Sweet Potato And Butternut Gratin Recipes

SWEET POTATO AND GRUYèRE GRATIN

Steps:

• Heat oven to 400 degrees and generously butter a 9-by-13-inch baking pan or shallow gratin dish. Butter a piece of foil large enough to cover top of pan. Sprinkle Parmesan all over bottom of pan.
• In a medium pot, bring cream, sage, rosemary, garlic, nutmeg and a pinch of salt to a simmer. Simmer until reduced by 1/4, about 10 minutes.
• In a large, heatproof bowl, whisk eggs just enough to break them up. Slowly pour hot cream into eggs to combine, whisking while pouring, and reserve the mixture.
• Meanwhile, using a mandoline or sharp knife, slice the potatoes into 1/8-inch-thick rounds.
• Place 1 layer of potatoes in the pan, slightly overlapping as you go, using about a third of the slices. Sprinkle with 1/4 teaspoon salt and pepper to taste, then pour 1/3 of the egg mixture over potatoes. Top with 1/2 cup Gruyère. Repeat with another layer of potatoes, 1/2 teaspoon of salt, pepper and 1/3 egg mixture. Top with 1/2 cup Gruyère. Top with remaining potatoes, 1/4 teaspoon salt, pepper to taste, and remaining egg mixture (but not the remaining cheese). Press down to compact the potatoes. Cover with foil and bake until potatoes are tender, about 40 minutes, then remove foil, sprinkle top with remaining 2/3 cup Gruyère and bake until browned and bubbling, 25 to 30 minutes. Let cool slightly, then serve.

Steps:

• Preheat the oven to 400 degrees F (200 degrees C). Lightly grease a 9x13-inch baking dish.

• Arrange 1/2 of the sweet potatoes in the bottom of the prepared baking dish, pour 1/2 of the cream mixture on top, and sprinkle with 1/2 of the Gruyere cheese. Repeat layers once more; cover with aluminum foil.
• Bake in the preheated oven for 30 minutes. Remove foil and continue to bake, uncovered, until potatoes are tender and cream and cheese mixture is bubbly and golden brown, about 15 minutes. Remove from the oven and allow to sit for 10 minutes before serving.

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.
