How to Make Flan Pâtissier

  1. Infuse Milk: Heat 500ml of full-fat milk in a saucepan with the seeds scraped from 1-2 vanilla beans and 100g of caster sugar until just before boiling. Allow it to steep for 10 minutes to enhance the flavor.

  2. Prepare Egg Mixture: In a large bowl, whisk together 6 egg yolks, 1 whole egg, and 50g of caster sugar until creamy. Gradually blend in 30g of cornflour until smooth and free of lumps.

  3. Temper Eggs: Slowly add half of the hot milk mixture to the egg mixture while whisking vigorously. This prevents the eggs from cooking.

  4. Thicken Custard: Pour the egg mixture back into the saucepan with the remaining milk, and cook over medium heat, stirring constantly, until the custard thickens and bubbles appear, about 3-5 minutes.

  5. Finalize Custard: Remove from heat and stir in 50g of cold unsalted butter. Strain the custard through a sieve into a bowl, cover with plastic wrap to prevent a skin from forming, and let it cool. Refrigerate for at least 12 hours for the flavors to develop.

  6. Prepare Crust: Roll out the frozen butter puff pastry and cut it to fit the base and sides of a springform pan. Line the pan and place it in the freezer for 4-24 hours.

  7. Blind Bake: Preheat your oven to 220°C (430°F). Blind bake the crust with pie weights or dried beans for 25 minutes, remove the weights, and bake for an additional 5 minutes until golden.

  8. Assemble Tart: Once the crust is slightly cooled, lower the oven temperature to 200°C (390°F). Fill the crust with the cooled custard, leaving a 1 cm gap from the top. Brush the surface with an egg yolk for that lovely golden finish.

  9. Bake Tart: Bake for 65 minutes. Let the tart cool at room temperature for 4-5 hours, then refrigerate for at least 12 hours before serving to allow it to set perfectly.

Optional: Top with fresh berries or a light dusting of powdered sugar for a beautiful presentation.

Expert Tips for Flan Pâtissier

  • Measure Cornflour Accurately: Precision is key for a perfectly set custard. Too much or too little cornflour can affect the texture, leading to a runny filling.

  • Use High-Quality Vanilla: Opt for premium vanilla beans or extract to enhance the flavor of your Flan Pâtissier. The taste difference is significant!

  • Prevent Crumbling Crust: Ensure the butter puff pastry is kept cold while working with it. A warm pastry may lose its shape, making it difficult to handle.

  • Cool Gradually: After baking, let the tart cool at room temperature before refrigerating. This step prevents any unwanted moisture build-up that could affect texture.

  • Time for Flavor Development: Refrigerate the tart for at least 12 hours before serving. This resting period allows the flavors to meld beautifully and contributes to a delicious custard experience.

What to Serve with Flan Pâtissier?

Imagine the comforting warmth of your kitchen filling the air, perfectly completing each delightful bite of your French custard tart.

  • Fresh Berries: Juicy strawberries, blueberries, or raspberries add a burst of color and a tangy contrast to the rich custard. Their natural acidity cuts through the creaminess, creating a refreshing balance.

  • Powdered Sugar: A light dusting of this sweet treat enhances the tart’s presentation and adds a delicate sweetness that complements the custard without overwhelming it.

  • Espresso or Coffee: The robust flavors of a well-brewed coffee contrast beautifully with the sweet creaminess of the flan, making it an ideal accompaniment for a cozy dessert experience.

  • Whipped Cream: Fluffy, lightly sweetened whipped cream brings an airy texture that pairs pleasingly with the dense, silky custard. It’s like hugging your dessert!

  • Chocolate Sauce: A drizzle of rich chocolate sauce can add a delightful twist, elevating the dessert with luxurious flavors that create a sumptuous taste experience.

  • Citrus Zests: Garnishing with lemon or orange zest not only adds brightness but also introduces a fragrant note that refreshes your palate between bites.

Consider these delightful additions as you prepare to share your gorgeous Flan Pâtissier—it’s about creating a full sensory experience that will leave everyone asking for seconds!

What should I do if my custard doesn’t set properly?
If your custard isn’t setting, don’t worry! Revisit your cooking time. Ensure you’re boiling the mixture just until it thickens but not too long. If it’s still too runny after cooling, you can try reheating the mixture gently while whisking in 1-2 teaspoons of additional cornflour dissolved in a little milk until it thickens up, then strain and cool again.

Can I make Flan Pâtissier in advance?
Absolutely! In fact, I recommend preparing the custard and pastry crust a day ahead. This not only saves time but also allows the flavors to develop beautifully. Just store them separately in the fridge until you are ready to assemble and bake the tart.

Is Flan Pâtissier suitable for people with allergies?
This dessert contains eggs and dairy, so if you’re catering to someone with allergies, it may be best to look for alternative recipes or modifications. While I haven’t tried it myself, I’ve heard people have great success creating vegan versions using plant-based milks and egg substitutes like silken tofu.
