If you have ever wondered why your rosti did not crisp up properly, this version fixes that. It is all about squeezing the potatoes and cooking in the right fat.
Ingredients
- 1 kg (2 lb) potatoes, skin on weight (Yukon Gold, Russet, or other all-purpose potatoes)
- ¾ teaspoon kosher salt (or ½ teaspoon table salt)
- ½ teaspoon finely ground black pepper
- 1 tablespoon clarified butter or ghee, melted
Ingredient Notes & Substitutions
Potatoes:
You can use either waxy or starchy potatoes. Waxy potatoes hold their shape and give you beautiful defined strands. Starchy potatoes turn slightly fluffier inside, almost like mashed potato tucked under a crust. I often use Yukon Gold because they strike a lovely balance.
Clarified butter or ghee:
This is the key to truly crispy potato rosti. Clarified butter has the milk solids removed, so it has a higher smoke point and gives you that deep golden crust without burning. If you are curious about how it differs from regular butter, this guide from Serious Eats explains it clearly and simply.
If needed, you can cook with half butter and half vegetable oil, but clarified butter gives the best texture and flavor.
Instructions
- Peel and grate the potatoes.
Use a box grater and try to get long strands. Long strands create that signature rosti texture. - Squeeze out excess moisture.
Grab handfuls of grated potato and squeeze firmly over the sink. This step is so important. Removing the water helps the rosti crisp instead of steam. - Season the mixture.
Place the squeezed potatoes in a bowl. Add melted clarified butter, salt, and pepper. Toss gently to coat. If the potatoes turn slightly brown, that is completely fine. They will turn golden as they cook.
- Heat the pan.
Melt half of the clarified butter in a 10 to 11 inch non-stick skillet over medium-low heat. - Shape the rosti.
Add the potatoes without packing them too tightly. Lightly pat the top to even the surface, and tidy the edges with a spatula. - Cook the first side.
Let it cook for about 12 minutes. Gently lift an edge to check. You want a deep golden crust. If it is pale after 8 minutes, raise the heat slightly.
- Flip with confidence.
Place a round wooden board or large plate over the pan. Hold it firmly and flip in one smooth motion. It sounds dramatic, but it is easier than you think. I promise. - Cook the second side.
Melt the remaining clarified butter in the pan, then slide the rosti back in. Cook another 12 minutes until golden and crisp. A knife should slide easily into the center with no resistance. - Serve immediately.
Slide onto a cutting board and slice into wedges. That first crunchy cut is always my favorite moment.
Pro Tips for Success
- Do not skip squeezing the potatoes. Extra moisture is the enemy of crispiness.
- Use medium-low heat so the inside cooks through before the outside browns too quickly.
- A non-stick skillet makes flipping much easier.
- For ultra crispy results, make smaller 8 cm rounds about 1.5 to 2 cm thick. They crisp up beautifully.
Storage and Reheating
Store leftover rosti in an airtight container in the refrigerator for up to 3 days.
To reheat, place on a rack over a tray in a 390°F (200°C) oven. Heat about 7 minutes for small rostis and 10 minutes for a large one. They regain that lovely crisp edge.
Make Ahead & Freezing
You can grate and squeeze the potatoes a few hours ahead. Keep them covered in the fridge until ready to cook.
Cooked rosti can be frozen once cooled. Wrap tightly and freeze up to 3 months. Reheat straight from frozen in a hot oven until heated through and crisp again.
Tips and Variations
- Healthy variation: Use slightly less clarified butter and cook smaller rounds for lighter portions.
- Quick brunch idea: Top with a fried egg and a spoonful of sour cream.
- Flavor twist: Add finely chopped chives or a pinch of smoked paprika to the potato mixture.
- Cheesy version: Sprinkle a little grated Gruyere into the center layer for a melty surprise.
- Dinner side: Serve alongside my Easy Roast Turkey for a cozy holiday table.
FAQs
Removing moisture and cooking in clarified butter are the two biggest factors. A properly heated pan also helps create that golden crust.
Yes, but combine butter with a little oil to prevent burning. The texture may be slightly less crisp.
Usually it means the potatoes were not squeezed enough or the heat was too high, causing the outside to brown before the inside cooked through.

Notes
For ultra crispy results, make smaller thinner rostis and cook about 5 minutes per side. To keep warm, place on a rack over a tray in a 120°C/250°F oven. Small rostis reheat best in a 200°C/390°F oven for 7 minutes.
Serving Suggestions
Crispy Potato Rosti is wonderful for brunch with eggs and fresh herbs. It is also perfect as an easy dinner side with roast chicken, steak, or even a simple green salad.
For a cozy fall meal, try serving it with my Cheesy Root Vegetable Gratin or Ultimate Green Bean Casserole. The contrast of creamy and crispy is so satisfying.
Sometimes I serve it simply with a dollop of sour cream and cracked black pepper. That is all it needs.
