I ate a potato pizza at The Actress recently. This started a carb binge which shows no signs of letting up. The idea of potato on pizza may seem strange, but it’s a classic Italian topping. No tomato sauce and usually, no cheese. I had to have another. Wafery potato slices received a damn good rubbing with crushed garlic, thyme (in the absence of rosemary) and olive oil. I let them sit while I properly caramelised some red onions; long and slow.
I smeared a thick layer of the gooey onions onto an oil-brushed base, followed by the potato slices, overlapping to form a semi-translucent pattern. Very pretty.
The potatoes caramelise in the oven to a highly savoury crust, enhanced with a final sprinkling of rocky salt. The slices crisp and curl at the edges while the overlapping bits maintain some bite.
The best pizzas are topped simply and this is a good example. That said, a little cheese most definitely wouldn’t hurt. I rather like the idea of Josh’s Gorgonzola version.
I used this dough recipe as I’ve not come up with a favourite of my own yet. It was fine, not the best I’ve tried but very easy and the results were more than passable. I used half the quantity which made 2 pizzas.
For the topping
3 large potatoes
2 cloves garlic, crushed
2 large sprigs of thyme (leaves stripped). I prefer rosemary to be honest – use about a tablespoon of roughly chopped leaves.
5 very large onions, sliced
Begin by caramelising the onions. Heat a couple of tablespoons of oil in a heavy-based, lidded pan then when hot, add the onions, turn down the heat to the lowest setting, put the lid on and allow to cook gently, stirring every now and then. It will take about an hour for them to become very soft and caramelised.
For the potatoes, either slice them very thinly using a mandoline or use a knife, as I did. You want them as thin as possible otherwise they won’t cook properly in the oven. Mix them really well with the crushed garlic, herbs and a tablespoon of olive oil, season with salt and pepper and leave until your onions are ready.
Preheat the oven to its highest setting. Preheat a pizza stone too if you have one. You can also use an upside down baking tray, but don’t preheat it.
When ready to assemble the pizza, brush the base with olive oil, then spread a thick layer of the onions on top. Add the potato slices so that they’re slightly overlapping and there are no gaps. Add a little extra sea salt on top of the pizza.
Cook the pizza for about 10 minutes, or until golden brown. It’s rather nice with a sharp green salad.
