Potato Tomato Gratin Recipes

POTATO GRATIN

Steps:

• Preheat the oven to 400 degrees F.
• Add the cream and milk to a large saucepan over medium-low heat and bring to a gentle simmer. Add the nutmeg, a big pinch of salt and some pepper. Meanwhile, slice the potatoes on a mandoline to 1/8-inch thick. Place the potatoes in the warm cream mixture and simmer gently until the potatoes are two-thirds of the way cooked and the cream has thickened, about 15 minutes.
• Place a 9-by-12-inch flameproof gratin dish on the stove over low heat. Brush the bottom and the sides with the melted butter. Spread the garlic around the bottom of the dish. Cook just long enough to toast the garlic in the butter, 3 to 4 minutes. Add a layer of the potato mixture. Combine the Gruyere and Parmesan in a bowl, then sprinkle a third of the cheese over the potatoes. Repeat the layering 2 more times, finishing with the remaining cheese. Pick the thyme leaves and sprinkle over the top, mixing with last layer of cheese. Place the gratin dish on a rimmed baking sheet and bake until bubbly and golden, 45 to 50 minutes (see Cook's Note).

POTATO, ZUCCHINI, AND TOMATO GRATIN

Steps:

• Preheat oven to 375 degrees with rack in upper third. Coat a 9-by-13-inch gratin dish with 1 teaspoon oil, and sprinkle with garlic. Using a mandoline or a very sharp knife, slice potatoes and zucchini as thinly as possible into rounds. Arrange potatoes, zucchini, and tomatoes in overlapping layers around prepared dish, and sprinkle with the salt and pepper. Drizzle with remaining 4 teaspoons oil, and sprinkle with thyme and cheese.
• Cover with foil; bake until potatoes are tender, 35 to 45 minutes. Remove foil; continue baking until top is golden brown, about 25 minutes more. Remove from oven; and serve immediately.

POTATOES AND TOMATOES AU GRATIN

Steps:

• Grill bacon until crisp and crumble.
• Preheat oven to 375F and butter an earthenware dish.
• Combine cheese and breadcrumbs, parsley, chives and season (I often add a minced clove of garlic, too).
• First put a layer using 1/2 of the potatoes, then 1/3 of the tomatoes, sprinkle with 1/2 of cheese and 1/2 of bacon; repeat layering one more time in the same manner; finally, top with remaining tomatoes; drizzle cream over.
• Bake 40-45 minutes, until tender and browned.

BAKED TOMATO, GRUYèRE & POTATO GRATIN

Steps:

• Heat oven to 180C/160C fan/gas 4. Generously grease a large, deep, ovenproof dish. Strip the leaves from 3 of the thyme sprigs. Mix the gruyère with all but 2 tbsp of the grated parmesan, then mix the double cream with the stock.
• Start layering up the sliced potatoes with sprinklings of the shallots, garlic, thyme leaves, cheese and most of the walnuts, plus plenty of seasoning. Drizzle a little of the cream mixture over each layer too. When you've layered in half of those ingredients, top with half of the tomatoes. Continue layering the rest of the ingredients, finishing with the last of the cream. Top with the remaining tomatoes, then sprinkle over the breadcrumbs, the remaining parmesan and walnuts, and enough thyme to look pretty. Add a few more knobs of butter, then cover with foil.
• Bake the gratin for 1 hr 15 mins, then remove the foil and bake for a further 40 mins until golden and crispy on top, and a knife poked into the centre of the potatoes slides in easily. Leave to rest for 10-15 mins, then serve.

SMASHED-POTATO TOMATO GRATIN

Steps:

• In a 4-quart heavy kettle cover potatoes with salted cold water by 2 inches and simmer until tender, about 30 minutes. While potatoes are simmering, in a small saucepan heat milk with 6 tablespoons butter over moderate heat until butter is melted. Remove pan from heat and keep mixture warm, covered. Pit olives and separately chop olives and scallions. In a colander drain potatoes and when just cool enough to handle, peel. Coarsely smash potatoes with a potato masher and gently fold in milk mixture, olives, scallions, and salt and pepper to taste.
• Preheat oven to 400°F. and butter a 3-quart gratin dish (about 15 by 10 by 2 inches).
• Mince garlic and chop parsley. In a nonstick skillet heat remaining 2 tablespoons butter over moderate heat until foam subsides and cook garlic, stirring, until fragrant, about 1 minute. Add bread crumbs and cook, stirring, until golden. Transfer mixture to a bowl and cool. Stir in parsley and Parmesan and season with salt and pepper.
• Cut tomatoes into 1/4-inch-thick slices. Spread potatoes in gratin dish and top with tomatoes, overlapping them to completely cover potatoes. Sprinkle crumb mixture over tomatoes and bake gratin in middle of oven until top is golden brown and tomatoes are tender, about 25 minutes. Gratin may be made 1 day ahead and cooled completely, uncovered, before being chilled, covered. Reheat gratin, uncovered.

POTATO, TOMATO AND ONION GRATIN

Steps:

• Bring pot of water to boil. Add tomatoes and blanch 10 seconds. Drain tomatoes. Peel, core and slice tomatoes. (Can be made 6 hours ahead; cover and chill).
• Preheat oven to 400°F
• Arrange half the potatoes in a shallow baking dish (15 cup capacity). Season with salt and pepper. Top with half the onions and half the tomatoes. Sprinkle with half the garlic and half the thyme. Season with salt and pepper. Repeat layering with remaining potatoes, onions, tomatoes, garlic and thyme. Season with salt and pepper. Pour wine and olive oil over. Bake until potatoes are tender and almost all the liquid evaporates, about 90 minutes.

JULIA CHILD'S PROVENçAL POTATO GRATIN

Steps:

• Heat oven to 400 degrees and place a rack at the middle level. In a large saucepan, combine onions and 2 tablespoons olive oil and stir to coat over low heat. Sprinkle lightly with salt. At a gentle simmer, cook uncovered until onions are softened and lightly golden, 10 to 15 minutes, stirring often. Do not brown; lower the heat if necessary. When done, fold in tomatoes just until heated through. Set aside.
• In a small food processor or a mortar, add the anchovies - anywhere from 6 to 12 fillets, depending on their size and your taste. Add garlic, herbs and a dozen grinds of pepper. Add 2 tablespoons olive oil (or use the oil from the anchovy can, if you like). Crush or pulse together into a chunky paste, thinning with oil as needed to make a loose, fluid mixture.
• In a medium-size baking dish, spread a quarter of the onion-tomato mixture. On top, arrange half the potato slices, then half the anchovy mixture. Add half the remaining onion-tomato mixture. Build one more layer with remaining potato slices, anchovy mixture and onion-tomato mixture. Sprinkle cheese on top and drizzle with olive oil.
• If the dish is very full, place on a baking sheet. Transfer to oven and bake, uncovered, until potatoes are tender and have absorbed all of the juices in the bottom of the dish, 40 to 50 minutes. Test by tasting a bit of potato; it should be soft all the way through, with no raw taste. If the top is browning too fast, cover very loosely with a sheet of foil. If the top is not brown enough when the potatoes are cooked, broil briefly until deliciously glazed.
• Serve gratin hot or warm. Can be cooled and reheated later the same day, but do not refrigerate.
