Ingredients
- 4 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 1.25 cups whole milk
- 1 cup sharp aged Gouda cheese, finely grated
- ½ cup Edam cheese, finely grated
- 5 whole large eggs, separated
- ½ teaspoon fine sea salt
- ¼ teaspoon freshly ground white pepper
- ⅛ teaspoon freshly grated nutmeg
Instructions
- 1
Preheat your oven to 375°F (190°C). Arrange an oven rack in the upper-middle position — this gives the soufflé room to rise without the bottom burning. Butter the inside of a 2-quart soufflé dish or round baking dish thoroughly, paying extra attention to the bottom and sides — this helps the soufflé climb evenly. Set aside.
- 2
Finely grate 1 cup of sharp aged Gouda and 0.5 cup of Edam cheese using a microplane or box grater. Set both cheeses aside separately to combine later.
- 3
Separate 5 large eggs, placing the yolks in a large bowl and the whites in a separate clean, completely grease-free bowl — even a tiny bit of yolk or oil will prevent the whites from whipping to stiff peaks.
- 4
Melt 4 tablespoons of unsalted butter in a medium saucepan over medium heat. Once foaming and fragrant, about 1 minute, whisk in 3 tablespoons of all-purpose flour to form a smooth paste. Continue whisking constantly for 2 minutes until the roux turns light golden and loses its raw flour smell — this cooks out the flour while keeping the roux pale, which preserves the delicate cheese flavor.
- 5
Slowly pour 1.25 cups of whole milk into the roux while whisking constantly to prevent lumps. Keep whisking for 3-4 minutes until the sauce thickens to the consistency of thick pudding and coats the back of a spoon — it should steam gently, not boil aggressively. You'll know it's ready when you draw a line with your finger on the spoon and it holds briefly.
- 6
Remove the pan from heat and stir in the 1 cup grated Gouda and 0.5 cup grated Edam until completely melted and smooth, about 1 minute of stirring. The residual heat will melt the cheese fully — don't return it to the heat or the cheese may separate.
- 7
Let the cheese sauce cool for 3-4 minutes, stirring occasionally. You want it warm but not so hot it scrambles the egg yolks when you add them. Test the temperature by dipping a clean finger in — it should feel like a warm bath.
- 8
Whisk the 5 egg yolks together briefly to break them up. Slowly add them to the cooled cheese sauce while whisking constantly — add about a quarter of the yolks first, whisking until fully incorporated, then add the rest in a slow stream. This tempers the yolks gradually and prevents curdling. Whisk until smooth and glossy, about 1 minute.
- 9
Season the cheese mixture with 0.5 teaspoon fine sea salt, 0.25 teaspoon freshly ground white pepper, and 0.125 teaspoon freshly grated nutmeg. White pepper keeps the soufflé a clean pale yellow, and the nutmeg adds a subtle warmth that complements Dutch cheeses beautifully. Taste and adjust seasoning — remember it will become more concentrated as the soufflé rises.
- 10
Using an electric mixer, beat the 5 egg whites on medium speed for 30-45 seconds until they turn foamy and opaque. Increase the speed to medium-high and continue beating for 2-3 minutes more until stiff, glossy peaks form — when you lift the beaters, the peaks should stand straight up with just a slight curve at the tip. Do not overbeat or the whites will separate and become grainy.
- 11
Gently fold about one-third of the beaten egg whites into the cheese mixture using a flexible silicone spatula. Use broad, sweeping strokes down the side of the bowl, across the bottom, and back up — don't stir or you'll deflate the whites. This lightens the base so it won't weigh down the remaining whites.
- 12
Gently fold the cheese-and-egg mixture back into the remaining egg whites using the same folding motion. Work quickly but carefully — stop when you see just a few white streaks remaining. Overmixing destroys the air bubbles that make the soufflé rise.
- 13
Scrape the entire soufflé batter into the prepared baking dish, smoothing the top gently with the spatula. The dish should be about three-quarters full — this gives the soufflé room to rise up and over the edges without spilling.
- 14
Place the soufflé on the upper-middle oven rack and bake for 25-30 minutes until the top is puffed and golden-brown and the edges are set. The center should still jiggle very slightly when you gently shake the dish — about a 1-inch circle in the middle should wobble. An instant-read thermometer inserted 1 inch from the edge should read 160°F (71°C). The carryover heat will continue cooking the center as you bring it to the table.
- 15
Remove the soufflé from the oven and place it immediately on the table — soufflés begin to deflate within 1-2 minutes of leaving the heat. Bring it to the table in the baking dish for dramatic presentation, or spoon portions directly onto warm plates. Serve immediately with a crisp green salad dressed with Dijon vinaigrette on the side.
