Ruth's Chris Sweet Potato Casserole is so good and the only way to go as far as sweet potatoes are concerned. Creamy and delicious, these sweet potatoes are topped with a brown sugar streusel pecan crust. This casserole could easily be dessert—maybe even with a scoop of ice cream! You can make these ahead—up to a couple of days in advance and then bake the crust for 10 minutes before serving. It makes an amazing side dish to any holiday meal!
