A smoky twist on a Holiday classic, this Grilled Sweet Potato Casserole is easily made entirely on your pellet grill. Hearty sweet potatoes are smothered in butter then smoked until soft, and stuffed with crunchy pecans, brown sugar, cinnamon and mini marshmallows. The gooey marshmallows melt into the sweet potatoes with a slight char on top for a sweet and smoky Thanksgiving or Christmas side.

Pit Boss Kitchen


  • 1/4 cup Brown Sugar
  • Butter, Softened
  • 4 oz Chopped Pecans
  • 1/2 tsp Cinnamon
  • 6 oz. Mini Marshmallows
  • 4 Sweet Potatoes

Special Tools

  • Paper Towel


  1. Fire up your Pit Boss and preheat to 400°F. If using a gas or charcoal grill, set it for medium-high heat.
  1. Wash and scrub potatoes then pat dry with paper towel.
  1. Coat outside of potatoes generously in softened butter then set butter aside. Place the sweet potatoes directly on the grill grate and smoke until soft, 1 to 1 ½ hours depending on the size of your sweet potatoes.
  1. Remove the sweet potatoes from the grill once they are tender. Coat with more butter and cover with brown sugar and Sweet Rib Rub. Slice the center of the sweet potato and press on the sides to create an opening. Stuff each sweet potato with a layer of butter, brown sugar, cinnamon, chopped pecans, and marshmallows.
  1. Return to the grill and cook, covered, for five minutes, or until marshmallows are lightly browned. Remove from grill and serve warm.
