Rosti Fantastico

Potato-based cakes and I have a bit of a chequered history. No matter how much advice kindly bestowed upon me by The Daily Spud, my potato cakes never quite stick together.

So it was with some trepidation that I approached this recipe for a Potato Rosti Cake. I erred on the side of caution throughout the whole cooking process and, happily, it was a rosti-good success!

We had this as part of Sunday brunch, with a simple poached egg and some Scullery tomato relish on the side. It would be great with some herby fried wild mushrooms or with some smoked salmon and creamy cheese. Do you think it would work as a side for a lovely curry?

As Catherine would say, rostinomz!

I think where I’ve failed before in making potato cakes is not using the right type of potatoes. Maris Piper potatoes are suggested for these rosti cakes, as they’re not too waxy and not too floury. So if you look for a similar potato-style (somewhere between floury and waxy), that will be the first step in the right direction.

The other thing you need to do, especially when grating potatoes for a cake, is to get the excess moisture away from the potatoes. This is achieved by squeezing the bejeesus out of the potatoes, either just over the sink using your hands or with kitchen towel.

The last thing I did to ensure this beauty of an over-sized potato cake didn’t fall apart was I let it cool in the springform tin before removing it. This means that you don’t have a piping hot rosti on your plate but it did make sure it kept its shape.

But, as my friend Lucy T suggested over on Instagram, if it falls apart, just fry it for a bit more in a frying pan and top it with an egg and call it a hash :)

I added some leeks to the original recipe. In future, I will do the same but I will set aside some grated potato to put on the top of the rosti, as the leeks burnt very easily on top.

What you need for a Giant Potato Rosti Cake (adapted slightly from Emma Lewis)

Olive Oil

1kg of Maris Piper potatoes

1 leek

100g of streaky bacon or pancetta lardons 

1 small white onion




Pre-heat your oven to 190C/170C fan/Gas Mark 5.

Peel the potatoes. Cook them in a saucepan of boiling water over a high heat for 5 minutes.

Heat a drizzle of olive oil in a frying pan over a medium to high heat. Finely chop your leek and wash it really well. Now fry the leek and bacon in the hot frying pan for 5 minutes, stirring from time to time so nothing burns.

After they’ve had 5 minutes, remove the potatoes from the heat and put them in a bowl of really cold water.

When cold enough to handle, coarsely grate each potato into a bowl.

Drizzle the grated potatoes with some olive oil as you go along so it doesn’t turn into one massive clump. Once the lot have been grated, squeeze the moisture out of the potatoes, a handful of grated potatoes at a time. Set aside one handful of grated potato to make the top of the rosti.

Peel and coarsley grate the small onion, squeezing out any moisture from it as well.

There’ll be a good bit of moisture in the onions. Now put into a large bowl along with the cooked leek and bacon and the grated potatoes (except the handful you set aside!). Season well with salt and pepper.

Put a baking sheet in the hot oven for 5 minutes to warm up. Now grease a 23cm loose-bottomed cake tin with a lotta butter.

Now you can put the potato mixture into the cake form tin, but don’t press it down. Just loosely put it into the tin. Remember that handful of grated potato you set aside? Use that at the very top layer of the rosti. Finally, dot the top of the rosti with butter.

Put on the hot baking sheet and bake in the oven for 1 hour and 20 minutes, until the potatoes are cooked through and crispy on top.

Now allow the rosti cake to cool until it’s warm rather than hot. Carefully remove it from the cake tin (FYI cake tins with spring clips on them are brillo) and transfer to plate.

Top with a poached egg and serve with a side of tomato relish. Lush!

  1. YEAH – fantastico!! Thanks for sharing our tune. I’ve never baked a rosti before – only frying pan technique, which generally makes me nervous that it won’t cook right through

    • You’re welcome! Thanks for helping me name this blog post :)

      Definitely give the baking a go – it cooked through and it stayed together well once I let it cool a bit in the tin. Win!
