Instructions

1

Preheat the oven to 190°C and lightly grease a baking tray.

For the topping, heat the butter in a large frying pan over a low heat. Add the onions and stir until coated with the butter.

Add the sugar and stir until the onions are soft and golden brown, about 10 minutes.

Place the mozzarella, potato and caramelised onion on the dough, and scatter the thyme over. Season and drizzle with olive oil.

Notes

We used Odem potatoes for the topping, but any good baking potato will do.
