What Is Green Onion?
Green onion (Allium fistulosum), from the lily family, is a vegetable-herb with a slender white stalk and hollow green leaves. It has a much milder, fresher, less pungent flavor than a mature dry onion.
Both the white stalk and green leaves are edible; the white part has a sharper flavor, while the green part tastes milder and more herbaceous. In Türkiye, green onions are often eaten raw at breakfast; in cuisines around the world, they are also commonly used in sautés and soups.

What Are the Benefits of Green Onions?
With their high vitamin K content, green onions are among the greens that stand out as part of a balanced diet. Research continues on the sulfur compounds they contain, as in other members of the Allium family; these studies have not yet led to a general health recommendation.

How to Choose Green Onions
A bunch of fresh green onions should have bright green leaves and firm, fresh white stalks.
- The green leaves should be vibrant and upright; yellowing and wilting are signs of age.
- The white stalk should be firm and smooth, not soft.
- If roots are present, they should look moist and white.
How to Store Green Onions
Green onions stay fresh for 1 week when stored upright in the refrigerator with their roots immersed in a glass of water or in a damp bag. For longer storage, they can be finely chopped and frozen in a freezer bag; they can be used directly in soups and other dishes.
How to Use Green Onions in the Kitchen
Green onions are used raw in salads and at breakfast, and cooked in sautés and soups. Since the green part loses its crispness and vivid color when cooked, it is added near the end of cooking or just before serving in most recipes.
How to Cut Green Onions
Separate the white and green parts and slice them into thin rings; add the white part at the beginning of cooking and the green part at the end or just before serving. This distinction preserves the balance of texture and aroma.
What Recipes Use Green Onions?
Green onion omelets, green onion soup, Asian-style sautéed vegetables, and green onion salad are among the most popular uses. Green onions are also added to meatball and mantı (Turkish dumpling) fillings.
