- 9.3g (5.7g saturated)
- 11.1g (5g sugars)
- 700ml vegetable stock
- 300ml whole milk

You’ll also need…
- Stick blender
- Put the stock, milk, bay leaves and thyme in a saucepan over a high heat, then bring just to the boil. Reduce the heat to low to keep warm.
- Meanwhile, melt the butter over a low heat in a large saucepan. Add the leeks, potato and a pinch of salt, stir to coat, then turn up the heat to high and cook for 10-12 minutes until tender, stirring frequently to ensure the vegetables don’t colour.
- Pour the stock and milk mixture over the vegetables. Simmer for
15 minutes, then take off the heat and discard the herbs. Using a stick blender, blend until smooth. Pass through a sieve into a deep saucepan (with enough room to submerge the blender blades for frothing later). The soup should have a velvety texture (add a little stock or water if you need to). Taste, season and keep in the saucepan until ready to serve (see Make Ahead).
- To serve, gently warm the soup, then fill each cup three-quarters full. Whizz the remaining soup with the stick blender until frothy, then spoon into the cups.
To keep the vibrant green of the soup, finely and evenly slice the vegetables, then cook on a high heat until tender. Once blended, cool briefly in the fridge or freezer. The key is to limit the time the green part of the leeks, which contains the bright green chlorophyll, is hot.
This dish has little to no waste – even the green leek tops are used. If you have a little bit leftover, stir it into a risotto or pasta bake for a creamy finish.
Make up to 3 days ahead, then cover and chill. Reheat gently over a low heat, then froth the top of the soup with a stick blender just before serving.
A stick blender incorporates lots of air bubbles, giving a light, foamy aerated texture to the top of the soup.
