Caramel Flan

Flan is a rich, sweet custard topped with caramel sauce. It looks fancy, but it’s actually quite simple to make.

One of the most popular Latin desserts, flan is a rich, sweet custard topped with caramel sauce. It’s made with a mixture of eggs, milk, sugar, vanilla, and other flavorings, and then baked gently in a water bath until it is set but still creamy. The custard is then inverted onto a plate, revealing a layer of saucy caramel on top. Flan is almost identical to the French custard dessert crème caramel; it’s also similar to crème brûlée, only it’s a bit denser and, instead of the brittle caramel top, the caramel is liquid.

Though it looks impressive, flan is actually quite simple to make. This classic version adapted from Cook’s Illustrated is my go-to recipe. It’s prepared in a loaf pan rather than a wide cake pan, so it’s easy to unmold without breaking—and since it’s made up to four days ahead of time, it’s a wonderful dessert for company.

“Restaurant quality flan without the fuss (and fear)…A definite keeper.”

What You’ll Need To Make Flan

ingredients for flan
  • Sugar: Forms the caramel sauce that coats the flan, adding a rich sweetness and glossy finish.
  • Eggs and Egg Yolks: Provide structure and richness to the custard, giving the flan its creamy texture.
  • Sweetened Condensed Milk and Evaporated Milk: Add creaminess and sweetness to the custard base, ensuring a decadent flavor.
  • Whole Milk: Contributes to the velvety texture of the flan, enhancing its richness without overwhelming the other flavors.
  • Vanilla Extract: Infuses the flan with a warm, aromatic flavor, complementing the richness of the custard.
  • Bourbon: Adds depth, complexity, and a subtle hint of warmth to the flan’s flavor profile.

Step-By-Step Instructions

Step 1: Make the Caramel

bringing sugar and water mixture to a boil

Stir the sugar and 1/4 cup water together in a medium saucepan until the sugar is completely moistened. Bring the mixture to a boil over medium-high heat, without stirring. Continue cooking until the mixture begins to turn golden.

Gently swirling the pan, continue to cook until sugar is a pale honey color.

Remove from the heat and swirl the pan until the sugar is a reddish-amber color and fragrant, 15 to 20 seconds.

Carefully swirl in 2 tablespoons of warm tap water until incorporated – be careful as the mixture will bubble and steam. The water helps thin the caramel, so it doesn’t all stick to the pan after the flan bakes in the oven.

Pour the caramel into 8½ x 4½-inch loaf pan and set aside. The caramel will harden in the pan.

Step 2: Make the Custard

Whisk together the eggs and egg yolks in large bowl.

Add the sweetened condensed milk, evaporated milk, whole milk, vanilla, Bourbon, and salt and whisk until incorporated.

Strain mixture through a fine-mesh strainer into a larger bowl. The strainer will catch little bits of egg that you don’t want in your flan.

Pour the strained custard into the loaf pan over the caramel. Cover the loaf pan tightly with aluminum foil.

Step 3: Bake

Place the loaf pan in the center of a 9×13-inch baking or roasting pan (preferably with high sides) to make a water bath. Place the nested pans in the oven; using a tea kettle or pitcher, pour hot water around the loaf pan until it reaches about halfway up the sides of the loaf pan. The purpose of the water bath is to moderate the heat and ensure that the mixture cooks evenly into a smooth and creamy custard. (Cheesecake uses the same technique.)

Bake for 75 to 90 minutes. Very carefully pull back the foil (there will be steam that has accumulated under it) to ensure the custard is set around the edges but still a bit jiggly in the center. The custard should not be completely set when it is removed from the oven; it will continue to cook as it cools. Remove the pans from the oven. Remove the foil and leave the flan in the water bath for about one hour to cool.

Step 4: Chill and Unmold the Flan

Remove the loaf pan from water bath, cover tightly with plastic wrap, and chill overnight or up to 4 days. To unmold the flan, carefully slide a knife around the edges of the pan.

