This sweet potato casserole with marshmallows is gooey and delicious! It's a family favorite for holidays that you can bake ahead and reheat.
For a richer, deeper flavor profile, consider roasting the sweet potatoes instead of boiling them; this caramelizes their natural sugars more effectively. Ensure potatoes are exceptionally well-drained after boiling to prevent a watery casserole base. To elevate the mash, incorporate a tablespoon of browned butter or a touch of fresh orange zest for a brighter, more aromatic dimension. During the final bake, closely monitor the marshmallows to avoid burning; a quick broiler finish for the last minute can achieve a perfect golden crust. For an added layer of complexity, blend in a pinch of fresh grated nutmeg or a whisper of ground ginger with the cinnamon.
