Flan is a creamy caramel custard baked gently in a water bath, chilled and turned onto a plate so its caramel becomes a glossy sauce. This Latin American version uses condensed and evaporated milk for a rich, make-ahead dessert.
Flan at a Glance
What Is Flan?
The texture sits somewhere between a firm pudding and a soft cheesecake: it holds a clean slice but melts the moment it hits your tongue. The flavor is milky and vanilla-sweet, and the caramel adds a toasty, slightly bitter edge that keeps the whole thing from tasting cloying.
There are two main styles. Spanish flan (flan de huevo or flan casero) is made with fresh milk, eggs and sugar, and it is lighter and more delicate. Latin American flan, the version most people in the US know, swaps some or all of the fresh milk for sweetened condensed and evaporated milk, which makes it denser, creamier and more foolproof. The recipe below is the Latin American style.
One thing to know if you search in English: in the UK, a “flan” is an open tart with a pastry or sponge base, a completely different dessert. If you want the full breakdown of flan vs. crème caramel vs. pudim, read what’s the difference between pudim, flan and crème caramel.
Flan Ingredients (and What Each One Does)
Classic Latin flan needs just five ingredients plus a pinch of salt. Here’s what each one contributes, so you know what you can and can’t swap.
For one 8- or 9-inch flan · 10 slices
Equipment: an 8- or 9-inch round cake pan at least 2 inches deep, or a traditional lidded flanera (flan mold); a larger roasting pan for the water bath; a blender; and a fine-mesh sieve. An instant-read thermometer is optional but takes the guesswork out of doneness. Look for sweetened condensed milk and Mexican vanilla in the Latin aisle or online.
How to Make Flan, Step by Step
Here’s the method in brief, with the photos that matter most. The full recipe with exact amounts and times is in the recipe card below.
- Make the caramel. Cook the sugar with a splash of water over medium heat, swirling (not stirring) until it turns deep amber, like maple syrup. This takes 8 to 10 minutes, and the last 30 seconds go fast.
- Coat the mold. Pour the hot caramel straight into your pan and tilt it to cover the bottom. It will harden and may crackle as it cools. That’s normal; it melts back into sauce in the oven.
- Blend the custard on low. Condensed milk, evaporated milk, eggs, vanilla and salt go into the blender for 15 to 20 seconds, just until smooth. More blending means more air bubbles.
- Rest, strain and skim. Let the custard sit 5 minutes, pour it through a fine sieve and spoon off the foam. This is the step that gives you a glass-smooth flan with no holes.
- Bake in a water bath. Pour the custard over the caramel, cover with foil, set the pan in a roasting pan and add hot water halfway up the sides. Bake at 350°F until the edges are set but the center still wobbles.
- Chill, then flip. Cool for 30 minutes in the water bath and about 30 minutes on a rack, refrigerate within 2 hours of baking, chill at least 6 hours, run a knife around the edge and invert onto a rimmed plate in one quick motion.
How to Tell When Flan Is Done
Underbaked flan collapses when you flip it; overbaked flan turns rubbery and pitted. Use one of these three tests, starting at 45 minutes:
- The wobble test. Nudge the pan. The outer edge should be set and the center 2 to 3 inches should jiggle like gelatin, not ripple like liquid.
- The thermometer test. The center reads 170 to 175°F (77 to 80°C). Pull it here; carryover heat finishes the job.
- The knife test. A thin knife inserted halfway between the edge and the center comes out clean. (It will leave a small mark, which the caramel hides.)
Classic Flan Recipe
This is the Latin American condensed-milk flan: creamy, dense, sweet and very forgiving. Make it the day before you want to serve it.
Classic Caramel Flan
Silky, bubble-free Latin-style flan made with sweetened condensed milk, evaporated milk, eggs and vanilla under a deep amber caramel. The custard is mixed in a blender, baked gently in a water bath and chilled overnight.
Ingredients
Caramel
- ¾ cup (150 g) granulated sugar
- 3 tablespoons water
Custard
- 1 can (14 oz / 397 g) sweetened condensed milk
- 1 can (12 oz / 354 ml) evaporated milk
- 5 large eggs, at room temperature
- 1 tablespoon pure vanilla extract
- ⅛ teaspoon fine salt
Instructions
- Get set up. Heat the oven to 350°F (175°C) with a rack in the middle. Set an 8- or 9-inch round cake pan (at least 2 inches deep) or a 1½-quart flanera inside a larger roasting pan. Put a kettle of water on to boil.
- Make the caramel. Put the sugar and water in a small, light-colored saucepan over medium heat. Swirl the pan (don't stir) until the sugar dissolves, then let it bubble, swirling now and then, until it turns a deep amber, like maple syrup, 8 to 10 minutes.
