Peel the potatoes and grate with a grater. Season with salt, pepper and a little nutmeg in a bowl. Now mix the mass through. Pluck the fresh parsley from the stem, chop it into small pieces and mix it with the potato mixture.
Heat a large pan with oil or clarified butter, if you like. Only when the fat is very hot add half a handful of potato mixture to the hot fat and use a spoon to spread the potato mountain flat so that the rösti is approx. 2 cm high.
Fry the hash browns on full heat for about 2 minutes. When the sides are tan, the rösti is ready to be turned.
After frying, place the hash browns on a paper towel to soak up the excess fat.
