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
- 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
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
Good question! Some options are my macarons, chocolate chip meringue cookies, and coconut macaroons.
Sure, it will last nicely in the fridge, loosely covered with plastic wrap, for up to 4 days.
If you don’t have whole milk, you can substitute 2% milk or half-and-half, but I don’t recommend skim milk.
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
Flan is a rich, sweet custard topped with caramel sauce. It looks fancy, but it’s actually quite simple to make.
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
- (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.
- 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.
- 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.)
- 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.
- 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.
- 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.
- 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.)

Would the flan still stand ok if baked in a loaf pan with more rounded edges vs. the sharper edged loaf pan? Could this be baked in a 9 inch round pan (and I’m assuming adjust the bake time? Any estimates of what that bake time range in minutes would be?)
Hi Julie, either of those pans should be fine. If you go with the 9-inch round pan, the bake time may be slightly different but not sure by how much so keep a close eye on it. Hope you enjoy!
This is definitely one of the best flan recipes I’ve tried. It came out super custardy and really solidified well after resting. The suggestion to add a bit extra vanilla extract instead of brandy worked perfectly. Thank you for sharing!
Hi Jenn,
As is this was exceptional, like all your other recipes. I’m wondering if there is anyway I could adapt this recipe to make it lactose free — this is my bff’s favourite dessert but she recently developed lactose intolerance and Im trying to find away to make it for her 🙂
Thank you so much
So glad you liked it! This has so much dairy, that I don’t think it will translate well to a non-dairy version. Sorry!
This was AMAZING! I’ve served this a number of times and it leaves people moaning with pleasure. I omitted the bourbon and used the additional vanilla as the recipe suggests.
One word of caution, don’t start making this at 9pm at night if you’re early to bed. I had to bake it the full 90+ minutes (until almost set) and then the additional 1 hour cooling time in the water bath made it for a later than expected bed time. Well worth it. Enjoy.
Hello Jenn
First I would like to thank you for such tasty and yum recipe.
I made flan for the first time in my life yesterday and the result was perfect taste 🙂 but not so perfect texture 🙁
I did exactly as you advised – cooked for 90 mins at 300 F, let it sit in the pan for one hour after taking out from oven, and overnight in fridge.
But when i took it out today in the morning, the middle part was not set. It was more like pudding or thick soup but the sides were perfectly set and were holding their shape.
I am not sure where I went wrong 🙁
But the taste was heaven….
Please advise or suggest what I can do better next time to keep the shape and texture perfect as well.
Hi Manasi, Glad to hear you like this but sorry that it was a bit underbaked. Did you by any chance use a glass loaf pan? (Glass is better at conducting heat than metal and sometimes that will cause the outside/edges of a baked good to get browned/baked before the center is fully cooked.
Hi, can I bake this in a loaf pan made of stone?
Yes, I think that should work. Hope you enjoy!
This recipe used to be perfect. Just recently, they added the step of covering it with aluminum foil. I tried it with the foil to see what the difference would be…. Undercooked and runny. I tried putting it back in the oven for another 15 min uncovered, but it was ruined. I have no idea why they changed it when it was perfect to begin with. Try it without the aluminum foil and cook it at 300 for 75 min. It will come out perfect.
Hi , can I bake this on a Bundt Cake pan ? I have made on the regular pans and it cane our amazing!!!’
Hi Natalia, I wouldn’t use a bundt pan as I don’t think you’ll have enough custard to fill it (and it would be hard to run a knife along the edges to unmold it without butchering it). Sorry!
Thank you for replying ! Is it possible to double this recipe ? I need to make a big flan for a family gathering . This recipe is the best I ever tried .
So glad you like it! Yes, you cand double it. I’d just make it in 2 loaf pans (they may take just a tiny bit longer to cook). Enjoy!
Hi Natalia, I almost always make flan in my Bundt cake pan and always comes out perfect and have no issues with it. Give it a try!
Hello. Thank you for the recipe. It came out great. When I made the second time I did add one extra ingredient which was a piece of cream cheese because I wanted it to be a little firmer.
I do have one question – if I want to make other variations of flavors of the flan, such as coffee, or guava, or passion fruit – should I reduce some of the milk and replace with the coffee or passion fruit juice so that is it not too liquidy? If so, which of the two should I reduce – the evaporated milk or the whole milk or both?
Hi Yadira, glad this turned out nicely for you! I wouldn’t recommend fiddling with the recipe too much but if you wanted to give this a coffee flavor, you could add 1 to 2 teaspoons of espresso powder. You could try to experiment a bit beyond that but not sure how forgiving the recipe will be.
I followed this recipe almost exactly. I did not have any bourbon, so I added the extra vanilla instead. I only baked it for 65 minutes, and it turned out perfect. I have tried other flan recipes and this one is our favorite, so far… thanks
This was absolutely AMAZING!! The first time I made it, I surprised my entire family with it, and they were in love. Ever since it is the only flan recipe I like to use. It is creamy, and sweet, and just every part fantastic. Thanks for the perfect recipe!
Can I do this in an 8 inch round pan ? Thanks
Sure — the baking time may be slightly shorter so keep a close eye on it. Hope you enjoy!
