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.”

  • 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

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.)

  • I made this recipe in my new Caraway non stick load pan.. it slid out beautifully. I didn’t read the recipe fully before I made it and did not have 24 hours to let it chill. It cooled in the fridge for about 4 hours and it was still delicious. It will probably be even better tomorrow evening. I love this website – every recipe is a hit. Thank you!!

  • 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.

  • This recipe…… was outstanding.!!!! I’ve always been nervous about making Flan and so for my first attempt, I thought of Once upon a Chef as Jen’s recipes never fail. Well, she came through again. – the savages (I mean the family) devoured this literally in one day!!
    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!

  • Whew!! I was glad someone asked the oven temp! I read the recipe all the way through 3 times thinking I overlooked it! Might want to add that as it is very low temp.
    Thanks for the person who asked.
