British tomato soup is a smooth, gently savoury soup made with tomatoes, onion, carrot and stock, often finished with a little cream. This home-style version uses tinned tomatoes for dependable flavour, with a fresh-tomato option when they are ripe and in season; recipes vary, but the method is simple and makes a warming lunch or light supper.
Ingredients
- 2 tablespoons (30 ml) olive oil or neutral cooking oil
- 1 medium yellow or brown onion, about 1 cup chopped (150 g)
- 1 medium carrot, peeled and diced, about 1 cup (100 g)
- 1 celery rib, finely diced, about ½ cup (60 g)
- 2 garlic cloves, finely chopped or crushed (about 6 g)
- 2 tablespoons (30 g) tomato purée, also called tomato paste
- 2 cans chopped or whole peeled tomatoes, 14 oz each (2 × 400 g; 800 g total), including their juices
- 2 cups (480 ml) vegetable stock or chicken stock, preferably low-sodium
- 1 small bay leaf
- 1 teaspoon (4 g) granulated sugar, optional
- ¾ teaspoon fine salt (about 4.5 g), plus more to taste
- ¼ teaspoon freshly ground black pepper (about 0.5 g), plus more to taste
- ⅓ cup (80 ml) double cream or heavy cream, optional
Instructions
- Prepare the vegetables. Peel and chop the onion and carrot into small, even pieces, then finely dice the celery and garlic. Small pieces soften quickly and blend into the soup without leaving noticeable hard bits. Open the tomatoes and measure the stock before you begin cooking so everything is ready to add.
- Soften the vegetables. Warm the oil in a large, heavy-based saucepan over medium heat. Add the onion, carrot and celery and cook for 10 minutes, stirring every minute or two. The vegetables should soften and the onion turn translucent, but they should not take on much colour. If the pan begins to catch, lower the heat and add a tablespoon of water rather than letting the onion burn.
- Cook the garlic and tomato purée. Stir in the garlic and tomato purée and cook for 1 minute, stirring continuously. This short cooking step takes away the raw, tinny edge of the purée and spreads it through the vegetables. Do not let the garlic brown, as browned garlic can make a smooth tomato soup taste bitter.
- Simmer the soup. Add the tomatoes and their juice, stock, bay leaf, sugar if using, salt and pepper. Stir well, scraping the bottom of the pan to loosen any tomato purée. Bring the liquid to a gentle simmer, then lower the heat, cover the pan loosely and cook for 25 minutes. Stir once or twice. The carrot should be completely tender when pierced with a knife; if it is still firm, simmer for a few more minutes before blending.
- Blend until smooth. Remove the bay leaf. Blend with an immersion blender for about 3 minutes, moving the blender around the pan until the soup is evenly smooth. For a countertop blender, work in small batches and do not fill the jug more than halfway with hot soup; vent the lid according to the blender’s instructions and hold a folded tea towel over it. Return the blended soup to the pan.
- Finish and adjust. Stir in the cream, if using, and warm the soup gently for 1 minute without letting it boil. Taste and adjust the salt, pepper or sugar. Tomatoes vary in sweetness and acidity, so add sugar only if the soup tastes sharply acidic, and add it a pinch at a time. If the soup is thicker than you like, loosen it with a splash of stock or hot water; if it is too thin, simmer it uncovered for a few minutes.
Tips
- Choose tomatoes with flavour. Good-quality tinned tomatoes are a reliable choice when fresh tomatoes are out of season. If using fresh ones, choose ripe, fragrant tomatoes rather than pale, firm ones; bland tomatoes make a bland soup.
- Keep the heat gentle. Browning the vegetables is not necessary here. A slow, even softening gives the soup a mild sweetness, while scorched onion or garlic can leave a bitter taste that is difficult to correct.
- Control the texture. Blend thoroughly for a silky soup, or stop earlier if you prefer a little texture. For an especially smooth finish, pass the blended soup through a fine-mesh sieve, though this is optional and will leave a small amount of pulp behind.
- Make it dairy-free. Leave out the cream or use an unsweetened plant-based cream. The soup will be a little less rich without dairy; a small drizzle of olive oil at the end adds roundness without changing the tomato flavour much.
