Leeks

Fresh leeks

How to select

Choose firm, crisp stalks with as many white and light green regions as possible. Avoid leeks with yellow or withered tops.

How to prepare

  • Cut off the roots and coarse, dark green tops (these can be saved and used for stocks). 
  • Cut each leek in half lengthwise. 
  • Wash under running water being sure to get in between layers. 
  • Drain and cut as desired.

How to store

Refrigerate unwashed leeks in a plastic bag for up to two weeks. Rinse before using.

Ways to use

  • For a slightly different flavor, add leeks to soups or stews at the same cooking stage as you would onions.
  • Add leeks to your mashed or scalloped potatoes. To mash: dice the white part of 2 leeks and add to the potatoes as they begin to boil. To scallop: layer them into your favorite recipe.
  • Dice or thinly slice leeks then sprinkle these onto a salad or soup for an attractive (and nutritious!) garnish.
  • Add a delicious and unique flavor while cooking your beans by tossing in some sliced leeks.

Fun facts

  • Leeks are members of the genus Allium, which includes onions and garlic.
  • Hippocrates, the ancient Greek physician and ‘father of medicine’,  prescribed the leek as a cure for nosebleeds.
  • Leeks have been cultivated since the time of the Ancient Egyptians and were probably eaten by the people who built the pyramids.
