Why You Will Love This Tomato And Red Pepper Soup:
- Deep, Smoky Flavor: Unlike quick stovetop soups, this one gets its complexity from roasting the vegetables first. This caramelizes the sugars, giving the soup a deep, smoky sweetness that removes all the harsh acidity.
- Naturally Rich Texture: The tender, roasted vegetables blend easily with the stock, creating a naturally thick, velvety texture without needing any heavy cream or flour.
- Easy to Make Ahead: This soup freezes perfectly! You can make a large batch when fresh produce is in season, and then pull out a rich, homemade soup on a busy weeknight.
- A Vibrant Centerpiece: The deep red color from the roasted tomatoes and peppers makes this soup look incredibly appetizing and vibrant, elevating a simple bowl of soup into something special.
James Martin Tomato And Red Pepper Soup Ingredients
For Roasting:
- 1 kg (2.2 lbs) ripe plum tomatoes, halved
- 2 large red bell peppers, cored and quartered
- 1 medium red onion, quartered
- 4 cloves garlic, smashed (no need to peel)
- 3 tablespoons olive oil
- 1 teaspoon granulated sugar
- Sea salt and freshly ground black pepper
For the Soup:
- 4 cups (1 liter) vegetable stock
- 1/2 cup fresh basil leaves, torn (plus more for garnish)
- 1 tablespoon balsamic vinegar (optional, for tang)
- Fresh cream or crème fraîche, for drizzling (optional)

How To Make James Martin Tomato And Red Pepper Soup
- Roast the vegetables: Preheat your oven to 400°F (200°C). Place the tomatoes (cut-side up), red peppers, red onion quarters, and smashed garlic on a large, parchment-lined baking tray.
- Season and cook: Drizzle everything generously with olive oil and sprinkle with salt, pepper, and the sugar. Roast for 30 to 40 minutes, or until the peppers are slightly charred and the tomatoes are soft and caramelized.
- Cool and peel: Remove the tray from the oven and let the vegetables cool slightly. Tip: For a smoother soup, the charred skin of the peppers can be gently peeled and discarded now, along with the garlic skins.
- Blend the soup: Transfer the roasted tomatoes, peppers, onion, and soft garlic cloves to a large pot. Pour in the vegetable stock and the torn fresh basil leaves.
- Puree until smooth: Use an immersion blender (or standard blender) to blend the soup until it is completely smooth and velvety.
- Simmer and finish: Return the pot to the stove over low heat. Stir in the optional balsamic vinegar. Taste and season again with salt and pepper. Serve hot with a drizzle of cream.
Recipe Tips
- Roasting is Essential: Do not skip the roasting step. This process caramelizes the natural sugars in the vegetables, which removes their raw acidity and gives the soup a deep, smoky, complex flavor.
- Peel the Peppers: If the skin of the red peppers is very charred, it is best to remove it after roasting. Charred skin can sometimes give a slightly bitter taste to the finished soup.
- Use Sugar Sparingly: The small amount of sugar added before roasting helps balance the acidity of the tomatoes and enhances the caramelization of the red peppers.
- Add a Touch of Vinegar: Stirring in a small amount of balsamic vinegar at the end is a chef’s trick. It adds a necessary tang that lifts the otherwise heavy, savory flavors.

FAQs
Yes to make it creamy, stir in 1/4 cup of heavy cream, crème fraîche, or even a spoonful of mascarpone cheese right before serving. Heat gently and do not let it boil.
his is usually caused by overcooked or scorched garlic, or if the skin of the red peppers was not removed before blending. Next time, roast the garlic separately in foil or discard the charred pepper skins.
While fresh roasting gives the best flavor, you can use two jars (12 oz total) of jarred roasted red peppers, drained. Reduce the roasting time for the fresh tomatoes by 10 minutes.
