Prepare 3-4 bags of finely grated 11er Rösti Potatoes in an oven or a pan.

Layer the baked 11er Rösti Potatoes in a casserole together with an original Vorarlberg cheese spätzle mixture.

Finish off with a layer of deep-frozen 11er Rösti Potatoes.

Bake the casserole for 10-15 minutes in a 180°C oven.

To serve, sprinkle fried onions on top and decorate with chopped parsley and black pepper.
