White onion (Allium cepa, 'sweet onion') is a cultivar of dry onion, that has a pure white papery skin and a sweet, mild white flesh.[1]

Similar to red onions, due to the high sugar content, they have a short shelf life, lasting up to 2 days, or if refrigerated, they can last up to a month.[2]

This onion is used in Mexican foods or complementing the flavors of other ingredients.

The onion can be sautéed to a dark brown color and served to provide a sweet and sour flavor to other foods. Small white onions used in soups,[3] casseroles or stews, they are known as 'boiler onions'.[4][5][6] They can also be added to salads.[1]

Known sweet white varieties include; 'Walla Walla', 'Vidalia' and 'Mauri'. White storage onion types include; 'White Wing' and 'Sierra Blanca'.[2]
