This traditional flan recipe makes a smooth baked custard with a glossy caramel top and plenty of caramel sauce for serving. It’s made with eggs, sweetened condensed milk, evaporated milk, sugar, and vanilla, then baked gently in a water bath and chilled before unmolding.
I love how a short ingredient list turns into such an elegant dessert. If you’re planning a dessert table, pair it with my Mango Mousse, Fluffy Vanilla Cake, Protein No Bake Cheesecake, or 3-Ingredient Japanese Cheesecake.
What Is Flan?
Flan is a baked caramel custard. In this version, eggs are blended with sweetened condensed milk, evaporated milk, and vanilla, then poured over a layer of caramelized sugar.
The custard is baked in a water bath, which gives it gentler, more even heat. King Arthur’s flan guidance also recommends baking flan in a hot-water bath and removing it while the edges are set but the center still has a soft jiggle.

Ingredients
The ingredient list is short, so choose good vanilla and use full-fat canned milk for the creamiest result. Measure the sugar before starting because caramel moves quickly once it begins to turn amber.
Let’s Make Flan
Make the caramel
Set a 9-inch round cake pan nearby. Add the sugar to a small, heavy saucepan and place it over medium heat. Let the sugar melt without stirring; gently swirl the pan from time to time as the edges liquefy.
Once it turns a deep amber color, immediately pour it into the cake pan. Carefully tilt the pan so the caramel coats the base in an even layer. It will harden quickly, so work with caution and do not touch the hot sugar.
Blend the flan
Heat the oven to 350°F (175°C). Add the eggs, sweetened condensed milk, evaporated milk, and vanilla to a blender. Blend for 20 to 30 seconds, just until the mixture looks smooth.
Pour the flan gently over the hardened caramel. Place the cake pan inside a larger 9-by-13-inch baking dish or roasting pan.
Bake the flan in a water bath
Pour hot water into the larger dish until it reaches about halfway up the sides of the cake pan. Cover the cake pan loosely with foil, then carefully transfer the water bath to the oven.
Bake for 50 to 60 minutes, until the edges are set and the center still has a small, gentle wobble when the pan is moved. A thin knife inserted near the center should come out mostly clean.
Cool and unmold
Lift the cake pan out of the water bath and let it cool at room temperature for about 1 hour. Cover and refrigerate for at least 4 hours, although overnight gives the cleanest slices.
To serve, run a thin knife around the inside edge of the pan. Place a rimmed platter on top, then invert in one confident motion. Let it sit for a few seconds before lifting the pan so the caramel sauce can pour over the custard.
How to Get Smooth, Creamy Flan
The biggest thing is gentle heat.
The water bath surrounds the flan pan with hot water, helping the custard cook more evenly than direct oven heat alone.
Avoid over-blending the custard, too. Extra air can leave bubbles or a more porous surface.
And don’t wait for the center to become completely firm in the oven. The flan should still wobble gently when you remove it.
King Arthur’s flan troubleshooting guide similarly notes that overcooking can produce a firm, eggy custard with holes, while the ideal flan is removed when the edges are set and the center still jiggles.
Common Mistakes to Avoid
Burning the caramel: Stay close once the sugar starts changing color. Deep amber is good; very dark caramel can become bitter.
Stirring the melting sugar: Follow your tested dry-caramel method and gently swirl the pan instead.
Blending too long: Your tested 20–30 seconds is enough.
Skipping the water bath: The gentler heat is important for the custard texture.
Using boiling water: Use hot water rather than aggressively boiling water.
Overbaking: Remove the flan when the edges are set and the center still has a gentle wobble.
Unmolding too soon: Your flan needs at least 4 hours of chilling before you invert it.
Using a flat serving plate: A rimmed platter is better because it catches the caramel sauce.
What to Serve with Flan
Flan is rich enough to serve on its own, but a simple accompaniment works well.
Try:
- Fresh strawberries
- Raspberries
- Sliced oranges
- Fresh mint
- Whipped cream
- Coffee
- Espresso
I’d keep the toppings simple so the caramel remains the main flavor.
FAQs
Yes. In fact, it is better made ahead because it needs at least 4 hours in the refrigerator to set properly. Making it the night before gives you a firmer custard and makes serving much easier.
Store it tightly covered in the refrigerator and enjoy it within 3 to 4 days. Keep it cold and return leftovers to the fridge promptly after serving.
It is best not to. The caramel and custard can separate after thawing, which affects the texture and makes the slices weep.
Fresh berries, sliced oranges, or a little whipped cream all work nicely. For a simple dessert table, serve it alongside Easy Mango Mousse so guests can choose between two cool, creamy desserts.
Overbaking is the most common cause. Bake just until the center still jiggles slightly.
Caramel naturally hardens as it cools. During baking it melts again into the sauce.

Method
- Preheat the oven to 350°F (175°C). Place a 9-inch round cake pan nearby.
- Add the sugar to a small saucepan over medium heat. Allow it to melt, gently swirling the pan occasionally, until it becomes deep amber.
- Immediately pour the caramel into the cake pan. Carefully tilt the pan to coat the bottom, then set aside to harden.
- Add the eggs, sweetened condensed milk, evaporated milk, and vanilla to a blender. Blend for 20 to 30 seconds, just until smooth.
- Pour the custard mixture over the caramel in the cake pan.
- Place the cake pan inside a larger baking dish. Pour hot water into the larger dish until it reaches halfway up the sides of the cake pan.
- Cover the cake pan loosely with foil. Bake for 50 to 60 minutes, until the edges are set and the center has a light wobble.
- Remove the cake pan from the water bath. Cool for 1 hour, then cover and refrigerate for at least 4 hours or overnight.
- Run a thin knife around the edge of the pan. Invert onto a rimmed serving platter and let the caramel sauce flow over the custard.

Notes
- Do not use a springform pan because water can leak into the custard.
- Keep blending brief to avoid creating too many bubbles.
- The center should wobble slightly after baking. It will firm up completely as it chills.
- Use a platter with raised edges to catch the caramel sauce.
- Nutrition values are approximate and vary by ingredient brand.
