Bread the schnitzel: first turn in flour, then pull through the beaten eggs, finally turn in breadcrumbs.
Fry them in a little hot clarified butter on both sides until golden, then place in a baking dish.
Dice the ham and distribute evenly over the schnitzel. Put a chopped onion on each schnitzel
Pour on the sweet cream, cover with aluminum foil and refrigerate for 24 hours.
Bake the next day in the oven at 175 ° for about 40-50 minutes. Leave the aluminum foil on the mold, maybe open it slightly in one place. The cream will not dry out and the schnitzel will stay juicy.
