Sweet Potato Parmesan Gratin Recipes

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 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.

Steps:

• Heat oven to 375°F. Spray 13x9-inch (3-quart) baking dish with cooking spray.
• In 12-inch skillet, cook bacon over medium heat 18 to 22 minutes, stirring occasionally, until crisp. Drain on paper towels. Reserve 1/4 cup bacon for garnish. Reserve 1 tablespoon drippings in skillet.
• Add onion to skillet with drippings; cook over medium heat 5 to 7 minutes or until softened.
• In 5-quart Dutch oven, add whipping cream, broth, cooked onions, thyme, garlic, salt and pepper. Heat to boiling over medium heat. Add sweet potatoes; cook 5 minutes, stirring occasionally.
• In baking dish, layer half of the sweet potato mixture, half of the bacon and 1/2 cup of the Parmesan cheese. Repeat with remaining sweet potato mixture, bacon and Parmesan cheese. Spoon any remaining cream mixture over top. Cover with foil; bake 10 minutes.
• Meanwhile, in small bowl, mix bread crumbs and melted butter. Stir to coat.
• Remove foil; sprinkle bread crumb mixture over top. Bake uncovered 20 to 25 minutes or until potatoes are tender, top is browned and edges are bubbly. Remove from oven; let stand 15 minutes before serving. Garnish with reserved bacon and, if desired, a light sprinkling of chopped fresh thyme.

Sprinkle remaining parmesan to top layer. Cover with foil and bake for 40 minutes and then uncover and continue baking for another 25 minutes until potatoes are tender and top is brown. Let it rest for 15 minutes. Additional Notes: Substitute parmesan with goat cheese.
