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.)

Hello. I am making this for company & I’m afraid one recipe will not be enough. Could I double the ingredients & divide between 2 loaf pans? Thanks
Sure!
Hi Jen, I have made this delicious flan a number of times and it always turned out perfect. Today I forgot to add the milk?. Remembered only after placing it in the fridge. It looked a little more jiggly than the times before. Do you think it will be ok without the milk or should I start over?
Hi Johara, I’m obviously weighing in too late to help, but I suspect it wouldn’t have impacted the flan that much. How did it turn out?
Hi Jen,
No worries, I did not want to risk it so made another one.? This first one was good but a little sweeter. ?
Thank you
I am super EXCITED to be making this. Prior to seeing your instructional video, I had convinced myself that I couldn’t possibly…
And now it’s in the oven— if this recipe is like any of your others that I’ve tried, I’m already happy, and so is my family! xo
I have made this before in a glass loaf pan and loved it but want to make it this time in metal as I need two flans. My bread pans are old from England in the 1960s! They make marvelous bread but I am worried that the flan might taste of metal. They are not rusty at all though. I am thinking of this in particular as I plan to make it 3 days before. Could I unmold them and store them in the fridge on a platter a couple of days in advance? Many thanks. I love your recipes and the videos!
Hi Barbara, so glad you like it! While technically, it’s doable to unmold and store the flans in the fridge for a few days, I’m not sure how you’d cover them without messing up the caramel layer. If you happen to have a large container with a lid, that would leave the caramel undisturbed, that would work.
Always a fan of your recipes Jen, but this one just didn’t do it for me. The flan was very eggy. Has great consistency and I like using the vanilla and bourbon. I’ll keep hunting for a favorite flan
Can I use a 9×5 pan? The pan I have is only 8×4 and when I put water in to test there was only a 1/2 inch head space left without the caramel or eggs.
Hi, I think a 9×5-in pan will work but the flan will be very short. For best results, I’d get an 8×4-in pan.
This was my first attempt making flan and it is a big success,delicious.Used the 9×5 it unmolded beautifully , it was a little flat and look for a better pan.Thanks for another great recipe,keep up the good work.
So glad it turned out well — thanks for taking the time to report back!
I’m Brazilian and this is a very common dessert. We call it pudim.
Our version is a little easier: blend 6 eggs, one can of condensed sweet milk, the same amount of milk and a teaspoon of vanilla extract (or more to taste). Blend it for a few seconds, just enough to mix it all together.
The caramel goes all around the insides of a pan, usually a Bundt (but it doesn’t really matter the shape).
The cooking is the same, although I never covered it.
Once it’s cooked, let it cool on a counter (no bath) and cover it with plastic film and refrigerate it for 4-6h at least, it can be more. I do overnight often. Then you remove it from the pan using the knife technique Jen showed.
Simple. Easy. Cheap. No leftover egg whites.
Probably not the exact same consistency but another version one could try
I like mine with air bubbles so I bake it straight in the oven and longer time. My husband likes it creamy so double bath it is for less time. You can play with it. It’s a very forgiving recipe.
I’ve done it with 4 eggs only, adding more yolks… it always turns out, each version slightly different, but always good.
This year we did Mexican Christmas dinner for our family gathering and I picked your flan recipe and made it. it was very easy to follow except I couldn’t find the temperature of the oven and then I read your comments and it was in there. Everybody loved the flan. Few people have had Flan before and said that that was the best that they’ve had. It was really the talk of the food.
thank you for your recipe
This is a wonderful dessert but can I use Whipping cream instead of the evaporated and condensed milk as a family member cannot drink milk but can have cream.
Is it possible for the nutritional values to also include potassium levels
Hi Rose Marie, I wouldn’t recommend whipping cream in place of the evaporated milk and condensed milk — I’m not confident it would come out right.
I’ve made it with dairy free sweetened condensed milk (coconut I think) and coconut milk and it turned out good. But it was my version of the recipe (see recipe on my comment above). I think as long as you use the condensed milk dairy free and the amount of liquid called for, using another dairy free milk, it *should* work. I have not tried it myself but I would if I had a dairy free guest.
Easy and delicious. I really enjoyed making and eating it. As good as any I’ve had. I omitted the bourbon and was skeptical about the additional vanilla but it was spot on.
