Creamed Leek Gratin Recipes

Steps:

• Preheat oven to 375 degrees. Halve leeks lengthwise, leaving halves attached at root, and rinse well, shaking off water.
• In a large skillet, combine cream and leeks; season with salt and pepper. Bring to a boil over medium-high; reduce to a medium simmer, cover, and cook 5 minutes. Uncover and simmer until leeks are tender, 15 minutes. Transfer leeks and sauce to a shallow 2-quart baking dish.
• Sprinkle with cheese and bake until golden and bubbling, about 35 minutes. Let gratin rest 10 minutes before serving.

Steps:

• Preheat oven to 375°. Cut off the root end and the tough leaf ends, then cut leeks lengthwise in half; cut halves crosswise into 3-in. pieces. Place cream, salt, pepper and leeks in a large cast-iron or other ovenproof skillet; bring to a boil over medium-high heat. Reduce heat; simmer, covered, 5 minutes. Uncover; simmer 15 minutes. Remove from heat; sprinkle with cheese., Bake, uncovered, until top is golden and leeks are tender, 15-20 minutes. Let stand 5-10 minutes 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:

• Cut off roots of the leeks and peel off any withered leaves. Cut off 2 inches from green tops. With a sharp knife slit the green parts in half lengthwise stopping an inch from root end. Make another slit, lengthwise and perpendicular. Spread leaves apart an rinse them under running water, carefully looking out for hidden grit. Cut leeks crosswise into 1 1/2-inch lengths.
• Heat butter in a saucepan and add the leeks. Toss to combine them with the butter. Add the broth, cover and simmer for 15 to 20 minutes or until completely tender. You may do the recipe 2 to 3 days in advance up to this point. Over medium heat, evaporate the liquid from the leeks and when they are totally dry add heavy cream, starting with 1/4 cup or so and simmer, stirring continuously until the cream has been absorbed by the leeks. Add 1/4 cup more and repeat if you wish. Season to taste with salt and pepper.

Steps:

• Pour the stock, cream and milk into a small saucepan, add the garlic and bay leaf and bring to the boil. Remove from the heat, cover and let the flavours infuse while you get on with the rest of the dish.
• Preheat the oven to 180C/gas 4/fan 160C. Butter a 2 litre gratin dish well. Mix the potatoes, leeks and ham (if using) together in the dish, and spread out in an even layer. Pour over the stock mixture and tuck the bay leaf in the middle. Season and sprinkle with the cheese.
• Stand the dish on a baking tray to catch any spills. Loosely cover with foil and bake for 30 minutes. Test the potatoes with a knife - they should be just beginning to soften. Remove the foil and bake for another 35-45 minutes, spooning some of the stock mixture over every now and again until the potatoes are tender. Cool for 15 minutes before serving.

Steps:

• Heat oven to 425 degrees. Slice cauliflower head lengthwise into 1/2-inch thick slices, including the core and leaves. (Some smaller bits will fall away: That's fine. You'll use them as well.)
• Drizzle some olive oil onto the bottom of a 2-quart baking dish. (An oval, square or rectangular dish will all work.) Layer about a third of the cauliflower along the bottom, and about a third of the leeks. Season with salt and pepper, and repeat until all of the cauliflower and leeks are used. (Don't worry about perfectly layering them.) Season with salt and pepper and drizzle cream over. Scatter cheese on top, and season again with salt and pepper. Lightly cover with foil and place in the oven.
• Bake until cauliflower is nearly tender, 10 to 15 minutes. Remove foil and continue to bake until cream has thickened and reduced nearly completely and the top is golden brown and crisp, 35 to 40 minutes. Remove from oven and let cool slightly before eating.

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:

• Heat the butter in a saucepan. Add the leeks, rosemary and bay leaf, then cover and cook very gently over a medium-low heat for 15-20 mins until the leeks are soft. Pour over the milk and almost all of the cream, then season and bring to the boil. Remove from the heat and leave to cool a little, then scoop out the bay leaf.
• Pour a little of the leek mixture into an ovenproof gratin dish. Arrange a layer of celeriac in the dish, then season. Spoon over some more of the leek mixture and scatter with a little cheese. Repeat the process, alternating between layers of the leek mixture, cheese and celeriac slices, then finish with a drizzle of cream and the last of the cheese. Can be prepared up to a day ahead and kept in the fridge.
• Heat oven to 180C/160C fan/gas 4. Bake the gratin for 1 hr-1 hr 15 mins until the top is golden and the celeriac is tender when poked with a knife. If the gratin is browning a little too much, cover the dish in foil. Can be chilled, then reheated in a microwave or oven on a low heat with a drizzle more cream.
