Why this works

A light, vegetable-based soup with moderate natural sugars and fibre; the added salt makes it relatively high in sodium.

Beta-carotene from carrots and sweet potatoes. Provides provitamin A carotenoids, which support normal vision, skin and immune function.

Fibre for digestive health. Carrots, sweet potatoes and onions contribute useful fibre to support gut health and satiety.

Sodium concern. 1 tsp of salt across 4 servings makes this soup relatively high in sodium, which may not suit those limiting salt.

Method

  1. Preheat the oven to 200°C (Fan 180°C, 392°F, Gas Mark 6). Peel and roughly chop the carrots, sweet potatoes and white onions, then place them on a roasting tray with the garlic cloves.
  2. Season with salt and black pepper, then roast for 30–35 minutes until the vegetables are tender and lightly caramelised.
  3. Tip the roasted carrots, sweet potatoes, onions and garlic into a large saucepan, then add enough hot water to just cover the vegetables.
  4. Bring to a simmer and cook for 10 minutes so the flavours meld together, then blend until smooth and velvety.
  5. Stir through most of the Greek yoghurt, then taste and adjust the seasoning with more salt and black pepper if needed.
  6. Ladle into bowls and finish with a spoonful of the remaining Greek yoghurt on top.
