Compared to storage onions, sweet onions have slightly higher sugar and lower sulfur, which softens pungency. Their higher moisture means they cook down quickly and caramelize readily.

Storage

Room temp: up to 7 days
Refrigerated: up to 14 days

A sweet onion is a large, pale yellow to white bulb onion with thick, juicy layers. It tastes mild and sweet with a crisp snap when raw, and turns tender and mellow when sauteed or roasted. Use it for quick sautes, caramelizing, batter-frying rings, and raw applications like salads and sandwiches. Sold loose or in bags, often labeled by variety.

Modern sweet onions were developed in the U.S. South and Pacific Northwest from low-pyruvate cultivars; notable types include Vidalia (Georgia), Walla Walla (Washington), and Maui (Hawaii). They are grown in well-drained soils and harvested in spring to early summer, then marketed quickly as short-storage onions.
