🆚 Go to Comparative Table 🆚

Leeks and green onions belong to the same genus, Allium, but are different species and have distinct characteristics. Here are the main differences between leeks and green onions:

  • Appearance: Leeks are larger and thicker than green onions, with a single stalk, while green onions are sold in bunches. Leeks look like overgrown green onions.
  • Flavor: Leeks have a milder and more delicate flavor compared to green onions. Once cooked, leeks' flavor can be so subtle that it's hard to distinguish them as part of the onion family. Green onions, on the other hand, maintain their sharpness.
  • Usage: Leeks are commonly used in cooking, particularly in creamy soups, stocks, and other dishes that require a more delicate onion flavor. Green onions, also known as scallions, are often used in salads, salsas, and other dishes where their sharp flavor is desired.
  • Growth: Leeks can be grown from seeds or transplanted from indoor starts, while green onions can be grown from seeds, sets, or plants.

In summary, leeks and green onions are different vegetables with distinct appearances, flavors, and culinary uses. Leeks are larger and milder, while green onions are smaller and sharper in flavor.
