white onion diced

The white onion (Allium cepa var. cepa) is a cultivar of the common bulb onion characterized by pale white papery skin and white flesh with mild to pungent flavor. Native to Central Asia and domesticated for millennia, white onions are cultivated globally and are smaller and sweeter than yellow onions when raw, though they sharpen noticeably when cooked. Key varieties include Bermuda, Egyptian, and Spanish white onions. The white variety contains sulfur compounds responsible for the characteristic onion aroma and tear-inducing properties when cut; these compounds transform into sweet, caramelized notes during cooking.

White onions are staple ingredients in numerous world cuisines, particularly in Latin American, Asian, and Mediterranean cooking. They are commonly diced for salsas, guacamole, ceviche, and fresh salsas cruda where their mild raw flavor is prized. When cooked, diced white onions are essential for building flavor bases in soups, stews, stir-fries, and curries. They are particularly favored in Mexican cuisine for tacos, enchiladas, and pozole, and in Asian cuisines for pad Thai and other stir-fried dishes. Diced white onions integrate quickly during cooking and caramelize to golden sweetness, making them ideal for both quick sautés and slow-braised applications.
