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.

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.

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!

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.

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.
