Combine the oil, butter, and minced onion in a large saucepan or skillet. (Don't melt the butter first--you want everything to cook together.) Set over a VERY low flame, cover, and cook 35-40 minutes (possibly longer; it's question of color and texture), stirring occasionally. Basically you want them to be very, very soft--not much crunch--and deeply, deeply golden, but not browned or burnt, hence the low heat.
