Potatoes With Leeks And Gruyère Recipes

Steps:

• Preheat oven to 350 degrees. Butter a 12-cup baking dish. Melt butter in a skillet over medium heat. Add leeks, and cook until translucent, 3 to 4 minutes.
• Arrange 1/3 of the potatoes in dish, slightly overlapping slices. Sprinkle with 1/2 of the salt, 1/2 of the nutmeg, and pepper, followed by 1/2 of the leeks and 1/3 of the cheese. Repeat. Top with remaining potatoes in a spiral. Sprinkle with remaining cheese. Combine cream and stock. Pour over cheese and potatoes. Cover with parchment and foil. (Mixture can be refrigerated overnight.)
• Bake for 30 minutes. Increase temperature to 425 degrees, uncover, and cook until top is golden brown and potatoes are tender, about 45 minutes. Let rest for 15 to 30 minutes before serving.

Steps:

• Heat oven to 350 degrees and butter a 2-quart gratin dish. Wash the leeks to remove any grit and slice thinly crosswise.
• Using a mandoline or sharp knife, slice the potatoes into rounds, 1/8-inch thick. Toss with 3/4 teaspoon salt and 1/4 teaspoon pepper. Layer the rounds in the gratin dish.
• Melt the 2 tablespoons butter in a large skillet over medium heat. Add leeks, remaining salt and pepper, and thyme. Cook, stirring, until leeks are tender and golden, 5 to 7 minutes. Discard thyme and scatter the leeks over the potatoes.
• Add cream, garlic and bay leaf to the skillet, scraping up browned bits of leeks from the bottom of the pan. Simmer gently for 5 minutes. Stir in nutmeg.
• Pour the cream over the leeks and potatoes and top with the Gruyère. Cover with aluminum foil and transfer to the oven. Bake for 40 minutes, uncover and bake until the cheese is bubbling and golden, 15 to 20 minutes longer. Let cool slightly before serving.

Steps:

• Preheat oven to 400°F with rack in middle. Generously butter a 3-qt shallow baking dish. Cut a round of parchment paper to fit just inside a 12-inch heavy skillet, then set parchment aside.
• Halve leeks lengthwise, then cut crosswise into 1 1/2-inch pieces (you should have about 8 cups). Wash leeks.
• Cook leeks in butter with 1/2 tsp salt and 1/4 tsp pepper, covered with parchment round, in skillet over medium heat, stirring occasionally, until tender, 10 to 12 minutes.
• Meanwhile, peel potatoes and slice crosswise 1/16 inch thick with slicer. Transfer to a large heavy pot with cream, milk, thyme, 1 tsp salt, and 1/2 tsp pepper and bring to a boil over medium heat, stirring occasionally (liquid will thicken). Stir in leeks, then transfer to baking dish.
• Bake, uncovered, until potatoes are tender, 45 minutes to 1 hour. Let stand 10 minutes before serving.
• Do Ahead
• Gratin can be baked 2 days ahead and chilled. Let stand at room temperature 30 minutes, then reheat, covered, in a 350°F oven until hot, about 30 minutes.

Steps:

• Preheat oven to 350°F Butter 13x9x2-inch baking dish. Melt 2 tablespoons butter in large skillet over medium heat. Add leeks; saute until tender, about 10 minutes. Transfer to large bowl.

Add garlic and sauté until mushrooms are tender and golden, about 3 minutes longer. Transfer mushroom mixture to bowl. Melt remaining 2 tablespoons butter in same skillet over medium-high heat. Add leeks and thyme and sauté until leeks are tender and beginning to brown, about 8 minutes. Add leek mixture to bowl with mushrooms. (Can be made 1 day ahead. Cover and refrigerate.)
• Preheat oven to 400°F. Butter 13 x 9 x 2-inch baking dish. Whisk broth, cream, wine, 1 teaspoon salt and 1/2 teaspoon pepper in large bowl to blend. Layer 1/3 of potatoes on bottom of prepared dish. Top with half of mushroom-leek mixture, then 3/4 cup cheese. Top with half of remaining potatoes. Pour half of cream mixture over. Top with remaining mushroom-leek mixture and 3/4 cup cheese. Cover with remaining potatoes. Pour remaining cream mixture over; sprinkle with remaining cheese.
