Roasted Tomato and Red Pepper Soup

Smooth red tomato soup topped with basil in a patterned bowl beside toasted bread

A late-summer harvest can become a winter lunch: roast ripe tomatoes and red peppers for a sweet, full-flavoured soup.

Serves 4 | Preparation: 15 minutes | Cooking: 45 minutes | Total: 60 minutes

Ingredients

  • 800 g ripe tomatoes, halved

  • 2 red peppers (350 g), deseeded and quartered

  • 1 onion (180 g), cut into wedges

  • 3 garlic cloves, unpeeled

  • 30 ml olive oil

  • 500 ml vegetable stock

  • 15 g basil leaves, or 1 tsp dried oregano

  • 10 ml balsamic vinegar, optional

  • Salt and black pepper

Method

  1. Heat the oven to 220°C (200°C fan). Put tomatoes, peppers, onion and unpeeled garlic on a large tray. Toss with oil and season lightly. Roast for 30–35 minutes, turning the peppers once, until tender and browned at the edges.

  2. Let the garlic cool enough to handle and squeeze it from its skin. Transfer vegetables and all tray juices to a saucepan. Add stock and oregano if using.

  3. Simmer for 10 minutes. Remove from the heat, add fresh basil if using and blend with a stick blender, keeping the blade submerged. Pass through a sieve if you prefer to remove seeds and skins.

  4. Taste and add balsamic vinegar only if it needs a little sharpness. Adjust seasoning and thickness, then heat until piping hot.

Variations and substitutions

Use 2 tins chopped tomatoes (400 g each) instead of fresh: roast only peppers, onion and garlic, then simmer with tinned tomatoes and stock for 20 minutes; allow 10 minutes more cooking overall. Add ½ tsp chilli flakes for heat, or 60 ml cream for richness.

Homegrown and seasonal produce

Use fully ripe, sound tomatoes and red peppers from the garden. This is a good way to freeze a ripe harvest for autumn and winter; roast first for the best flavour. Do not substitute green tomatoes in this recipe: use the separate green tomato soup recipe.

Storage and freezing

Cool quickly in shallow containers, refrigerate within 2 hours at 5°C or below and eat within 48 hours. Freeze for up to 3 months. Defrost in the fridge, use within 24 hours and reheat once until piping hot throughout. Add fresh basil garnish after reheating.
