Classic Cheese Soufflé
- Cream of tartar helps prevent the whites from being accidentally overbeaten.
- Optionally whisking by hand gives you more control over your results (yes, it takes some elbow grease, but it's not that hard).
- Greasing the baking dish and dusting it with grated cheese creates a beautifully browned crust all-around.
- 3 tablespoons unsalted butter, plus more for greasing the dish
- Grated Parmigiano-Reggiano or Grana Padano cheese, for dusting the dish
- 3 1/2 tablespoons all-purpose flour
- 1 cup whole milk
- Kosher salt and freshly ground black pepper
- 1 teaspoon Dijon mustard (optional)
- 1 pinch cayenne pepper or two dashes hot sauce (optional)
- 4 large egg yolks
- 5 large cold egg whites
- 1/2 teaspoon cream of tartar (optional)
- 3 ounces freshly grated Gruyère or other semifirm cheese, such as cheddar
1. Preheat oven to 400°F (200°C) for a more browned soufflé with a slightly looser center or 375°F (190°C) for a more gently cooked soufflé that sets all the way through. Set oven rack in lowest position. Grease interior of 48-ounce ramekin with softened butter. Add some grated Parmigiano-Reggiano, rotating ramekin all around so cheese sticks to every part of buttered surface; add more cheese if you don't have enough or discard any excess. Wipe rim of soufflé dish and transfer prepared ramekin to the refrigerator until ready to use.
2. In a small saucepan, melt 3 tablespoons butter over medium-high heat (do not allow it to brown). Add flour and whisk to form paste. Continue to cook, stirring, until raw flour scent is gone, about 1 minute. Whisking constantly, add milk in thin, steady stream, or in increments of a couple of tablespoons at a time, whisking thoroughly and getting into all corners of pan to maintain lump-free texture. Sauce will initially become very thick, then get thin once all the milk is added.
3. Heat, stirring, until sauce comes to simmer and begins to thicken slightly. Reduce heat to low and cook, stirring and scraping the sides and bottom of pan, until sauce is nicely thickened, about 3 minutes. Season generously with salt and pepper. Transfer béchamel sauce to large heatproof mixing bowl and allow to cool slightly.
4. Whisk Dijon mustard and/or cayenne/hot sauce (if using) into béchamel. Then, while whisking constantly, work in egg yolks one at a time until thoroughly blended. Set soufflé base aside.
5. In large mixing bowl, using a French whisk, electric hand blender, or stand mixer fitted with whisk attachment, combine egg whites with cream of tartar (if using) and beat until firm, glossy peaks form.
6. Add 1/3 of beaten egg whites to béchamel base and stir well until whites are thoroughly combined and soufflé base has a looser consistency. Mix in Gruyère and then add remaining beaten whites. Using a silicon spatula, gently fold them into soufflé base just until well combined.
7. Remove soufflé dish from refrigerator and set on rimmed baking sheet. Scrape soufflé batter into prepared baking dish, filling it up to the inner ridge, not to the top (discard any excess). If desired, using an offset or other spatula, gently smooth and level surface of the soufflé batter.
8. Transfer soufflé to oven and bake until well risen and very nicely browned on top, about 30 minutes at 400°F for less set and 35 minute at 400°F for more set, and 35-40 minutes at 375°F for fully set.
9. Immediately transfer soufflé to table and serve before it deflates too much.
