Grilled Up Sweet Potato Casserole

I absolutely love sweet potato casserole and can hardly wait until the holidays to begin baking it. This version can be done on the grill in less than 30 minutes! Large sweet potatoes may require more cinnamon-sugar topping ingredients. Add more mini marshmallows before serving if desired. —Norma Conley, Richmond, Kentucky

  • Peel and cut potatoes into 1/2-in. slices; transfer each potato to individual pieces of heavy-duty foil (12-in. square). Cut butter into thin slices; place between potato slices. Sprinkle with cinnamon, brown sugar and pecans. Fold foil around potatoes, sealing tightly. Grill, covered, over medium heat or broil 4 in. from heat until potatoes are tender, 18-22 minutes, turning occasionally.

    Easy way to enjoy sweet potatoes when we go camping. Enjoyed these with marinated grilled steak and a salad. Will definitely make again. Gave 4 stars because mine were a little too dry... will try more butter, and moving the packs onto the grill top rather than in the coals.
