Turn the oven on to 200 °C with top and bottom heat. It'll be hot by the time you need to bake.
Cook the potatoes
Peel the 430 g of potatoes, cut them into 5 mm slices, then drop them into a saucepan of cold salted water. Bring to a boil and let them simmer until they're easy to pierce with the tip of a knife.
Caramelize the onions
Thinly slice the 2 onions. Cook them in the skillet with the butter and olive oil over medium-low heat, stirring often, until golden and soft.
Tip · Stir regularly and turn down the heat as soon as things brown too fast. The onions should get soft and golden without burning, otherwise they turn bitter.
Add the bacon
Add the 80 g of smoked diced bacon to the onions and cook over medium heat until golden. Add pepper, no salt: the bacon and reblochon are already salty.
Drain and mix
Drain the potatoes well. Mix them in the skillet with the onions, bacon and the 5 cl of crème fraîche, then taste and adjust with pepper.
Prep the reblochon
Cut the 220 g of reblochon in half horizontally, like opening a book. Keep the rind on.
Build the dish
Pour the potato mix into the baking dish. Set both reblochon halves on top, rind side up.
Bake until golden
Bake at 200 °C until the cheese is fully melted and golden on top. Let it rest for 2 minutes before serving.
Tip · Serve with a green salad with a tangy vinaigrette, if you have one, to balance out the richness.
