Potato Gratin With Spring Onions Recipes

SCALLOPED POTATOES WITH TOMATOES AND BELL PEPPERS

Steps:

• Whisk the egg yolks and 1/2 cup milk in a small bowl and set aside. Combine the remaining 1 cup milk and 1 cup cream in a medium saucepan; stir in the nutmeg, 1 teaspoon salt and 1/2 teaspoon pepper. Add the garlic and bay leaves and bring to a boil over medium heat. Reduce the heat to medium low; add the potatoes and simmer until halfway cooked, about 6 minutes. Remove from the heat. Gradually stir in the egg-milk mixture and 1 cup gruyere. Cover and keep warm.
• Preheat the broiler. Put the tomatoes, bell peppers and onion on a baking sheet in separate piles. Drizzle each pile with 2 teaspoons olive oil and sprinkle each with 1 teaspoon herbes de Provence, and salt and pepper to taste. Toss each pile of vegetables to coat, then spread out the piles. Broil until tender and charred around the edges, about 10 minutes.
• Preheat the oven to 375 degrees F. Brush a 1 1/2-quart baking dish with olive oil. Sprinkle half of the breadcrumbs (1/2 cup plus 2 tablespoons) in the dish. Spoon out half of the potatoes and arrange evenly over the breadcrumbs; top with the broiled onions and half each of the tomatoes and bell peppers. Top with the remaining potatoes in an even layer and all of the cream mixture; discard the garlic and bay leaves. Top with the remaining tomatoes and bell peppers.
• Bake until the potatoes are tender and lightly golden, 40 to 50 minutes. Drizzle with the remaining 1/2 cup cream and sprinkle with the remaining 1/2 cup plus 2 tablespoons breadcrumbs and 1/2 cup gruyere. Continue baking until the cheese melts, about 5 more minutes. Let rest 10 minutes before serving.

CARAMELIZED VIDALIA ONION AND POTATO GRATIN WITH FRESH SAGE

Steps:

• Preheat oven to 375 degrees F.
• Heat oil and butter in a large saute pan over medium-high heat. Add the onions, season with salt and pepper and cook until caramelized, about 15 to 20 minutes. Remove from the heat and stir in the sage. Let cool slightly.
• Make a layer of potato slices in a 10 by 10 by 2-inch casserole, season to taste with salt and pepper, spread 1/12 of the onion mixture over the potatoes and coat with 2 tablespoons of the cream. Repeat each step to yield 12 layers. Press down gently on the layers, place the dish on a sheet pan and bake, covered for 25 minutes. Remove cover and bake for another 20 to 25 minutes, or until the potatoes are tender and golden brown on top. Let rest 10 minutes before serving.

CREAMY POTATO GRATIN WITH CARAMELISED ONIONS

Steps:

• Up to 2 days before serving, heat oven to 200C/180C fan/gas 6. Heat the oil in a large frying pan. Add the onions and thyme, cover, and cook over a gentle heat for 10-15 mins until softened and caramelised. Pour the cream and milk into a large bowl and season well. Add the potatoes and mix to combine.
• Butter a 23 x 28cm ovenproof dish, then layer in half the potatoes. Spread the onion mixture on top, then layer on the remaining potatoes. Press down with your hands. Pour over the milk mixture, which should come just level with the potatoes. If not, add a little more milk until it does. Cover with foil, then bake for 11⁄2 hrs until tender. Remove from the oven and leave to cool. Cover and store in the fridge.
• On the day, heat the oven to 220C/200C fan/gas 7. Uncover the gratin, spread the crème fraîche on top, then sprinkle over the Parmesan. Put in the oven and cook for 30 mins until the cheese is melted, the top crisp and golden brown, and the gratin piping hot. Serve garnished with extra thyme.

POTATO GRATIN WITH SWISS CHARD AND SUMAC ONIONS

Steps:

• Heat oven to 375 degrees Fahrenheit/180 degrees Celsius.
• Prepare the onions: Add the oil to a large, ovenproof lidded skillet and heat over medium-high. Add the onions and 1 teaspoon salt to the hot oil and cook, stirring occasionally, until softened and browned, 15 to 20 minutes. Stir in the sumac and remove from the heat. Transfer the mixture to a bowl.
• Prepare the gratin: Add the potatoes, shredded chard, parsley, garlic, lemon zest, 1 tablespoon salt and 1 teaspoon pepper to a large bowl and mix well to combine. Fold through three-quarters of the sumac onions and half the cheese, then transfer everything to the skillet, smoothing out the top to even out the potato slices. In a measuring cup or bowl, combine the stock, cream and lemon juice, and pour this all over the potato mixture. Cover tightly with foil, then top with the lid. Bake for 1 hour.
• Remove the gratin from the oven, and remove the lid and foil. Sprinkle evenly with the remaining cheese and bake, uncovered, until golden and bubbling, 35 to 40 minutes. Remove from heat and let gratin settle for 10 minutes.
• Meanwhile, prepare the pine nuts: Add the butter to a medium skillet and melt over medium-high heat. Once melted, add the pine nuts and 1/4 teaspoon salt and cook, stirring occasionally, until the nuts are golden and the butter has browned, 2 to 3 minutes. Add the buttered nuts to the bowl with the remaining sumac onions.
• When ready to serve, stir the extra parsley into the sumac onion mixture and spoon this all over the gratin.
