Prep: 45 min | Cook: 35 min | Total: 1 hr 35 min
Cost: $6.05 total, $1.01 per serving
Ingredients
- 6 pieces Egg Yolks (approx 100 g total, separated from whites)
- 100 g Caster Sugar (fine granulated sugar)
- 1 piece Vanilla Bean (split lengthwise and seeds scraped)
- 250 ml Heavy Whipping Cream (cold)
- 250 ml Whole Milk (cold)
- 50 g Corn Flour (for thickening (cornstarch))
- 20 g Unsalted Butter (for greasing the pan)
- 1 sheet Parchment Paper (cut to fit the baking dish)
- 1 sheet Plastic Wrap (to cover custard while cooling, contact method)
Instructions
Prepare the baking dish
Rub the inside of the 20 cm tart tin with a thin layer of softened butter. Line the bottom with a cut piece of parchment paper, allowing the paper to overhang the edges for easy removal.
Time: PT5M
Separate egg yolks
Crack the eggs and separate the yolks from the whites. Transfer the yolks to a clean mixing bowl; reserve the whites for another use (e.g., meringues).
Time: PT3M
Whisk yolks with sugar
Add the caster sugar to the yolks and whisk vigorously until the mixture becomes pale, thick, and slightly frothy (the "blanching" stage).
Time: PT5M
Incorporate corn flour
Sift the corn flour over the yolk‑sugar mixture and fold it in gently until fully incorporated, creating a smooth, thick batter.
Time: PT2M
Heat milk, cream and vanilla
In a saucepan, combine the whole milk, heavy cream, and the scraped vanilla seeds (plus the pod for extra flavor). Heat over medium‑high, stirring occasionally, until the mixture just comes to a boil.
Time: PT5M
Temperature: 150°C
Combine hot liquid with yolk mixture
Place a fine mesh sieve over the yolk‑flour bowl and slowly pour the hot milk‑cream mixture through, whisking continuously to prevent curdling. Once fully combined, return the mixture to the saucepan.
Time: PT3M
Cook the custard
Return the saucepan to medium heat. Whisk constantly until the custard thickens, comes to a gentle boil, and continues to boil for 4–5 minutes. It should coat the back of a spoon and have a glossy sheen.
Time: PT7M
Temperature: 150°C
Cool and cover
Transfer the hot custard to a clean container. Press a sheet of plastic wrap directly onto the surface to eliminate a skin. Let it rest at room temperature until cool (about 10 minutes).
Time: PT10M
Smooth the custard
Give the cooled custard a quick whisk to restore a creamy consistency.
Time: PT2M
Fill the prepared tin
Pour the custard into the butter‑greased, parchment‑lined tart tin. Smooth the top with a spatula.
Time: PT2M
Bake
Place the tin in a pre‑heated oven (300°F / 150°C, non‑fan‑forced). Bake for 30–45 minutes, or until the surface turns a light golden color and a thin crust forms.
Time: PT35M
Temperature: 150°C
Cool and serve
Remove the flan from the oven and let it rest on a wire rack until it reaches room temperature. Then refrigerate for at least 2 hours before slicing and serving.
Time: PT15M

Frequently Asked Questions
What is the cultural significance and history of Flan Pâtissier in French cuisine?
Flan pâtissier, also known as Parisian custard pie, is a classic French dessert that dates back to the 19th century. It was traditionally served in bakeries and homes as a simple yet elegant way to showcase high‑quality eggs, cream, and vanilla, embodying the French love for refined, buttery custards.
How does Flan Pâtissier fit into the broader tradition of French pastry?
Flan pâtissier is part of the French "pâtisserie" family, sitting alongside tarts, éclairs, and mille‑feuille. Its simplicity highlights the French principle that great flavor comes from a few premium ingredients, making it a staple in both everyday meals and festive occasions.
What traditional regional variations of Flan Pâtissier exist in France?
In Provence, a hint of orange blossom water is sometimes added; in the Loire Valley, a thin layer of almond frangipane may be placed beneath the custard. However, the classic Parisian version remains crustless and pure vanilla, as demonstrated in this recipe.
During which French celebrations is Flan Pâtissier traditionally served?
Flan pâtissier is commonly enjoyed at family gatherings, birthday parties, and as a light dessert after a hearty French dinner. It is also featured in pâtisserie shop windows during the summer months when fresh eggs and vanilla are abundant.
What authentic ingredients are essential for a traditional Flan Pâtissier?
The authentic recipe calls for fresh egg yolks, caster (fine) sugar, high‑fat heavy cream, whole milk, cornflour (or traditional wheat flour), and a real vanilla bean. Butter for greasing and parchment paper are optional but traditional for a smooth release.
What other French dishes pair well with Flan Pâtissier?
Flan pâtissier pairs beautifully with a cup of black coffee, a glass of sweet Sauternes, or a light fruit compote such as poached pears. It also complements savory French meals like coq au vin or ratatouille as a refreshing finish.
What are the most common mistakes to avoid when making Flan Pâtissier?
Common errors include over‑whisking the custard after it thickens (which can incorporate air), failing to cover the custard while it cools (causing a skin), and baking at too high a temperature, which burns the top before the interior sets.
Why does this recipe use corn flour instead of wheat flour for thickening?
Corn flour (cornstarch) provides a clear, glossy thickening without adding any wheat flavor, resulting in a smoother, more delicate custard that stays glossy after baking, which is traditional for the Parisian flan.
Can I make Flan Pâtissier ahead of time and how should I store it?
Yes, the custard can be prepared a day ahead. After baking, let it cool, then cover tightly with plastic wrap and refrigerate. It keeps well for up to three days and can be served chilled or gently warmed before serving.
