Sweet potato casserole walks the line between side dish and dessert, and this version does it gracefully. Roasting the sweet potatoes instead of boiling them concentrates their natural sweetness and gives the filling a deeper, almost caramelized flavor, so it needs only a modest amount of added sugar.
The potatoes are whipped with butter, eggs, a little cream, vanilla, cinnamon and nutmeg into something smooth and souffle-light. Then comes the best part: a thick, crumbly pecan streusel that bakes into crunchy, buttery clusters.
It is a holiday essential, perfect alongside roast turkey or glazed ham, and because both components can be prepared ahead, it is a stress-free addition to any big-dinner menu.
