1. Crank your oven to 375°F and position the rack in the lower third. Butter a soufflé dish really well, then dust it with flour and tap out the excess—this helps your soufflé climb up the sides dramatically.
2. In a medium saucepan over medium heat, melt the butter completely. Add the flour and cook, stirring constantly with a whisk, for about 2 minutes until it smells slightly nutty but isn’t browning. This is your roux.
3. Gradually whisk in the milk in three stages, whisking like crazy after each addition until smooth. Keep cooking and stirring until the mixture thickens enough to coat the back of a spoon, about 3-4 minutes. Remove from heat.
4. Stir in the grated cheese until it melts into a smooth, glossy sauce. Season generously with salt and pepper—taste it and adjust because this is your flavor base.
5. Beat the egg yolks one at a time into the warm cheese mixture, whisking well after each addition. The mixture should be smooth and golden. Set aside to cool slightly while you work on the egg whites.
6. In a completely clean, dry bowl, beat the egg whites with the cream of tartar using an electric mixer on high speed until stiff peaks form, about 3-4 minutes. You should be able to turn the bowl upside down without anything moving.
7. Gently fold about one-third of the egg whites into the cheese base to lighten it, then fold in the remaining whites carefully. Use a rubber spatula and cut down through the middle, sweep along the bottom, and up the side. Stop as soon as you can’t see white streaks—overmixing deflates everything.
8. Pour the mixture into your prepared soufflé dish and smooth the top gently. Run your thumb around the inside rim to create a small groove—this helps it rise evenly and create that classic “top hat” look.
9. Slide it into the preheated oven and bake for 25-30 minutes until puffed and golden brown on top. The center should jiggle slightly when you gently shake the dish. DO NOT open the oven door during baking—seriously, don’t do it.
10. Serve immediately while it’s still puffed and gorgeous. Soufflés wait for no one, so have everyone at the table before you open that oven door.

This cheese soufflé provides excellent protein and calcium from the eggs and cheese, making it a surprisingly nutritious choice for a special breakfast or brunch dish.

Notes:

• Use room temperature eggs—they separate easier and the whites whip up better.
• Your bowl and beaters for the egg whites must be completely clean and grease-free, or the whites won’t whip properly.
• Every oven has its own personality, so start checking at 25 minutes. The soufflé should be golden and puffed but still jiggle slightly in the center.
• Don’t overmix when folding in the egg whites. Some small streaks are fine—better undermixed than overmixed.
• Serve immediately! Soufflés deflate as they cool, so timing is everything.
• If you want a taller soufflé, use a smaller, deeper dish. A wider, shallower dish gives you more surface area for that crispy top.

Storage Tips:

Honestly, don’t try to store soufflé—it’s meant to be enjoyed immediately while hot and puffed. If you absolutely must save leftovers, they’ll keep in the fridge for a day, but reheating results in a sad, deflated egg dish that bears no resemblance to the original. You can prep the cheese base up to 2 hours ahead and leave it at room temperature, then beat and fold in the egg whites right before baking.

Serving Suggestions:

• With a Simple Green Salad: Dressed with lemon vinaigrette to cut through the richness of the soufflé.
• As a Brunch Main: Serve with crispy bacon and fresh fruit for a special weekend breakfast.
• For Dinner: Pair with roasted asparagus and crusty bread for an elegant French-inspired meal.
• With Soup: A small soufflé alongside French onion soup makes a classic bistro lunch.

Mix It Up (Recipe Variations):

Herb Cheese Soufflé: Add 2 tablespoons fresh chopped herbs (chives, tarragon, or parsley) to the cheese base before folding in the egg whites. Light and perfect for spring.

Spicy Soufflé: Use pepper jack cheese and add a pinch of cayenne pepper to the base. Great for brunch when you want something with a kick.

Three-Cheese Soufflé: Use a combination of 2 oz Gruyère, 1 oz Parmesan, and 1 oz sharp cheddar for complex, layered flavor that tastes seriously fancy.

Mushroom Soufflé: Fold 1/2 cup finely chopped sautéed mushrooms (squeeze out all moisture first) into the cheese base. Makes it feel more substantial and earthy.

What Makes This Recipe Special:

This cheese soufflé works because of the science behind whipped egg whites—when you beat air into the whites and bake them, the air bubbles expand from the oven’s heat, creating that dramatic rise. The cheese-enriched base provides structure and flavor while staying light enough to puff. This technique has been perfected in French kitchens since the 1700s, when innovative chefs discovered that properly beaten egg whites could create dishes that seemed to defy gravity. It’s a testament to how understanding basic cooking science can create something that looks and tastes like pure magic.
