Ingredients

Scale

Gather these ingredients to make your Leeks Vinaigrette (Vinaigrette aux Poireaux):

  • 4 large leeks
  • Water
  • Salt

For the Vinaigrette:

  • 3 tablespoons olive oil (extra virgin preferred)
  • 1 tablespoon red wine vinegar (or white wine vinegar, lemon juice)
  • 1 teaspoon Dijon mustard
  • 1 tablespoon chopped fresh herbs (parsley, chives, tarragon, or a combination)
  • Salt and freshly ground black pepper, to taste

Optional additions:

  • 2 hard-boiled eggs, chopped
  • 1 tablespoon capers, drained
  • 1 tablespoon cornichons, chopped

Instructions

Prepare the Leeks:

  1. Trim the Leeks: Trim off the dark green tops of the leeks, leaving about 2 inches of the light green part. Also, trim off the root end, leaving a small amount intact to hold the layers together.

  2. Clean the Leeks: Leeks tend to trap dirt between their layers. To clean them thoroughly, slice each leek lengthwise down to just above the root end. Fan out the layers and rinse well under cold running water, making sure to remove all traces of dirt and sand.

  3. Cut into Sections: Cut the cleaned leeks into sections about 3-4 inches long.

Cook the Leeks:

  1. Cook in Boiling Water: Bring a pot of salted water to a boil. Gently add the leek sections to the boiling water.

  2. Simmer Until Tender: Reduce the heat to a simmer and cook the leeks for about 15-20 minutes, or until they are tender when pierced with a fork.

  3. Drain and Cool: Carefully remove the leeks from the pot with a slotted spoon and transfer them to a colander to drain. Allow them to cool to room temperature or chill them in the refrigerator for a few hours.

Prepare the Vinaigrette:

  1. Combine Ingredients: In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, chopped fresh herbs, salt, and freshly ground black pepper until well combined.

  2. Taste and Adjust: Taste the vinaigrette and adjust the seasoning as needed, adding more salt, pepper, vinegar, or herbs to your liking.

Assemble the Dish:

  1. Arrange Leeks: Arrange the cooked and cooled leek sections on a serving platter or individual plates.

  2. Dress with Vinaigrette: Drizzle the vinaigrette generously over the leeks, making sure to coat them evenly.

  3. Add Optional Additions: If using, sprinkle the chopped hard-boiled eggs, capers, and/or cornichons over the leeks.

Serve:

  1. Chill (Optional): Leeks Vinaigrette can be served immediately or chilled in the refrigerator for a short time to allow the flavors to meld.

  2. Garnish: Garnish with extra fresh herbs, if desired. Serve as an appetizer, light lunch, or side dish.
