Ingredient Notes
Using starchy potatoes will give you that classic crispy texture in the rösti. You can substitute olive oil with any neutral oil if desired. Fresh dill works best in the sauce, but dried dill can be used in a pinch.
Kitchen Tools Needed
- Coarse grater
- Colander
- Large frying pan
- Spatula
- Small saucepan
- Blender (for the sauce)
Step-by-Step Instructions
- Begin by grating the 800 g (about 1.75 lbs) of potatoes using a coarse grater. This creates that ideal texture for crispy rösti.
- Rinse the grated potatoes under cold water to remove excess starch, then drain in a colander. Squeeze lightly to eliminate any extra moisture.
- In a large frying pan, heat a generous amount of olive oil over medium heat. Add one chopped onion and sauté until translucent, about 3-5 minutes.
- Add the drained grated potatoes to the pan and fry for 5–7 minutes, stirring occasionally, until they start to become crispy.
- Season with salt, black pepper, and paprika to taste. Ensure you mix everything evenly.
- Stir in 4 tbsp of starch, which helps bind the mixture. Scoop the mixture and shape it into long flatbreads.
- Continue frying the shaped rösti in olive oil until both sides are golden brown and crispy, around 4-5 minutes per side.
- While the rösti is cooking, heat another pan. Add a little olive oil and sauté the second chopped onion, 100 g sliced mushrooms, and 2 cloves of minced garlic until fragrant, about 5 minutes. Add coriander, salt, and pepper to taste.
- Pour in 100 ml of cream and simmer until it thickens slightly, about 3-4 minutes. Remove from heat and let it cool for a moment.
- Carefully blend the mixture until smooth, then stir in the chopped dill.
- Serve the creamy mushroom dill sauce alongside the hot, crispy rösti.
Pro Tips
- Ensuring your potato mixture is dry will help achieve that perfect crispiness. Squeeze out as much water as possible.
- Preheat your pan properly so the rösti gets that nice browned texture without cooking too slowly.
- If possible, let the rösti rest on a paper towel briefly after frying to absorb excess oil.
Common Mistakes
- Using waxy potatoes can lead to soggy rösti; always opt for starchy varieties.
- Not squeezing the grated potatoes can trap moisture, preventing crispiness.
- Overcrowding the pan will steam the potatoes instead of frying them; fry in batches if necessary.
Variations
- Add grated cheese to the rösti mixture for a cheesy twist.
- Use different herbs in the sauce, like chives or parsley, for a unique flavor.
- Opt for different mushrooms, such as shiitake or portobello, to change the sauce’s flavor profile.
- Mix in some cooked bacon or ham into the mushroom sauce for extra richness.
Serving Suggestions
Serve your crispy rösti with a generous dollop of the creamy mushroom dill sauce on top. It pairs wonderfully with a fresh salad or an egg cooked to your liking for breakfast.
Storage Instructions
Store any leftovers in an airtight container in the refrigerator for up to 3 days. The rösti can become a bit soft, so it’s best to only keep the sauce separate.
Reheating Tips
For the best texture, reheat the rösti in a hot skillet for a few minutes to restore crispiness. The sauce can be warmed gently on the stove.
