Spanish onions are medium to large in size, averaging 5-10 centimeters in diameter and are globular in shape with rounded to slightly tapered ends. The bulb is encased in a light yellow to copper, dry, papery skin. The flaky, layered skin surrounds a white to cream-colored translucent flesh. The ringed flesh is firm, crisp, and juicy. Spanish onions are crunchy with a pungent flavor when raw, and when cooked, they develop a nutty, mild flavor with sweet undertones.
Spanish onions are available year round.
