Katrina's Spinach and Kale Souffle

Spinach Souffle

1 tbsp grated asiago
6 cups packed spinach & kale leaves
4 ½ tbsp butter
2 tsp minced shallot
¼ cup quinoa gluten free flour
¼ tsp freshly grated nutmeg
1 cup whole milk
4 whole eggs, separated, plus 2 egg whites, at room temperature

Preheat oven to 375 f. Butter bottom and sides of a 1 quart soufflé dish. Sprinkle bottom with cheese, then turn dish on its side, tapping and turning to coat all sides with cheese, set aside.

In a large saucepan over high heat, bring 4 cups water to a boil. Add spinach, reduce heat to medium, and cook until spinach is wilted but still bright green, about 4 minutes. Remove to a colander and rinse under cold running water, and chop coarsely. In a frying pan over medium high heat, melt 1 tbsp butter. When it foams, add shallot and cook, stirring, until translucent, about 1 minute. Add spinach and cook, stirring, until it glistens, about 2 minutes. Set aside.

In a medium saucepan over medium high heat, melt 3 ½ tbsp butter. When it foams, remove from heat and whisk in flour, 1 tsp salt, and ¼ tsp pepper. Return to medium high heat and add milk slowly, whisking constantly. Cook, whisking occasionally, until taste of flour is gone and sauce is thickened and smooth, about 5 minutes. Remove from heat and let cool for 2 - 3 minutes.

In a bowl, using an electric mixer or a whisk, beat 6 egg whites until stiff peaks form when beater or whisk is lifted. In another bowl, beat 4 egg yolks until creamy.

Whisk egg yolks into cooled white sauce until well blended. Stir in spinach mixture. Stir about 3 tbsp egg whites into spinach mixture to lighten it. Then use a spatula to gently fold in remaining egg whites just until no white streaks remain. Scrape into prepared soufflé dish.

Bake until top has puffed and is golden brown, about 40 minutes. Serve hot, directly from dish.
