What is Flan Pâtissier?
Also known as Parisian Flan or French Custard Tart, Flan Pâtissier has been enjoyed for centuries in France. Unlike crème brûlée or other custards, this tart is baked in pastry, giving it a firm yet creamy texture and a caramelized top.
It’s the kind of dessert you’ll see sliced into generous wedges in boulangeries, ready to grab with a morning coffee or afternoon tea.
Ingredients
Pie crust
- 250g of all-purpose flour
- 125g of butter
- 83g of liquid (1 egg + water)
Custard
- 600g of milk

Step by Step Instructions
Prepare the Pastry
Follow your tested pastry dough method (you can also use our 5-minute foolproof pie crust recipe for guidance). Line a tart tin, chill it, and blind bake until lightly golden.
Make the Custard Filling
Heat the milk with vanilla to infuse it with flavor. In a separate bowl, whisk together the sugar, eggs, and cornstarch until smooth. Slowly add the warm milk, whisking constantly, then return the mixture to the pan and cook until it thickens into a luscious custard.
Fill and Bake
Pour the custard into the pre-baked pastry shell. Smooth the top and bake until the custard is set and the surface is beautifully caramelized.
Cool and Serve
Let the tart cool completely before slicing. This allows the custard to fully set for clean, bakery-style slices.
Serving Suggestions
- Serve chilled or at room temperature with a dusting of powdered sugar.
- Pair with fresh berries or a dollop of whipped cream for a seasonal twist.
- Perfect for brunches, afternoon tea, or as a stunning dessert for dinner parties.
Storage
- Refrigerate leftovers in an airtight container for up to 3 days.