Invert a platter with a raised rim on top of the flan and turn the pan and platter over. If it doesn’t release immediately, let it sit inverted for a minute and it should eventually slide out. Remove the loaf pan and, using a rubber spatula, scrape the residual caramel over the flan. You won’t be able to release all of it – that’s okay. Slice the flan and spoon the sauce over the individual servings. Serve with berries, if you like.

Frequently Asked Questions

What can I do with leftover egg whites after making the flan?

Good question! Some options are my macarons, chocolate chip meringue cookies, and coconut macaroons.

Can I make flan ahead?

Sure, it will last nicely in the fridge, loosely covered with plastic wrap, for up to 4 days.

Can you suggest a substitute for whole milk in flan?

If you don’t have whole milk, you can substitute 2% milk or half-and-half, but I don’t recommend skim milk.

Can I substitute the bourbon in the recipe?

Yep, the bourbon can be substituted based on preference. You can use another type of liquor like rum or brandy to add a different flavor profile. If you prefer not to use any alcohol, just increase the vanilla by 2 teaspoons.

Flan is a rich, sweet custard topped with caramel sauce. It looks fancy, but it’s actually quite simple to make.

Servings: 8-10
Prep Time: 20 Minutes
Cook Time: 1 Hour 30 Minutes
Total Time: 1 Hour 50 Minutes, plus an overnight chill in the refrigerator

Ingredients

  • ⅔ cup sugar
  • 2 large eggs plus 5 yolks
  • 1 (14-oz) can sweetened condensed milk
  • 1 (12-oz) can evaporated milk
  • ½ cup whole milk (half-and-half or 2% milk may be substituted but do not use skim milk)
  • 2 teaspoons vanilla extract
  • 1 tablespoon Bourbon (see note)
  • ½ teaspoon salt

Instructions

  1. (This recipe should be made at least one day before serving.) Adjust a rack to the middle position and preheat the oven to 300°F.
  2. Stir together the sugar and ¼ cup water in a small heavy saucepan until the sugar is completely moistened. Bring to boil over medium-high heat and cook, without stirring, until the mixture begins to turn golden. Gently swirling the pan, continue to cook until sugar is a honey color. Remove from the heat and swirl the pan until the sugar is reddish-amber and fragrant, 15 to 20 seconds. Carefully swirl in 2 tablespoons of warm tap water until incorporated – be careful as the mixture will bubble and steam. This whole process should take less than 10 minutes.
  3. Pour the caramel into an 8½ x 4½-inch loaf pan; do not scrape out the saucepan. (Note: The caramel will solidify when you pour it into the loaf pan. That's ok -- it will soften up again as it bakes.) Set the loaf pan aside. (To clean the hardened caramel from the saucepan, fill the pan with water and bring it to a boil.)
  4. Whisk the eggs and yolks in large bowl until combined. Add the sweetened condensed milk, evaporated milk, whole milk, vanilla, Bourbon, and salt and whisk until incorporated. Strain the mixture through a fine-mesh strainer into a large bowl to remove any bits of egg; then pour the strained custard into the loaf pan over the caramel. Cover the loaf pan tightly with aluminum foil.
  5. Place the loaf pan in the center of a 9x13-inch baking or roasting pan (preferably with high sides) to make a water bath. Place the nested pans in the oven; then, using a tea kettle or pitcher, pour hot water around the loaf pan until it reaches about halfway up the sides of the loaf pan. Bake for 75 to 90 minutes. Very carefully pull back the foil (there will be steam that has accumulated under it) to ensure the custard is set around the edges but still a bit jiggly in the center. (Don’t worry that it seems undercooked. The custard will continue to cook as it cools, and the center will set completely -- I promise!) Carefully remove the pans from the oven. Remove the foil and leave the flan in the water bath for 1 hour to cool.
  6. Remove the loaf pan from the water bath and wipe the pan dry. Cover tightly with plastic wrap and chill in the fridge overnight or up to 4 days.
  7. To unmold the flan, carefully slide a sharp knife around the edges of the pan. Invert a platter with a raised rim (to contain the liquid caramel) on top of the flan and turn the pan and platter over. If the flan doesn’t release immediately, let it sit inverted for a minute and it should slide out. If it still doesn't come out, try running the knife around the edges again. When the flan is released, remove the loaf pan. Using rubber spatula, scrape the residual caramel onto the platter. You won’t be able to release all of the caramel – that’s okay. Slice the flan and spoon the sauce over individual portions. (Leftover flan may be covered loosely with plastic wrap and refrigerated for up to 4 days.)

