Add sour cream and cheese to the sauce.
Cook, stirring constantly, over low heat until cheese melts.
Spoon asparagus into a buttered shallow baking dish. Top with cheese, onion, and sour cream mixture. In a small skillet heat the remaining butter, and when it has melted toast the Panko crumbs for about 1 minute.
