Fry the cleaned, finely chopped mushrooms in oil. Pour in 400 ml of water and 100 ml of cream, stir in the soup and briefly bring to the boil. Now put the uncooked pasta in a flat baking dish and pour the sauce over it. The noodles should be completely covered in sauce. Sprinkle the whole thing with cheese and bake in the preheated oven at 200C for about 25 minutes
