Season the schnitzel with salt, pepper and paprika powder and place in an ovenproof dish. Cut the mushrooms into slices and pour over the schnitzel.
Mix the cremefine, cream cheese, Parmesan and chives, season and pour over the schnitzel.
Bake in the preheated oven (200 ° degrees) on the middle rack for about 30 minutes. Scatter the rest of the parmesan on top 10 minutes before the end of the baking time - gives a nice cheese crust.
