For a crunchy topped sweet potato casserole...

Omit marshmallows and reduce brown sugar in sweet potato mixture to 1/4 cup.  Before baking, combine 3/4 cup all-purpose flour, 3/4 cup packed brown sugar, 3/4 cup chopped pecans and 1/2 cup melted butter in a small bowl.  Sprinkle over the mashed potato mixture.  Bake, uncovered, at 350 degrees for 50-55 minutes or until heated through and topping is browned.
