Sweet Potato Gratin With Herb Crumble 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.

• 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.

• 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.

SWEET POTATO CRUMBLE

Steps:

• Preheat the oven to 350 degrees F.
• For the mashed sweet potatoes: Cover the sweet potatoes with cold water in a medium saucepan and simmer over medium heat until fork-tender, 12 to 15 minutes. Drain off the excess water and transfer the potatoes to the bowl of a stand mixer fitted with the paddle attachment. Add the milk, cardamom and 4 tablespoons of the brown sugar and mix on medium until smooth, 3 to 4 minutes. Taste and add more brown sugar if desired. Set aside to cool.
• Spray a 9-by-13-inch baking dish with cooking spray.
• For the cake layer: In a clean bowl of a stand mixer fitted with the paddle attachment, cream together the egg and brown sugar until fluffy and thick, about 4 minutes. Add the yogurt, oil, vanilla extract and orange zest and mix until well combined. Add the flour, baking powder, baking soda and salt. Mix until the batter just comes together; it will be thick. Spread the batter into the bottom of the greased baking dish. Cover the batter evenly with the sweet potato mixture.
• For the crumble: Combine the flour, brown sugar and melted butter in a small bowl. Mix with your hands until the mixture forms a rough crumbly texture. Sprinkle over the sweet potato and bake until the bottom is set and the crumb topping is golden brown, about 30 minutes.
