Sweet onions are large, mild onions known for their higher natural sugar content and lower pungency compared with yellow, white, or red onions. Common varieties include Vidalia, Walla Walla, Maui, and other regional sweet onions. They have thin, papery skin that may range from pale yellow to light brown and crisp, juicy flesh. Sweet onions have a mild, delicate flavor with noticeable sweetness and less of the sharp, sulfurous bite associated with other onion varieties. They are excellent raw in salads and sandwiches, but cooking further enhances their sweetness and creates a soft, rich texture.
