Best 6 Spicy Sweet Potato 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.

SMOKED CHILE SCALLOPED SWEET POTATOES

Steps:

• Preheat oven to 375 degrees F.
• Whisk together cream and chipotle puree until smooth.
• In a 9 by 9-inch casserole dish, arrange the potatoes in even layers. Drizzle with 3 tablespoons of the cream mixture and season with salt and pepper. Repeat with the remaining potatoes, cream, and salt and pepper to form 10 layers.
• Cover and bake for 30 minutes, remove cover and continue baking for 45 minutes to 1 hour, or until the cream has been absorbed and the potatoes are cooked through and the top is browned.

GARLICKY HASSELBACK SWEET POTATOES

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.

SWEET POTATO GRATIN

Steps:

• Preheat oven to 375 degrees. Pour 1 cup cream into a large ovenproof skillet. Arrange sweet potatoes evenly in pan, season with salt and pepper, and pour remaining cream on top. Gently press on potatoes to submerge. Bring to a simmer over medium, transfer to oven, and bake 12 minutes. Press on potatoes to submerge again and bake until potatoes are tender and cream is bubbling, 8 to 10 minutes more. Sprinkle with cinnamon, ginger, and cayenne. Let cool 10 minutes before serving.
