Steps

1. Add the thinly sliced onions to a 6 quart slow cooker. Stir in butter, brown sugar, 1 t. salt, sherry vinegar and Worcestershire sauce. Cover; cook on High 8-9 hours or on Low for 12-14 hours or until onions are caramelized and browned, stirring halfway through, as needed, to prevent burning.
