Are you looking for an alpine one-dish meal, the kind that goes to the table in its dish and needs nothing else beside it?

Then tartiflette is what you want. I will walk you through this Savoyard gratin of potatoes, bacon and onions, topped with half a reblochon that melts and runs into every layer.

The step nearly everyone skips is browning the potatoes. Boiled to al dente and then returned to the pan in the bacon fat, they take on colour and flavour and stay whole under the cheese instead of falling apart. That is the difference between a tartiflette and gratinated boiled potatoes.

There are at least three good reasons to make it: five ingredients, an hour of work, and a level of satisfaction that settles a whole dinner without anything else.

Reblochon is the cheese of the original recipe and goes in cut horizontally, crust side up: as it melts it releases its cream downwards. If you cannot find it, taleggio behaves very similarly, with a slightly different character but an equally convincing result.

Serve it piping hot, just rested, with a green salad dressed sharply. This is not decoration: it genuinely balances how rich the dish is.

Ready? Let’s get started with tartiflette.

Steps

  1. Boil the potatoes whole in their skins for 20 minutes, just until al dente. Let them cool slightly, peel them and cut them into half-centimetre slices.
  2. Fry the bacon in a wide pan with no added fat over medium heat, until golden and it has released its fat. Lift it out with a slotted spoon and set aside.
  3. In the same pan, soften the sliced onions for 8 minutes, then deglaze with the white wine and let it evaporate completely.
  4. Add the potato slices and brown them in the pan juices for 5 to 6 minutes, turning gently: this browning is what separates a flavourful tartiflette from plain boiled potatoes under cheese.
  5. Rub a baking dish with the cut garlic clove, then layer half the potatoes, half the bacon and a drizzle of cream, and repeat with the rest, salting very lightly and peppering generously.
  6. Cut the reblochon in half horizontally and lay it crust side up over the potatoes, covering the whole surface.
  7. Bake at 200°C (400°F) for 25 to 30 minutes, until the cheese is fully melted and golden at the edges. Rest for 5 minutes and serve piping hot.

Helpful tips

Boil the potatoes only until al dente and then brown them: fully cooked they collapse in the oven and the tartiflette turns to mash.

Season with restraint: bacon and cheese already bring plenty of salt.

If you cannot find reblochon, use a soft washed-rind cheese such as taleggio, which behaves in a very similar way.

Serve it with a sharply dressed green salad: it balances the richness rather than just filling the plate.
