How to Make French Custard Pie with Apples (Flan Parisien) Recipe
Step 1: Preheat and Prepare
Start by setting your oven to 325°F (170°C). This gentle temperature is perfect for slowly setting the custard without curdling, ensuring a silky smooth finish. While the oven warms, you can get your mixing bowls ready.
Step 2: Whisk the Custard Base
In a large bowl, whisk together your flour, salt, and granulated sugar until they’re well combined. Then add the eggs, whole milk, heavy cream, and vanilla extract. Whisk everything until your batter is perfectly smooth and glossy—this is the foundation of that luscious custard filling.
Step 3: Chill the Batter
Pop the batter into the refrigerator for at least one hour. This chilling step isn’t just about patience; it deepens the flavors and helps the custard set with the right texture when baked.
Step 4: Prepare the Pan and Apples
Line a 7.5-inch round cake pan with parchment paper to prevent sticking and make removal easier. Pour the chilled batter into the pan, then thoughtfully arrange the thin apple slices on top. The apples don’t just look beautiful—they’ll add a delicate fruity layer that contrasts wonderfully with the creamy custard.
Step 5: Bake to Perfection
Bake your custard pie for 45 to 50 minutes, keeping a close eye on it towards the end. You’ll know it’s done when a skewer poked into the center comes out clean, and the top has a slight golden hue that invites you to dig in.
Step 6: Cool and Serve
Allow the pie to cool for 15 to 20 minutes right in the pan; this lets it set fully and makes slicing easier. Then, using the parchment paper, gently lift the pie out. Serve it warm to enjoy the custard’s silky texture or refrigerate it until you’re ready for a cool, refreshing treat.
How to Serve French Custard Pie with Apples (Flan Parisien) Recipe

Garnishes
A dusting of powdered sugar is a simple yet elegant way to finish this pie, adding a snowy touch that feels festive and inviting. You might also sprinkle a pinch of cinnamon or nutmeg to enhance the warm apple notes without overpowering the delicate custard.
Side Dishes
Pair this pie with a lightly brewed cup of black tea or freshly brewed coffee to balance the richness. For a more indulgent experience, a scoop of vanilla bean ice cream or a dollop of lightly whipped cream makes for an absolute dream combination that’s sure to impress your guests.
Creative Ways to Present
Consider serving mini individual portions by baking the custard in small ramekins with apple slices on top. These personal pies look charming and make for a cozy dessert party. You can also drizzle a thin layer of caramel sauce or honey over the slices for an extra touch of decadence.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover any leftover pie tightly with plastic wrap or store it in an airtight container. The French Custard Pie with Apples (Flan Parisien) Recipe keeps beautifully in the fridge for up to three days, maintaining its delicate texture and fresh flavors.
Freezing
While freezing can slightly alter the texture of the custard, if you need to keep it longer, wrap slices in plastic wrap and place them inside a freezer-safe container. Thaw overnight in the refrigerator before serving, and reheat gently if desired.
Reheating
To enjoy the pie warm again, heat slices in a low oven at 300°F (150°C) for about 10 minutes. Avoid microwaving to preserve the custard’s silky texture and prevent it from turning rubbery.
FAQs
Can I use different types of apples for this pie?
Absolutely! Tart apples like Granny Smith provide a lovely contrast, while sweeter varieties such as Fuji or Honeycrisp add a milder apple flavor. Just slice them thinly for even baking.
Is it necessary to chill the batter before baking?
Yes, chilling allows the custard to firm up slightly and results in a smoother, creamier texture. Skipping this step may cause the custard to set unevenly during baking.
Can I make this pie gluten-free?
To make the French Custard Pie with Apples (Flan Parisien) Recipe gluten-free, simply substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup. The baking time and texture should remain similar.
What’s the best way to slice the pie?
Use a sharp, serrated knife for clean slices, especially since the custard can be delicate. Wiping the knife clean between cuts helps keep the slices neat and elegant.
Can I add other fruits besides apples?
Definitely! Pears or stone fruits like peaches and plums complement the custard beautifully. Just adjust the slicing and layering for even cooking.
