Green onions, also known as scallions, are a mild, fresh-tasting allium with a subtle onion flavor that adds a bright pop to dishes. They have long, slender green stalks and small white bulbs, both of which are edible. The white portion has a slightly stronger flavor, while the green tops offer a crisp, delicate bite. Green onions are often used as a garnish for soups, salads, and stir-fries or mixed into salsas, dips, and marinades. Their mild flavor and vibrant color make them ideal for adding freshness and a hint of onion flavor without overpowering dishes.
