Mix the quark and eggs, add the buttermilk and flour and stir to a smooth batter. Season well with salt, pepper and grated nutmeg.
Let the dough rest for about 20 minutes.
In the meantime, bring a large saucepan of salted water to a boil.
Press the dough through a spaetzle press (or with a spaetzle board) into the boiling water. When the spaetzle float on the surface, skim it off with a skimmer and place in an ovenproof dish. Sprinkle with parsley and cheese and bake in the 250 ° C oven for 5-6 minutes.
The spaetzle also taste good if you just toss them in a pan with butter.
