These Ruth's Chris Sweet Potato Casserole is creamy and topped with a brown sugar pecan crust just like they are at Ruth's Chris Steakhouse.
Note: 3 cups sweet potatoes is about 3-4 large sweet potatoes. To cook sweet potatoes first wash and dry them carefully then you can either: 1) Bake them at 400 degrees for 50-60 minutes (my preferred method) 2) Boil them for 30 minutes or 3) Pierce them with a fork and microwave them for about 15-20 minutes.

The size of dish will depend on how thick you want your potatoes. I like to use around a 2 quart dish. A 9x13 pan is a 3 quart dish so if you're doubling it and put it in a 9x13 it might be on the thicker side.
