Directions

1. Preheat oven to 230ºC / 450ºF.
2. In a skillet, sauté the onion in half of the oil and butter until caramelized. Set aside on the counter.
3. Stretch the dough out to form a 30 cm (12 in) circle.
4. Sprinkle some corn meal on a baking sheet and place the dough on top.
5. Using a mandoline, slice the potatoes and arrange the slices over the pizza, leaving a 2.5 cm (1 in) edge all around. Drizzle with oil and add the caramelized onions, rosemary, pepper flakes and cheeses. Season to taste with salt and pepper.
6. Bake about 15 minutes, until the cheeses are melted and golden and the crust is nicely browned.
7. Cut into wedges and serve.
