This No-Fail Cheese Soufflé Method Is Backed Up By Science

I was an exchange student in Belgium the first time I saw a tall, sizzling cheese soufflé being pulled from a home oven. It was airy and custardy on the inside, with a crisp cap that shattered under a spoon—an aerated, flavourful cloud that dissolved on the tongue, releasing the rich umami of sharp, buttery cheese. As much as the taste, it was the theatrics of the dish that pulled me in.

Although the spectacle of soufflé is restaurant-level to the max, it turns out this towering beauty requires only a simple blend of eggs, milk and cheese—along with a little preparation and attention to detail. First you build a thick, cheesy roux base, then you lighten it with whipped egg whites and finally you let steam and heat do the lifting. 

Most soufflé flops are caused by over-folding the batter (which pops the air bubbles you worked so hard to create) or over-beating the egg whites (if the whites become dry and grainy rather than glossy, the protein network loses its elasticity and can no longer stretch and hold the expanding steam). Here is what’s happening inside a soufflé—and how to get dependable results at home. 

What Makes A Soufflé Rise? 

Tiny bubbles of air in beaten egg whites expand when heated. As the mixture warms in the oven, water in the batter turns to steam and pushes against the protein network. Those proteins slowly set around the bubbles, giving the soufflé height while keeping the interior soft.

A béchamel sauce made from butter, flour and milk adds body, and cheese brings flavour and extra protein. Together, they support the egg whites so the soufflé holds its shape instead
of collapsing.

 How To Prep The Dish And Base 

Once the batter is mixed, you will want to bake it straight away, so preheat your oven and prep your dish before you get started. Generously butter the inside of the baking dish, then coat it with dry breadcrumbs. This rough surface gives the batter grip so it can climb up the sides as it bakes, which means a higher, more even rise.

Next, cook a simple béchamel sauce, letting it bubble until thick, which helps the soufflé stand tall. Remove it from the heat, stir in cheese and seasoning, then cool slightly before adding yolks.

Whipping And Folding 

Egg whites need an exceptionally clean bowl
and whisk or they won’t whip properly; just a spot of grease or fat can prevent the proteins from forming the bubbles you want. Start on medium speed until the whites look foamy, then increase speed until soft-peak stage. They should look glossy and smooth, with peaks that curve over when you lift the beater out.

To fold, first whisk a spoonful of whites into the base to loosen it. This keeps the rest from deflating as you combine the two. Then, using a wide spatula, scoop from the bottom and turn the mixture over itself until no streaks remain.

How To Bake A Cheese Soufflé 

Spoon the batter into your prepared dish, smooth over the top, then run your thumb around the inside rim, creating a little indentation. This channel helps the soufflé rise straight upward instead of catching and tearing on the edge. Bake on a lower oven rack so the top has room to rise without scorching. A soufflé will always sink a little once it leaves the oven, so plan to serve immediately.
