Mix the milk, mustard, garlic and the spices in a bowl and add the chicken schnitzel. Cover and marinate in the refrigerator for at least 1 hour (preferably overnight).
Mix the cheese, flour and herbs well and place in a deep plate. Turn the marinated schnitzel in it and place on a baking sheet lined with baking paper. Bake in a preheated oven at 180 ° C for approx. 35 - 45 minutes (depending on the thickness of the meat).
