• 2 tbsp finely grated Parmesan (for coating the dish)

Soufflé base

• 3 tbsp (42 g) unsalted butter
• 3 tbsp (24 g) all-purpose flour
• 1 cup (240 ml) whole milk, warmed until steaming
• 1/2 tsp kosher salt
• 1/8 tsp ground white pepper (or fine black pepper)
• 1/4 tsp freshly grated nutmeg
• 1 tsp Dijon mustard (optional, but recommended)
• 1 1/2 cups (150 g) Gruyère, coarsely grated, divided (1 cup/100 g for base; 1/2 cup/50 g folded in later)
• 4 large egg yolks

Egg whites

• 5 large egg whites, at room temperature
• 1/4 tsp cream of tartar
• Pinch of kosher salt

Topping & garnish

• 2 tbsp (20 g) Gruyère, finely grated (for topping)
• Pinch of freshly grated nutmeg
• Finely snipped chives (optional)

Step-by-Step Instructions

Step 1: Prep the oven and dish

Place a rimmed baking sheet on the middle rack and heat the oven to 400°F (200°C). Generously butter a 1.5-quart (1.4 L) soufflé dish, then dust the entire interior with the grated Parmesan, tapping out the excess. This cheesy coating helps the soufflé climb. Optional: Wrap a parchment collar around the outside of the dish, extending 2 inches above the rim, and secure with kitchen twine for extra height and clean edges.

Step 2: Warm the milk

Gently heat the milk in a small saucepan or microwave until steaming but not boiling. Warm milk incorporates more smoothly into the roux and reduces lumps.

Step 3: Make the béchamel and melt in cheese

In a medium saucepan over medium heat, melt the 3 tbsp butter. Whisk in the flour and cook, whisking constantly, for 60 seconds to remove the raw taste. Slowly pour in the warm milk while whisking to create a smooth sauce. Continue cooking, whisking frequently, until thick enough to coat the back of a spoon, 2–3 minutes. Remove from heat and season with salt, white pepper, nutmeg, and Dijon if using.

Add 1 cup (100 g) of the Gruyère and whisk until fully melted and smooth. Let the mixture cool for 5 minutes so it’s warm but not hot (hot base can scramble the yolks).

Step 4: Enrich with yolks

Whisk in the egg yolks one at a time until fully incorporated and glossy. This is your stable, flavorful base. Transfer to a large mixing bowl to cool slightly while you whip the whites.

Step 5: Whip the egg whites to glossy peaks

In a clean, grease-free bowl, beat the egg whites with the cream of tartar and a pinch of salt. Start on medium speed until foamy, then increase to medium-high and beat to glossy medium peaks—when you lift the whisk, the tip should gently curl. Avoid overbeating to dry, clumpy peaks; you want supple, shiny whites for maximum lift.

Step 6: Fold and fill

Stir one-third of the whipped whites into the cheese base to lighten. Using a large spatula, gently fold in the remaining whites in two additions, along with the remaining 1/2 cup (50 g) Gruyère, just until no streaks remain. Do not overmix. Scrape the batter into the prepared dish, smooth the top, then run your thumb around the inside rim to create a shallow moat—this encourages a tall “top-hat” rise. Sprinkle the top with the 2 tbsp Gruyère.

Step 7: Bake and serve immediately

Set the soufflé dish on the preheated baking sheet and bake for 25–28 minutes, until risen 2 inches above the rim and deeply golden. Do not open the oven for the first 20 minutes. The center should gently wobble but not slosh. Remove, grate a whisper of nutmeg over the top, add chives if desired, and take it straight to the table. Soufflés wait for no one—serve at once.

Pro Tips

• Room-temperature eggs whip higher and fold more easily; separate them while cold, then let whites stand 20 minutes.
• Coarsely grate Gruyère by hand for better melt and taller rise; pre-shredded cheese often contains anti-caking agents.
• A preheated baking sheet provides strong bottom heat for an even, impressive lift.
• Running a thumb around the rim is a simple bakery trick for the classic top-hat look.
• Resist opening the oven before 20 minutes; sudden drafts can deflate the soufflé.

Variations

• Comté or Emmental Swap: Replace Gruyère with Comté or Emmental for a slightly sweeter, nutty profile.
• Herb & Spinach: Fold in 1/2 cup finely chopped blanched spinach (well-squeezed dry) and 1 tbsp chopped chives or parsley with the final addition of whites.
• Individual Ramekins: Bake in six 8-oz (240 ml) ramekins for 16–18 minutes at 400°F (200°C).

Storage & Make-Ahead

Soufflés are best served immediately and do not hold their height. You can make the base (through adding yolks and melting in the first portion of cheese) up to 24 hours ahead; press plastic wrap directly onto the surface and refrigerate. Before baking, let the base sit at room temperature 30 minutes and whisk briefly to loosen; then fold in freshly whipped whites and proceed. Leftovers will deflate but still taste wonderful: reheat portions at 350°F (175°C) for 8–10 minutes. For a “twice-baked” treat, chill leftovers until firm, unmold onto a buttered dish, spoon 2 tbsp heavy cream over each piece, sprinkle with a little cheese, and bake at 375°F (190°C) for 12–15 minutes until puffed and golden at the edges.
