairy could separate.
Finishing Touch & Serve
Give the soup a final taste and adjust salt or pepper if needed. Ladle into bowls, drizzle a tiny swirl of extra half‑and‑half or a drizzle of good olive oil, and garnish with a few whole basil leaves for visual appeal. Serve hot with crusty bread or a simple side salad for a complete meal.
Tips & Tricks
Perfecting the Recipe
Use peak‑season tomatoes. When tomatoes are at their ripest, they contribute natural sweetness and reduce the need for added sugar.
Simmer, don’t rush. A gentle simmer allows the flavors to meld and the tomatoes to break down, creating a smoother texture without over‑cooking the basil.
Flavor Enhancements
A splash of good‑quality balsamic vinegar added at the end brightens the soup and balances richness. For a smoky note, stir in a teaspoon of smoked paprika just before blending. Finish with a pinch of freshly grated Parmesan for umami depth.
Common Mistakes to Avoid
Avoid boiling the soup after the cream is added; high heat can cause the dairy to curdle, leaving a grainy texture. Also, don’t skip the blending step—leaving chunks will give a rustic feel but not the silky mouthfeel this recipe aims for.
Pro Tips
Prep ingredients in advance. Dice onions, mince garlic, and measure broth before you start cooking; this keeps the process smooth and prevents over‑cooking.
Keep a splash of broth handy. If the soup becomes too thick during simmering, add a little extra broth to reach your desired consistency.
Fresh basil at the end. Adding basil off the heat preserves its bright flavor and vivid green color, preventing it from turning bitter.
Season in layers. Taste after each major step (sauté, simmer, blend) to build depth without over‑salting.
Variations
Ingredient Swaps
Swap fresh tomatoes for a 2‑cup can of fire‑roasted diced tomatoes for a smoky twist. Replace half‑and‑half with coconut milk for a dairy‑free, slightly tropical version. For a richer mouthfeel, stir in a tablespoon of cream cheese just before serving.
Dietary Adjustments
Make the soup vegan by using plant‑based milk (such as oat or almond) and vegetable broth. For a low‑sodium version, choose a no‑salt broth and reduce added salt, relying on the natural flavors of fresh herbs. Keto dieters can omit the sugar and serve the soup over cauliflower rice.
Serving Suggestions
Serve the soup with a grilled cheese sandwich, a drizzle of pesto, or a side of garlic‑roasted croutons for added texture. Pair it with a crisp arugula salad dressed in lemon vinaigrette for a refreshing contrast, or enjoy it as a starter before a main pasta dish.
Storage Info
Leftover Storage
Allow the soup to cool to room temperature, then transfer it to airtight containers. Refrigerate for up to 4 days. For longer keeping, portion into freezer‑safe bags or containers, label, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating Instructions
Reheat gently on the stovetop over low heat, stirring frequently, and add a splash of broth or milk if the soup has thickened. Alternatively, microwave individual portions covered, heating in 30‑second intervals while stirring, until steaming hot. Avoid boiling to keep the cream smooth.
