This is my tweaked version of a recipe taken from my very old and well worn copy of The Good Housekeeping Cookbook. This is said to be a very old and traditional recipe in Belgium. I think it has the best flavor when a dark beer is used. Also, the original recipe I have called for 8 large onions. I scaled the onions back a bit! Carbonnade of Beef is delicious served with cooked noodles, hot cooked rice or mashed potatoes.
