The Ingredients That Make This Soup Work
Every ingredient in this recipe has a purpose, contributing to the balance of flavour, texture, and aroma that makes roasted tomato basil soup such a classic. Here’s a quick look at what each element brings to your bowl:
-
Ripe Tomatoes (4 pounds, halved for roasting): The heart of the recipe, ripe tomatoes develop a deep, caramelised sweetness when roasted, forming the base flavour of the soup.
-
Garlic (4 cloves, whole and unpeeled): Roasting garlic in its skin mellows its sharpness, giving a nutty, slightly sweet undertone that enhances the tomato’s richness.
-
Olive Oil (2 tablespoons): Helps in roasting by ensuring the tomatoes and garlic cook evenly, while also adding a subtle fruity note.
-
Salt (1 teaspoon, or to taste): Essential for balancing the natural acidity of tomatoes and bringing out the depth of other ingredients.
-
Black Pepper (½ teaspoon, freshly ground): Adds a gentle warmth and sharpness that cuts through the creaminess of the soup.
-
Fresh Basil Leaves (1 cup, packed): Basil is what lifts this dish—its fresh, peppery sweetness gives the soup its signature herbal aroma.
-
Vegetable or Chicken Broth (1 cup): Provides body and enhances the roasted tomato base, turning the puree into a well-rounded soup.
-
Heavy Cream (¼ cup, optional): Adds richness and a velvety texture, perfect for those who prefer a slightly indulgent version of the soup.
How To Make Roasted Tomato Basil Soup
Let’s walk through the process step by step. Each stage builds flavour and ensures the soup is smooth, balanced, and ready to serve.
Step 1: Roast the Tomatoes and Garlic
Preheat your oven to 400°F (200°C). Arrange the halved tomatoes and unpeeled garlic cloves on a large baking tray. Drizzle them with olive oil, then season lightly with salt and freshly ground black pepper. Roast for about 35–40 minutes, until the tomatoes look caramelised at the edges and the skins begin to blister. This step intensifies their natural sweetness and gives the soup a deeper, roasted flavour.
Step 2: Prepare the Base
Allow the roasted tomatoes and garlic to cool just enough to handle. Gently squeeze the softened garlic out of its skins into a blender, discarding the peels. Add the roasted tomatoes to the blender along with the fresh basil leaves. Blend until the mixture turns into a smooth, bright red puree. If your blender is smaller, do this in batches to maintain an even consistency.
Step 3: Build the Soup
Transfer the tomato-basil puree into a large cooking pot. Stir in the vegetable or chicken broth and bring the mixture to a gentle simmer over medium heat. Allow it to cook for about 10 minutes so the flavours come together and the soup develops a rounded taste.
Step 4: Adjust and Finish
Taste the soup and adjust the seasoning with a little more salt or pepper if required. For those who like a creamy texture, stir in the heavy cream at this stage. Let it warm gently without boiling, so the cream blends smoothly into the soup without curdling.
Step 5: Serve It Right
Ladle the hot soup into bowls, and if you wish, garnish with a drizzle of cream or a few extra basil leaves for freshness. Serve with crusty bread or a simple grilled sandwich for a satisfying meal.

- Preheat your oven to 400°F (200°C). Arrange the halved tomatoes and unpeeled garlic cloves on a large baking sheet, drizzling with olive oil and sprinkling with salt and pepper. Roast until the tomatoes are deeply caramelized and starting to burst, about 35-40 minutes, filling your kitchen with a fragrant aroma.
- Once roasted, let the tomatoes and garlic cool slightly. Squeeze the roasted garlic out of their skins into a blender, discarding the skins. Add the roasted tomatoes to the blender along with the basil leaves.
- Puree the mixture until smooth and vibrant red, reminiscent of sunshine. If needed, blend in batches for a silky, even consistency, ensuring no chunks remain.
- Transfer the blended tomato mixture to a large pot and stir in the vegetable broth. Bring it to a gentle simmer over medium heat, allowing the flavors to meld and the soup to warm through, about 10 minutes.
- Taste the soup and adjust seasoning with more salt or pepper if desired. For a creamier finish, stir in the heavy cream just before serving, allowing it to heat gently without boiling.
- Serve the soup hot, garnished with additional basil leaves or a drizzle of cream if you like. The result is a velvety, smoky tomato soup with a bright herbal note and a smooth, inviting appearance.