Serving Suggestions
Serve the soup hot in warmed bowls, with black pepper and a small swirl of cream if you like. A little chopped parsley or basil makes a fresh garnish, but it is optional; the soup is intended to taste primarily of tomatoes, not herbs. Offer crusty bread, a warm bread roll or buttered toast for dipping. For a familiar British-style lunch, pair it with a cheese toastie or a simple cheese sandwich. Keep those accompaniments separate until serving so their crisp or toasted texture does not soften in the soup.
For a lighter meal, serve a smaller bowl alongside a green salad dressed with a sharp vinaigrette. If the soup is part of a larger meal, modest portions work well before a savoury pie, baked potato or roast vegetables. A little grated mature cheddar on top is another practical garnish, especially with toast, but use it sparingly so it does not overwhelm the tomatoes.
Variations
- Use fresh tomatoes: Replace the two cans with about 2 lb (900 g) ripe fresh tomatoes, roughly chopped. Add them with the stock and simmer as directed; there is no need to peel them if you will blend the soup. Fresh tomatoes can be less concentrated than tinned ones, so the finished soup may taste lighter and may need a little longer to reduce.
- Add herbs: Simmer the soup with 1 teaspoon (about 1 g) dried thyme or 1 tablespoon (about 4 g) chopped fresh basil. Remove woody thyme stems before blending. Basil gives a sweeter, more aromatic result, while thyme makes the flavour more savoury.
- Make it richer: Stir in up to ½ cup (120 ml) cream instead of ⅓ cup, or finish each bowl with a spoonful of crème fraîche. More dairy softens the tomato’s acidity and makes the soup richer, so taste again before adding extra salt.
- Add gentle warmth: Stir in a pinch of chilli flakes (about ⅛ teaspoon or 0.3 g) with the garlic. This adds a mild heat rather than changing the soup into a spicy dish; leave it out for a more traditional, mellow bowl.
Storage and Reheating
Cool leftover soup promptly and refrigerate it within 2 hours of cooking in a covered, shallow container. It keeps for 3–4 days in the refrigerator. Reheat only the portion you need in a saucepan over medium-low heat, stirring often, until it is steaming throughout and reaches 165°F (74°C), the safe temperature for reheated leftovers. Check the centre with a food thermometer. Avoid a hard boil, particularly if cream has been added, because vigorous boiling can make the texture less smooth.
To freeze, cool the soup and pack it into freezer-safe containers, leaving a little room for expansion. Freeze for up to 3 months for best quality, then thaw overnight in the refrigerator. Cream can separate slightly after freezing, so if you are making soup ahead, freeze it before adding the cream and stir the cream in after reheating. If it has already been frozen with cream, whisk or blend it briefly as it warms. Do not store homemade soup at room temperature or use this recipe as a canning method.
Frequently Asked Questions
Can I make British tomato soup without cream?
Yes. The cream is optional, and the soup is still smooth and flavourful without it. Blend the vegetables thoroughly and taste before serving. If you want a richer finish without dairy, add a small drizzle of olive oil to each bowl or use an unsweetened plant-based cream.
Why does my tomato soup taste sour?
Tomatoes differ in acidity, and some tinned or fresh tomatoes taste sharper than others. First check the seasoning: a little more salt can make the flavour seem rounder. If it is still too sharp, stir in the optional sugar a pinch at a time, or add a little cream. Avoid adding a large amount of sugar at once, which can make the soup taste sweet rather than balanced.
Do I need to peel fresh tomatoes?
No, not if you are blending the soup. The skins soften during simmering and most immersion blenders break them down. If you want a very fine texture, pass the blended soup through a sieve; peeling is another option, but it adds preparation time and is not essential.
Can I make the soup ahead?
Yes. Make it through the blending step, cool it promptly, and refrigerate it for up to 3–4 days. Reheat it to 165°F (74°C) before serving, then stir in the cream and adjust the seasoning. This approach is useful if you want to preserve the smoothest texture and avoid reheating the cream more than necessary.
Can I use a regular blender for hot soup?
Yes, provided the blender’s instructions allow hot liquids. Blend in small batches, fill the jug no more than halfway, and leave a way for steam to escape as directed by the manufacturer. Hot soup expands and can force the lid off; never seal a full blender jug tightly while blending hot liquid.
How can I make the soup thicker or thinner?
For a thicker soup, simmer it uncovered for a few minutes after blending so some liquid evaporates. For a thinner soup, stir in hot stock or water a little at a time until it reaches the consistency you prefer. Make changes before serving, then taste once more because added stock can dilute the seasoning.
