Sweet Potato And Butternut Gratin Recipes

Steps:

• Preheat the oven to 400 degrees F (200 degrees C). Lightly grease a 9x13-inch baking dish.
• Stir together cream, milk, butter, and garlic in a small saucepan over medium heat and bring to a simmer. Remove from heat and stir in parsley, thyme, sage, rosemary, salt, and pepper.
• Arrange 1/2 of the sweet potatoes in the bottom of the prepared baking dish, pour 1/2 of the cream mixture on top, and sprinkle with 1/2 of the Gruyere cheese. Repeat layers once more; cover with aluminum foil.
• Bake in the preheated oven for 30 minutes. Remove foil and continue to bake, uncovered, until potatoes are tender and cream and cheese mixture is bubbly and golden brown, about 15 minutes. Remove from the oven and allow to sit for 10 minutes before serving.

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.

Steps:

• Preheat oven to 375°.
• Melt butter in a small saucepan over medium-high heat. Add pancetta; cook 1 minute.

• Add to pan; cook 2 minutes, stirring constantly with a whisk. Stir in thyme.
• Gradually add milk, stirring constantly with a whisk; cook over medium heat until slightly thick (about 3 minutes), stirring constantly.
• Stir in Parmigiano-Reggiano; cook 3 minutes or until cheese melts. Stir in salt and peppers. Remove from heat.

• Cook butternut squash in boiling water 4 minutes or until almost tender; drain.
• Sprinkle vegetables evenly with remaining 1 tablespoon flour.
• Arrange potatoes and squash in alternating layers in a broiler-safe 11 x 7-inch baking dish coated with cooking spray; spoon sauce over potato mixture.
• Top with Gruyère. Bake at 375° for 40 minutes.

• Bake sweet potatoes in the preheated oven for 5 minutes. Add squash to sweet potatoes; cook until almost tender, 10 to 15 minutes. Remove and cool.
• Heat butter in a saucepan over medium heat; cook and stir onion until tender, about 10 minutes. Add flour, milk, and sage; season with garlic salt and black pepper. Cook and stir until flour is dissolved and sauce is thickened, 5 to 10 minutes.
• Remove and discard skins from sweet potatoes and squash. Thinly slice sweet potatoes and squash. Arrange sweet potato slices in the bottom of the prepared baking dish. Layer half the squash atop sweet potatoes. Pour a little less than half the cream sauce over squash. Sprinkle with half the Asiago cheese. Repeat layering with remaining squash, cream sauce, and Asiago cheese, respectively. Cover with aluminum foil.
• Bake in the preheated oven for 25 minutes. Remove foil and bake until cheese is melted and bubbling, about 10 more minutes.
