Ingredient Spotlight: Leeks

Milder and softer than their onion cousins, leeks have a delicate flavor that’s perfect for the transition into spring. They’re essential to the classic French mirepoix, which forms the base of soups and stews, but leeks can also be the star of the show when prepared simply, cooked whole and served as a side dish. Here are our best tips and tools for working with leeks, plus a few favorite recipes for winter and spring.


Look for: Choose leeks on the smaller side, with firm, dark green leaves and roots that are pliable and light in color. Keep them in a plastic bag in the refrigerator for up to 5 days.


Prep tips: Since they grow partly underground, leeks need more than a quick rinse under the faucet. Trim off the roots and the tough, dark green tops of the leaves. If the outer layer is wilted or discolored, peel it away and discard. Quarter or halve the stalk lengthwise. If using the leek whole, leave the root end intact. Rinse the leek well under cold running water, separating the layers and rubbing the leaves to remove any silt between them. If a recipe calls for sliced leeks, slice the white and lighter green parts crosswise. Here’s your toolkit:

Uses: Gentle cooking preserves the tender texture and flavor of leeks, so they’re often used in soups, salads and dishes with potatoes or rice. They are also served alone as a side, drizzled with vinaigrette, or cooked into quiches and gratins. Young leeks can be harvested as shoots and used raw, like chives.


Variations: Come spring, check your local farmers’ market for wild leeks, or ramps. Their bulbs have a garlic-onion flavor, and the stems are more delicate. Make the most of their super-short season by sauteing ramps whole in oil, grinding them into a pesto, simmering them in soups or pickling them.


Grilled Baby Leeks with Chervil & Chives


16 baby leeks

2 Tbs. sherry vinegar

1 tsp. Dijon mustard

Salt and freshly ground pepper

1 1/2 Tbs. minced chives

1 Tbs. minced fresh chervil or flat-leaf parsley, plus more for sprinkling

1/2 cup (4 fl. oz./125 ml.) olive oil


Trim the root ends from the leeks, leaving just enough attached to keep the leeks from falling apart.


In a rectangular glass baking dish, combine the vinegar, mustard, a pinch each of salt and pepper, 1 tablespoon of the chives, and the 1 tablespoon minced chervil. Whisk together until well blended. Add the olive oil in a slow, steady stream, whisking constantly to blend. Place the leeks in the dish and toss to coat. Cover the dish and marinate the leeks at room temperature for at least 1 hour or in the refrigerator for up to overnight.


Prepare a charcoal or gas grill for direct-heat grilling over medium-high heat. Oil the grill rack. Remove the leeks from the marinade, shaking off any excess, and reserve the marinade. Arrange the leeks on the rack and grill, turning occasionally, until tender and nicely browned, 5-6 minutes.


Transfer the leeks to a platter and drizzle lightly with some of the remaining marinade. Sprinkle with the remaining 1 1/2 teaspoons chives and with minced chervil. Serve hot, warm, or at room temperature. Serves 4.

    Hi, the article: “Ingredient Spotlight: Leeks: was excellent. It was very informative and interesting. I have spent many years working as a professional chef and found the article refreshing and reassuring. I have used leeks instead of onions and shallots because of the similar flavor and texture. I believe that leeks are truly a unique and wonderful flavor and I just love them. All of the recipes in the article are excellent and I intend to use them in the future. Thank you very much.
