This smoked loaded sweet potatoes recipe takes traditional marshmallow sweet potato casserole and turns it into an individual, delectable holiday side dish!
For years we’ve sat at the Thanksgiving table filled with turkey and all the trimmings. One of the most memorable side dishes is the marshmallow sweet potato casserole. Some of us loved it, some of us didn’t. However, our smoked sweet potatoes take this traditional holiday staple to a whole new level. These sweet potatoes are smoked then topped with a delicious butter spice mixture and marshmallows at the end of cooking time. The hint of smoke sets this dish apart from its predecessor! What’s even better? They are the perfect individual portion! The key is finding the right sweet potato, and we recommend using either jewel or garnet varieties for this recipe.
