Roasted tomato and lentil soup

Roasting fresh tomatoes adds depth to a red-lentil soup. Lentils thicken it without cream, and a potato masher gives texture without handling a blender full of hot liquid.

Ingredients

  • 800g fresh tomatoes, halved
  • 200g dry red lentils, rinsed
  • 1 onion, diced
  • 2 garlic cloves, chopped
  • 2 tbsp olive oil, divided
  • 1 litre vegetable stock
  • 1 tsp dried oregano
  • Black pepper, to taste

Method

  1. Prepare tomatoes and lentils

    Wash tomatoes and remove hard stalk cores before halving. Rinse the red lentils in a sieve and check for debris. Set out a roasting dish and a saucepan large enough for the soup.

  2. Roast the tomatoes

    Heat the oven to 220°C, or 200°C fan. Put tomatoes cut-side up in a roasting dish, drizzle with 1 tbsp oil and scatter with oregano. Roast for 25–30 minutes until softened and beginning to colour.

  3. Simmer the lentils

    Meanwhile heat the remaining oil in a large saucepan. Soften onion for 7 minutes over medium heat, add garlic for 1 minute, then lentils and stock. Bring to a boil and simmer for 20–25 minutes, stirring, until the lentils are soft and breaking down.

  4. Combine and crush

    Carefully scrape the tomatoes and their juices into the soup. Simmer together for 5 minutes. Take off the heat and crush with a potato masher, keeping it below the liquid to avoid splashing. Add hot water if too thick.

  5. Finish

    Add pepper, check everything is hot and ladle into four bowls. Tomato skins remain in this rustic soup.

Make it work with what you have

  • Use red split lentils, not green or brown lentils, for this cooking time and soft texture.
  • This roasting method needs fresh tomatoes; for tinned tomatoes choose the white bean stew instead.
