SPINACH MUSHROOM SOUFFLE RECIPES

Steps:

• Preheat the oven to 400 degrees F. Butter the inside of a 6 to 8-cup souffle dish (6 1/2 to 7 1/2 inches in diameter by 3 1/2 inches deep) and sprinkle evenly with Parmesan.
• Melt the butter in a small saucepan over low heat. With a wooden spoon, stir in the flour and cook, stirring constantly, for 2 minutes. Off the heat, whisk in the hot milk, the nutmeg, cayenne, 1/2 teaspoon salt and 1/4 teaspoon pepper. Cook over low heat, whisking constantly, for 1 minute, until smooth and thick.
• Off the heat, while still hot, whisk in the egg yolks, one at a time. Stir in the Cheddar, 1/4 cup of Parmesan and the spinach and transfer to a large mixing bowl.
• Put the egg whites, cream of tartar, and a pinch of salt in the bowl of an electric mixer fitted with the whisk attachment. Beat on low speed for 1 minute, on medium speed for 1 minute, then finally on high speed until they form firm, glossy peaks.
• Whisk one quarter of the egg whites into the cheese sauce to lighten and then fold in the rest. Pour into the souffle dish, then smooth the top. Draw a large circle on top with the spatula to help the souffle rise evenly, and place in the middle of the oven. Turn the temperature down to 375 degrees F. Bake for 30 to 35 minutes (don't peek!) until puffed and brown. Serve immediately.

Steps:

• Preheat the oven to 375 degrees F.
• Place the spinach in a colander to drain, pressing out as much excess liquid as you can. 
• Make the bechamel sauce: Melt the butter in a medium saucepan over medium heat; add the flour and stir until it becomes a thick paste. Add the milk 1/2 cup at a time, whisking well after each addition, until you have a smooth sauce. Remove from the heat and whisk in the salt, nutmeg and pepper. Taste for seasoning. Set aside to cool slightly. 
• Beat the egg whites until just frothy with an electric mixer. Add the cream of tartar and beat on high speed until it forms firm peaks. Set aside. 
• Whisk the egg yolks in a large bowl until they are pale yellow, then add the warm bechamel sauce a bit at a time. Switch to a large rubber spatula; gently mix in the spinach, Parmesan and 1/2 cup Romano. Fold in a third of the egg whites to lighten, then gently fold in the remaining egg whites until thoroughly combined but still light and fluffy. 
• Lightly grease a 2-quart souffle dish with cooking spray or softened butter, then add the remaining 1/2 cup Romano and rotate the dish to coat the bottom and sides with the cheese. Pour in the souffle batter, then bake until puffy and golden brown, 25 to 30 minutes. Serve immediately.
