There are many ways to order potatoes from the Ruth's Chris menu including steak fries, julienne fries, shoestring fries, cottage fries, Lyonnaise, baked and au gratin. Here's a traditional, classic recipe for the delicious side dish inspired by the Ruth's Chris creation. You may use less of the cream and milk mixture in your version depending on the size baking dish you use and the size of your potatoes. Stop adding the creamy mixture in your version when it is level with the sliced potatoes in the baking dish. Be sure to use a casserole dish that has a lid for the first stage of baking.
