Sweet Potato And Gruyère Soufflé Recipes

SWEET POTATO AND GRUYèRE GRATIN

Steps:

• Heat oven to 400 degrees and generously butter a 9-by-13-inch baking pan or shallow gratin dish. Butter a piece of foil large enough to cover top of pan. Sprinkle Parmesan all over bottom of pan.
• In a medium pot, bring cream, sage, rosemary, garlic, nutmeg and a pinch of salt to a simmer. Simmer until reduced by 1/4, about 10 minutes.
• In a large, heatproof bowl, whisk eggs just enough to break them up. Slowly pour hot cream into eggs to combine, whisking while pouring, and reserve the mixture.
• Meanwhile, using a mandoline or sharp knife, slice the potatoes into 1/8-inch-thick rounds.
• Place 1 layer of potatoes in the pan, slightly overlapping as you go, using about a third of the slices. Sprinkle with 1/4 teaspoon salt and pepper to taste, then pour 1/3 of the egg mixture over potatoes. Top with 1/2 cup Gruyère. Repeat with another layer of potatoes, 1/2 teaspoon of salt, pepper and 1/3 egg mixture. Top with 1/2 cup Gruyère. Top with remaining potatoes, 1/4 teaspoon salt, pepper to taste, and remaining egg mixture (but not the remaining cheese). Press down to compact the potatoes. Cover with foil and bake until potatoes are tender, about 40 minutes, then remove foil, sprinkle top with remaining 2/3 cup Gruyère and bake until browned and bubbling, 25 to 30 minutes. Let cool slightly, then serve.

SWEET POTATO AND GRUYèRE SOUFFLé

Steps:

• Butter a 1 1/2-quart soufflé dish and dust it with 1/4 cup of the Parmesan. In a large heavy saucepan cook the onion and the garlic with salt and pepper to taste in the butter over moderately low heat, stirring, until the onion is softened, stir in the flour, and cook the roux, stirring, for 3 minutes. Add the milk in a stream, whisking, and simmer the mixture, whisking, until it is thickened. Remove the pan from the heat, whisk in the Gruyère, whisking until the cheese is melted, and whisk in the sweet potatoes and the egg yolks, 1 at a time. In a bowl with an electric mixer beat the egg whites with a pinch of salt until they just hold stiff peaks, whisk one fourth of them into the sweet potato mixture to lighten it, and fold in the remaining whites gently but thoroughly. Pour the mixture into the prepared soufflé dish, sprinkle the remaining 1/4 cup Parmesan over it, and bake the soufflé in the middle of a preheated 375°F. oven for 45 to 50 minutes, or until it is puffed and golden. Serve the soufflé immediately.
