Potato Gratin With Walnuts Recipes

WALNUT SAGE GRATIN

Steps:

• Put the oven rack in center of the oven and preheat to 350 degrees F.
• In a saucepan over low heat, add the cream and 3/4 cup of the walnuts. Bring just to a simmer and then keep warm over lowest heat while building the potato layers.
• In a large, lightly greased, 9 by 13-inch baking dish, arrange 1/3 of the potato slices covering the bottom of the dish, overlapping slightly. Generously season with salt and pepper and sprinkle with a little sage, 1/3 of the Gruyere and a ladle of warmed walnut cream mixture. Repeat 1 more time the exact same way. Layer for a 3rd and last time with just the potatoes, making sure to arrange them in nice straight even rows. Then cover the top of the potatoes with the remaining warmed walnut cream and top with the last 1/3 cup of the cheese. Sprinkle with salt and pepper, to taste.
• Cover with foil and bake for 30 minutes. Reduce the oven temperature to 325 degrees and remove the foil. Continue to bake until the top is just starting to become golden, about 20 minutes more.
• Remove from the oven and do your best to let the gratin rest for 15 to 20 minutes before serving. Eat and enjoy!

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.

ENDIVE AND POTATO GRATIN WITH WALNUTS

Steps:

• Preheat the oven to 400 degrees. Oil a two-quart baking or gratin dish. Bring a large pot of water to a boil. Fill a bowl with ice water. When the water comes to a boil, salt generously and add the endives. Blanch for two minutes, and transfer to the ice water. Cool in the ice water, then drain and dry on paper towels. Cut crosswise into thirds, and transfer to a bowl.
• Steam the quartered potatoes for 10 to 15 minutes until tender. If the potatoes are large, cut the quarters in half. Add to the bowl with the endives, along with the walnuts, parsley, thyme, walnut oil and half the Gruyère. Season with salt and pepper, and toss everything gently together. Turn into the prepared baking dish, making sure to scrape all of the contents of the bowl into the dish. Sprinkle the remaining Gruyère over the top.
• Place in the oven and bake 20 to 25 minutes, until the edges of the vegetables are browned and the gratin is sizzling. Remove from the heat and serve hot or warm.

JULIA CHILD'S PROVENçAL POTATO GRATIN

Steps:

• Heat oven to 400 degrees and place a rack at the middle level. In a large saucepan, combine onions and 2 tablespoons olive oil and stir to coat over low heat. Sprinkle lightly with salt. At a gentle simmer, cook uncovered until onions are softened and lightly golden, 10 to 15 minutes, stirring often. Do not brown; lower the heat if necessary. When done, fold in tomatoes just until heated through. Set aside.
• In a small food processor or a mortar, add the anchovies - anywhere from 6 to 12 fillets, depending on their size and your taste. Add garlic, herbs and a dozen grinds of pepper. Add 2 tablespoons olive oil (or use the oil from the anchovy can, if you like). Crush or pulse together into a chunky paste, thinning with oil as needed to make a loose, fluid mixture.
• In a medium-size baking dish, spread a quarter of the onion-tomato mixture. On top, arrange half the potato slices, then half the anchovy mixture. Add half the remaining onion-tomato mixture. Build one more layer with remaining potato slices, anchovy mixture and onion-tomato mixture. Sprinkle cheese on top and drizzle with olive oil.
• If the dish is very full, place on a baking sheet. Transfer to oven and bake, uncovered, until potatoes are tender and have absorbed all of the juices in the bottom of the dish, 40 to 50 minutes. Test by tasting a bit of potato; it should be soft all the way through, with no raw taste. If the top is browning too fast, cover very loosely with a sheet of foil. If the top is not brown enough when the potatoes are cooked, broil briefly until deliciously glazed.
• Serve gratin hot or warm. Can be cooled and reheated later the same day, but do not refrigerate.

CELERIAC & WALNUT GRATIN

Steps:

• Heat oven to 190C/fan 170C/gas 5. Peel, quarter and very thinly slice the celeriac - this is best done with the slicing blade of a food processor. Toss in the walnut oil, salt and pepper, and spread over a gratin dish. Pour over the stock and bake for 40-45 mins, then sprinkle with the walnuts, crumble over the cheese, then cook for 15 mins until crisp and golden.

BUTTERNUT SQUASH AND (SWEET) POTATO GRATIN WITH WALNUT CRUST

Steps:

• Heat oven to 350°F.
• Grease an 8x8 inch (2 quart) glass or ceramic baking dish.
• Cut the squash in half lengthwise and scrape out the seeds and fibers.
• Slice the squash and potatoes about 1/8 inch thick (use a mandoline if you have one).
• Line the bottom of the baking dish with a layer of squash (overlapping slightly), season lightly with salt and pepper, sprinkle with a little of the Parmesan, and drizzle with a little of the cream.
• Cover with a layer of potato slices, season with salt, pepper, cheese, and cream.
• Repeat with the remaining squash and potatoes until the dish is full, ending with a top layer of squash, seasoned and topped with any remaining cheese and cream. (You may have extra squash, and extra potatoes if you used sweet potatoes!).
• Press down lightly to distribute the cream and compact the layers.
• The last layer of squash should be just sitting in the cream, but not covered by it.
• Cover the dish with foil and bake until the vegetables feel tender when poked with a thin, sharp knife (check the middle layer), about 1 hour, 10 minutes.
• Combine the walnuts and buttered bread crumbs.
• Remove the gratin from the oven, sprinkle with the breadcrumb-nut mixture, and bake until the top is lightly browned, 5 to 10 minutes.
• Let sit in a warm place for 20 minutes before serving so that liquids will set and tighten the gratin.
• Cut into 9 squares and serve.
