The Walla Walla Sweet Onion is a unique variety of onion known for its mild flavor and high sugar content. Grown in the Walla Walla Valley of Washington State, these onions thrive in the region's rich volcanic soil and favorable climate. They are typically harvested in late spring and early summer, making them a seasonal favorite. These onions are characterized by their large size and pale yellow skin. Due to their sweetness, they can be enjoyed raw in salads or on sandwiches, and they caramelize beautifully when cooked. The Walla Walla Sweet Onion has even been designated as a Washington State agricultural treasure.
