Leek Gratin Recipe Jamie Oliver Recipes

CHEESY LEEKS à LA OLIVER

Steps:

• Preheat the oven to 180ºC/350ºF/gas 4.
• Trim, wash and slice the leeks, about 2cm thick, at an angle. Peel and slice the garlic, then pick the thyme leaves.
• Put a large casserole-type pan (ideally one you'd be happy to serve in) on a medium heat and add a drizzle of oil, the butter, thyme leaves and garlic.
• Cook until it begins to bubble and fry, then stir in the leeks. Continue cooking and checking on it every few minutes to stir and make sure it doesn't catch.
• At this point, you have two choices: one is good, one is great. You can either stir the rest of the ingredients into the leeks, grating in the Cheddar and Parmesan, and tearing in the brie, then put it into the oven to cook for 45 minutes uncovered, or, if you want the sweetest leeks in the world (and I think you do), do the following...
• Turn the heat under the pan down a little and cook the leeks for about 35 minutes, or until soft and intensely gorgeous, stirring every now and then.
• Season, then spoon it all into a dish, or leave in the pan.
• Stir in the cream and splash of water, grate over the Cheddar and Parmesan, then pull the brie into parts and bomb those on top.
• Pop in the oven for 15 minutes, or until golden and bubbling.

LEEK GRATIN

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.

POTATO LEEK GRATIN

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.

LEEKS AU GRATIN

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.
