Olive Oil Potato Gratin Recipes

SICILIAN-STYLE POTATO GRATIN

Steps:

• Preheat oven to 350°F. Rub 13x9x2-inch glass baking dish with cut side of garlic clove. Brush dish with olive oil. Heat 2 tablespoons oil in heavy large skillet over medium heat. Add onions, sprinkle with coarse salt, and sauté until soft and beginning to brown, stirring frequently, about 13 minutes.
• Arrange 1/3 of potatoes in even layer in prepared dish. Sprinkle with coarse salt and pepper. Scatter half of onions over. Sprinkle with 2 tablespoons Pecorino Romano and 1 tablespoon capers. Repeat layering with half of remaining potatoes, coarse salt and pepper, remaining onions, 2 tablespoons Pecorino Romano, and 1 tablespoon capers. Drizzle with 1 tablespoon olive oil.
• Arrange remaining potato slices over. Sprinkle with coarse salt and pepper and remaining 1 tablespoon capers. Drizzle with remaining 1 tablespoon olive oil. Pour chicken broth over. Press down firmly on potatoes to compact gratin.
• Cover gratin tightly with foil and bake until potatoes are tender, about 1 hour 20 minutes. Uncover and sprinkle with remaining 4 tablespoons Pecorino Romano. Bake gratin uncovered until cheese is lightly browned, about 15 minutes. Let gratin stand 10 minutes at room temperature before serving.

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.

OLIVE OIL POTATO GRATIN

Steps:

• Adjust oven rack to upper middle position and heat oven to 400 degrees. Grease 13x9 inch baking dish. Combine cheese, 3 tbs oil, panko, & 1/2 tsp pepper in bowl; set aside.
• Heat 2 tbs oil in 12 inch skillet over medium heat until shimmering. Additions, 1/2 tsp salt, & 1.4 tsp pepper; cook, stirring frequently, until browned, about 15 minutes. Add garlic & 1/2 tsp thyme; cook until fragrant, about 30 seconds. Add 1/4 cup broth & cook until nearly evaporated, scraping up any browned bits, about 2 minutes. Remove from heat; set aside.
• Toss potatoes, remaining 3 tbs oil, 1 tsp salt, 1/2 tsp pepper, & remaining 1/2 tsp thyme together in bowl. Arrange half of potatoes in prepared dish, spread onion mixture in even layer over potatoes, & distribute remaining potatoes over onions. Pour remaining 3/4 cup broth over potatoes. Cover dish tightly with foil and bake for 1 hour.
• Remove foil, top gratin with reserved cheese mixture, & continue to bake until golden brown and potatoes are completely tender, 15-20 minutes. Let cool for 15 minutes.

CHEESY HASSELBACK POTATO GRATIN

Steps:

• Adjust oven rack to middle position and heat oven to 400 degrees. Combine cheeses in a large bowl. Transfer 1/3 of cheese mixture to a separate bowl and set aside. Add cream, garlic and thyme to cheese mixture. Season generously with salt and pepper. Add potato slices and toss with your hands until every slice is coated with cream mixture, making sure to separate any slices that are sticking together to get the cream mixture in between them.
• Grease a 2-quart casserole dish with butter. Pick up a handful of potatoes, organizing them into a neat stack, and lay them in the casserole dish with their edges aligned vertically. Continue placing potatoes in the dish, working around the perimeter and into the center until all the potatoes have been added. The potatoes should be very tightly packed. If necessary, slice an additional potato, coat with cream mixture, and add to casserole. Pour the excess cream/cheese mixture evenly over the potatoes until the mixture comes halfway up the sides of the casserole. You may not need all the excess liquid.
• Cover dish tightly with foil and transfer to the oven. Bake for 30 minutes. Remove foil and continue baking until the top is pale golden brown, about 30 minutes longer. Carefully remove from oven, sprinkle with remaining cheese, and return to oven. Bake until deep golden brown and crisp on top, about 30 minutes longer. Remove from oven, let rest for a few minutes, and serve.

POTATO AND PESTO GRATIN

Steps:

• Preheat the oven to 375 degrees Fahrenheit. Oil a 2-quart baking dish or gratin with olive oil. Slice the potatoes about 1/4 inch thick and place in a large bowl. Season to taste with salt and pepper, and add the pesto or pistou. Stir the mixture until the potato slices are evenly coated, then transfer to the baking dish, making sure to scrape all of the pesto out of the bowl.
• Cover the baking dish with foil or a lid and place in the oven. Bake 30 minutes, then uncover and return to the oven. Bake another 15 to 20 minutes, until the potatoes are thoroughly tender, the olive oil in the dish - now a beautiful green - is sizzling, and the top is beginning to color. Serve hot or warm.
