This recipe for Rösti yields the most perfect crispy potato crust. Here I dress it up with creme fraiche and caviar but you could easily just serve it with a fried egg for breakfast.
What is rösti?
A rösti has been on my to-make list for a v v long time. If you’re unfamiliar, think of it like a latke but bigger and thicker. It’s more cake-like. I thought about making this rosti out of other things besides potatoes, but the thing I enjoy about them the most is their crispiness. And nothing in the entire world can get crisper than a potato. It’s made for dat crisp. Plus, the origin of the dish is Swiss where it was usually eaten with sausage as a breakfast dish. Potatoes and sausage is just classic breakfast combo.
What is the difference between a rösti and a latke?
If you’re asking yourself, “what is the difference between a rösti and a latke?!” not to worry, here’s the answer: A latke is held together with a bit of flour and egg, while a rösti is only held together with melted butter. It makes the execution a bit tricker.
Latkes are also much thinner than röstis which tend to be thicker and taller. Since there is no binder, the technique is pretty imperative. I used the technique from Chef Steps because they do a lot of good work over there and it was super duper simple.
How to make potato rösti crispy:
Most important is that you want thin strips of potatoes and you want to dry them really well. You basically mandoline potato slices and cut those slices into strips. You’ll end up with long potato strips that are dried and then tossed with butter and a bit of salt. Those are packed into a pan, cooked on both sides and that’s about it. It couldn’t be simpler.
How to make potato rösti in the oven:
You always want to start the rösti on the stovetop then finish them in the oven. That way you get the initial crisp and then use the oven to help cook them through. The trick is to make sure you’ve got a pan that can be used on both the stovetop and inside the oven.
I made two röstis in mini cast iron pans but feel free to double the recipe to fill one cast iron or, honestly, use whatever pan you have. This is one of those recipes that is super flexible.
Tips and Tricks:
If you want to make these ahead of time, just prepare the potatoes up until the soaking point and leave them refrigerated in the water but only for a couple hours max. Too long and they’ll soak too much water and possibly discolor.
Classic Rösti
Ingredients
- 2 russet potatoes peeled
- 1/2 cup unsalted butter melted
- 1 teaspoon salt
- 1 tablespoon creme fraiche for topping
- 1 dollop of caviar for topping
Instructions
- Preheat oven to 375 degrees F. Grease with cooking spray (or rub with oil) either 2 (5-inch) mini cast iron pans or a 1 (10-inch) cast iron (or really any other non-stick pan you have that's comparable in size),
- Fill a medium bowl with water. Mandoline each potato into 1/16-inch slices. Stack about 3 to 4 slices and cut into matchsticks. The matchsticks should be thin enough so that they are bendable. Transfer the matchsticks into the bowl with water so they can soak and some of the starch can be released. Repeat with the remaining potato slices.
- Drain the water and transfer the potatoes to a bed of paper towels and gently pat them down until they're dry. Place the potato matchsticks in a clean medium bowl and toss with the melted butter. Sprinkle with salt and toss once more.
- Place the pan(s) over medium-high heat. If you're using two pans, divide the potatoes amongst the pans and press them down into the pan, creating one even layer that's about 2 to 3 inches thick. Allow to cook for about 5 to 6 minutes, until golden brown and crispy. Transfer to the oven (without flipping it) for about 15 minutes. Remove from the oven and carefully flip it over to it's other side; transfer to the oven to bake for an additional 15 minutes. Remove from the pan and sprinkle with a bit of salt. Top with a dollop of creme fraiche and some caviar.

Hi! How do you get a 2-3″ depth in a 10″ pan with only 2 potatoes…? Do you have a suggested total weight instead of qty.? I want that nice traditionally thick, grated potato rosti. Thanks!
My potatoes totaled 3 pounds. That should do the trick! (If you’re worried, I would buy an extra potato!)
That makes a big difference, especially since they settle while cooking. Thanks!
Golly- on this gray, rainy and raw Midwestern day, nothing sounds better than this. Thank you for this recipe. I seriously want to sit in a corner and eat these all day…
Haha ME TOO!
This sounds amazing! I’ve made latkes many times because my sisters are from Ukraine and they grew up eating them so I know they’d love these just as much!
I love latkes!
Rösti is one of the most traditional dishes in Switzerland and it is almost a “religion” if you make your Rösti with raw or pre-boiled potato (if you do use pre-cooked they have to be from the day before). I do not want to “argue” about this fact :o)
An easier and faster way to prep your spuds for Rösti (and the way we do in Switzerland) is to you use your (box) grater and you grate them with the coarse side.
Ahh yes, I’ve read a lot about grating but I kind of favored the longer strands of potatoes. 🙂
Thank you very much! Your blog is always full of great idea. They are really helpful
Thanks!
