½ cup (about 2 ounces) sharp cheddar cheese, grated
¼ cup (about 1 ounce) Parmesan cheese, grated
1 teaspoon Dijon mustard
For the Ramekins (Preparation):
1 tablespoon butter, softened (for greasing)
2 tablespoons grated Parmesan cheese (for dusting)
Equipment Needed
Air Fryer (basket or oven style)

Whisk
Rubber spatula
Electric hand mixer or stand mixer (optional but highly recommended for the egg whites)
Step-by-Step Instructions
1. Prepare the Ramekins (Crucial for the Rise!)
The key to a magnificent rise is helping the soufflé “climb” the sides of the dish. Generously grease the inside of your ramekins with the softened butter. Use your fingers or a pastry brush to ensure the butter coats the bottom and all the way up to the rim. Next, add the 2 tablespoons of grated Parmesan cheese to one ramekin and tilt and rotate it so the cheese coats the buttered surface completely. Tap out any excess into the next ramekin. This cheese “crust” not only adds flavor but provides a grip for the soufflé to cling to as it rises, creating that iconic tall hat above the rim. Place the prepared ramekins on a plate and refrigerate them while you prepare the mixture. This helps the butter firm up.
2. Make the Cheese Sauce (Roux)
In a medium saucepan over medium heat, melt the 2 tablespoons of butter. Once melted and bubbling, add the flour and whisk constantly for about 1-2 minutes. You’re making a “roux.” Cook it until it is smooth and has a slightly nutty aroma, but do not let it brown. Slowly pour in the warm milk, a little at a time, while whisking vigorously to prevent lumps. Continue to whisk until the mixture is smooth and begins to thicken and bubble gently, about 2-3 minutes. This is your béchamel sauce base. Remove the saucepan from the heat. Stir in the salt, pepper, and nutmeg (if using), then add the Dijon mustard and both grated cheeses. Stir until the cheese is completely melted and the sauce is smooth and creamy.
3. Temper the Egg Yolks
This is a critical step to prevent your egg yolks from scrambling. Your cheese sauce is hot, and the yolks need to be brought up to temperature slowly. Add a generous spoonful of the hot cheese sauce to the bowl with the egg yolks and whisk vigorously until completely combined. Add another spoonful and whisk again. Now, slowly pour the tempered yolk mixture back into the saucepan with the remaining cheese sauce, whisking constantly. The mixture should be smooth, thick, and glossy. Set this base aside to cool slightly while you whip the egg whites. You want it to be warm, but not piping hot.
4. Whip the Egg Whites to Stiff Peaks
In a large, clean, and completely grease-free bowl, beat the egg whites with an electric mixer (or a whisk and a strong arm) on medium speed until they become foamy and opaque. Increase the speed to high and beat until stiff, glossy peaks form. The defining test is when you lift the beater out of the bowl, the egg whites should stand up straight and firm without flopping over. Do not over-beat, or the whites will become dry and grainy. This airy structure is the heart of your soufflé, so treat it with care.
5. Fold the Mixture (The Gentle Art)
Using a rubber spatula, take a large scoop of the stiff egg whites (about a quarter of the mixture) and vigorously stir it into your cheese sauce base. This “sacrificial” scoop is beaten in to loosen the dense sauce, making it easier to incorporate the rest of the whites. Now, gently but deliberately, add the remaining egg whites. Using a cutting motion, slice the spatula down through the center of the mixture, then scoop the bottom up and over the top. Rotate the bowl and repeat. This is “folding.” Be patient and gentle. You want to combine the mixture until no streaks of white remain, but it’s crucial to deflate as little of the precious air as possible. The final batter should be light, airy, and uniform.
6. Fill the Ramekins and Air Fry
Remove the prepared ramekins from the fridge. Gently spoon the soufflé batter into the prepared ramekins, filling them right to the rim. For the classic, dramatic “hat,” use the back of a knife or your finger to run a clean line around the inside edge of the ramekin, about ½ inch from the top. This helps the soufflé rise straight up and evenly. Place the ramekins in the air fryer basket. If your air fryer is smaller, you may need to cook them in batches, placing them in the center for the best heat circulation.
7. The Air Frying Process
Set your air fryer to 380°F (190°C) and cook for 12-15 minutes. The exact timing will depend on your specific air fryer model and the size of your ramekins. The soufflés are done when they are puffed, golden brown on top, and the centers are slightly jiggly. Do not open the air fryer during the first 10 minutes of cooking, as this can cause the soufflés to collapse from a sudden rush of cool air.
Time and Intensity Guide
Phase Estimated Time Intensity Level What to Look For
Preparation (Ramekins) 5 minutes Low Evenly greased and dusted ramekins.
Making the Roux 5-7 minutes Medium Smooth, thick sauce that coats the back of a spoon.
Whipping Egg Whites 3-5 minutes High Stiff, glossy peaks that hold their shape.
Folding 2-3 minutes Medium-High A light, uniform batter with no visible egg white streaks.
Air Frying 12-15 minutes Low (Hands-off) Puffed, golden brown tops with a slight jiggle in the center.

Total Time to Table ~40 minutes
Serving & Final Touches
The golden rule of a soufflé is: Serve immediately! They will begin to deflate as they cool. To serve, bring the hot ramekins to the table on a plate or a napkin-lined saucer. You can serve them directly in the ramekin or, for a more elegant presentation, gently loosen the edges with a butter knife and slide the soufflé onto a warm plate.
This airy, cheesy delight pairs beautifully with a simple green salad dressed in a light vinaigrette for a delightful lunch or light dinner. For brunch, serve alongside crispy bacon or smoked salmon.
Recipe Variations & Substitutions
Cheese Variations: Swap the cheddar for Gruyère, Gouda, Fontina, or a combination of your favorites for a different flavor profile.
Herb-Infused: Fold in 1-2 tablespoons of finely chopped fresh herbs like chives, thyme, or parsley along with the cheese.
Add Some Heat: A pinch of cayenne pepper or a dash of hot sauce added to the cheese sauce gives a wonderful kick.
Vegetable Additions: For a heartier version, fold in ½ cup of well-drained, finely chopped sautéed mushrooms, spinach, or sun-dried tomatoes.
