Tartiflette: Bacon & Reblochon Potato Bake Tips, FAQ & printable recipe

Tips for success

For the best texture, slice the potatoes uniformly — about 1/4-inch thick — so they cook evenly. Parboiling them just until a knife meets slight resistance is key; they'll finish cooking in the oven.

When caramelizing the onions, use medium-low heat and stir occasionally. If they start to stick, add a splash of water or wine. The lardons should be thick-cut for a meaty bite, and you can use regular bacon cut into pieces if lardons aren't available.

Reblochon has a distinctive flavor that's hard to replace, but if you must, choose a cheese that melts well and has a washed rind, like Port Salut or Saint-Nectaire. Avoid overmixing the potatoes with the cream — fold gently so they don't break.

For a deeper crust, you can finish the tartiflette under the broiler for a minute or two, but watch it closely. Serve with a crisp green salad dressed with vinaigrette to cut through the richness.

Variations

• Smoky Bacon Swap: For a deeper smoky flavor, use smoked bacon lardons and add a pinch of smoked paprika along with the onions. You can also use pancetta for a less smoky, more delicate taste.
• Vegetarian Version: Omit the bacon and sauté the onions in extra butter or olive oil. Add a handful of sliced mushrooms with the onions for an earthy, meaty texture. Use vegetable broth instead of wine, or keep the wine for acidity.
• Herbed Potato Tartiflette: Fold in fresh thyme leaves or chopped rosemary with the potatoes before adding the cream. The herbs complement the cheese and bacon beautifully. Add a pinch of nutmeg to the cream for extra warmth.
• Extra Crispy Top: After baking, sprinkle the top with a little grated Gruyère or breadcrumbs and broil for 1 to 2 minutes until deeply browned. This adds a crunchy contrast to the creamy interior.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 4 days. The gratin will firm up when cold; reheat gently.

Freezer

Freeze in an airtight container for up to 2 months. Thaw overnight in the refrigerator before reheating in a 350°F (175°C) oven until hot and bubbling.

Reheat

Reheat individual portions in the microwave in 1-minute intervals, or place the whole skillet in a 350°F (175°C) oven for 15 to 20 minutes.

Leftover tartiflette can be stored in an airtight container in the refrigerator for up to 4 days. Reheat in the oven at 350°F (175°C) for 10 to 15 minutes, or in the microwave in 1-minute increments until hot. The cheese may lose its crisp top but will still be deliciously creamy. If the gratin seems dry when reheating, add a splash of cream or milk before warming.

You can assemble the tartiflette up to a day ahead: prepare the bacon-onion-wine mixture, fold in the potatoes and cream, and place the Reblochon on top. Cover and refrigerate.

When ready to bake, add 10 to 15 minutes to the baking time, starting from a cold dish. Let it come to room temperature for 30 minutes before baking for more even cooking. This makes it a great option for entertaining.

Serving ideas

Serve tartiflette hot, straight from the skillet, with a large spoon to crack through the blistered cheese rind.

It's a hearty main course that pairs beautifully with a simple green salad dressed with lemon and olive oil, or with crusty baguette to mop up the creamy sauce. For a ski-lodge feel, serve with cornichons and pickled onions — their acidity balances the richness.

This dish also works as a side for roasted meats or as part of a winter spread. The portions are generous, so one skillet easily feeds 6 as a main or 8 as a side. Pair it with a dry white wine like Apremont or a light red like Pinot Noir from the Savoie region. The tartiflette is best enjoyed immediately, while the cheese is molten and the top is crisp.

Tartiflette: Bacon & Reblochon Potato Bake

Prep 20 minCook 45 minTotal 1 h 5 minServes 6

Ingredients

• 200 g thick-cut smoked bacon lardons
• 2 tbsp unsalted butter
• 2 yellow onions, thinly sliced
• 100 ml dry white Savoie wine
• 800 g waxy potatoes, parboiled and sliced
• 50 ml heavy cream
• 450 g Reblochon cheese wheel, halved horizontally

Instructions

1. Heat a 10-inch cast-iron skillet over medium heat. Add the bacon lardons and cook, stirring occasionally, until crisp and browned, about 6 to 8 minutes. Transfer the lardons to a plate with a slotted spoon, leaving the rendered fat in the skillet. Add the butter to the skillet, then the sliced onions. Cook, stirring often, until the onions are deeply golden and caramelized, about 12 to 15 minutes. Return the bacon to the skillet.
2. Pour the dry white wine into the skillet with the onions and bacon. Scrape up any browned bits from the bottom of the pan. Let the wine bubble and reduce by half, about 2 to 3 minutes, until the liquid is almost syrupy and the alcohol has cooked off.
3. Add the parboiled sliced potatoes to the skillet. Fold gently with a wooden spoon to combine with the bacon and onions. Pour the heavy cream over the potatoes and fold again until every slice is lightly coated. Spread the mixture into an even layer, pressing down lightly.
4. Place the halved Reblochon cheese wheel over the potato mixture, rind side up. Press it gently so it sits snugly on top. The cheese will melt and spread as it bakes, covering the potatoes completely.
5. Heat the oven to 400°F (200°C). Place the skillet in the oven and bake for 25 minutes, until the cheese is melted, bubbling, and the top is blistered and browned in spots. The edges of the potatoes should be crisp and golden.
6. Remove the skillet from the oven and let the tartiflette rest for 5 minutes. This allows the cheese to set slightly so it doesn't run off the spoon. Serve hot, scooping through the blistered cheese rind to lift out the cheesy, wine-scented potatoes.
