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!

Potato Rosti

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:

  • Rostis (or properly spelt rösti), which originate from Switzerland, typically 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 Macca’s hash browns – and served for breakfast; and
  • Latkes are also individual size but usually 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!):

Ingredients in Potato Rosti

  • 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 whichever you prefer – I just use all-rounder 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. Make your own (it’s cinch!) or buy it (Indian section of large Australian grocery stores, labelled Ghee).

Ghee and clarified butter is simply pure butter fat. Butter is made up of ~84% fat, and the rest is water and dairy (milk solids). The water and milk solids are removed leaving pure butter fat which has a much higher smoke point (ever set off your smoke alarm with burning butter??🙋🏻‍♀️). You also won’t have the little dark brown/black flecks you get when cooking in butter for more than a few minutes, which are the burnt milk solids.

Clarified butter also makes the rosti crispier than using normal butter (because butter has some water content = bad for frying) and also has a more intense butter flavour.

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 Dreaded Flip – don’t! My trick is to use a wooden board with a handle or even a cutting board – just something with some protrusion 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 😩).

How to make Potato Rosti

1. Grate the raw 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. There is no need to parboil – I find that makes the inside too much like mashed potato before the outside gets golden;

2. Squeeze out the excess liquid then transfer to a bowl. No need to be 100% thorough here, squeezing out every drop of water, because we actually need some of that water to help steam-cook the inside (otherwise it takes forever to cook through!).  – we want to remove as much water as possible to promote crispiness. That’s why I just grab handfuls rather than using a tea towel which is more thorough.

However, squeezing out most of the water is necessary because otherwise all that water leeches down to the base of the pan as it cooks and it does eventually evaporate, but it takes longer and stops the base from getting really crispy.

Don’t worry if your potatoes go brown / reddish while sitting around. This is just from oxidation (reaction of potato 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;

3. Mix the potatoes with melted butter (or clarified butter, if that’s what you’re using), salt and pepper;

4. Scatter into skillet lightly, don’t pack it down tightly. We want FLUFFY on the inside! It will seem quite deep – around 3.5cm / 1.5″ – but it cooks down to 2cm / 4/5″.

Cook for 12 minutes on medium low to make the underside golden and for the inside to cook through and semi-adhere together. We don’t want mash – we just want the strands to cook through until soft and bond together enough to be sliceable without falling apart. This is the reason it’s best not to rinse the grated potato – because it removes much more starch than just squeezing out excess water. This results in “slippery” potato strands, rather than bonding together.

It takes longer than you think to become golden because residual water from the potato leeches out and that needs to evaporate – which also sort of “steam-cooks” the inside – before the underside goes golden and crispy.

Individual Rosti

If you’re making small ones, just place the potatoes into small rounds. Again, don’t pack them down – place the potato in the skillet, then use a rubber spatula to push the sides in to form rounds. Resist the temptation to use rings – those little pokey bits on the side get extra crispy!!

How to make Potato Rosti

5. 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 manoeuvre 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;

6. Lift the skillet off the board 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;

7. Slide the rosti back in, uncooked 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

8. 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-level 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?

Sheer practicality.

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 large format.

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, especially around the holiday season – Christmas, Thanksgiving, Easter.

Of course, rosti also makes a wonderful addition to the breakfast table, whether in lieu of hash browns alongside bacon and eggs, or accompanying grander affairs like last week’s Eggs Benedict. Though that’s one ambitious breakfast spread, even I’ll freely admit! – Potato Girl x

Crispy Potato Rosti

Recipe video above. If you want crispy and deep golden instead instead of burnt, don’t skimp on the fat. If you want ultimate flavour, use clarified butter or ghee instead of butter or oil – buy it, or make your own (it’s super easy).

And if you want ultra ultra crispy, make small thin ones instead – they are literally potato crisp crispy!

This recipe would probably serve 6 normal people, but in my family it serves 4. Makes 1 giant rosti about 2cm / 4/5″ thick, or 10 – 12 small rostis.

Ingredients

  • 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)

Cooking:

Instructions

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.

Cook

  • Melt half the clarified butter in a 26cm / 10.5″ (or thereabouts) non-stick pan or skillet over medium low heat. Shallow non-stick pan with sloped sides is best for easy rosti removal.
  • Place the potato in pan, but do not pack down. Use rubber spatula to tidy the edges, then lightly pat down to even surface.
  • Cook first side: Cook 12 minutes until underside is very golden and crispy, lifting edge with rubber spatula to check. If by 8 minutes it is not going golden, increase heat.
  • TIP: 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 before attempting flip.
  • 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 second side: 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!

Small rosti

  • 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, and cook another 5 minutes until done.

To hold / keep warm

  • Transfer to rack set over tray in a 120°C/250°F oven until ready to serve.

Notes

1. Potatoes – rosti works very well with either waxy or starchy potatoes. Floury potatoes go a bit more fluffy inside (like mashed potato) whereas waxy goes soft but still holds those lovely strands. Both go crispy – waxy is probably a touch crispier. There’s no definitive rule about what types of potatoes are best, so if you want to hedge your bets as I do, use a good all-rounder or leaning slightly towards floury (Aus all-rounder: Sebago – the common dirt brushed potatoes, US: Yukon Golds, UK: Maris Piper or King Edwards)

2. Clarified butter / ghee (same thing) – this is butter with water and milk solids removed so it has a more intense butter flavour, higher smoke point and will make things crispier. Sold in jars labelled “ghee” in the Indian section of large supermarkets (Coles/Woolies) and cheaper at Indian stores. Or make your own – it’s super easy and cheaper, lasts for months in the pantry and you will use it to pan fry and roast everything!

In Europe/UK, clarified butter in jars is also quite common.

SUBS:

  • 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.

3. Flipping vehicle – the ideal method is using a round wooden board with a handle. Hold the handle when you flip – you will have much more control than trying to flip with a plate where you can only keep your hand on the base of the plate. A wooden board with a handle will also work, but be sure to position the rosti closer to the handle so you have more control when you flip.

Alternatively, use a rectangle board or large flat plate and rope in a helper. With 4 hands, it’s much easier!

4. Reheating: Small rosti – on a rack over a tray in a 200°C/390°F oven, 7 minutes. Large rosti – same temp and rack method, about 10 minutes. Small rostis reheat with more crispiness.
