Potato Gratin With Walnuts Recipes

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.

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.

POTATO MUSHROOM GRATIN

Steps:

• Preheat the oven to 425°F/220°C/Gas 7.
• Coat a 9-inch square casserole or baking dish with olive oil, and lay the rosemary sprig on the bottom.
• Layer half of the potato slices over the bottom of the dish and top with half of the sliced mushrooms, half of the garlic, half of the thyme and half of the walnuts; and sprinkle generously with the olive oil, salt, and pepper.
• Top with the remaining potatoes, then scatter the remaining mushrooms, garlic, thyme and walnuts over the top of the mixture, and sprinkle with olive oil, salt and pepper.
• Bake, uncovered, until the top is golden and crusty, about 1 hour.
• Serve hot.

WALNUT-SAGE POTATOES AU GRATIN

Steps:

• Peel potatoes, if desired, and thinly slice - I used the thin slicing blade on the food processor - (should have 6 cups).
• Place slices in a colander.
• Rinse with cool water; set aside to drain.
• For sauce, in a medium saucepan on med to med-high heat (I have found walnut oil doesn't have a high heat tolerance)cook onion and garlic in walnut oil until tender but not brown.
• Stir in flour, salt, and pepper.
• Add milk all at once.
• Cook and stir over medium heat until thickened and bubbly. Remove from heat; stir in snipped sage.
• Grease a 2-quart round casserole (with glass cover).
• Layer half of the potatoes in casserole. Cover with half the sauce.
• Sprinkle with half the cheese.
• Repeat layering with the potatoes and sauce. (Cover and chill remaining cheese until needed.).
• Bake casserole, covered, in conventional oven at 350 degrees F for 40 minutes. Uncover; bake 25 minutes more or until potatoes are just tender.
• Sprinkle remaining cheese and nuts over top. Bake, uncovered, 5 minutes.
• Let stand 10 minutes.
• Top with sage leaves.

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.

POTATO GRATIN WITH WALNUTS

Steps:

• Preheat the oven to 400°F. Grease the bottom and the sides of a 13 x 9 inch pan or a rectangular 12-inch long gratin dish liberally with the butter and spread the minced garlic evenly on the bottom.
• Assemble the gratin: Combine the potato slices with the cream, 1 cup walnuts, 1/2 cup Parmesan cheese, Gruyere cheese, milk, nutmeg and a generous handful of salt. Mix to blend. Taste the cream for seasoning. Transfer to the prepared baking dish and spread to form an even layer.
• Make the crust and cook the gratin: Combine the panko with the remaining 1/2 cup walnuts and remaining 1/2 cup Parmesan cheese. Top the potatoes with the crust. Cover the dish with aluminum foil and place in the center of the oven. Bake for 20 minutes then remove foil and continue baking for an additional 25-30 minutes or until potatoes in center are fully tender when pierced with the tip of a knife. Remove from oven and let sit for 15-20 minutes.
• Roast the tomatoes: Arrange the tomato halves, cut side up, on a baking sheet. Season with salt and drizzle with 1 tablespoons of olive oil. Place the tray in the center of the oven and bake until the tomatoes are roasted and tender, 12-15 minutes. Set aside.
• Make the vinaigrette: Meanwhile, whisk together the remaining 3 tablespoons olive oil, red wine vinegar and mustard. Set aside.
• Finish the gratin: Serve the gratin in the dish it was cooked inches Top with the tomatoes and drizzle the top with the vinaigrette.
