Yukon Gold Potato Gratin With Horseradish Gruyere And Sweet Onion Recipes

Steps:

• Heat oven to 400 degrees F. Butter a 9-inch round or oval baking dish.
• Slice potatoes 1/8-inch thick and combine thoroughly in a mixing bowl with 1/2 cup cheddar cheese, the sour cream, olive oil, garlic, thyme, salt, and pepper.
• Arrange potatoes in a neat overlapping pattern in the baking dish. Pour chicken broth over potatoes.
• Bake 35 minutes, until potatoes are nearly-tender and the cheese and potatoes are starting to brown. Sprinkle with remaining cheese and bake another 10-15 minutes.
• Garnish with thyme sprigs.

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:

• Prepare a grill for medium-high heat. Preheat the oven to 350 degrees F. Grease a 9-by-13-inch baking dish with the butter.
• Oil the sliced sweet potatoes and onions with the canola oil and sprinkle with salt and pepper. Grill the sweet potatoes and onions until slightly charred on each side and just halfway cooked. Set aside.
• Combine the half-and-half, horseradish, thyme, 2 teaspoons salt and 1 teaspoon pepper in a bowl. Sprinkle one-third of the Gruyere in an even layer over the bottom of the prepared baking dish. Layer one-third of the grilled sweet potatoes and onions on top of the Gruyere. Repeat twice¿one-third of the cheese, one-third of the vegetables¿to create three even cheese-vegetable layers. Pour the half-and-half mixture over the top, cover with foil and bake for 35 to 40 minutes. Uncover and continue baking until the sweet potatoes are tender and the gratin is golden brown, another 15 to 20 minutes. Let rest for 15 minutes before serving.

Steps:

• Place rack in middle position and preheat oven to 400°F.
• Generously butter a 2 1/2- to 3-quart gratin dish or other shallow baking dish.
• Make a bouquet garni by wrapping thyme, peppercorns, and bay leaf in 6-inch square of cheese cloth and securing with kitchen string.
• In heavy, 6-quart saucepan, combine potatoes, bouquet garni, salt, garlic cloves, and cream. Set over moderate heat and bring to a boil. Reduce heat to low and simmer, uncovered, until potatoes can just be pierced with a fork, about 10 minutes. Using slotted spoon, remove bouquet garni and garlic and discard. Stir in horseradish.
• Spread potato mixture in buttered dish and sprinkle with cheese. Bake until top is golden brown and potatoes are tender, about 30 to 40 minutes. Let stand 15 minutes before serving.

Steps:

• Heat oven to 400 degrees. Butter a 9-inch round or oval baking dish.
• Slice potatoes 1/8 inch thick and combine thoroughly in a mixing bowl with 1/3 cup of the Gruyere, the olive oil, thyme leaves, salt, and pepper.
• Arrange potatoes in a neat overlapping pattern in the baking dish. Pour chicken stock over potatoes and sprinkle remaining cheese over top. Bake until potatoes are tender and the cheese and potatoes are starting to brown, about 45 minutes. Garnish with thyme sprigs.

Steps:

• Heat oven to 400 degrees. Seasoning each layer with salt and pepper as you go, layer the potatoes in a 10- or 12-inch ovenproof skillet.
• Dot the top with 2 tablespoons butter. Pour in half-and-half. (It should come about 3/4 of the way to the top.)
• Bring to a boil over medium-high heat. Reduce to low and cook for 10 minutes, uncovered, until the half-and-half has reduced by about half.
• Transfer to the oven and bake until the top is golden brown, about 10 minutes. Reduce heat to 300 degrees and cook until the potatoes are fork tender and the top is nicely browned, about 8 minutes more. Top with grated cheese and return to the oven until the cheese is melty and golden brown, about 3 to 5 minutes. Sprinkle with a pinch of nutmeg, if using, and serve.
