Ingredients

• 3 large sweet onions
• 3 tbsp unsalted butter
• 3 tbsp all-purpose flour
• 1.5 cups whole milk
• 0.5 cups Parmesan cheese, grated
• 0.75 cups Gruyère cheese, grated
• 4 large eggs, separated
• 1 tsp salt
• 0.5 tsp ground black pepper
• 0.25 tsp nutmeg, freshly grated

Directions

Step 1

Preheat your oven to 375°F (190°C). Butter a 1.5-quart soufflé dish and lightly dust the inside with grated Parmesan cheese. Set aside.

Step 2

Peel and thinly slice the sweet onions. In a large skillet, heat 2 tablespoons of butter over medium heat. Add the onions and cook slowly, stirring occasionally, until the onions are deeply caramelized, about 20 minutes. Remove from heat and set aside.

Step 3

In a medium saucepan, melt the remaining 1 tablespoon of butter over medium heat. Stir in the flour and cook for 1-2 minutes, stirring constantly, to make a roux.

Step 4

Gradually pour the milk into the roux, whisking constantly to prevent lumps. Cook the mixture for 3-4 minutes, until thickened and smooth. Remove from heat.

Step 5

Stir in the grated Gruyère cheese, half of the Parmesan cheese, salt, pepper, and nutmeg until fully melted and incorporated into the mixture. Let the béchamel sauce cool slightly.

Step 6

In a large mixing bowl, whisk the egg yolks lightly, then slowly stir in the cooled béchamel sauce. Fold in the caramelized onions gently.

Step 7

In a separate clean and dry mixing bowl, use an electric mixer to beat the egg whites until stiff peaks form.

Step 8

Using a spatula, gently fold one-third of the whipped egg whites into the onion mixture to lighten it. Then, carefully fold in the remaining egg whites, being cautious not to deflate the mixture.

Step 9

Pour the soufflé mixture into the prepared soufflé dish, filling it to about ¾ full. Place the dish on a baking sheet for stability.

Step 10

Bake in the preheated oven for 30-35 minutes, or until the soufflé has risen and the top is golden brown. Avoid opening the oven door during baking to prevent it from collapsing.

Step 11

Serve immediately and enjoy this light, fluffy, and flavorful Sweet Onion Soufflé!
