📌 Tartagnarde
Posted 5 May 2026 by: Admin
The aroma wafting from the oven when the Tartagnarde starts to brown—melted cheese, smoked bacon, pastry turning crisp—perfectly explains why mountain recipes were invented. It’s a rustic dish, designed for weekends when you have time on your hands. No complicated techniques, just well-thought-out layers and a spectacular reveal.
The Tartagnarde is presented like an upside-down Tatin tart: the golden turkey bacon forms a coppery crust on top, with the layers of potato and tomme cheese visible when sliced. The tomme melts slowly between the layers—not as a liquid sauce, but in short, creamy strands that stretch slightly when you pull a serving away. The puff pastry, which was on top during baking, ends up on the bottom after flipping, crispy and buttery with baking bubbles frozen in the dough. The whole dish radiates a dense heat, comforting in the most physical sense of the word.

Ingredient Notes
Everything you need for a generous Tartagnarde: tomme de Savoie, potatoes, smoked turkey bacon, and puff pastry.
- Tomme de Savoie : This is the soul of the dish. Look for an artisanal tomme if you can find it—with its grey rind and firm ivory paste. It melts without running, unlike more humid industrial cheeses. Avoid vacuum-packed versions that are too compressed: they release liquid during cooking and soak the layers.
- Smoked turkey bacon : It works perfectly in this role. Get thin slices but not translucent—too thin, they disappear; too thick, they stay soft in the middle. During baking, the edges caramelize slightly, releasing a gentle smoke that perfumes the entire creamy filling.
- Potatoes : Firm-fleshed varieties are mandatory: Charlotte, Amandine, or Nicola. No floury varieties that fall apart when cooked. They must hold their shape in rounds after two cookings—one in water, one in the oven.
- Heavy cream (Crème fraîche) : Thick, not liquid. A liquid version would make the filling too runny—it would escape between the layers before setting. A cream with 30% fat binds the eggs well and stays inside the filling.
- Puff pastry : All-butter store-bought pastry is more than enough. What matters: prick it with a fork before baking so it doesn’t puff up into a giant hollow bubble in the center.
Potatoes—Round One
Peel and slice the potatoes into rounds about 5 mm thick—not too thin (they would mash), nor too thick (they would stay crunchy in the middle). Par-cook them for 10 to 12 minutes in well-salted boiling water. The test: the tip of a knife goes in, but you feel a slight resistance. Perfect. Drain and let cool uncovered—the evaporating moisture is important; you don’t want trapped steam in the layers after assembly. Meanwhile, preheat the oven to 180°C.
The creamy filling in two minutes
In a large bowl, whisk the three eggs with the heavy cream until smooth. Add the grated cheese, a good pinch of freshly grated nutmeg—the bottled powder really doesn’t have the same punch—plenty of black pepper, and a few thyme leaves rubbed between your fingers to release their oils. Salt: go very easy. The turkey bacon and tomme already salt the filling considerably. Whisk for another thirty seconds. That’s it.
Assembling the layers
Assembly happens in the cold mold. First, line the bottom with turkey bacon slices, overlapping them slightly—like roof tiles, but in a circle. Add a layer of potato rounds, then pieces of tomme, then pour about half of the creamy mixture evenly over it. Repeat if the height of the mold allows. Always finish with a layer of potatoes: this will be in contact with the pastry and form a stable base after flipping.
The pastry, the oven, the patience
Unroll the puff pastry on top. Tuck the edges inside the mold with your fingers, like tucking in a bed. Prick the surface with a fork—about ten well-distributed holes, no more. Bake for 40 to 45 minutes. From 35 minutes onwards, watch the color: the pastry should reach a light caramel gold, not dark brown. The cheese bubbling slightly under the pastry makes a muffled, almost crackling sound. That’s a good sign.
The flip—don’t rush it
Let it rest for at least 8 minutes before flipping. Not 2 minutes, not 15—8 minutes. The filling needs to stabilize, otherwise it will collapse when unmolded. Place a large serving plate flat over the mold, press down firmly with both hands, and flip in one decisive motion. Lift the mold slowly. The caramelized turkey bacon appears on top, slightly shiny, with smoky steam rising. Serve immediately while the cheese still stretches between the layers.
