If you like your Potato Rosti crispy instead of soggy, and deep golden instead instead of burnt, don’t skimp on the fat. If you want ultimate flavour, use clarified butter like the Swiss do instead of butter or oil – it’s super easy to make your own.
And if you want ultra ultra crispy, make small thin ones instead – they are literally potato crisp crispy!
She who was labelled Potato Girl by her family when she was a mere teenager cannot comprehend how she’s made it through 6 years with a recipe website and not shared a rosti recipe.
At least, not “properly”. A variation of it is buried in this old Smoked Salmon Rosti Stack breakfast recipe.
But – onwards! It has arrived, ready to serve alongside your schnitzels, parmies, an epic standing rib roast or roast chicken!
Difference between rosti, hashbrowns and latkes
Broadly speaking, they are similar as they are all made with shredded potatoes that are pan fried until crispy. The other thing they all have in common is that I am a fan of all three.
However, there are subtle differences:
- typically, rostis – which originate from Switzerland – are pan fried in a medium(ish) skillet then cut up to serve as a side dish for a meal;
- hash browns are usually individual size – think, Maccers hash browns – and served for breakfast; and
- latkes are also individual size but typically bound with some egg and flour, and because of these additions, they are not as crispy – unless you use basically deep fry them.
What you need for potato rosti
Here’s all you need to make Potato rosti (I get salt and pepper for free!):
- Potatoes – there’s no definitive rule about what type of potatoes to use, and there’s no need to get pedantic about it either! Floury potatoes will make the inside more fluffy, a bit like mashed potato, and waxy potatoes hold those lovely strands better, but still very soft and cooked through. Both go nice and crispy, albeit waxy potatoes get a bit crispier. In all honesty, use whoever you prefer – I just use all rounders all floury potatoes to get the best of both worlds. I use Sebago potatoes (Australia, the dirt brushed type) which is a great all rounder that leans towards floury. The equivalent in the US are Russets though Yukon Golds are excellent all rounders, and in the UK – Maris Pipers, King Edward and Desirée;
- Clarified butter or ghee (same thing) – for flavour and crispiness. This is simply pure butter fat and can be purchased from most grocery stores nowadays, usually in the Indian section labelled as “ghee”.
Basically, butter is made up of fat, water and dairy, and the water and dairy components are removed so it’s pure butter fat which has a higher smoke point (ever set off your smoke alarm with burning butter??) and you don’t get little black bits when you pan fry for more than a few minutes (the burnt dairy).
It makes the rosti crispier than using just butter (because of the water in the butter) and also has a more intense butter flavour. It’s sold in grocery stores in the Indian section labelled Ghee, usually with a helpful “Clarified Butter” label underneath. But it’s a cinch to make your own – How to make Clarified Butter / Ghee.
Best alternative: butter and oil combo. Just using butter gives a better flavour but won’t make it as crispy and you get little black bits from the burnt bits of butter. Just using oil doesn’t have as nice a flavour.
How to make Potato Rosti
If you’re staring at the giant rosti and already fretting about The Flip – don’t! My trick is to use a wooden board with a handle or even a cutting board – just something with overhang that you can grip onto for the flip. Much easier than using a plate (says the girl who has lost more rosti than she cares to remember by attempting a plate flip ).
- Grate the potatoes using a standard box grater. I like to do it lengthwise to get nice long strands – but it really doesn’t matter how long or short your strands are;
- Squeeze out the excess liquid then transfer to a bowl. Don’t worry if you’re potatoes go brown / reddish – this is just from oxidisation (exposure of potatoes to air) and it’s all bluster, it doesn’t mean the potato is off. Once you start cooking, it will change back to white;
- Mix the potatoes with melted butter (or clarified butter, if that’s what you’re using), salt and pepper;
- Scatter into skillet lightly, don’t pack it down tightly. We want FLUFFY on the inside! Then cook for 12 minutes on medium low. It takes longer than you think to become golden because residual water from the potato leeches out and that needs to evaporate – it sort of “steam” cooks the inside – before the underside goes golden and crispy;
- Flip! When the underside is golden (use a rubber spatula to peek), using a round wooden board with a handle or even a large rectangle cutting board (or plate, if you are a pro!) to cover the skillet then quickly turn to flip! Using a plate is a little more difficult because you don’t have anything to hold onto so you need to press the plate and skillet together very firmly and hold them together as you flip. It’s much easier to do that manouevre with something with a handle. Once I switched from a plate to a wooden board with a handle, I’ve never lost part of a rosti during The Flip! It’s also easier to slip the rosti back into the skillet if you use a board, rather than a plate with a ridge;
- Lift the skillet off to reveal the golden underside. If at this stage, you realise it’s not as golden as you thought, just flip it back into the skillet and keep cooking;
- Slide the rosti back in, raw side down and cook for a further 12 minutes or until you can slide a knife through the centre easily, with no resistance from uncooked potato; and
- Slide the rosti onto a serving platter or cutting board. Cut into (large!) wedges and serve immediately!
