About
The Spanish onion (Allium cepa var. cepa) is a large, golden-yellow onion variety native to Spain, characterized by its thick, papery outer skin and pale yellow flesh. These bulbous vegetables typically weigh 4-6 ounces and measure 3-4 inches in diameter, making them notably larger than common yellow onions. Spanish onions possess a milder, sweeter flavor profile than yellow or white onions due to their higher sugar content and lower sulfur compounds, with a crisp, juicy texture when raw and a caramelizable sweetness when cooked.
Culinary Uses
Spanish onions are prized in both raw and cooked applications due to their mild sweetness and tender texture. They are excellent sliced thin for fresh salads, sandwiches, and ceviches, where their delicate flavor does not overpower other ingredients. In cooked applications, they excel in caramelization, soups, stews, and braised dishes; their natural sugars render deeply golden and complex flavors when slow-cooked. Spanish onions are also popular for grilling whole or halved, and are a foundational ingredient in classic Spanish cuisine, particularly in paella, tortilla española, and other regional preparations. Their size makes them ideal for stuffing and baking whole.
