Is a Leek Really a Member of the Onion Family?

Vegetables have a way of confusing us where it seems like two vegetables share similar qualities, yet they’re classified under different families. Take the leek for example. We group them together with onions and garlic, but are they really the same type of vegetable? In this article, we’ll explore what leeks actually are and how they differ from their onion relatives.

What is a Leek?

A leek is a type of vegetable that is relative to the onion, but with a sweeter and milder flavoring. Their taste is closer to that of garlic, and you can mix leeks with any type of vegetable. Leeks come in different sizes and shapes. Long, thin leeks have a milder and sweeter flavor than their larger counterparts. Leeks are native to the Mediterranean climate, where they have been used for centuries.

How is a Leek Different from an Onion?

The main difference between a leek and an onion is their tastes. Leeks, due to their subtle sweetness, make for a flavorful but milder side dish or addition to a soup. Onions, on the other hand, are much more pungent in their flavor, making them the go-to ingredient for soups, sauces, and stews. Leeks are also more tender than onions and they don’t need to be cooked as much. This can help bring out the leek’s natural sweetness.

Selecting and Using Leeks

When shopping for leeks, make sure to look for ones that are firm and with no blemishes or wilting. Their leaves should be bright green and the white part of the leek should be unblemished. When using leeks, it’s important to clean them properly, as the spaces between some of the layers can trap dirt. To clean the leeks, cut off their tops, slice them in half and rince them thoroughly with cold water.

Leeks are incredibly versatile and can be used in many dishes. They can be chopped and added to soups and stews, sautéed, roasted, and more. They can also be added to salads as a flavorful add in, used in omelettes, or made into a flavorful puree. Leeks are a wonderful way to add flavor and depth to any dish without overpowering the natural flavors of the other ingredients.
