In This Recipe

Consider the leek.

It's majestic, a titan in the onion family.

Mostly just the white and light green parts are eaten, though the darker green parts have plenty of flavor and can either be cooked longer to tenderize them, or used when making homemade soup stock.

Leeks Are Dirty

The challenge when cooking with leeks is that they are almost always dirty. When leeks are grown, soil is piled up around them, so that more of the leek is hidden from the sun, and therefore lighter in color and more tender.

What produces a beautiful leek, a long pale body, also results in sand and dirt being lodged deep inside the leek.

Two Ways to Clean Leeks

There are basically two ways to clean leeks, the method you use depends upon how you are going to use the leeks in cooking. The easiest way is to prepare them chopped for use in soup.

A little more challenging is preparing a leek for use in a recipe that requires whole leeks. Both methods are detailed here.

Preparing leeks for soup

  1. Remove the roots and slice:

    Cut off the roots of the leeks. Slice the leeks lengthwise.

  2. Make crosswise cuts:

    Decide how much of the leek greens you want to use. They are tougher and can be stronger tasting, but soften with long cooking.

    The last couple of inches of the dark green ends should probably be discarded or saved for making stock. (I put mine in a plastic bag and drop it in the freezer.)

    Make crosswise cuts along the parts of the leek that you intend to use.

  3. Rinse in a bowl of cold water:

    Place the chopped leeks into a bowl and fill with cold water. (If the leeks are especially dirty, rinse them first in a colander, before covering with water.) Use your hands to agitate the leeks and dislodge any dirt or sand that may be clinging to them.

    Scoop the leeks out of the water with a sieve or slotted spoon and place in a new bowl.

Cleaning and prepping whole leeks

  1. Cut from opening to ends of greens:

    Place leek on a cutting board. Insert the tip of a sharp knife about a 1/4-inch below the lowest opening in the leek.

    Cut straight through, up to and through the green ends of the leek, leaving the pale part of the leek whole.

  2. Rinse:

    Fan open the leek and place under cold running water. Rinse out any dirt or sand. If the leek is especially dirty, you may want to make another similar cut through the leek to further be able to fan the leek open.

  3. Cut off dark green tops:

    Cut off the dark green tops of the leek, reserving on the body of the leek as much of the dark green as you want. We like the taste (it's basically just a big onion green), so we typically keep about 2 to 3 inches or so of the dark green part with the body of the leeks.

    This Is the Absolute Easiest Way to Clean Leeks (15)

    Discard the dark greens or save them to flavor soups or stews, or use for making stock.

  4. Cut of the root end of the leeks:

    Stay as close to the roots as possible. Cutting close to the roots will hold the leeks together when cooking them whole.
