4 large sweet or yellow onions
1/4 lb. butter (not margarine)
Recipe
In a large crockpot, place peeled whole onions and trim top and bottom slightly. Add whole stick of butter - no need to cut. Cover and slow cook for 12 hours on low heat... will literally fall apart, deep, sweet caramelization, easily chopped.
Notes: I use Vidalia's when they are cheap... Texas or Florida sweet onions work pretty well too! You won't be able to stop eating these... they are really, really deeeeee-lishus! Just this recipe alone is enough reason to own a crockpot!
