German Baked Fish au Gratin – Oma's Überbackener Fisch mit Kase

Baked Fish au Gratin is a favorite German dinner. The French "au Gratin" sounds more elegant than the German "Überbackener Fisch mit Kase", so that's the way it's known, even in Germany.

It's "überbacken" meaning, "baked over" so the cheese melts and browns.