  • This flan was AMAZING!!! So silky smooth, the perfect amount of sweetness. And it was so easy! I even said “that can’t be the whole recipe” but it was perfect. Thank you for sharing!

  • Hi and sorry to bother
    I’m always confused as to what kind of salt to use . I use kosher for most everything and table for salting cooking water but for flan I’m just not sure?? TYIA
    I love your recipes

    • Hi C D, So glad you like the recipes and not a bother at all! When a recipe of mine says salt in the ingredient list, I am referring to regular/table salt. I will specify in the recipe if it calls for something else, like kosher salt. Hope you enjoy the flan. 😊

  • Perfect recipe for someone making flan for the 1st time. I used half&half instead of whole milk, no bourbon, and doubled the vanilla. I was able to serve the flan the same after allowing 6 hours in the fridge

  • Jenn’s flan recipe is easily the best dessert in the whole world! I’ve made this flan countless times now – and each time that a friend, colleague or neighbor tries it for the first time, the same sentence comes out of their mouths, “Wow. I think this is the best dessert I’ve EVER had.” Lawyers, businessmen, doctors, surgeons, salesmen, and retirees alike all utter this sentence! I use Woodford Reserve bourbon. I also think that it is the easiest to make for a non-cook and non-baker like me! Was reading some previous comments and just want to add that one needs to follow the recipe to a T as Jenn does not waste words.. Important to make sure the flan is still jiggly when it comes out. Jenn is a goddess! She really makes us all shine. 😀

  • Wanted to say a big THANK YOU for this recipe- I made this for my buddy’s birthday (he loves flan) and he said it was straight up the best flan he’s ever had!

    I did make a few personalized modifications- I used Kavalan Taiwanese “Scotch” instead of Bourbon, and Honwakatou Sugar (Okinawa light brown sugar) for the caramel, and added a dash of paprika and cinnamon. It turned out absolutely marvelous. So thrilled that it worked out, thank you again!

  • I’m going to use a Mexican flan pan – looks like half a donut. How long do you think it will take to bake? I’ve used this pan before but have lost that recipe. This feels familiar. Am baking day before Super Bowl. Thank you.

    • Hi Martha, I wish I could help but really don’t know how long the baking time will be; I’d just keep a really close eye on it — sorry I can’t be more helpful!

  • Hi. I left the flan in the refrigerator overnight, almost 18 hours to solidify. However, when I flipped it out, it collapsed. This is the second time I made it and same issue. What do you think the issue is? Thanks.

    • That sounds so disappointing! I’m sorry you had a problem with it – did you happen to make any adjustments to the recipe? Are you confident you used sweetened condensed milk and evaporated milk?

    • Hi Rebecca – I’ve had this issue with flan before, and it turned out I had forgotten to boil the kettle before using it to add water to the bain marie. Did you pour *boiling* water between the dishes, or room temp figuring the oven would heat it up?

  • Hello Jenn,
    I wanted to know if I can divide this recipe into 2- 6″ pans
    Also do you think I can steam it in an instant pot.

    • Sure, two 6-inch pans should work. Just keep in mind that the baking time will be different. And I don’t have any experience with an instant pot, so I can’t say for sure whether or not you could cook this in one – sorry!

  • Hey Jenn-
    I’ve been making your Flan recipe for years and always gets rave reviews-Thank you for that.
    Question- Curious….Can this be frozen? Freeze right in the pan it was made in?
    (5 Stars!)

    • Hi Susie, So glad you like it! Unfortunately, I don’t think it’s a great candidate for freezing though – sorry!
