What is the Difference Between Crème Brûlée and Flan?

Silky smooth, sweet, rich custards are a sensual way to end a nice meal without being too heavy. Dessert custards all share something in common: a glossy, silken texture and lavish flavor. The difference between crème brûlée and flan (two of our favorite kinds of custard) lies in four factors: the ratio of ingredients, the manner in which the custard is thickened, the method of cooking, and any additional components. Those extra components — different toppings and presentation — are easiest to see.

THE BALANCE OF EGGS, SUGAR, AND DAIRY
In custards, the proportion of eggs to sugar to dairy is critical, since texture and flavor hang in delicate balance. Eggs lend sturdiness, and the most opulent custard desserts contain only egg yolks. Sugar also affects texture: The more sugar in a custard, the less firm it will tend to be, and the longer it will take to set. And the amount of fat in your dairy, whether cream or milk, will affect the dessert’s level of richness.

WHICH THICKENING AGENT?
Custard is set in one of three different ways: with eggs, starch, or gelatin. Crème brûlée, pots de crème, and flan are thickened with egg; in contrast, pastry cream and American-style cheesecake often employ cornstarch or flour. Gelatin is used to add a gel-like consistency to Bavarian cream and most mousse recipes.

COOKING AND SERVING METHOD
All custards are set using low, gentle heat. However, they fall into one of two categories: stirred (cooked on the stovetop) or baked (set in a water bath in the oven). Crème anglaise, pastry cream, mousse, and pudding are stirred; flan, crème brûlée, and pots de crème are baked. Custards can also be served at a wide range of temperatures: Serve crème anglaise warm, and it’s a sauce; freeze it and it becomes ice cream.

ADDITIONAL COMPONENTS
More elaborate custard desserts involve additional components, such as toppings or coatings. Crème brûlée contains a layer of hard caramel on top, achieved by melting sugar with a blowtorch; crème caramel is coated in a layer of soft caramel before being turned out.

When it comes to crème brûlée and flan, it's mostly the toppings that distinguishes the two, as well as the presentation. The former has that signature crackly sugar crust on top, and the latter has the gooey, soft caramel top. Crème brûlée is served within mini soufflé dishes, and flan is served out of the dish, standing alone. And it's also the culture each dessert hails from: French and Latin American cuisines.

Crème brûlée is a baked custard made with sugar and thickened with egg yolks and cream. It’s topped with sugar that’s torched or broiled to form a hard caramel crust. This basic crème brûlée just uses light and heavy creams, sugar, vanilla, and yolks. Get our Crème Brûlée recipe.
