  • 6 medium sweet potatoes
  • 2 tablespoons olive or vegetable oil
  • 1 tablespoon coarse salt
  • 6 tablespoons butter softened (not melted)
  • 6 tablespoons packed brown sugar
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon powdered ginger
  • 1/4 teaspoon ground nutmeg
  • 1 1/2 cups mini marshmallows
  • 1 large disposable aluminum pan or smoker friendly metal sheet pan


  • Preheat smoker or grill for 275 degrees F.
  • Wash and gently scrub sweet potatoes under lukewarm water—dry well with paper towels.
  • Lightly puncture the peels with a fork. Coat each potato will oil and salt.
  • Place sweet potatoes into your grill or smoker, close the lid, and cook for 1 1/2-2 hours, or until they are fork-tender.
  • Remove potatoes from the grill and place them onto a large cutting board. Increase the heat of your grill or smoker to 475 degrees F.
  • Combine softened butter with brown sugar, cinnamon, ginger, and nutmeg.
  • Slit each sweet potato down the center lengthwise. Avoid cutting them all the way through. Use the above picture as a guide.
  • Scoop equal portions of butter mixture into each sweet potato, and top with 1/4 cup of mini marshmallows.
  • Arrange sweet potatoes into a large smoker safe pan, marshmallow side up.
  • Once your smoker (or grill) has reached 475 degrees F, place the pan with the sweet potatoes on the grill grates. Close the lid and broil them for 3-5 minutes, or until the marshmallows have browned and softened.
  • You can also broil the smoked sweet potatoes using your oven.
