Preheat the oven to 200°C (180°C fan)/400°F/gas 6.
Cook the potatoes in boiling salted water for 15–20 minutes. Drain, leave to cool and then slice.
Melt the butter in a flameproof, round ceramic dish and fry the potatoes for 5–8 minutes until crisp. Remove and set aside. Add the lardons to the dish and fry for a few minutes, then add the onions and garlic and sauté for 5 minutes. Season, then deglaze the dish with the wine and pour in the double cream.
Remove the dish from the heat and layer the onion and lardon mixture with the potatoes and Reblochon. Bake in the oven for 30 minutes.
Serve and enjoy!
