Rösti originally comes from Switzerland, however, it is rösti. Regardless of how you spell it, the potato dish is a well-known and beloved side dish for many types of meat and vegetarian dishes.
Potatoes and onions are coarsely grated on a grater.
The grated potatoes and onions are pressed/squeezed free of moisture in a dishtowel. Change the cloth if it becomes too wet - it is essential to press as much moisture out of the potatoes as possible. This way, the potatoes become deliciously crispy instead of soft.
Mix potatoes, onions, eggs, salt, and pepper well in a bowl.
Form the mixture into small, flat patties. Use a mold if you want completely uniform and perfectly shaped rösti. I did so in this case.
Heat a pan with plenty of butter and olive oil and fry your rösti over medium heat for 20-25 minutes on each side. They are then ready to serve.
