I always thought it would be tough to beat sweet potatoes with marshmallows until I read this recipe from Damaris Phillips. I have 5 words for you…mascarpone cheese and caramel sauce! That’s what makes these potatoes far superior to any others on the Thanksgiving table. These are definitely a bit extravagant but why not indulge this fall?! This Sweet Potato Marshmallow Casserole is certainly worth it!
