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

To make this flan, you’ll need three different types of milk: sweetened condensed milk, evaporated milk, and whole milk. If you don’t have whole milk, you can substitute 2% or half-and-half, but skim milk is not recommended. The splash of bourbon is my addition to the recipe – it adds incredible depth of flavor – but if you’d like to omit it, simply increase the vanilla by two teaspoons.

Since the recipe calls for 2 whole eggs and 5 egg yolks, you’ll have lots of leftover egg whites. If you’re looking for easy and delicious ways to use them up, check out my chocolate chip meringue cookies and coconut macaroons.

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.

Flan

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.)
  8. Note: If you would like to omit the Bourbon, replace with an additional 2 teaspoons of vanilla extract.

  • 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!

  • 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.

    • 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?

    • 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!

  • I’ve been making flan for my wife from new recipes for over 20 years, …and until this recipe never got an “A”. BUT this time I received an “A+++”. My wife, who’s an expert on the subject of flan, says this is the BEST flan she had in her 60 years.
    Instructions are GREAT.
    Thank you :-).

  • Hi Jenn,
    I would love to make this, but I’m a bit concerned about the caramel sauce crystallizing. It happens to me not infrequently, even when I follow the instructions very closely and use a nice sturdy All-Clad saucepan.

    I saw a recipe that has you add a little lemon juice to prevent this. I have made your microwave caramel sauce which includes a little lemon juice. Would you recommend this for the flan caramel sauce?

    • Hi Jane, I don’t recommend using lemon juice for the caramel. The key is to avoid stirring it while it’s cooking (gently swirl it, but don’t stir). Hope you have luck with it!

  • This is one of my go-to desserts for company – it is rich but not heavy, and a crowd pleaser.

    Just out of curiosity – what is the role of adding the water at the end of the caramel-making step? Most other flan recipes I’ve researched don’t require this step.

  • Made it the day before I had guests over for dinner. I followed your instructions to the letter. It came out perfect and was delicious. I will be making again. I am in Canada. I used the size of the 2 tins of milk we can buy here. The size of the tin of the condensed milk is a little smaller than what the recipe calls for. I did not add any extra milk to make up the size and it worked great.

  • Incredible taste and an amazing delight. It requires some conversion work for oz to ml for Canadian packaging and the two can sizes do not match the recipe. I used milk to make up the two volume differences and it was successful.

  • This Flan was the best I’ve ever eaten. I did substitute the whole milk with Mexican Table Cream, doubled the caramel sauce, and I pulled the flan from the oven in exactly 75 minutes. I served 8 people who raved about the Flan I topped with Chantilly Cream. With the leftover caramel sauce and Chantilly Cream, I added to my morning coffee and wished I had made two pans of Flan it’s so easy to make and simply wonderful.

    The only change I made was using 2% evaporated milk as that’s all I had on hand.
    It was so creamy and delicious that they requested I make it again….might have to make a separate one just for moi. :). Thank you for another outstanding recipe – you are amazing!
