  • Frying pan / skillet
  • Large saucepan
  • Small saucepan
  • Whisk


  • 500 g leeks
  • 150 g lardons smoked
  • 250 ml milk
  • 25 g flour
  • 25 g flour
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon nutmeg ground


  • Wash the leeks and remove the outer leaves if necessary. Trim both ends and cut the leeks into portions. For 2 large leeks I cut them in half.
  • Place the leeks in a pan of boiling water and simmer for 5 to 10 minutes until tender.
  • Turn off the heat and leave them in the water to keep warm.
  • Put the milk, butter, flour and seasoning in a small saucepan.
  • Use the whisk to mix in the flour then turn on to a medium heat.
  • Keep whisking continually as the butter melts and the mixture thickens.
  • Turn the heat down and let it cook for a minute to cook the flour. Check the seasoning and add the grated nutmeg.
  • Drain the leeks thoroughly and place them in a serving dish covered with foil.
  • Gently reheat the sauce and pour over the leeks.
  • Scatter the cooked bacon over the top and serve.