- Coat the pan. Immediately pour the caramel into the cake pan and tilt it so the caramel covers the bottom and about ½ inch up the sides. Set it aside. The caramel will harden and may crackle; that's normal and it will melt back into sauce in the oven.
- Blend the custard. Add the condensed milk, evaporated milk, eggs, vanilla and salt to a blender. Blend on low for 15 to 20 seconds, just until smooth. Let it stand 5 minutes, then pour it through a fine-mesh sieve into a pitcher and skim off any foam.
- Fill and cover. Pour the custard over the hardened caramel. Cover the pan tightly with foil.
- Add the water bath. Set the roasting pan on the oven rack and carefully pour in hot water until it comes halfway up the sides of the flan pan.
- Bake. Bake 50 to 65 minutes, until the edges are set and the center 2 to 3 inches still wobble like gelatin when you nudge the pan. An instant-read thermometer in the center should read 170 to 175°F (77 to 80°C). Start checking at 45 minutes; a 9-inch pan bakes faster than an 8-inch pan.
- Cool and chill. Leave the flan in the water bath for 30 minutes, then lift it out and cool on a rack for about 30 minutes more. Refrigerate within 2 hours of baking; chill at least 6 hours, preferably overnight.
- Unmold. Run a thin knife around the edge. Dip the bottom of the pan in hot water for 30 seconds. Set a rimmed serving plate upside down on top, hold both together and flip in one confident motion. Lift off the pan and let the caramel run over the flan. Slice and spoon the sauce over each piece.
Notes
Pan size: An 8-inch pan gives a taller flan and needs the longer bake time; a 9-inch pan gives a thinner flan that sets in about 45 to 55 minutes. For ramekins, divide the caramel and custard among 8 six-ounce ramekins and bake 30 to 35 minutes.
No bubbles: Blend on low, rest the custard, strain it and skim the foam. Too much heat (no water bath, or an oven running hot) is what turns flan spongy and full of holes.
Flan de queso (flan napolitano): Blend in 8 oz (225 g) softened cream cheese with the other custard ingredients and bake about 10 minutes longer.
Storage: Keep flan covered in the refrigerator with its caramel for up to 4 days. Freezing is not recommended; the custard weeps and turns grainy when thawed.
Flan Problems and How to Fix Them
Almost every flan failure comes down to heat. Here’s what went wrong and how to fix it next time.
| Problem | Why it happens | How to fix it |
|---|---|---|
| Bubbles or holes | Too much air whipped in, or the custard boiled because the oven was too hot | Blend on low, rest and strain the custard, skim the foam, always use a water bath |
| Rubbery or grainy | Overbaked; the eggs tightened and squeezed out liquid | Pull it while the center still wobbles, at 170 to 175°F |
| Didn’t set | Underbaked, too few eggs, or not chilled long enough | Bake until the edges are firm, and chill a full 6 hours or overnight |
| Cracked top | Oven too hot or pan not covered | Cover with foil, use the water bath, and let it cool slowly in the bath |
| Bitter taste | The caramel went past amber to dark brown | Take the sugar off the heat the moment it looks like maple syrup |
| Caramel stuck in the pan | Flan too cold, or unmolded too soon | Dip the pan in hot water for 30 seconds before flipping; pour a little hot water into the empty pan to melt the rest into extra sauce |
| Caramel crystallized | Stirring, or sugar crystals on the pan sides | Swirl instead of stirring, and brush the sides down with a wet pastry brush |
| Liquid pooling around it | Weeping from overbaking, or it sat too long after unmolding | Bake a little less, and unmold just before serving |
Flan Around the Latin World
Every Spanish-speaking country has its own flan, and each tweak tells you something about the local pantry. Here’s how the main versions differ.
Beyond Latin America, the same dessert turns up as leche flan in the Philippines (steamed in oval llaneras, made with lots of yolks) and as purin in Japan. For the wider Latin family, including natillas, crema catalana and tocino de cielo, see our guide to Latin American and Spanish custards.
Flan Variations to Try
Once you’ve made the classic, the base recipe takes flavors easily. Change one thing at a time.
Blend 8 oz softened cream cheese into the custard and bake about 10 minutes longer. Denser and tangier, like a cross with cheesecake.
Swap the evaporated milk for a can of coconut milk and stir in ½ cup sweetened shredded coconut after blending. The coconut floats up and toasts.
Dissolve 2 teaspoons instant espresso in the vanilla before blending. Great with a darker caramel.
Blend in 1 cup pumpkin purée, 1 teaspoon cinnamon and a pinch of nutmeg. Bake 10 to 15 minutes longer.
Replace the condensed milk with dulce de leche for deep caramel flavor all the way through. Get the recipe.
Chocolate cake batter on the bottom, flan on top, and they switch places in the oven. Get the recipe.
