The name Tartiflette comes from the old Savoyard word tartiflâ, which means potato. While the dish is inspired by older mountain recipes, the version we know today became popular in the 1980s and is now one of the most famous comfort foods in France.

You’ll often find Tartiflette served in ski resorts after a day on the slopes. It’s warm, filling, and perfect for sharing with family and friends during the colder months.

Why You’ll Love This Tartiflette Recipe
This is one of my favorite French comfort food recipes because it is simple to make but tastes like something from a cozy mountain restaurant.

The potatoes become soft and creamy, the bacon adds a smoky flavor, and the melted cheese creates a rich, golden topping that everyone loves.

It’s also a great recipe for sharing. Serve it for a family dinner or a weekend meal with friends, and watch everyone come back for seconds.

Why Reblochon Cheese Is Special
Reblochon is the traditional cheese used to make Tartiflette. It comes from the French Alps and has a soft, creamy center with a mild, nutty flavor. As it bakes, it melts into the potatoes and creates the rich sauce that makes this dish so famous.

If you live in the United States, you may not be able to find authentic Reblochon. That’s because it is made from raw milk and is not old enough to meet US import rules.

The good news is that you can still make a delicious Tartiflette. Soft cheeses like Taleggio, Brie, Camembert, Port Salut, or Raclette all melt beautifully and make excellent substitutes.

Key Ingredients & Substitutions for Tartiflette
Waxy potatoes – 1 kg (2.2 lbs): Waxy potatoes hold their shape as they bake, making them the best choice for Tartiflette. Yukon Gold potatoes are an easy substitute and work beautifully.

Bacon or lardons – 200 g (7 oz): Traditional Tartiflette is made with French lardons, but thick-cut bacon cut into small pieces works just as well. It adds a rich, smoky flavor to the dish.

Large onion – 1: A sliced onion becomes soft and sweet as it cooks, adding extra flavor to every layer.

Dry white wine – ¼ cup (60 ml), optional: A splash of dry white wine adds a little freshness and balances the rich cheese. Sauvignon Blanc or Pinot Grigio are both great choices.

Heavy cream – ¼ cup (60 ml): Just a little cream helps bring everything together and creates a rich, creamy sauce as the cheese melts.

Reblochon cheese – 1 whole wheel (about 450 g / 1 lb): Reblochon is the traditional cheese for Tartiflette. It melts into a rich, creamy sauce with a mild, nutty flavor. Leave the rind on—it adds extra flavor while baking.

Salt and black pepper – to taste: Season lightly, as the bacon and cheese are already quite salty.

The Best Reblochon Cheese Substitutes
Reblochon is the traditional cheese for Tartiflette, but it can be difficult to find outside France. Luckily, several cheeses melt just as well and make delicious substitutes.

Taleggio – one of the easiest replacements to find and very close in texture.
Raclette cheese – rich, creamy, and perfect for Alpine recipes.
Brie – mild, creamy, and easy to find in most grocery stores.
Camembert – similar to Brie with a slightly stronger flavor.
Port Salut – soft, creamy, and melts beautifully.
No matter which cheese you choose, leave the rind on. It helps create the golden, bubbly top that makes Tartiflette so special.

Choosing the Best Potatoes
The best potatoes for Tartiflette are waxy potatoes because they stay firm after boiling and baking. They hold their shape between the layers instead of falling apart.

If you can’t find waxy potatoes, Yukon Gold potatoes are an excellent choice. Try not to use very starchy potatoes like Russets, as they can become too soft after baking.

Equipment You’ll Need
Large pot: For boiling the potatoes.
Large skillet: For cooking the bacon and onions.
Baking dish: A 9×13-inch baking dish or similar size works well.
Knife and cutting board: For slicing the potatoes, onions, and cheese.
Slotted spoon: Helpful for lifting the potatoes out of the water without breaking them.
Step-by-Step Instructions for Tartiflette
1. Boil the Potatoes
Place the whole potatoes in a large pot and cover them with cold salted water. Add a few sprigs of fresh thyme if you like. Bring to a boil, then lower the heat and cook for about 15 to 20 minutes.

The potatoes should be just tender when pierced with a knife. Do not overcook them, or they may fall apart later. Drain and let them cool for a few minutes.

2. Slice the Potatoes
When the potatoes are cool enough to handle, cut them into rounds about ¼ inch thick. Try to keep the slices even so they cook at the same rate in the oven.

3. Cook the Bacon
Place the bacon or lardons in a large skillet. Start with a cold pan, then cook over medium-low heat until the bacon is golden and crisp.

Remove a little bacon for the top if you like. Leave the rest in the pan with the bacon fat.

4. Cook the Onion
Add the sliced onion to the skillet with the bacon. Cook for about 5 to 7 minutes, or until the onion is soft and lightly golden.

If using white wine, pour it into the pan and stir well. Cook until most of the wine has reduced. Season with a little black pepper and only a small amount of salt, since the bacon and cheese are already salty.

5. Heat the Oven
Preheat the oven to 400°F (200°C). Lightly grease a medium baking dish or use an oven-safe skillet.

6. Layer the Tartiflette
Place half of the sliced potatoes in the baking dish. Spoon half of the bacon and onion mixture over the potatoes.

Add the rest of the potatoes, then spread the remaining bacon and onions over the top.

7. Add the Cheese and Cream
Cut the Reblochon cheese in half across the middle so you have two thinner rounds. Place both halves on top of the potatoes with the rind facing up.

Pour the heavy cream around the cheese and over the potatoes. Add a little fresh thyme or the saved crispy bacon on top if you like.

8. Bake Until Golden
Bake uncovered for 20 to 25 minutes. The cheese should be fully melted, bubbling around the edges, and golden on top.

If the top needs more color, place it under the broiler for 1 to 2 minutes. Watch it closely so it does not burn.

9. Rest and Serve
Let the Tartiflette rest for 5 minutes before serving. This gives the cheese and cream time to settle and makes the dish easier to scoop.
