So Cal Sweet Potato And Potato Gratin Recipes

SWEET POTATO GRATIN

Steps:

• Preheat the oven to 375 degrees F. Melt the butter in a small skillet over medium heat. Add the breadcrumbs and gingersnap crumbs and cook, stirring, until lightly toasted, 3 to 5 minutes; set aside.
• Combine the heavy cream, maple syrup, thyme, allspice, 1 1/2 teaspoons salt and the cayenne in a medium saucepan. Bring to a boil, then remove from the heat.
• Butter a 3-quart baking dish. Spread a single layer of sweet potatoes in the bottom of the baking dish and pour about one-third of the cream mixture on top. Repeat to make 2 more layers of potatoes and cream. Cover with foil and bake 40 minutes. Uncover and continue to bake until the cream is bubbling and the potatoes are lightly browned and tender when pierced with a knife, 40 to 50 more minutes, sprinkling the breadcrumb mixture over the potatoes during the last 5 minutes of baking.

Steps:

• If you have a gas burner, roast the poblano peppers over the open flame, turning occasionally with tongs, until the peppers are well charred all over, about 4 minutes. If you do not have a gas burner, halve the peppers lengthwise, place them in a baking pan and broil them in a preheated broiler, skin-side up, until well charred. Place the charred peppers in a bowl and cover with plastic wrap for 10 minutes. Peel, stem and deseed the peppers, then cut into strips.
• Preheat the oven to 400 degrees F. Butter a 9-by-13-inch baking dish.
• Stir together the cream, salt, lime zest, cumin and garlic in a bowl.
• Peel the sweet potatoes and russet potatoes and thinly slice them with a mandoline (about 1/4-inch thick).
• Arrange half of the russet potatoes in the buttered baking dish. Top with half of the sliced poblanos, then half of the sweet potatoes. Top with half of the cream mixture and 1/3 cup Cotija. Repeat with the remaining ingredients (potatoes, poblanos, sweet potatoes, cream and the remaining 2/3 cups Cotija) and press down firmly to submerge the potatoes as much as possible.
• Cover the baking dish tightly with foil and bake for 35 minutes. Uncover and continue to bake until the potatoes are tender, the liquid has absorbed, and the top is browned in spots, 25 to 30 minutes more.
• Let stand 10 minutes before serving.

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.