Tips & Tricks
- Don’t cook the potatoes completely in the water—they finish in the oven for 40 minutes. If they go into the mold soft, they come out as mash.
- A springform pan is much more practical for unmolding. With a classic mold, flipping is risky if the filling is still too liquid in the center.
- A clove of garlic tucked between the layers with the tomme changes everything—without dominating, it provides an aromatic background reminiscent of tartiflette.
Can I prepare the Tartagnarde in advance?
Yes, you can assemble the tart the day before up to the puff pastry step, cover the mold, and refrigerate. The next day, take it out 20 minutes before baking so the filling isn’t cold in the middle. Baking time remains the same.
What cheese can replace Tomme de Savoie?
Reblochon works very well and gives an even meltier result, very close to a tartiflette. Raclette cheese is also a solid option. Avoid overly wet cheeses like mozzarella, which would release too much liquid during baking.
How to store and reheat leftovers?
Leftovers keep for up to 3 days in the refrigerator in an airtight container. To reheat, place portions in the oven at 170°C for 10 to 12 minutes—the microwave softens the pastry, and it’s hard to fix afterward.
Will a classic cake pan work without a springform pan?
Yes, but flipping is riskier. Ensure the edges of the mold are well-lined with the bacon slightly overlapping, and absolutely let it rest for 8 to 10 minutes before flipping so the filling is stabilized.
Why is the pastry soft on the bottom after flipping?
The moisture released by the filling during cooking can soften the pastry if it isn’t well-baked before flipping. Check that the pastry is deep golden on top before taking it out—if the top is golden, the bottom is cooked. Flipping too quickly without resting time is also a frequent cause.
Can I make a vegetarian version?
Yes. Remove the turkey bacon and replace it with thinly sliced red onions caramelized in a pan, or mushrooms browned in olive oil. The structure of the dish works the same way, but be sure to drain the mushrooms well to avoid excess moisture.

Main course
A savory mountain-style Tatin tart: caramelized turkey bacon, melting Tomme de Savoie, and tender potatoes under a crispy puff pastry, spectacularly flipped just before serving.
Ingredients
- 800g firm-fleshed potatoes (Charlotte or Amandine)
- 600g tomme de Savoie
- 250g sliced smoked turkey bacon (about 24 slices)
- 100g grated emmental or gruyère
- 3 eggs
- 200ml heavy cream / crème fraîche (30% fat)
- 1 all-butter puff pastry (approx. 230g)
- 4 sprigs of fresh thyme
- 1 pinch freshly grated nutmeg
- 1 clove of garlic (optional)
- salt and freshly ground black pepper
Instructions
- 1Peel the potatoes and cut into 5 mm rounds. Par-cook for 10 to 12 minutes in a pot of boiling salted water—they should be slightly tender but still firm. Drain and let cool uncovered.
- 2Preheat the oven to 180°C. In a bowl, whisk the eggs with heavy cream, grated cheese, nutmeg, pepper, and thyme. Salt very lightly.
- 3Cut the Tomme de Savoie into thick slices (about 1 cm). Set aside.
- 4Line the bottom of the mold with turkey bacon slices, overlapping them slightly like a rosette of tiles.
- 5Arrange a layer of potato rounds on the bacon, then the tomme slices, then pour half of the creamy mixture. Repeat if the mold allows. Finish with a layer of potatoes.
- 6Unroll the puff pastry on top, tuck the edges inside the mold, and prick the surface with a fork (about ten holes).
- 7Bake for 40 to 45 minutes until the pastry is light caramel golden. Let rest for 8 minutes out of the oven.
- 8Place a large plate on the mold, press firmly, and flip decisively. Lift the mold slowly. Serve immediately.
Notes
• Storage: up to 3 days in the refrigerator in an airtight container. Reheat in the oven at 170°C for 10 to 12 minutes to regain pastry crispiness.
• Cheese variant: replace the tomme with reblochon (for a meltier result) or raclette cheese for a milder version.
• Make ahead: the tart can be assembled the day before up to the pastry step, kept in the fridge, and baked the next day after 20 minutes at room temperature.
