Best 5 Potato Gratin With Caramelized Onions And Prosciutto Recipes

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.

• Repeat twice.
• Top with remaining potatoes.
• Strain cream mixture over potatoes, shaking casserole to distribute evenly; sprinkle with remaining cheese.

POTATO GRATIN WITH CARAMELIZED ONION AND PROSCIUTTO (OR BACON)

Steps:

• First, the caramelized onions:.
• IN EACH STEP, YOU WILL NEED TO STIR ABOUT EVERY 10-15 MINUTES, UNLESS OTHERWISE NOTED.
• Cut off stem and root ends of onions, and peel away the dried skin. Slice into 1/4" slices adn gather in a large, heavy bottomed pot. A 7 qt pot works perfectly.
• Pour the oil and salt over onions and toss to combine. (NOTE: Because I fried bacon to use for the dish, I used 2 T of the bacon fat, and then added veggie oil to make up the 1/2 Cup. Gave a great other layer of flavor to the onions) Set over medium heat and cover. Cook until onions begin to wilt, for 20-30 minutes. (Don't forget the stirring!)
• Reduce heat to low and continue cooking, with pot still covered, for 45 minutes. (are you still stirring?).
• Remove the lid, increase heat to medium and cook (stirring) 30 minutes, or until most of moisture has evaporated.
• Reduce heat to low and continue cooking for about 2 hours, stirring every 20 minutes.
• Continue cooking and stirring for about 1 more hour. You'll need to watch more carefully now, stirring about every 10 minutes. Cook until onions have been reduced to a deep reddish-brown marmalade, watching that they do not dry out. When done, removed from heat and set aside to cool.
• -----------------------------.
• Slice potatoes as thinly as possible (a V-slicer works great). Place potatoes in a 3 qt heavy bottomed pot or saucepan and add milk, cream, garlic, salt and bay leaves. Cover and bring ust to a gentle simmer, then remove lid and cook until potatoes are firm but tender, 15-20 minutes.
• Heat oven to 375 and put a large cookie sheet on bottom rack to catch drips. Position another rack in center of oven.
• Rub inside of large gratin dish with generous amount of butter. Using a slotted spon, transfer about half of the potatoes to the dish, in an even layer. Stir together caramelized onions and bacon/prosciutto adn distribute evenly on top of potatoes (should be enough for a very thin layer). Top with 1/4 of the cheese.
• Put the remaning potatoes in the dish, smooth to an even layer and pour cooking liquid on top. I like to shake on a good dusting of white pepper, but this is optional. Scatter the remaining cheese over the top and bake until top is bubbly and evenly browned.
• Let sit for about 10-15 minutes before serving.

POTATO GRATIN

Steps:

• Preheat oven to 375 degrees. Peel potatoes, and place in a bowl of water to prevent discoloring. Rub inside of a 9-by-12-inch oval baking dish with cut sides of garlic. Heat cream, milk, nutmeg, and 1 1/2 teaspoons salt in a medium saucepan over medium heat until bubbles form around edge. Season with pepper. Remove from heat.
• Meanwhile, slice potatoes 1/8 inch thick; transfer to a bowl. Pour warm cream mixture over top. Mix well, using your hands to separate and coat potatoes, and transfer to prepared dish. Gently push potatoes down, and pour cream mixture from bowl over top. Sprinkle with Gruyere. Bake (with a baking sheet placed on the rack below to catch drips) until potatoes are fork tender and top is bubbling and brown, about 1 hour and 15 minutes.
