Preparation Place the onions and butter in the insert of the slow cooker, cover, and cook on LOW for 12 to 14 hours, until the onions are deep brown and very soft. It's almost impossible to overcook these; make sure to let the onions cook until they are mahogany colored. Notes:While this recipe calls for Vidalia onions, you can use other sweet onions such as Maui, Walla Walla, or Texas 1015s. If you have a large slow cooker, you can double the onions. It is not necessary to increase the amount of butter. Don't blanch at the amount of butter called for here. When you drain and chill the onions, the onion-flavored butter will congeal on the surface of the cooking liquid. Skim it and use it when you sauté other vegetables, over pasta, or in risotto.
