Tartiflette is a warm, bubbling potato bake from the Savoy region of the French Alps, made with Reblochon cheese, onions, and pork lardons. This version layers tender potatoes with browned bacon, a splash of white wine, and melting cheese for a rich, comforting dish that is served straight from the oven; family and regional versions vary in their seasonings and proportions.
Ingredients
- 2.2 lb (1 kg) waxy or all-purpose potatoes, such as Yukon Gold, peeled and cut into 1½-inch (4 cm) pieces
- 6 oz (170 g) thick-cut smoked bacon or pork lardons, cut into short batons
- 1 medium yellow onion, about 5 oz (150 g), thinly sliced
- ½ cup (120 ml) dry white wine, such as a crisp Savoy-style wine or another dry white
- 1 Reblochon cheese, about 17½ oz (500 g), cut horizontally into two thinner rounds
- 1 garlic clove, halved
- 1 tablespoon (15 ml) neutral oil, only if the bacon does not release enough fat
- ¼ teaspoon (1 g) freshly ground black pepper, plus more to taste
- ⅛ teaspoon (0.3 g) freshly grated nutmeg, optional
- Fine salt, for the potato water and seasoning as needed
Instructions
- Heat the oven and prepare the dish. Set a rack in the center and heat the oven to 400°F (200°C). Rub the cut sides of the garlic over the bottom and sides of a shallow 2½- to 3-quart (2.4- to 2.8-liter) baking dish, then lightly grease the dish if it is not naturally nonstick. Keep the garlic clove for the potatoes or discard it. Put a large pot of salted water on to boil while you prepare the other ingredients.
- Parboil the potatoes. Add the potato pieces to the boiling water and simmer for 12–15 minutes, until a knife slides into an edge but the centers still offer slight resistance. They should not be falling apart; they will finish cooking in the oven. Drain them well and let them steam in the colander for 2 minutes so excess moisture evaporates. If the pieces are unusually large, cut them into bite-size chunks after draining.
- Brown the bacon and onion. While the potatoes cook, put the bacon in a large skillet over medium heat. Cook for about 7–9 minutes, turning occasionally, until browned and much of its fat has rendered. Check the thickest pork pieces with a food thermometer: USDA FSIS gives 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of pork. Rest the cooked pieces for 3 minutes before continuing. If using bacon pieces too small to check reliably, cook them thoroughly until hot and crisp. Pour off excess fat, leaving about 1 tablespoon in the pan; add the oil only if the pan looks dry.
- Soften the onion and reduce the wine. Add the sliced onion to the skillet and cook over medium-low heat for 5–6 minutes, stirring, until soft and lightly golden rather than deeply browned. Pour in the white wine and scrape up the browned bits. Simmer for 2–3 minutes, until the sharp alcohol smell has eased and the liquid has reduced slightly. Stir in the pepper and optional nutmeg. Taste before adding salt because bacon and cheese can both be quite salty.
- Layer the tartiflette. Arrange half the drained potatoes in the baking dish and spoon over half the onion-and-bacon mixture. Add the remaining potatoes, then the rest of the onion mixture. Cut the Reblochon horizontally into two rounds if it has not already been prepared. Set the halves on top, cut side down, so the rind faces upward and the soft interior melts down through the layers. If the cheese is too firm to slice neatly, leave it at room temperature for a few minutes or ask for it to be cut at the cheese counter.
- Bake until bubbling. Bake uncovered at 400°F (200°C) for 25–30 minutes. The cheese should be melted and golden in spots, with bubbling juices around the edges, and the potatoes should be completely tender when pierced. If the top is pale after the dish is hot, move it under the broiler for 1–2 minutes, watching closely so the rind does not scorch. Let the tartiflette stand for 5 minutes before serving; this short rest helps the layers settle but keeps the dish warm and spoonable.
Tips
- Choose potatoes that hold their shape. Waxy potatoes or Yukon Golds stay intact through parboiling and baking. Very floury potatoes can still work, but they soften more readily, so check them early and drain as soon as a knife meets slight resistance.
- Use Reblochon if you can find it. This soft, washed-rind cheese is the characteristic choice and gives the bake its creamy center and savory aroma. If it is unavailable, use an equal weight of another soft, meltable washed-rind cheese, such as Taleggio; the flavor will be less specifically Alpine. Brie is a milder, widely available fallback, though its texture and rind aroma differ.
- Keep the filling moist, not watery. Drain the potatoes thoroughly and reduce the wine for a couple of minutes before layering. If the dish looks dry, add 2 tablespoons (30 ml) of wine or broth; if it looks wet, give the potatoes another minute or two to steam-dry.
- Season at the end. Bacon, Reblochon, and the potato cooking water all contribute salt. Taste the onion mixture before adding any, and avoid salting the finished layers heavily. A little black pepper is usually enough to balance the richness.
Serving Suggestions
Serve tartiflette hot, directly from its baking dish, while the cheese is still soft and the potato layers are easy to scoop. It is substantial, so a modest portion alongside a crisp green salad is often enough for a meal. Dress lettuce, endive, or frisée with a sharp vinaigrette made with vinegar or lemon; that fresh acidity provides contrast without competing with the cheese.
