      1. About Leeks

      A relative to onions and garlic, leeks are prized for their mild, slightly sweet flavor. Though they look like overgrown spring onions, leeks are a unique vegetable. They go great in potato soup or leek tarts, and cooked leeks make a delectable side dish. They can even be used to make a raw leek salad.

      Traditionally, leeks have grown throughout Europe and Central Asia. However, they have now spread across the Northern Hemisphere. 

      In many places, leeks have cultural significance. Remains of leeks have been found in Egyptian tombs dating back thousands of years. They were also a staple of ancient Roman cooking, where they were renowned for their alleged medicinal properties. Emperor Nero was even said to consume leek soup daily because he thought it would improve his singing voice. 

      At some points in European history, leeks were even more popular than their cousins, onions, and garlic. They were so highly prized that kings even paid their servants in leeks. 

      According to legend, when Welsh King Cadwaladr fought the Saxon army in the middle ages, he told his soldiers to put leeks in their hats so they could identify each other on the battlefield. Leeks have been a symbol of Wales ever since.

      Leeks are so strongly associated with Wales that Queen Elizabeth II’s coronation dress featured embroidered leeks studded with diamonds to represent the country – against the best judgment of the designer, who was irked that he had to include a vegetable rather than a flower. To this day, the prestigious Welsh Guards division of the British Army wears leek badges on their ceremonial uniforms.

      Now, while leeks are not necessarily as common in cooking as they have been throughout history, they are still beloved among chefs as an alternative to the harsher flavor of regular onions. Their mild flavor is a great addition to soups, like the classic leek and potato soup.

      Cook them in a wok with pork, soy sauce, and a pinch of salt for a delectable stir fry, or sauté them in butter and serve them as a side. Once you get used to cooking with leeks, get experimental – add them to dishes like chicken noodle soup or try eating raw leeks. 

      2. How To Cut Leeks

      Fresh leeks can be found at grocery stores and farmer’s markets. Select leeks with plenty of white or light green along the stalk to get the most out of the vegetable. To ensure that they are fresh, check to make sure that they haven’t started to yellow or turn soft. Fresh leeks should be firm and not withered or bruised. 

      Before cutting your leeks, select a sharp chef’s knife. Be sure to have a cutting board and a colander handy, too. 

      Despite their similarities, cutting a leek is a little different from cutting an onion. Since leeks grow buried in sandy soil, which often becomes trapped between layers, you need to be especially careful when washing them. 

      First, rinse your leeks in cool water and pat them dry with a paper towel. Be careful, but keep in mind that you’ll be cleaning them again later. Next, place the clean leeks on your cutting board and slice off the roots and the leafy green tops. If you see any tough-looking outer leaves, pull them off. 

      If your recipe calls for smaller slices, slice the leeks in halves or quarters lengthwise first. Alternatively, for complete circles, leave them whole. 

      One important knife skill to mention is holding your leek steady with one hand, fingers curled under for protection while slicing it with the other. Consider how thick you want your leeks – would you rather have big chunks or delicate slices? 

      Some leek recipes may call for leeks to be cut in the julienne style. Julienne style refers to vegetables cut into long thin slices, lengthwise. To cut leeks in the julienne style, remove the green tops and the roots. Then, cut the vegetable in half lengthwise, and slice the leek halves into thin strips.

      You’re not done yet, though! You’ll need to wash them again before cooking them. Place your diced leeks in a colander or large bowl and rinse them one last time in cold running water. Be thorough to ensure that no sand or dirt remains. Finally, your leeks are ready to cook! 

      Once you’ve sliced your leeks, use them immediately or store them for a few days in an airtight container in the refrigerator. You can also try freezing chopped leeks for later use.

      While exactly how to use your sliced leeks is up to you, consider options like potato leek soup, sautéed leeks, or roasted leeks with olive oil.

              4. Frequently Asked Questions

              paring knife cutting a leek down the middle on a black cutting board

              What part of the leek do you cut?

              When cutting leeks, cut the white and light green parts of the vegetable and toss the roots and dark green leaves. Make sure not to cut too far up – while the leek greens are edible, they’re bitter.

              Can you use the green part of the leek?

              The dark green leaf is tough and has a bitter flavor, so you shouldn’t use them in your favorite leek recipes. However, the leaves can be used to make vegetable stock for soups.

              How much of a leek do you trim? 

              Trim the leeks before the green leaves start to branch out. Many leeks have a fairly distinct line where the light green part of the vegetable shifts to a darker shade. 

              Do I have to clean leeks?

              Cleaning leeks is an essential part of cooking since dirt gets into the crevices of the leaves quite easily.
