Traditional French Custard Tart
Cold butter, hot custard, and three vanilla beans — that is what separates a great flan pâtissier from a forgettable one. This traditional French bakery classic has a thick, just-set custard filling that wobbles slightly when you pull it from the oven and firms into dense, creamy slices once fully cooled. The shell is a tender almond short crust that holds its shape cleanly against the rich filling.
Give yourself a full afternoon. The dough needs a chill, the custard takes a steady hand at the stove, and the finished tart needs at least three hours before you cut into it. Patience is the one technique no recipe can replace here.
A traditional French custard tart built on a buttery almond crust and filled with a thick, vanilla-scented cream. The custard sets dense and smooth — nothing like the thin flans you may have had before. Slice it cold for the cleanest cut.

Method
- Beat the softened butter and powdered sugar together in a stand mixer fitted with the paddle attachment until the mixture is pale and creamy, about 2 minutes. Add the egg and mix until fully incorporated, then add the almond flour and all-purpose flour. Mix on low just until the dough comes together into a smooth ball — do not overwork it. Flatten into a disk, wrap in parchment, and refrigerate for at least 2 hours.9 tbsp unsalted butter, 3/4 cup powdered sugar, 1/4 cup almond flour, 2 cups all-purpose flour, 3/4 cup granulated sugar, 3/4 cup heavy cream, 7 tbsp salted butter
- Lightly butter a deep 8-inch (20 cm) tart ring. Remove the chilled dough from the refrigerator and roll it out between two sheets of parchment to a thickness of about ⅛ inch. Carefully lift and press it into the ring, trimming any excess flush with the top edge. Place the lined ring in the freezer while you prepare the custard filling.
- Preheat the oven to 330°F (165°C). Pour the milk into a medium saucepan and add half of the granulated sugar along with the scraped vanilla seeds and pods. Set over medium heat and bring to a simmer. Meanwhile, whisk the egg yolks with the remaining sugar in a large bowl until the mixture lightens in color, then whisk in the cornstarch until no lumps remain.1 large egg, 3 cups whole milk, 8 egg yolks, 7 tbsp cornstarch, 3 vanilla beans
- When the milk just reaches a boil, remove the vanilla pods and slowly ladle about one-third of the hot milk into the yolk mixture, whisking constantly to temper the eggs. Pour everything back into the saucepan over medium heat and stir continuously with a whisk until the custard thickens and begins to bubble, about 3 to 4 minutes. Remove from heat, then stir in the salted butter until melted and smooth, followed by the heavy cream. Whisk until the custard is completely homogeneous.
- Retrieve the frozen tart shell and immediately pour the hot custard into it, smoothing the top flat with an offset spatula. Slide the tart into the preheated oven and bake for 50 minutes, until the top is deeply golden and the center still has a slight wobble when you gently shake the pan. If the top colors too quickly, tent loosely with foil.
- Transfer the tart to a wire rack and let it cool to room temperature, then refrigerate for a minimum of 3 hours — overnight is even better. Run a thin knife around the inside of the ring before unmolding. Slice with a sharp knife rinsed under cold water between cuts for the cleanest edges. Serve cold straight from the refrigerator.

Notes
The custard must be poured into the frozen shell while it is still hot — this prevents the crust from going soggy before baking. Do not skip the 3-hour rest in the refrigerator; the filling needs that time to set fully before slicing.
