scallions / spring onions

Scallions, also known as spring onions, green onions, or Welsh onions (Allium fistulosum), are young bulbing or non-bulbing onion varieties harvested before full maturity. Native to central and eastern Asia, they are characterized by long, slender green leaves and white to pale green bases with minimal bulb development. The entire plant—both the tender white bases and crisp green tops—is edible and prized for its mild onion flavor with subtle sweetness. Unlike mature onions, scallions lack the pungent sulfur compounds, making them delicate enough for raw consumption while still contributing onion notes to dishes.

Different regions produce distinct cultivars: Japanese varieties tend toward longer, thinner bulbs with more pronounced white sections, while American and European types often have less-developed bases. The flavor profile is herbaceous and fresh, with white portions offering slightly more pungency than the tender green tops.

Scallions function as both a delicate flavoring agent and a vegetable in cuisines worldwide. In East Asian cooking—particularly Chinese, Japanese, and Korean traditions—they are essential aromatics used raw as garnishes, incorporated into dumplings, and cooked into stir-fries and noodle dishes. Western cuisines employ them as a fresh finish for soups, baked potatoes, and cream-based dishes, while Latin American and Caribbean kitchens feature them in sofrito bases and ceviches.

The vegetable's versatility stems from its dual-zone structure: white bases are minced into soffritto-style foundations or pickled for condiments, while green tops remain crisp when added at the last moment, providing visual appeal and fresh bite. Raw scallions appear in Asian dipping sauces, salads, and as a textural contrast, while gentle cooking softens them for incorporation into cooked dishes without destroying their delicate character.
