Dry onion varieties with a distinctively light and mild flavor characteristic include white onions, often known as Allium cepa. They have a short shelf life because, like red onions, they have a high sugar and low sulphur content. Many different cuisines, including those of Mexican and European origins, employ white onions.

Both raw and cooked white onions are extremely healthy and have many other uses. White onions are rich in vitamin C, flavonoids, and phytonutrients and have potent therapeutic and medical effects.
