Sweet Potato Gratin Casserole

This Sweet Potato Gratin Casserole is divine. It combines the healthy goodness of a sweet potato casserole with the creamy decadence of a potatoes au gratin to make a potato side dish that is both sweet and savory. The dish is layered with thinly sliced sweet potatoes and caramelized onions, and is covered with a flavorful sauce. The topping consists of a crunchy, pecan crust. This makes a terrific Thanksgiving side.
