Boil the pasta in salted water, drain and rinse with cold water. Cut the raw ham into small cubes.
Layer the pasta, ham and cheese alternately in a greased baking dish sprinkled with breadcrumbs. Whisk the eggs with the cream, a little salt and nutmeg.
Pour this mixture over the casserole and sprinkle with butter flakes and breadcrumbs.
Put the dish into the preheated oven and bake at 200 °C for about 20-30 minutes.
