Peel the asparagus (cut only the ends of green asparagus) and cut into 5 cm long pieces. Cook in water with sugar and a little salt for about 10-15 minutes until al dente.
In the meantime, cut the two types of ham into fine strips and fry in the pan with half of the butter. Then drain and drain the asparagus. Grease a baking dish with the remaining butter and add the asparagus pieces, mix in the ham. Now mix the eggs with the cream, nutmeg, pepper and a little salt (add the chives if you like) and pour over the asparagus. Bake the casserole in the oven at 200 ° C for about 15 minutes. Scatter the cheese on top 5 minutes before the end of the baking time.
We eat the casserole as a main course with a baguette and a fresh leaf salad.
