Tartiflette – a French dish that everyone will love
Tartiflette is the famous Alpine French casserole that has become a global comfort-food favourite — at first glance just another potato-and-meat bake, but in execution a true masterpiece of layered simplicity. The dish layers blanched potatoes with golden sautéd bacon and onion, drowns them in cream, and crowns the top with reblochon cheese that melts into a deeply browned crust during baking.
The flavour comes almost entirely from the quality of three ingredients: well-marbled bacon, real cream, and the right cheese. Reblochon is the traditional choice, but camembert or any soft mould cheese produces an excellent result if reblochon is hard to find or unaffordable.
Ingredients
Show ingredients
- pork belly or bacon – 300 g;
- white onion – 200 g;
- olive oil – 50-70 g;
- potatoes – 700 g;
- reblochon cheese or camembert – 200 g;
- any soft cheese – 100 g;
- heavy cream – 200 ml;
- salt, pepper – to taste.
Preparation
- I prepare the ingredients. The bacon should have visible fat — both smoked and unsmoked work, with smoked giving a more assertive flavour. Reblochon (the traditional choice) is rare and expensive outside France; camembert or any soft mould-rind cheese is an excellent substitute. Mixing two cheeses (the soft mould cheese on top + a milder soft cheese for the layer below) is also valid. Cream should be 22% or 33% fat — anything less risks splitting in the oven.
- I slice the onion into thin half-moons and separate the layers from each other so they cook evenly in the pan.
- I cut the bacon into 2 cm batons. Substantial pieces (rather than fine dice or thin strips) are key — I want to taste meaty bacon chunks in the casserole, not have them disappear into the cream.
- I pour the olive oil into a skillet, add the bacon batons, and place over medium heat.
- I render the bacon gently — the goal is to release the fat without crisping the meat into hard lardons. The bacon should be golden and translucent at the edges, still soft and bendable in the middle.
- I add the sliced onions to the rendered bacon and its fat.
- I cook the onions until soft and lightly golden, then season with salt and pepper to taste. No other spices — herbs, garlic, paprika would all overpower the cheese, which is the dish's headline flavour. I take the skillet off the heat and set aside.
- I slice the potatoes into 5-7 mm rounds. Uniform thickness ensures uniform cooking; varied slices leave some pieces underdone and others mushy.
- I drop the potato rounds into boiling water and blanch only until the water returns to the boil — this short par-cook cuts the eventual oven time and ensures the potatoes are tender by the time the cheese has melted. A tablespoon of vinegar in the blanching water keeps the rounds from breaking apart at the edges (the acid firms up the surface starches).
- I lift the par-cooked potatoes out with a slotted spoon and transfer to a plate to cool slightly. Working quickly here keeps the rounds from continuing to cook in the residual heat of the water.
- I slice the reblochon (or camembert) into pieces about 5-7 mm thick. Keeping the rind on is correct — it crisps up beautifully during baking and adds textural contrast.
- I grate the second (softer) cheese coarsely. This goes in the middle layer of the casserole where it melts smoothly into the cream and binds everything.
- I preheat the oven to 180 °C. I arrange the par-cooked potato rounds in a single layer at the bottom of an ovenproof baking dish and season with a little salt.
- I divide the bacon-and-onion mixture in half and spoon the first half evenly over the potato base.
- I add a second layer of potato rounds on top of the bacon, again seasoning with a light pinch of salt.
- I distribute the remaining bacon-and-onion mix on top, including any rendered fat from the skillet — this fat carries concentrated flavour and helps season the upper potato layer from above.
- I pour the cream evenly over the entire surface. The cream slowly works its way down through the layers during baking, infusing every potato slice.
- I sprinkle the grated soft cheese in a thin even layer across the top.
- I lay the reblochon (or camembert) slices in a tile pattern across the top, covering the entire surface. The dish goes onto the middle rack of the preheated oven for 30 minutes, until the top is deeply golden and bubbling at the edges.
The finished tartiflette comes to the table straight from the oven, bubbling and aromatic. A glass of dry white wine — preferably an Alpine white like Apremont or Roussette — is the traditional pairing. Tender cream-soaked potatoes, juicy bacon batons, and the unmistakable funk of melted soft cheese combine into the comfort-food magic that has made tartiflette a winter staple far beyond its French Alps origins.
