Leek

What Is Leek?

Leek (Allium ampeloprasum), from the onion family, is a winter vegetable known for its long white stalk and dark green leaves. It's a relative of onion and garlic, but its smell and taste are much milder.

The white stalk is the most preferred part; the green leaves are tougher but can still be used in soups. It's cold-hardy, and winter is its most flavorful season.

This information is general; leek is a food, not a substitute for medical treatment.

How to Choose Leek

Fresh leek has a firm white stalk and vivid green leaves; yellowed or softened stalks are a sign of staleness.

• The white-to-light-green transition zone should be long; this shows the stalk is more tender.
• The stalk should feel firm and crisp when squeezed by hand, not spongy and soft.
• The root end should look moist, and the cut surface should look fresh.

How to Store Leek

Leek stays fresh in the fridge for 1–2 weeks in a loose bag, standing upright. Chopped leek can be frozen for a few months; however, since its texture softens, it's best used in cooked recipes.

Using Leek in the Kitchen

Leek is used as the main ingredient in olive-oil dishes, as a flavor base in soups, and as a complement in ground meat dishes. Since soil collects between its layers, it should be split lengthwise and washed under plenty of water.

How to Clean Leek

After the root and the dark green ends are cut off, the stalk is split lengthwise and the layers are washed open under running water. This method fully removes the soil trapped between the rings.

What Recipes Is Leek Used In?

Leek with olive oil, leek soup, leek with ground meat, and leek gratin are among the most beloved recipes. It's also often used as a flavor base in vegetable sauces.
