Potato Gratin French Recipes

Steps:

• For the caramelized onions: In a large saucepan over medium-high heat, melt the butter. Once melted and bubbling, add a large handful of the onions and cook until translucent, 1 to 2 minutes. Repeat until all the onions have been added. Season with a pinch of salt and black pepper. Reduce the heat to low and cook, stirring occasionally, until the onions turn medium brown, about 30 minutes. If the onions start to get too dark, add 1 to 2 tablespoons of beef stock as necessary. Add the sherry to deglaze the pan. Add the mustard and stir to coat. Season with salt and pepper. Remove from the heat and set aside.
• For the potato gratin: Preheat the oven to 400 degrees F.
• Using a mandoline or a sharp knife, cut the potatoes into thin slices. Do your best to keep the potatoes in a stack--this will make it easier to layer them in the pan. Set the potatoes aside.
• Use the reserved butter wrapper to lightly grease the bottom and sides of a large (12-inch) cast-iron skillet. Discard the wrapper.
• Arrange a thin shingled layer of potatoes in concentric circles around the skillet. Season the potatoes with salt and pepper, then arrange an even layer of caramelized onions on top of the potatoes. Season with salt and pepper.
• In a medium bowl, combine the Gruyere and mozzarella and reserve half for later use. Sprinkle on a layer of the remaining cheese mixture over the onions. Repeat the layers until all the ingredients (not including the reserved cheese) have been used. Press down firmly on the layers to flatten.
• In a large bowl or measuring cup, combine the heavy cream and beef stock and pour over the gratin. Cover the skillet with foil and place on a sheet pan. Bake the potatoes, covered, until the top and edges have begun to brown and the potatoes are tender, 1 hour 15 to 1 hour 30 minutes. You can test by inserting a knife into the potatoes; if it goes in and comes out without resistance, then the potatoes are done.
• Remove the skillet from the oven, remove the foil and turn the broiler on high. Combine the croutons and French fried onions. Cover the gratin with a layer of the crouton mixture followed by the remaining cheese. Broil until golden brown and bubbly, 5 to 8 minutes. Serve and enjoy!

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).

Steps:

• Peel and slice potatoes thinly.
• Use a food processor if available.
• Lightly grease an ovenproof casserole.
• Layer potato slices in casserole, sprinkling each layer with salt, pepper and nutmeg.
• Press garlic over mixture.
• Add cream and milk.
• You may prepare ahead of time up to this step.
• Bake at 400 degrees F for about 40 minutes, or until potatoes are soft and creamy and golden brown on surface.

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.

Steps:

• Preheat the oven to 300F/150C/gas mark 2.
• Take a heavy-bottomed dish or an ovenproof gratin dish (a Le Creuset is ideal - the potatoes tend not to catch), and grease it will with some of the butter.
• Layer the potato slices in the dish, slightly overlapping each other, seasoning lightly with the salt and pepper, and sprinkling a liberal amount of cheese on each layer.
• Sprinkle cheese on the top of the last layer.
• Put the double cream, garlic and sprigs of thyme in a pan and bring to them gently to the boil, then remove the thyme and pour hot cream over the potatoes.
• Dot the top of the gratin with the remaining butter and some extra cheese if you wish, and bake for about 1 hr to 1 1/2 hrs, or until the potatoes are soft, and the top is crispy and golden brown.
• Serve bubbling hot as a main meal or as an accompaniment.