Tips and Tricks
Tip 1. WAXY POTATOES OVER FLOURY. Use waxy or all-purpose potatoes (Charlotte, Désirée, Yukon Gold) rather than floury baking potatoes (King Edward, Russet). Waxy varieties hold their shape through the par-boil and the long oven bake; floury varieties disintegrate into a starchy mush. The structural integrity of the potato layer is what gives tartiflette its character — without it, the dish becomes a vague gratin.
Tip 2. CHEESE SUBSTITUTES IN HIERARCHY. Real reblochon is the gold standard — its washed rind and creamy paste are unmatched for melt and flavour depth. Best substitutes in order: 1) Camembert (closest in flavour and melt), 2) Brie (milder but excellent melt), 3) Pont l'Évêque (closer to reblochon's funk), 4) Tallegio (Italian washed-rind, very close in spirit). Avoid hard cheeses like cheddar or parmesan as the top layer — they melt into oily strings instead of a creamy crust. For another rich, layered French-inspired meat dish, see French-style meat from minced meat in the oven.
Tip 3. THE PAR-BOIL SAVES YOU 20 MINUTES OF BAKING. Skipping the brief par-boil means baking the potatoes from raw, which adds 25-30 minutes to the oven time and risks the cheese top going from golden to burnt before the potatoes finish. The 1-2 minute blanch in vinegared water is non-negotiable for the recipe's timing to work as written.
Tip 4. MAKE-AHEAD ASSEMBLY WORKS BEAUTIFULLY. Assemble the dish through step 18 (everything except the top reblochon layer) up to 24 hours ahead and refrigerate covered. When ready to serve, lay the reblochon slices on top and bake — add 10 extra minutes since you're starting cold. The flavours of the layers actually integrate better with this overnight rest.

Frequently Asked Questions
Can I make tartiflette without bacon?
Yes, with a flavour shift. Replace the 300 g bacon with the same weight of pancetta (closest match), guanciale (Italian cured pork cheek, even richer), smoked turkey for a leaner version, or sautéd mushrooms (200 g of cremini or wild mushrooms) for a vegetarian version. The vegetarian version loses the smoky-meaty backbone but gains its own earthy character — sauté the mushrooms in butter until deeply browned to maximise flavour. Add a pinch of smoked paprika to the onion stage to mimic the smoke note that bacon would have provided.
What's the right cheese-to-cream ratio?
The recipe uses 300 g total cheese (200 g reblochon-style + 100 g soft) plus 200 ml cream, which is a relatively dry tartiflette by French Alpine standards. For a more "swimming in cream" version, increase the cream to 300 ml and the soft cheese in the middle to 150 g. For a drier version, reduce cream to 150 ml. The ratios are forgiving as long as the top cheese layer is generous enough to form an unbroken golden crust over the whole surface.
Why did my tartiflette turn out greasy?
Three usual causes. First, the bacon was over-rendered — when bacon goes from soft to crispy, it releases too much fat into the dish. Stop the bacon at golden-edged-but-still-soft. Second, the cheese was too high in fat or too plentiful — stick to recipe quantities. Third, low-fat cream (under 20% fat) split during baking, releasing visible oily droplets. Use cream at 22% or higher; UHT cream is fine if fresh isn't available. Letting the finished tartiflette rest 10 minutes off the heat also helps the fat settle back into the dish rather than pooling on top.
Can I freeze tartiflette?
It freezes acceptably but not brilliantly. The potato texture firms up after thawing and the cream sometimes separates slightly on reheating. To freeze: cool the baked tartiflette completely, cut into portions, wrap each in foil, then in a freezer bag, and freeze up to 2 months. To reheat: thaw overnight in the fridge, then warm in a 160 °C oven covered with foil for 25-30 minutes (uncover for the last 5 to re-crisp the top). Fresh-baked is dramatically better than frozen-thawed; the make-ahead assembly approach (Tip 4) gives a much better result if you need to prep ahead.
