Crispy Swiss rösti made in the air fryer — golden and crisp on the outside with a soft inside. The perfect side dish with just a few ingredients and minimal effort.
Peel 800 g waxy potatoes and grate them coarsely on a grater. Place the grated potatoes in a bowl of cold water for 5 minutes to draw out some of the starch.
Tip the potatoes onto a clean tea towel and squeeze out as much water as you possibly can. This step is crucial for a crispy result.
Put the squeezed potatoes in a dry bowl and mix with 1 tsp salt, 0.5 tsp freshly ground pepper, 2 tbsp butter and 1 tbsp olive oil, so all the grated strands are evenly coated.
Cooking in the air fryer
Preheat the air fryer to 200 °C fan.
Place a piece of parchment paper in the air fryer basket. Spread the potato mixture out evenly in a layer about 2 cm thick, and lightly press the surface together with a spatula.
Cook at 200 °C for 18-20 minutes. Carefully turn the rösti with two spatulas, or by sliding it onto a plate and tipping it back, halfway through cooking, so both sides turn golden.
Let the rösti rest 2-3 minutes outside the air fryer, so the surface sets and becomes extra crispy. Cut into wedges and serve immediately.
Notes
Tips for the perfect result:
The most important thing for a crispy rösti is to press all the water out of the potatoes — the drier, the crispier. Wring the tea towel tightly until no more liquid comes out. Use waxy potatoes (such as Asparges or Folva), as floury varieties fall apart.Variation:
Grate in a small onion or sprinkle grated gruyère over the last 5 minutes of cooking for a richer Swiss version. Herbs such as thyme or rosemary also work well.Serving:
A classic side for schnitzel, smoked salmon with crème fraîche or fried eggs and bacon for brunch. Also excellent alongside steaks.Extra crispiness:
Spray lightly with oil before cooking and keep the layers thin. If your air fryer is smaller, make the rösti in two smaller cakes instead of one large one.
