Leeks

Discover simple tips to unleash leeks’ mild onion flavor

Best to buy
Leeks are available all year long, and peak in the fall and winter.

Cut & clean
Cut off roots, slice lengthwise from top to bottom, and run leeks under cold water with green end facing down to remove dirt from leaf layers.

A new twist
A cousin of the onion, leeks can be substituted in any dish.

Super for stock
Use the stalk's tough green portion to add flavor to stock or broth.

Power food
Leeks are a good source of iron, vitamin C, and folic acid.


Preparation, uses, and tips

Trim the roots from the base of the stalk. Slice leeks lengthwise, from top to bottom, and hold under cold running water with the green end facing down to remove dirt and fine sand trapped in leaf layers. Discard the tough green portion of the stalk unless using it to add flavor to stock or broth. Slice the white portion and sauté with chopped portobello mushrooms and minced garlic, or add to soups and stir-fry dishes.

Buying and storing tips

Leeks are available all year long, and are at their peak in the fall and winter. Choose those with bright green leaves, avoiding any with wilting or yellowing leaves. Smaller leeks tend to be more tender. Store leeks, refrigerated, in a plastic bag for up to three days.

Varieties

Leeks are a variety of onion.
