Leeks Vinaigrette


A French classic, whole leeks are boiled, drained, then marinated in a Dijon vinaigrette.

Ah the noble leek, often the bridesmaid, rarely the bride. Leeks vinaigrette is a classic French recipe that honors the leek for itself.

In this recipe we first clean and prep the leeks, then boil them in water until just cooked, drain them, and marinate them for several hours (or days) in a vinaigrette with a touch of Dijon mustard.

Served at room temperature, the leeks make a lovely salad or side. And given that they love a long marinating time, they’re perfect for making ahead. 

This recipe comes from my Frenchman Guy (that’s “Gee” with a hard “g”) who grew up eating “poireaux vinaigrette” in France. He made it for my mother’s 78th birthday last week, which we served as a first course to a lasagna bolognese (so good!).

He also roasted up some red bell peppers and served them with the leeks, which were lovely together.

Funny thing about the leek greens. Recipes almost always say, “use the white and pale green parts only,” but the green tops are full of flavor.

We often use green onion greens in recipes. Using more of the dark green tops of leeks is similar.

They are a little tougher than the white and pale green parts, but if you are boiling them as in this method, they should tenderize fine with the cooking.

Leeks Vinaigrette Recipe

  • Prep time: 10 minutes
  • Cook time: 20 minutes
  • Yield: Serves 4 to 6

Choose leeks that are about an inch thick and have a long, white and pale green shaft.


  • 6 long leeks (about 2 to 2 1/2 pounds total)
  • 1/4 cup extra virgin olive oil
  • 1 tablespoon red wine vinegar
  • 1 teaspoon Dijon mustard
  • 1/4 teaspoon Kosher salt
  • 1/4 teaspoon finely ground black pepper


1 Heat a pot of water, clean the leeks: Bring a large, wide (12 inches) pot, half-full of salted water (2 teaspoons of salt for 2 quarts of water) to a boil. While the water is heating, clean the leeks, keeping them whole.

To do this, first rinse off any visible dirt from the leeks. Then, use the tip of a sharp knife to pierce the leek just a little bit below the point where the leek's shaft opens up into separate leaves.

Cut the leek from this point all the way out to the tip of the green leaves, keeping the shaft whole.

Open up the leaves, and place the leek under running water to clean out any dirt or sand that may be hiding between the leaves.

Cut off the dark green tops, leaving about an inch or two (or three if you like the more strongly flavored greens) on the shaft.

Cut off the roots, cutting as close to the roots as possible, to help keep the leek together while it simmers in the next step. (For a visual step-by-step, see How to Clean Leeks.)

2 Simmer the leeks in salted water: Once the water is boiling, carefully place the cleaned and prepped leeks into the water.

Return to a simmer and lower the heat to maintain a simmer. Start a timer and cook for 8 to 10 minutes, or until the thickest part of the thickest leek can easily be penetrated with the tip of a sharp knife.

If your leeks are about an inch thick, they should just begin to be turning from bright green to olive-y green at the 8 minute mark. Thicker leeks you'll want to cook a little longer.

3 Place cooked leeks in ice water bath: Use tongs to gently remove the leeks from the pot and place into an ice water bath to stop the cooking.

4 Let the leeks drain: Remove the leeks from the ice water bath and let them drain. The best way to let them drain is to place them in a rimmed roasting pan and then propping up the pan at an angle so the water can run out of the leeks.

Let them drain for 10 minutes or so while you make the vinaigrette.

5 Make the vinaigrette: Place the olive oil, vinegar, mustard, salt, and pepper, in a jar and whisk until well emulsified.

6 Marinate the leeks in the vinaigrette: Place the leeks in a rimmed, long serving dish (a Pyrex casserole dish would work for this as well). Drizzle some vinaigrette over the leeks. Gently turn the leeks over and drizzle a bit more vinaigrette on the other side.

leeks marinating in vinaigrette

Cover with plastic wrap and let the leeks marinate in the vinaigrette for at least 2 hours, or up to 3 days. (Chill if marinating more than 2 hours.

The longer they marinate, the tastier and more tender they become.)

The leeks should be served at room  temperature.

Alternative serving suggestion: cut the marinated leeks crosswise into 1-inch long segments and serve with strips of roasted red bell peppers that have been marinating in the same vinaigrette.

    Yum! I wonder if I could grill the leeks and use the vinaigrette as the dressing once they’re cooked?

    Classic’ish recipe, SO good. The “ish” is only comes from the plating….the leeks are traditionally are alternating in directions. I gave my daughter the cookbook /recipe I had for the vinaigrette, very happy I found yours. Just lovely.

    If the usually overlooked and/or discarded dark green tops of leeks are to be used in a soup or stock, do they replace the onions typically used in the base sauté, or are they IN ADDITION TO the onion-garlic-carrot-celery base?

    I’ve always wondered why the top parts get discarded here. In Polish cuisine, the white and light green parts are used in salads and the dark portion is chopped up and used in soups. This looks and tastes absolutely wonderful!
