Herbed Potato Souffle - cooking recipe

Ingredients

2 tablespoons unsalted butter, plus more for brushing
1 1/2 lbs baking potatoes, peeled and quartered
3/4 cup half-and-half
1/2 lb gruyere cheese (2 cups) or 1/2 lb cantal cheese, shredded (2 cups)
1 teaspoon minced oregano
1 teaspoon minced thyme
1 tablespoon minced parsley
salt & freshly ground black pepper
5 large eggs, separated
2 large egg whites
1 pinch cream of tartar

Preparation

Preheat the oven to 375\u00b0.
Butter and flour a 2-quart souffle dish.
In a medium saucepan, cover the potatoes with cold water and bring to a boil. Simmer until tender, about 20 minutes.
Drain the potatoes and return them to the saucepan.
Shake the pan over high heat to dry out the potatoes, about 1 minute.
Add the 2 tablespoons of butter and mash the potatoes.
Stir in the half-and-half and let the potatoes cool slightly.
Stir in the cheese and the herbs and season with salt and pepper.
Stir in the 5 egg yolks.
Transfer the potato mixture to a large bowl.
In another large bowl, beat the 7 egg whites until foamy.
Add the cream of tartar and beat until stiff peaks form.
Stir one-third of the beaten whites into the potato mixture.
Using a rubber spatula, fold in the remaining whites until no streaks of white remain.
Scrape the mixture into the prepared souffle dish and bake in the bottom third of the oven for about 45 minutes, until the souffle is puffed and richly browned.
Serve immediately.
