3 Toss the potatoes, leeks and pancetta together with the olive oil and rosemary. Season to taste, then tip the mixture into a shallow ovenproof dish.

4 Scatter the grated Gruyère over the top of the potato mixture and bake in the preheated oven for 20 minutes, until golden and crispy on top. Garnish with the rosemary sprigs and serve immediately.
