• Pour cream over potatoes, pushing them down to make an even layer (cream should just cover potatoes; add more if necessary). 

1. Sprinkle with nutmeg, then dot with remaining 2 table spoon butter. Cover the dish with foil and bake 30 minutes. Remove the foil and bake until top is golden and potatoes are tender, 35 to 45 minutes more. Let rest 10 minutes before serving.