Blend in ½ cup passion fruit pulp, mango or pineapple purée, and cut the evaporated milk by the same amount.
Warm 2 cups whole milk with a strip of lemon peel and a cinnamon stick, cool, then whisk with 4 eggs, 2 yolks and ½ cup sugar. Lighter and more delicate.
Other Ways to Cook Flan
- Individual ramekins: Divide the caramel and custard among 8 six-ounce ramekins, bake in a water bath at 350°F for 30 to 35 minutes, and unmold each one onto a small plate.
- Stovetop (steamed) flan: This is how many Cuban and Dominican families do it. Use a lidded flanera set on a rack in a large pot with 2 inches of simmering water, cover the pot and steam on low for 45 to 50 minutes, until the center wobbles.
- Instant Pot: Use a pressure-cooker flan recipe developed for your pan size and appliance. A short timing for individual ramekins does not apply to this whole flan; follow that recipe’s liquid, pressure-release and doneness instructions.
How to Serve and Store Flan
Serving: Flan is best cold, straight from the fridge, with the caramel spooned over each slice. Unmold it on a plate with a rim so the sauce doesn’t run off. It needs nothing else, but fresh berries, a little whipped cream or a small cup of cortadito are all traditional companions.
Make ahead: Flan is a perfect make-ahead dessert. Bake it up to 3 days ahead, keep it covered in its pan, and unmold it right before serving so the caramel looks glossy.
Storing: Keep leftovers covered in the refrigerator, sitting in their caramel, for up to 4 days. Because it’s made with eggs and dairy, don’t leave it at room temperature for more than 2 hours.
Freezing: You can freeze flan, but it’s not recommended. The custard weeps and turns grainy as it thaws.
A Short History of Flan
Custards of eggs, milk and honey go back to ancient Rome; the Roman cookbook attributed to Apicius includes one. The word itself comes from the Old French flaon, from the Late Latin flado, a flat cake. In medieval Europe a “flan” could be sweet or savory, filled with cheese, fish, spinach or almonds, and flans were especially popular during Lent.
Spain is where flan took the form we know: a sweet custard baked over caramelized sugar and turned out upside down. Spanish cooks carried it to the Americas and to the Philippines, where it became leche flan. In Latin America, canned sweetened condensed and evaporated milk became kitchen staples in the 20th century, and they turned flan into the creamier, denser dessert that most of the Americas makes today. Along the way each country put its own stamp on it, from Venezuela’s quesillo to Peru’s crema volteada.
Flan is still a celebration dessert. It’s on the table at Cuban and Puerto Rican Nochebuena dinners, at Puerto Rican Christmas, birthdays and Sunday lunches all over Latin America, and on the menu of nearly every Spanish restaurant.
Flan FAQs
What is flan made of?
Flan is made of eggs, milk and sugar. Latin American flan usually uses sweetened condensed milk and evaporated milk instead of fresh milk, plus vanilla. The sugar is cooked into caramel that lines the mold and becomes the sauce.
What’s the difference between flan and crème caramel?
They are essentially the same dessert: a baked custard over caramel, turned out to serve. Crème caramel is the French name and is usually made with fresh milk or cream, so it’s lighter. Latin American flan is usually made with condensed and evaporated milk, so it’s denser and sweeter.
What’s the difference between flan and pudding?
Pudding is cooked on the stove and thickened with starch. Flan is baked, set only by eggs, and served upside down with caramel. Flan is firmer and holds a clean slice.
Is flan Mexican or Spanish?
Both. Flan came to Mexico from Spain, and both countries treat it as a national dessert. The version made with condensed and evaporated milk is the Latin American one; the lighter fresh-milk version is Spanish.
Why does my flan have holes or bubbles?
Too much air or too much heat. Blend on low, let the custard rest, strain it, skim the foam, and always bake in a water bath at 350°F so the custard never boils.
Can I make flan without a water bath?
You can, but the edges overcook before the center sets, so you get a rubbery, pitted flan. The water bath keeps the custard below boiling. If you have no roasting pan, steam it on the stovetop instead.
How long does flan need to chill?
At least 6 hours, and overnight is better. Chilling finishes setting the custard and melts the caramel into sauce. Warm flan will fall apart when you flip it.
Can I make flan without condensed milk?
Yes. That’s Spanish-style flan: 2 cups whole milk, 4 eggs, 2 yolks and ½ cup sugar, flavored with lemon peel and cinnamon. It’s lighter and more delicate.
How long does flan last?
Up to 4 days covered in the refrigerator. Keep it with its caramel so it stays moist.
Is flan gluten-free?
Yes. Classic flan has no flour, so it’s naturally gluten-free. Check the labels on your vanilla and condensed milk if you’re cooking for someone with celiac disease.