How to make rosti super crispy
The crispiness of a rosti comes down to the amount of fat you use to cook it – and nothing more. Any type of potato cooked in plenty of fat will become very crispy – waxy or floury.
I use 4 tablespoons / 60g of clarified butter to cook my rosti and it makes it quite crispy on each side, but still fluffy on the inside. You will hear how crispy it is in the recipe video!!
However if you make thin small ones, they can be potato-crisp type crispy. As in, THIS crispy:
They are pretty much like potato crisps when they’re this thin!
So for those of you who rate crispiness very highly, this might beg the question – why would you make a large one instead of small ones?
For small rostis, it takes up to 10 minutes per batch – 3 to 4 in a medium/large skillet. They will stay warm and crisp in the oven, but if you’re feeding a family of 4, that’s a LOT of batches you need to make, and the time quickly adds up.
On the other hand, one giant rosti takes 25 minutes to cook, and it’s low maintenance at that. So for me, it’s a no brainer – I always go the giant form.
What to serve with rosti
The first thought for most people is Schnitzel – it’s a pub grub favourite here in Australia!
But actually, I find rosti to be a really handy starch side dish that’s cooked entirely on the stove when a centrepiece requiring exact cook times is hogging the oven. When I’ve invested in a precious prime rib, or I’ve been slaving for hours over the perfect Roast Turkey, or making the best ever Roast Chicken, I do not want to muck up oven temps by cramming the oven full of other stuff. Stay away from the oven, people!
So a grand potato side dish that’s made on the stove is a very handy recipe indeed. Plus, it’s a show stopper. I mean, who doesn’t go ga ga over potatoes in giant golden form like this? – Potato Girl x
Watch how to make it
Crispy Potato Rosti
- 1kg/ 2 lb potatoes (skin on weight) - Aus: Sebago (dirt brushed), US: Yukon Gold, Russet, UK: Maris Piper, King Edwards (Note 1)
- 3/4 tsp salt , kosher/cooking salt (or 1/2 tsp table salt)
- 1/2 tsp finely ground black pepper
- 15g/ 1 tbsp clarified butter / ghee or normal butter , melted (Note 2)
- 60g/ 4 tbsp clarified butter / ghee , separated (30g/2 tbsp for each side) (Note 2)
Grate & squeeze:
- Peel then grate the potatoes using a box grater, trying to get nice long strands if you can.
- Grab handfuls of potato and squeeze out excess liquid, then place in bowl. This helps make the potato crispier (otherwise all that water has to steam out in the pan).
- Add butter, salt and pepper then toss. Don't worry if your potatoes go brown/reddy - it's still safe to eat, and turns white again when cooked.
- Melt half the clarified butter in a 26cm / 10.5" non stick skillet (or thereabouts) over medium low heat. Shallow non stick pan with sloped sides best (for easy removal).
- Place the potato in - do not pack down. Use rubber spatula to tidy the edges, then lightly pat down to even surface.
- Cook Side 1: Cook 12 minutes until underside is very golden and crispy, lift edge with rubber spatula to check. If by 8 minutes it is not going golden, increase heat.
- Insurance policy: If you didn't use a non stick pan, slide the rubber spatular underneath all the way to the middle and run it around, to be 100% sure nothing is stuck.
- Flip: Cover pan with a round wooden board with a handle (or anything similar with a handle, Note 3). Holding the handle of the board, flip quickly - and with confidence!
- Cook Side 2: Melt remaining clarified butter in the pan, then slide the rosti back in and cook for 12 minutes until golden crispy, and there is no resistance when a knife is inserted into the middle.
- Slide onto cutting board, cut into 4 or 6 wedges and serve immediately!
- Use 25g / 1 1/2 tbsp clarified butter for each batch, medium heat in a non stick pan. Place potato in rounds in a skillet, around 8cm / 3" wide, 1.5 - 2cm / 2/3" thick (without patting down). Cook 5 minutes until deep golden and crispy, flip, repeat.
- Transfer to rack set over tray, keep warm in 120°C/250°F oven.
- Normal melted butter for mix into potato (just a touch helps disperse salt and pepper better, plus touch of extra flavour).
- Cooking: 15g / 1 tbsp butter + 1 tbsp vegetable oil for each side you cook.
