Rösti Like Grandmother's — Crisp and Golden
Yvonne Ammann VegetarianThe best rösti starts with Gschwellti — potatoes boiled the day before and left to cool. Grate them coarsely, fry in plenty of butter over medium heat for 15 minutes a side, and move them as little as possible. That is the whole secret.
Rösti is Switzerland's national dish, and also the one that goes wrong most often. Nearly always the cause is freshly boiled potatoes: too moist, they stick together and turn stodgy instead of crisp. The trick is unglamorous — boil the potatoes a day ahead. Everything else is butter and patience.
Ingredients
- 1 kg Potatoes (waxy, boiled the day before)
- 3 tbsp Butter
- 1 tbsp Clarified butter
- 1 tsp Salt
- Pepper (optional)
Variations
- 100 g Diced bacon (optional)
- 100 g Cheese (grated, e.g. Gruyère) (optional)
Method
- 1
Boil the day before
Boil the potatoes in their skins in salted water for 20 minutes, until only just tender. Drain, let them cool and refrigerate overnight.
- 2
Grate
Peel the cold potatoes and grate them on a rösti grater or the coarse side of a box grater. Tip loosely into a bowl and salt — do not press or knead.

Into the pan
Heat the clarified butter and half the butter in a 24 cm non-stick pan. Add the grated potatoes, spread them loosely and press down only lightly.

Fry the first side
Fry over medium heat for 15 minutes without stirring. It should sizzle quietly, not spit. When the edge turns golden and comes away, it is ready.
- 5
Turn
Place a plate over the pan, invert it, and slide the rösti back in. Add the remaining butter around the edge.

Fry the second side
Fry for another 12 to 15 minutes, until this side is golden too. Turn out onto a plate and serve at once — rösti does not wait.
Tips
- Freshly boiled potatoes are the most common reason rösti fails. They hold too much moisture — a night in the fridge firms the starch so the shreds stay separate.
- Do not skimp on the butter. Rösti is a butter dish; too little fat makes it dry rather than crisp.
- The less you stir, the better. Every turn destroys the crust that is just forming.
What can I substitute?
Clarified butter burns less easily and is the traditional choice. Plain butter tastes better but needs slightly lower heat.
Raw rösti is its own equally common variation. Squeeze the shreds dry and allow 5 minutes more frying time.
Onion rösti is the classic vegetarian variation. Fry the onion briefly before the potatoes go in.

Frequently asked questions
Why does my rösti fall apart?
Usually the starch that binds the shreds is missing. Use potatoes boiled the day before, press the mixture lightly in the pan, and genuinely leave it alone for the first 15 minutes. Turning too early is the second most common cause.
Which potatoes are best for rösti?
Waxy varieties such as Charlotte, Nicola or Ditta. They keep their structure when grated. Floury potatoes collapse into mash and are better suited to purée or gnocchi.
Can I make rösti without pre-boiling?
Yes — that is raw rösti. Grate raw potatoes, wring the shreds out firmly in a cloth and fry about 5 minutes longer. It comes out crisper but less creamy inside than the boiled version.
What is served with rösti?
Classically with Zürcher Geschnetzeltes, but also as a main course with a fried egg and bacon (Bauernrösti), baked with cheese, or simply with apple sauce. In western Switzerland it often accompanies sausage.
Can I freeze rösti?
Yes. Let the finished rösti cool, freeze it in portions and crisp it up straight from frozen in a pan or in the oven at 200 °C. It comes back almost as crisp as fresh.
