Leeks are in season from late fall to early spring, but they can be hard to find at other times of the year. If you’re looking for a leek substitute, there are a few things to keep in mind. Here are some tips on how to find the best leek substitutes.
But before we can find out what is the best replacement for leeks, we need to under what they taste like. This helps us figure out the best swap!
What Do Leeks Taste Like?
Leeks are a vegetable with a mild, onion-like flavor from the Amaryllidaceae family. Their taste is savory and slightly sweet and can vary depending on how the leek has been cooked. For example, when sautéed, leeks will provide a subtle nutty flavor with a hint of sweetness that comes from the caramelized ends.
Similarly, when steamed, leeks will remain quite mild in taste with an underlying sweetness. Roasting is also great for increasing the depth of flavor of this vegetable.
Leek Substitutes That Work
All the onion options below can be used for a one-to-one ratio. This means if a recipe calls for one cup of chopped leeks, one cup of these onions can be used as a replacement.
Green Onions and Scallions
Green onions are a great substitute for leeks and can be used in a similar way. Green onions have a more intense flavor than leeks, but they will still provide the depth of flavor you are looking for.
Green onions, also known as scallions, are a popular open-pollinated vegetable belonging to the Allium family. They have a mild onion flavor and long, thin green stalks and white bulbs. They look like a baby leek!
Green onions have an extended growing season as they can be harvested during any stage of maturity. Use them raw in salads or cooked in stir-fry dishes (great in Asian cuisine) and soups. Green onions are packed with vitamins A, C, and B-complex vitamins, making them a very healthful addition to any meal.
Shallots are also an ideal alternative to leeks when making soups, stews, and sauces. They have a milder onion flavor with some garlic flavor as well. This is because Shallots are also a type of plant in the Allium family, closely related to both onions and garlic.
They grow in an onion-like shape and have thin, papery skin with pinkish-brown or gold coloring, depending on the variety. Shallots also contain compound sulfur sulfides that promote good health and are being studied for potential cancer prevention qualities.
Sweet Onions are a type of onion boasting a mild and slightly sweet flavor and low on that pungent strong flavor that onions tend to have. As such, they are popularly used in both cooked and raw preparations, adding a unique flavor and crunch to salads, sandwiches, side dishes, and more. I personally love adding them to a spinach and strawberry salad.
Although they can appear similar to other types of onions at first glance, sweet onions have an edible skin that is less fibrous than many other varieties; plus, their high sugar content prevents the strong bite from developing. Notable “sweet onion” cultivars include Maui Sweets from Hawaii, Vidalia Onions from Georgia, and Walla Walla Sweet Onions from Washington.
Because of their sweet flavor, these can work well as a leek substitute. Plus, sweet onions are easy to find and are usually affordable.
Ramps (Wild Onions)
Ramps, or wild onions, are a species of wild leek found in Northwestern and Northeastern parts of the United States. They usually grow in clumps beneath deciduous trees and have a pungent garlic-like aroma. Ramps typically have slender green leaves with broad white bulbs that vary in size.
This substitute for leeks might be hard to find, but if you happen to have them growing wild or know where to get them, you are in for a real treat.

What About Other Onions?
There are several types of onions that are common at the grocery store. And it could be that you have white or red onions in your pantry and none of the options I mentioned above. Will they work as a replacement for leeks? Yes, even though they are a more robust pungent onion, they can still be used. Just know that the flavor of the overall dish will be slightly different. Here is a list of different types of onions:
1. Red onions
Red onions are a type of onion that is characterized by its red skin and white flesh. Red onions are relatively mild in flavor and are often used in salads or as a garnish. These onions are also great for making sweet pickled onions. One of my favorite things and super easy to make.
2. Yellow onions
Yellow onions are a type of onion that is characterized by its yellow skin and white flesh. Yellow onions are slightly more pungent than red and are often used in cooking. They caramelize wonderfully; even Foodnetwork agrees!
3. White onions
White onions are a type of onion that is characterized by its white skin and white flesh. White onions are the most pungent and sharp of all the onion varieties and are often used in Mexican dishes. They are usually enjoyed raw and cooked.
4. Sweet onions
We have gone over sweet onions early, but sweet onions are a type of onion that is characterized by its sweet flavor and low sulfur level. Sweet onions are often used in salads or as a garnish.
5. Pearl onions
Pearl onions are a type of onion that is characterized by its small size and round shape. Pearl onions are often used in stews or soups or roasted. They are sweeter and milder than their larger siblings in the onion family.
Shallots deserve to be mentioned again. They are a type of onion that is characterized by their small size and elongated shape. Shallots have a milder flavor that leans on both onion and garlic. They work wonderfully in sauces, gravies, vinaigrettes, marinades, and many other applications.
