Leeks

Buying 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.

Varieties

Leeks are a variety of onion.

Preparation, Uses, & 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.

Storing

Store leeks, refrigerated, in a plastic bag for up to three days.
