Green onions (also called scallions or spring onions) are the mild, fresh allium that finishes soups, stir-fries, Korean rice bowls, Mexican dishes, and dips. The white part is sharper and more pungent; the green part is mild and grassy. Both are edible raw or cooked, but they serve different roles. Recipes on this site that use green onions include Korean Ground Beef Bowl and Taco Ground Beef Rice Bowl where green onions provide the fresh, pungent finish that balances rich or savory base ingredients.
Green onions, scallions, and spring onions are often used interchangeably in American recipes but technically differ. Scallions are the thin, young alliums with no bulb development. Green onions may have a slightly more developed bulb. Spring onions are harvested from bulbing onion varieties before the bulb fully forms and have a stronger flavor. For most recipes on this site, the terms are functionally the same ingredient. The white part has more bite and suits cooked applications; the green part is best as a raw garnish or a last-minute addition that wilts quickly in heat.
For stir-fries and Asian applications, add the white parts of green onions with the aromatics at the beginning of the cook (along with garlic and ginger) and reserve the green parts to scatter over the finished dish. The Korean Ground Beef Bowl uses this exact split technique: the white parts go into the beef saute early, and the sliced green tops are scattered over the finished bowl alongside sesame seeds and a drizzle of sesame oil, adding color contrast and a mild sharp note. Pairing with soy sauce and sesame oil in the sauce connects the fresh green onion flavor to the broader Asian flavor profile of the dish.
For raw applications like dips, salads, and potato toppers, green onions are at their best sliced thin on a slight diagonal for presentation. The Taco Ground Beef Rice Bowl uses sliced green onions as one of four finishing toppings (alongside salsa, cheese, and sour cream) that transform a seasoned beef and rice base into a fully assembled bowl. The Baked Mac and Cheese also uses sliced green onions as the optional fresh garnish that adds color contrast and a mild sharp note against the rich cheese. Browse cilantro, chives, and parsley for closely related fresh herb garnish applications.
For storage, green onions keep in the refrigerator for 1 to 2 weeks wrapped in a damp paper towel inside a bag. They can also be kept upright in a glass with a small amount of water, roots submerged, and will continue growing on the counter for several weeks. Snip from the top as needed.
In most American recipe contexts, green onions and scallions refer to the same thing: thin, young alliums with a small white base and long green stalks, harvested before a bulb forms. Spring onions are harvested from bulb-forming varieties slightly later, resulting in a small round bulb at the base and a stronger flavor. For most recipes, all three are interchangeable. If a recipe calls for a pronounced onion flavor, spring onions are the stronger choice.
Both parts are edible and useful, but they serve different roles. The white and light green parts near the base are more pungent and hold up to cooking. Add them with aromatics at the start of stir-fries and soups. The dark green tops are mild and best used raw as a garnish or scattered over a finished dish. Using both parts of one bunch of green onions is more economical and produces a layered flavor effect in the finished dish.
Place the root end of the green onion (the white part with roots attached) in a glass with about an inch of water, roots down. Set in a sunny window. The green tops will regrow within 5 to 7 days and can be snipped as needed. Change the water every few days. The roots will regrow multiple times before the flavor diminishes significantly, giving you weeks of fresh green onions from a single bunch.
Yes, in small amounts and in applications where raw or mildly flavored onion is appropriate. Green onions are much milder than yellow or white onions and will not provide the same depth in cooked dishes where onion is a foundational aromatic. For dips, garnishes, salads, and light sautees, green onions are an excellent substitute. For long-cooked braises and soups where the onion needs to fully soften and sweeten, regular onion is the better choice.
