Curried Sweet Potato Gratin Recipes

Steps:

• Preheat oven to 350°F. Cook sweet potatoes in large pot of boiling salted water until just tender, about 20 minutes (do not overcook). Drain well and cool. Peel sweet potatoes; cut into 1/4-inch-thick slices.
• Mix curry powder, cumin, cinnamon, ginger, and salt in small bowl to blend. Completely line bottom of 9-inch-diameter springform pan with sweet potato slices, filling in any spaces with cut-up sweet potato slices. Press down lightly. Spread 1/2 cup sour cream over sweet potatoes. Sprinkle 1 tablespoon spice mixture over sour cream. Sprinkle with 1 cup cheese. Repeat twice with remaining sweet potatoes, sour cream, spice mixture, and cheese. Place pan on rimmed baking sheet; bake until cheese is melted and sweet potatoes are heated through, about 40 minutes. DO AHEAD Can be made 8 hours ahead. Cover and chill. If desired, reheat in 400°F oven until hot, about 15 minutes.
• Remove pan sides from gratin; cut into wedges. Serve gratin warm or at room temperature.

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 oven to 425°. Place sweet potatoes in a large bowl. Mix oil and seasonings; drizzle over sweet potatoes and toss to coat. Transfer to an ungreased 15x10x1-in. baking pan., Roast 15-20 minutes or until tender, turning occasionally. Sprinkle with cilantro. If desired, serve with chutney.

Steps:

• Preheat the oven to 400 degrees F (200 degrees C). Grease a baking dish with cooking spray.
• Combine cream, butter, and garlic in a saucepan. Bring to a simmer; remove from heat and mix in parsley, thyme, sage, rosemary, salt, and pepper.
• Arrange 1/2 of the sweet potato slices in the prepared baking dish; cover with 1/2 of the Gruyere cheese. Pour cream mixture on top. Arrange remaining sweet potato slices over the cream. Sprinkle remaining cheese on top.
• Bake in the preheated oven until golden brown and bubbly, about 30 minutes.

Steps:

• Place potatoes in a greased 8-in. square baking dish. In a bowl, beat egg. Add cream, salt, nutmeg and pepper; mix well. Pour over potatoes; sprinkle with cheese. Bake, uncovered, at 375° until the potatoes are tender, 40-45 minutes. If desired, top with fresh thyme to serve.

Steps:

• Heat the oven to 425 degrees. Pour 1 tablespoon olive oil into a large cast-iron skillet, swirl it so it coats the whole pan, then put it in the oven while you cut the potatoes.
• Cut the potatoes in half lengthwise, place cut side down on a cutting board, then use a knife to make 1/8-inch slices on a slight bias from the top to the bottom of the potato half. Cut almost all of the way through the potato, stopping before you reach the bottom. (A serrated knife makes the job easier. You can also lay chopsticks down on either side of the potato to keep the knife from slipping through the potato.)
• Carefully remove the skillet from the oven and nestle the sweet potato halves inside in a single layer. Drizzle the top of each with 1/2 teaspoon olive oil, sprinkle with salt, then bake for 30 minutes.
• Meanwhile, add the butter to a small pot with 1 teaspoon salt. Grate the garlic into the pot with a microplane, then heat over low until the butter is melted.
• Take the sweet potatoes out of the oven and, keeping in mind that the pan is hot, use a fork or offset spatula to gently pry the slices apart so that there's more room between each one. Use a brush to generously coat the potatoes with garlic butter (the more you get inside the slices, the better). Reserve any excess.
• Bake for an additional 10 minutes. For extra crisp edges, broil potatoes for 2 to 4 minutes, until the ruffles are charred. Brush with reserved garlic butter, and serve.
