We think this tart requires a pastry chef’s hand and three hours of time. In reality, it’s based on a simple idea: pre-cooked potatoes, a puff pastry that steals the show, and a neatly arranged filling. The result looks elaborate, but the method is honestly easygoing.
When it comes out of the oven, the edges are puffed, golden, almost crumbly to the eye. The mozzarella melts between the potato slices and leaves a few white strands when you cut the first slice. The smoked turkey brings a warm, salty aroma without overpowering. With a crunchy salad on the side, the contrast really does the trick.

Ingredient Notes
Potatoes, puff pastry, mozzarella, smoked turkey, olive oil, salt and nutmeg: nothing complicated, but good basics are needed.
- Potatoes : They form the tender base of the tart and give that soft texture that contrasts with the puff pastry. Choose firm or all-purpose potatoes, slice them thinly, and stop the pre-cooking when they can be pierced without breaking.
- Puff pastry : It provides the crispiness and spectacular look without needing homemade pastry. Keep it well chilled when unrolling, because warm pastry sticks, deforms, and puffs less nicely in the oven.
- Smoked turkey : It adds a salty, slightly smoky note that wakes up the potatoes. Cut it into not-too-large strips so it spreads everywhere, or replace with shredded roasted chicken for a milder flavor.
- Mozzarella : It acts as a rich binder between the layers and brings that white creaminess that looks appealing as soon as you cut into it. Drain it thoroughly, especially if it’s in a ball, otherwise it may release too much water and soften the tart bottom.
- Olive oil : A drizzle is enough to round out the flavors and help the top brown. Don’t use too much: the potatoes should glisten lightly, not swim.
- Nutmeg : It adds depth to the potatoes, with a subtle warmth that you feel especially at the end of the mouth. Use just a pinch, because too much nutmeg quickly covers the cheese and makes the whole thing heavy.
Just-right potatoes
Start by peeling the potatoes, then cut them into thin, even slices. This regularity really matters: if some slices are thick, they will stay firm while others become almost melting. Pre-cook them in simmering salted water, not a rolling boil that knocks and breaks them. After about ten minutes, they should be tender under the knife tip, but still able to hold their shape. Drain them well and let the steam escape, because overly damp potatoes give a soft, sad pastry.
Well-prepared base
Unroll the puff pastry into the pan, keeping it on its paper if that helps you handle it cleanly. Prick the bottom with a fork to limit large air bubbles, but don’t press it down: the edge should be able to puff and become crispy. If the pastry becomes soft to the touch, put the pan in the fridge for a few minutes before filling. You should feel it become firm and cold under your fingers; that’s what will give a neater puff. This short rest also prevents the edges from collapsing during baking.
Neat layers
Arrange a first layer of potatoes on the bottom, slightly overlapping like tiles. Then add the smoked turkey in small pieces, followed by the well-drained mozzarella, without making large clumps in the center. The idea is not to load randomly, but to distribute the flavor so each slice has creaminess, saltiness, and crunch. Repeat the layers if your pan allows, then finish with a bit of mozzarella on top to get a golden surface in places. A drizzle of olive oil, a pinch of salt, and a dusting of nutmeg are enough: you should taste the potato, not just the seasoning.
Golden baking
Bake in a preheated oven at 180°C and let it cook until the edges are deeply golden. During baking, the mozzarella will melt gently and the pastry will crackle slightly on the sides. If the top colors too quickly while the bottom still seems pale, move the pan down a rack. The tart is ready when the edges are well puffed, the cheese is bubbling gently, and the center no longer wobbles like a liquid filling. The smell should be warm, buttery, with a subtle smoky note.
Useful resting
Don’t cut the tart as soon as it comes out of the oven, even if it smells wonderful. Let it rest a few minutes so the cheese stabilizes and the layers hold better under the knife. Cutting too quickly makes the filling slide and breaks the visual effect of the beautiful potato layers. Serve it warm rather than hot: the puff pastry stays crisp, the mozzarella remains creamy, and the flavors are clearer. With a well-dressed green salad, the richness of the tart immediately feels more balanced.
Tips & Tricks
- Drain the mozzarella and then pat it dry with paper towels, because its water can soak the pastry and prevent the bottom from becoming crispy.
- Cut the potatoes to even thickness, because uniform cooking gives a tender texture without hard pieces in the middle of the tart.
- Keep the pastry well chilled before filling, since puff pastry puffs better when the butter stays firm when it enters the oven.
- Let the tart rest before serving, because the cheese firms up slightly and slices cut more cleanly.
Can you prepare this tart in advance?
Yes, you can assemble it a few hours before baking and keep it chilled. It’s still best to bake it at the last moment to keep the pastry very crispy.
How to avoid a soggy tart bottom?
Drain the potatoes and mozzarella well before assembling. A too-wet filling quickly soaks the puff pastry, especially in the center.
Can you replace the smoked turkey?
Yes, you can use roasted chicken strips or grilled vegetables. The important thing is to choose a pre-cooked filling that isn’t too wet.
What cheese to use instead of mozzarella?
A grated cheese like Emmental, young Comté, or mild cheddar works very well. It often releases less water than mozzarella and gives a more gratinéed top.
How to reheat leftovers?
Reheat slices in the oven at 160°C for 10-12 minutes. The microwave is convenient, but it softens the pastry and removes the flakiness.
