Sweet Potato Casserole with Toasted Marshmallow Fluff
It might be the greatest debate on the Thanksgiving table — to add marshmallows or to skip the fluff. This Sweet Potato Casserole is made with a homemade marshmallow fluff topping that can be added to the make-ahead individual servings or skipped for those non-fluff fans.
I recommend using a kitchen torch to toast up the marshmallow topping tableside for serving. It’s interactive fun for Thanksgiving, and it just might talk convince the anti-marshmallow crowd that this dish isn’t complete without the campfire topping.
