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.)

I made this flan and it was a huge success. I never made a flan before and I followed Jenn’s directions exactly as written. Guest were raving about it. One guest said he had tasted many flans in his time and this by far was the very BEST!! I appreciate all the details and hints that Jenn includes in her recipes.
So. I made it for the first time last night. Was nervous about the carmelized sugar but the video was terrific. My dilemma was that my loaf pan matching the size requirement is glass. I started out at the right temp but then thought I should lower the temp by 25 degrees because of the glass. I baked for 100 minutes. I had about 1/2” on the sides that firmed up. I took it out, cooled, and refrigerated overnight. This morning I have a very jiggly flan. I’m afraid it will just collapse if I try to remove it. This was a practice run so I’m going to bring it to room temp and put it back in the oven. Figure I have nothing to lose at this point. So. Should I have lowered the oven temp or should I have left it in longer? Thoughts? Thank you!
Hi Arlene, I’m glad you did a trial run! When you make this again, I’d recommend keeping the oven temp the same and keeping the flan in the oven until it is more done in the middle than you experienced your first time around. You may end up exceeding the baking time in the recipe as you did this past time. While it’s not mandatory for this recipe, if you continue to struggle with it, you may want to invest in a metal loaf pan. Good luck!!
Great recipe. Beautiful, delicate flavor and not too sweet.
Hi there,
I made this recipe, and it is currently in the oven. I’ve had it in there for around 75 minutes at 150 degrees celsius, however it is still very liquidy. I doubled the recipe, and as a result used a much larger and flatter pan for it, and also used only 5 whole eggs as that was all I had. Will all the changes I made affect it too greatly? I put it in for around 20 more minutes, but upped the temperature to 200 degrees celsius. If it doesn’t set at all, is there anyway to fix it, or is it going to be completely done for?
Thanks
Hi Aliza, unfortunately, it may be difficult to salvage. Because baking is such an exact science, I think the number of eggs you used definitely contributed to the problem. Sorry!
Hi there – my flan is not set perfectly. Can I still salvage it by cooking more in a water bath? If yes, how do you advise I do this?
Hi Melissa, Did you already unmold the flan?
Hi there,
I thought I responded earlier, but am re-posting in case it wasn’t successful.
No, I haven’t unmolded the flan. I am hoping to serve this on friday. What do you think? Do you think it might be worth a try to try another water bath ??
Thanks so much!
Melissa
Yes it’s fine to put it back in the oven in a water bath.
Hi Jenn, just a quick note to say that re-cooking in the water bath worked like a charm. It was delish, and I served with a raspberry puree. Thanks for your advice, and happy new year! Melissa
Omg this is so good. I made it last night for the first time and it was a hit with everyone in the household. It came out perfect amd the texture is soooo creamy!
I’ve made this recipe quite a few times and it’s delicious. I double the amount of vanilla and bourbon, just love the extra flavor.
The flan comes out without any holes (pet peeve of mine), just perfect. Thanks for sharing!
I love this recipe! It’s absolutely delicious. Can I make mini flans out of this instead of 1 flan in a loaf pan? I’m wondering if I can use 8 oz ramekins, and how many I should use. Thanks for the recipe!
Sure that will work but can’t say for sure how many – it depends on how high you fill them. Please LMK how it turns out if you try it. 🙂
New experience for me. I was a bit unsure of just how the caramel topping should look and act and threw the first attempt out – but no big loss. The second one seemed right. BUT one never knows until the final ‘unveiling’ of the dessert with the wide-eyed guests watching. At first I thought it was stuck, so just left it for a few moments and when I removed the pan it was PERFECT!!! A fabulous ending and everyone loved it. This was a perfect dinner with Jen’s beef enchiladas and the Mexican Rice. Rave reviews all around and all of it was made ahead of time and transported to my daughters to be re-heated and served. I love everything I make of Jen’s. And that is nearly all of my meals these days. From every day to special. THANKS!
If I want to make mine less sweet, do I simply put in less sweetened condensed milk? Like half or 3/4 of the can of sweetened condensed milk? Thank you.
Hi Jane, I’d stick with the amount of sweetened condensed milk but you could put less of the caramel mixture into the bottom of the loaf pan. Hope you enjoy!
I made this last night and will be having it for supper tonight for our family’s Thanksgiving get together. I just couldn’t get the caramel to change color. I started from stratch, but after 20 minutes had crystals. Found a youtube that demonstrated how to do it in the microwave and I had more luck with this. The rest went well, crossing fingers it inverts easy!
Hi Jen,
There was a comment from someone about lifting the foil to check for doneness. However, your recipe does not say to cover with foil before putting in the oven.
Thanks,
From another Jen
Hi Jen, You must’ve overlooked it, but it’s mentioned in the last sentence of the 4th paragraph. Hope that clarifies!
So to clarify, the directions are listed twice. Once with pictures and again at the bottom of this article. Only the bottom set of directions mentions foil. I noticed that after I had already started baking without the foil. Hope it turns out okay!
Hi Jesse, I’m sorry that the foil wasn’t mentioned in the step-by-step section – I’m going to update it now. I hope it came out okay!
