Braised leeks with sauce vierge

Side Serves 4 20 min
Sauce vierge is a French sauce made from olive oil, lemon juice, chopped tomatoes and basil. Served over leeks, it makes a good vegetarian side to grilled or oven-baked fish, or griddled halloumi. You could also eat it stirred through pasta for an even quicker dinner.


  • 4 leeks, sliced lengthways, roots intact
  • veg stock
  • 2 tomatoes
  • 100ml olive oil
  • juice of ½ lemon, more to taste
  • 8 basil leaves, shredded
  • salt and pepper


Prep time: 10 min
Cooking time: 10 min
  • Step 1

    Rinse the leeks in cold water to remove any grit. Top and tail and cut into 7-8cm pieces.
  • Step 2

    Place cut-side down in a frying pan and add enough stock to come halfway up the sides of the leeks. Bring to the boil and simmer for 6-8 minutes, until tender.
  • Step 3

    Drain off any excess liquid. While the leeks are simmering, cut a small cross in the top of the tomatoes. Plunge into a heatproof bowl of boiling water for 45 seconds. Remove and plunge into a bowl of cold water.
  • Step 4

    Remove the skins and cut into wedges. Discard the seeds and finely chop the flesh.
  • Step 5

    Gently warm with the olive oil, adding lemon juice and seasoning to taste. Stir in the basil leaves and drizzle over the leeks to serve.
