Leek substitutes

Out of leek? Here are the best substitutes — what to reach for, why it works, and how much to use. Sweet onion is the top pick.

  1. 01
    Sweet onionbest pick

    Closest in sweetness and melts down the same way when softened slowly.

    1 leek = 1 small onion

  2. 02
    Shallot

    Delicate and sweet like leek, without the harshness of a yellow onion.

    1:1 by volume

  3. 03
    Scallion

    Mild allium in the same slender form; use the whites for cooking.

    1:1

  4. 04
    Onion

    Works everywhere leek does, just sharper — go a little lighter.

    use ~3/4

How we choose these

These are tested kitchen substitutes, chosen for matching flavor, texture, and role — with ratios so the swap actually works. Taste as you go; substitutes shift intensity, not just flavor.
