Sweet Potato Turnip Gratin Recipes

Steps:

• Preheat oven to 350 degrees. In an 8-inch square baking dish, arrange a single layer of turnips and sweet potatoes, overlapping slightly. Season with salt and pepper and sprinkle with one-third of the flour. Repeat to make 3 more layers, sprinkling with salt, pepper, and flour between layers. Dot top layer with butter, then slowly pour broth and wine into dish, keeping layers intact. Cover with foil and bake until vegetables are tender when pierced with a knife, 45 minutes.
• Increase oven temperature to 425 degrees. Remove foil and sprinkle cheese over dish. Bake until cheese is golden and bubbling, 12 to 15 minutes. Let gratin sit 10 minutes before serving.

Steps:

• Preheat the oven to 350°F. Butter a 3-quart casserole.
• To blanch the turnips, bring a large pot of water to the boil. Add the sliced turnips and cook 5 minutes. Remove them and drain thoroughly in a strainer.
• Gently combine the turnips and sweet potatoes. Place a layer of the vegetables in the casserole and dot with half the butter. Sprinkle generously with tarragon, salt, and pepper, and cover with half of the Parmesan. Make another layer. Top with the bread crumbs and pour the cream around the sides. Dot with the remaining butter and Parmesan. Bake until the vegetables are soft but not mushy, 1 to 1 1/2 hours.
• The gratin can be made ahead several days, or frozen for up to 3 months. Let defrost in the refrigerator and reheat for 30 to 45 minutes in the oven, or reheat in the microwave.
• Variation
• Omit the sweet potatoes and double the amount of turnips.

Steps:

• Preheat the oven to 375 degrees F (190 degrees C). Lightly butter a 9-inch gratin dish.
• Using a mandoline, slice potatoes and turnip into 1/8-inch-thick slices.
• Layer 1/2 of the potatoes and turnips in the bottom of the gratin dish. Sprinkle 1/2 of the thyme leaves over the vegetables, season with salt and pepper, and top with 1 cup shredded Monterey Jack cheese.
• Layer remaining 1/2 of the potatoes and turnips on top of the cheese. Sprinkle remaining thyme leaves over the vegetables. Season with salt and pepper again. Pour half-and-half evenly over the top and cover with remaining 1 cup Monterey Jack cheese.
• Cover and bake in the preheated oven for 40 minutes. Uncover and continue baking until browned and bubbly, about 10 more minutes. Remove from the oven and let sit 10 minutes before serving.

Steps:

• Preheat the oven to 375 degrees F.
• Place the cream, garlic, thyme and cayenne in a saucepan, and season with salt. Taste to make sure it is adequately seasoned. Bring to a boil and then turn off the heat. Steep the mixture for 15 to 20 minutes.
• Grease the baking dish and layer in one-third of the sliced turnips. Sprinkle one-sixth of the grated cheese over the turnips and dot with one-sixth of the butter. Remove the thyme and garlic from the cream and pour one-sixth of the cream over the turnips. Repeat the layering five more times, alternating the turnip with sweet potato, until all of the ingredients are used up, for a total of six layers.
• Cover the dish with foil, place on a baking sheet and bake for 35 to 40 minutes. Remove the foil and bake until golden, another 20 minutes. When done, a fork should slide in and out of the center of the dish easily.
• Rest the dish 10 to 12 minutes, then serve.

Steps:

• Preheat the oven to 375 degrees F.
• Peel the sweet potatoes, and then slice them into even rounds (1/8-to-1/4-inch thick). A mandoline or the slicing attachment on a food processor is the best way to do this.
• Place the sliced sweet potatoes in a large mixing bowl. Add the garlic, salt and pepper. Toss well to coat.
• Coat the inside of a 3-quart baking dish with the butter. Arrange an overlapping layer of sweet potatoes on the bottom of the dish in a clockwise pattern. Sprinkle around some of the Parmesan and Gruyere cheeses. Continue layering the gratin, going in a counter-clockwise direction (this will keep the gratin from falling over on your plate after it is cut). Again, add some of the cheese before adding the next layer. Continue alternating layers until the gratin is full.
• Bring the half-and-half to a simmer on the stovetop and pour it over the potatoes. Cover the baking dish with aluminum foil and place a heatproof dish on top of the foil. Place in the oven to bake for 20 minutes.
• Remove the foil from the baking dish and cover the top of the gratin with some extra grated cheese. Continue baking until the top is golden brown and bubbling, 20 to 30 minutes more. Remove from the oven and cool 20 minutes before serving.
