Nutrition Information

Leeks are known for being rich in vitamins A, C, and K, and minerals like folate and manganese. They also contain dietary fiber, which aids in digestion and helps promote a healthy gut.

When buying, storing, and using leeks, a few key considerations can ensure their optimal freshness and flavor.


How to Buy Leeks

Whether you buy leeks at the grocery store or farmers market, look for straight, firm, crisp stalks with vibrant green leaves and an unblemished outer layer. Avoid wilted or yellowing leaves, brown spots, and slimy or discolored parts. You will also want to avoid bulging bulbs.

Be sure to bend the stalk’s lower part to make sure it has “give.” If it doesn’t bend easily, the leek is probably woody and won’t soften as much when cooked.


Once you bring your leeks home, remove the rubber bands or ties and trim the root ends. Leeks can be stored in the refrigerator, wrapped loosely in a damp paper towel, and slipped into a plastic bag for up to one week.

After you cook a leek, this vegetable will only keep for about 2-3 days in the refrigerator. Leeks can be frozen, but their flavor and texture are altered when thawed.

Cut this vegetable into slices before freezing. You can also blanch them for 2 minutes before freezing. Use them within three months for best results. For maximum flavor, you can cook them without thawing them out.


When using leeks in recipes, cleaning them thoroughly is crucial, as dirt and sand often get trapped between their layers. Trim off the roots and the green tops, leaving a little green if desired. Remove any wilted outer leaves. Slice the leeks lengthwise and pry open the layers of leaves. Rinse them under cold running water, ensuring all the grit is removed. Drain.
