When the cold winds of winter blow through the French Alps, locals turn to one dish that warms both body and soul: Tartiflette. This rich, creamy, and indulgent potato casserole is layered with Reblochon cheese, potatoes, onions, and smoky bacon – baked until golden and bubbling.

It’s rustic mountain cuisine at its finest – hearty, comforting, and perfect for sharing after a long day outdoors.

The Story Behind Tartiflette

Though it looks like a timeless traditional dish, Tartiflette is actually a modern classic. It was popularized in the 1980s by the Syndicat Interprofessionnel du Reblochon (the producers’ association) to boost the popularity of their cheese.

But the idea wasn’t new – it was inspired by the older “péla”, a Savoyard recipe of potatoes, onions, and cheese cooked in a pan. Tartiflette quickly spread across France and became an Alpine winter staple.

Ingredients You’ll Need

For 4 people:

1 Reblochon cheese (about 450 g, halved horizontally)

1.2 kg potatoes (waxy or all-purpose like Charlotte or Yukon Gold)

200 g smoked bacon lardons (or diced pancetta)

2 medium onions – thinly sliced

150 ml dry white wine (preferably from Savoie, like Apremont)

150 ml crème fraîche (or heavy cream)

2 tablespoons butter

Salt & freshly ground black pepper – to taste

👉 Optional: A touch of garlic or nutmeg can be added for extra depth.

Step-by-Step Recipe

1. Cook the Potatoes

Peel and slice the potatoes into thick rounds.

Boil them in salted water for 10–12 minutes until just tender but not mushy. Drain and set aside.

2. Prepare the Bacon and Onions

In a large skillet, melt butter and sauté the bacon lardons until lightly golden.

Add sliced onions and cook gently until soft and caramelized.

Deglaze with white wine and simmer for 2–3 minutes to let the alcohol evaporate.

3. Assemble the Tartiflette

Preheat oven to 200°C (400°F).

Butter a baking dish.

Layer half the potatoes at the bottom, season with salt and pepper.

Spread half of the bacon-onion mixture on top.

Add a spoonful of crème fraîche.

Repeat with the remaining potatoes and bacon mixture.

4. Add the Reblochon Cheese

Cut the Reblochon in half horizontally. Place the two halves rind-side up over the top of the dish (the rind helps create a golden crust as it melts).

5. Bake Until Golden

Bake uncovered for 20–25 minutes, until the cheese is bubbling, melted, and beautifully browned.

6. Serve

Remove from oven, let cool slightly, and serve hot.

Serving Suggestions

With a Fresh Salad: A green salad with vinaigrette balances the richness.

Wine Pairing: Serve with a chilled white wine from Savoie (Apremont, Roussette) or a light red like Gamay.

As a Main Dish: Tartiflette is hearty enough to be the star of the meal – just add bread and wine.

Variations

Vegetarian Tartiflette: Skip the bacon and add mushrooms or caramelized leeks.

Smoky Twist: Use smoked Reblochon or smoked cheese for deeper flavor.

Luxury Version: Add truffle shavings or wild mushrooms for a festive upgrade.

Tips for Success

Don’t Overcook Potatoes: Keep them firm so they hold their shape in the bake.

Use Authentic Reblochon: It’s the soul of tartiflette – creamy, nutty, and slightly pungent.

Let Cheese Brown: The bubbling, golden crust makes the dish irresistible.
