Peel the 390 g of potatoes and cut them into 5 mm slices. Slice the 2 onions, slice the mushrooms, and cut the reblochon in half horizontally, then into slices.
Bring the water to a boil
Fill a saucepan with water, add the pinch of salt and bring to a boil over high heat.
Cook the potatoes
Drop the slices into the boiling water and let them simmer for 10 min, until a knife goes through with a little resistance. Drain them well. Meanwhile, preheat the oven to 200 °C.
Tip · Drain the potatoes well and don't cook them longer than stated, they finish cooking in the oven and fall apart if overcooked.
Brown the bacon
Heat the skillet with no added fat, add the 100 g of smoked diced bacon and brown it over medium-high heat, stirring. Lift it out with the spoon and keep the fat in the skillet.
Sauté the onions and mushrooms
Add the butter to the skillet, then the onions and let them soften for 5 min over medium heat. Add the mushrooms and cook them for 5 min until their water cooks off. Add pepper.
Tip · Don't salt the mushrooms at the start and don't crowd the skillet, otherwise they boil instead of browning. Serve the tartiflette with a green salad.
Mix the filling
Off the heat, put the bacon back in the skillet, add the 10 cl of crème fraîche and stir. Add the drained potatoes and toss gently.
Build the dish
Pour the mix into the baking dish and smooth the top. Lay the reblochon slices over the whole surface, rind side up.
Bake until golden
Bake at 200 °C for 15 min, until the cheese is melted and nicely golden. Let it rest for 2 min before serving.
