Tartiflette with bacon

Preheat the oven to 200°C, gas mark 6. Bring a saucepan of water to the boil. Halve the parsnips widthways. Cut the thick ends lengthways into 6-8 wedges, depending on size, and the thin ends into quarters. Cook the parsnips and potato in the water for 5 minutes to soften then drain. Cut the cheese into thin wedges (no need to remove the rind).

Heat a frying pan, preferably non-stick, and fry the pancetta for 3 minutes. Add the onion and fry for a further 4-5 minutes until softened and just beginning to colour. Add the garlic and cook for a further minute. Stir in the wine and bubble away until the liquid has almost evaporated.

Tip half the potatoes and parsnips into a shallow ovenproof dish and spread level. Arrange half the cheese wedges on top. Drain the onions and pancetta from the frying pan with a slotted spoon and arrange over the cheese. Scatter the remaining vegetables on top and arrange the rest of the cheese in a line down the centre.

Add the crème fraîche to the frying pan and stir over a gentle heat until the cream has melted. Pour over the cheese and vegetables. Bake for 30-35 minutes, covering with foil if the surface starts to over-brown, until the top is golden and bubbling and the vegetables are tender.
