Leeks (Allium ampeloprasum) belong to the Allium family, which also includes onions, garlic, shallots, and chives.

Leeks have been cultivated for thousands of years and were a popular vegetable in ancient Egypt, Greece, and Rome.

How to Use Leeks

Leeks are incredibly versatile in the kitchen and can be used in various culinary applications:

Cleaning Leeks

Before using leeks, it’s crucial to clean them thoroughly. Because of how they grow, dirt and sand can get trapped between the layers of leaves. Here’s how to clean them effectively:

  1. Trim: Cut off the roots and the dark green portion of the leaves (the dark green part is often tough). Discard the roots, but you can save the dark green leaves for making stock.
  2. Slice: Slice the white and light green parts lengthwise down the middle, stopping just before the root end to keep the leek intact.
  3. Rinse: Hold the leek under cold running water, fanning the layers to remove any trapped dirt and grit. Alternatively, you can slice the leeks into rounds and wash them in a bowl of cold water, allowing the dirt to settle before scooping the leeks out.
  4. Dry: Pat the leeks dry with a clean kitchen towel or paper towels.

Cooking with Leeks

  • Soups and Stews: Leeks add a subtle, savory flavor to soups and stews. Try adding them to potato soup, chicken soup, or vegetable stew.
  • SautĂ©ed Leeks: SautĂ©ed leeks make a delicious side dish. Simply slice the leeks, sautĂ© them in butter or olive oil until tender, and season with salt, pepper, and herbs.
  • Quiches and Frittatas: Leeks add a delicate onion flavor to quiches and frittatas. SautĂ© them before adding them to the egg mixture.
  • Roasted Vegetables: Toss leeks with other vegetables like carrots, potatoes, and Brussels sprouts, and roast them in the oven for a flavorful and nutritious side dish.
  • Leek and Potato Soup (Vichyssoise): A classic cold soup made with leeks, potatoes, cream, and chicken stock.
