# Expert Advice:

01 -
  • The marshmallow topping caramelizes into pockets of gooey sweetness that make people actually excited about a side dish.
  • It comes together in under an hour and tastes like you spent all day on it, which is the best kind of kitchen lie.
  • Sweet potatoes are naturally creamy when cooked right, so you get that restaurant-quality texture without any fussy technique.
02 -
  • Don't skip draining the sweet potatoes thoroughly after boiling—waterlogged potatoes make the casserole taste thin and mushy no matter what else you do right.
  • Mini marshmallows toast faster and more evenly than large ones, and they actually melt into the warm casserole a little bit, creating pockets of sweetness instead of just sitting on top.
03 -
  • Use an electric mixer if you have one—it creates an airier, more luxurious texture than hand mashing, and it's less work when you're juggling a crowded kitchen.
  • Toast your pecans lightly in a dry pan before adding them; it wakes up their flavor and makes the whole casserole taste more intentional and professional.
