Running low on leek? Here are the best verified substitutes, including how to adjust your measurements.

About leek
Leeks are a mild-flavoured allium vegetable with a thick, cylindrical white stalk and dark green leaves, belonging to the same family as onions and garlic. They have a sweeter, more delicate flavour than onions, making them ideal for soups, stocks, quiches, and braises where a subtle onion presence is desired. The white and light green portions are most commonly used in cooking, while the tougher dark green tops are often reserved for stocks.
Best substitute
Brown onions provide a similar allium flavour base and are the most accessible substitute, though they are sharper and more pungent than leeks. Use them raw or sautéed gently to soften their bite before adding to dishes.
Alternative
Spring onions (scallions) share a similar mild, sweet allium flavour and are an excellent leek substitute, particularly in dishes where a delicate taste is important. Use the white and light green parts for the closest match; larger quantities are needed as spring onions are much smaller.

Fennel has a similarly mild, slightly sweet flavour with a subtle anise note that works well in soups, braises, and roasted dishes as a leek substitute. Slice thinly and cook until softened; the anise flavour mellows considerably with heat.
Alternative
Shallots offer a sweeter, more refined flavour than brown onions and are closer to leeks in terms of mildness and complexity. They work particularly well in cream-based sauces, quiches, and gratins where a gentle allium flavour is required.
Alternative
Celery provides a mild, aromatic base note and similar bulk to leeks in soups, stews, and stocks, though it lacks the allium character entirely. It is best used in combination with a small amount of onion or garlic to approximate the flavour profile of leeks.
