Grate the Parmesan cheese if not already done and set aside.
Remove chicken from oven (15 mins later) and transfer chicken pieces to a plate and leave aside.
To the same pot with chicken juices left, add the cream fraiche, the paprika and the mustard.
Keep a little grated cheese for later and add the rest of the grated cheese to the sauce as you mix it with a wooden spoon.
