for soft yolks
Separate the eggs. Carefully place the yolks on a plate or in individual spoons. Put only the egg whites in the greased dish. Dot with butter and bake at 350 for 15 minutes. Take the whites from the oven and make 12 small divots in the whites where you want the yolks to sit. Use spoon to place each yolk on a divot. Return eggs to oven and bake 5-6 minutes more.