For a larger table, offer cornichons, pickled onions, or a small bowl of lightly dressed greens. These bring a bright, tangy counterpoint to the smoky bacon and rich cheese. A dry white wine from the Savoy region is a traditional-style pairing, but any crisp, unoaked white wine works well. For a nonalcoholic drink, sparkling water with lemon or unsweetened iced tea keeps the meal refreshing.
Bring the dish to the table after its five-minute rest, and let people serve themselves. The cheese will remain molten at first, then thicken as it cools. If serving with bread, choose a simple crusty loaf for catching the sauce rather than a heavily seasoned bread. Tartiflette is best treated as the centerpiece rather than one item among several rich sides.
Variations
Make it without wine: Replace the ½ cup (120 ml) white wine with ½ cup (120 ml) low-sodium chicken or vegetable broth and 1 teaspoon (5 ml) lemon juice or white wine vinegar. The broth adds savory depth, while the small amount of acid supplies some of the lift that wine would bring. Let the broth reduce briefly, just as you would the wine.
Use a different cheese: If Reblochon is hard to source, use Taleggio for a supple, savory melt, or Brie for a milder, creamier result. Keep the amount close to 17½ oz (500 g), and leave the rind on if it is edible. Avoid very aged, hard cheeses as the sole replacement; they will not produce the same soft layer. A little grated Gruyère can be added for extra browning, but it should not replace all the soft cheese.
Adjust the pork: Use smoked bacon, unsmoked bacon, or traditional-style lardons according to what is available. Smoked bacon makes the dish more pronounced, while unsmoked bacon lets the cheese and onion come forward. For a meat-free version, omit the pork and sauté 8 oz (225 g) sliced mushrooms with the onion in 1 tablespoon (15 ml) butter or oil. The result is not the classic combination, but the mushrooms add a satisfying savory flavor.
Add herbs or extra vegetables sparingly: A few thyme leaves stirred into the onion mixture complement the potatoes, and a handful of sliced leeks can be cooked with the onion. Keep additions modest so the dish still bakes evenly and the Reblochon remains the main feature. Avoid adding raw vegetables with a high water content, such as zucchini, which can release liquid and make the layers loose.
Storage and Reheating
Refrigerate leftovers within 2 hours of baking, transferring them to a shallow airtight container once they are cool enough to handle. Keep them refrigerated for 3–4 days. The cheese firms as it chills, so the cold dish will be denser than it was straight from the oven; that is normal. Do not leave the tartiflette at room temperature for more than 2 hours, or more than 1 hour when the room is above 90°F (32°C).
For the best texture, reheat individual portions in an oven-safe dish at 350°F (175°C), covered loosely with foil, for about 20–25 minutes, removing the foil for the last 5 minutes if you want to refresh the browned top. Larger portions may need 30–40 minutes, depending on their depth. Reheat leftovers to 165°F (74°C) throughout, checking the center with a food thermometer. A microwave also works for one serving: cover it loosely and heat in short intervals, turning or stirring where possible, until the center reaches 165°F (74°C); the cheese will be softer and less browned.
You can freeze portions in airtight, freezer-safe containers for up to 2 months for best quality. Thaw overnight in the refrigerator, then reheat as above to 165°F (74°C). The potatoes may become a little softer and the cheese may separate slightly after freezing, but the dish will still be suitable to eat when handled and reheated safely. Avoid repeatedly cooling and reheating the same portion.
Frequently Asked Questions
Can I assemble tartiflette ahead of time?
Yes. Cook and drain the potatoes, prepare the bacon and onion mixture, and assemble everything in the baking dish up to 24 hours ahead. Cover and refrigerate it, then bake until hot and bubbling. Because it starts cold, allow extra time—often 10–15 minutes—and check that the center is hot before serving. For the most even bake, add the cheese immediately before it goes into the oven.
Do I remove the rind from Reblochon?
No. Leave the rind on and place the cheese cut side down, rind side up. The rind softens as it bakes and contributes flavor to the top. If you prefer a less pronounced rind flavor, you can trim a little away, but removing it all is unnecessary and may make the cheese spread more quickly.
Why is my tartiflette watery?
The most common causes are potatoes that were not drained well, wine that was not reduced, or vegetables that released extra liquid. Let parboiled potatoes steam-dry in a colander, simmer the wine briefly, and avoid packing in watery additions. A shallow baking dish also helps moisture evaporate. If the finished dish has a little liquid around the edge, allow it to rest for 5–10 minutes before serving.
Can I make tartiflette without peeling the potatoes?
Yes, if the skins are thin and clean. Scrub them well, remove any eyes or damaged spots, and cut them into even pieces so they cook at the same rate. Leaving the skins on gives the dish a more rustic texture. If using thick-skinned potatoes, peeling them usually makes the layers softer and easier to scoop.
What can I use instead of Reblochon?
Taleggio is a useful substitute because it melts smoothly and has a savory washed rind, though it tastes different from Reblochon. Brie is easier to find in many shops and gives a milder result. Use about 17½ oz (500 g), and keep in mind that different cheeses vary in saltiness, moisture, and how quickly they brown. If your substitute is particularly salty, hold back on seasoning the potato layers.
Is tartiflette a complete meal?
It can be served as a hearty main dish, especially with a green salad or lightly pickled vegetables. The traditional-style combination is rich and filling, so a simple, fresh side is usually more balanced than another creamy or starchy dish. For a larger meal, serve smaller portions alongside vegetables such as green beans or a crisp cabbage salad.
