A yellow onion is a round, papery-skinned bulb with pale yellow-white flesh. It has a sharp, sulfurous bite when raw that cooks into deep sweetness and a jammy softness. Reliable and versatile, it forms the backbone of sautes, stews, and braises, and holds up to roasting, grilling, and caramelizing. Sold mainly whole in various sizes, also available pre-chopped.

Domesticated from wild alliums in Southwest and Central Asia, storage-type yellow onions spread through Europe and into North America. They anchor classic French, Mexican, and Indian cuisines, and are bred for firm bulbs with long keeping quality.
