Onions are used worldwide as a base for many dishes because of the luscious flavor they impart. Their taste ranges from raw and pungent, to sweet and tasty, and they are often sweated to transparency or slightly browned until caramelized.

Onions are prized and included in many southern recipes. Southerners include it in their dips and salads, meat and chicken dishes, even fish and beef entrees. One of the most famous southern casserole recipes you can find is the Southern Vidalia Onion Casserole. It boasts of a creamy texture and cheesy flavor that is heavily loaded with sweet onions and topped with buttery crackers. It is a perfect match for ham, pork chops, burgers, and steaks.

Vidalia Onions

In the United States, Vidalia Sweet Onion was first discovered growing in Toombs County, Georgia in 1931. The farmer, Moses Coleman, did not know that he was growing Vidalia Sweet Onions until he harvested them and discovered that they were sweet, instead of hot and pungent. Locals took a liking to the sweet flavor of Vidalia Onions and by the 1940’s the State of Georgia built a farmer’s market to sell this onion variety.
