This is so delicious that everytime I make it I wish I used more onions than I did because caramelized onions have so many uses! They're great as a topping pizza or pasta dishes, over steak or pork chops, in French onion soup, mashed up with potatoes or in an onion dip. You can also make this with shallots, too. But, be careful not to burn it for obvious reasons!
onions, peeled, and sliced thinly
butter or oil
Saute onions in butter or oil over medium low heat in a heavy bottomed pan until they turn a deep golden brown and are super sweet and soft. Keep stirring and turning the heat down as needed to keep them from burning. The process usually takes me about 45 minutes.
