Potato Gratin With Spring Onions Recipes

FRENCH ONION SOUP POTATO GRATIN

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!

POTATO GRATIN WITH SPRING ONIONS

Steps:

• Preheat the oven to 375 degrees F. Combine the heavy cream, thyme, bay leaves, garlic and nutmeg in a medium saucepan. Bring to a gentle simmer over medium heat. Add the spring onion whites and simmer until just starting to soften, about 5 minutes. Season with 1 1/2 teaspoons salt and a few grinds of pepper. Remove the thyme sprigs and bay leaves. Stir in about half of the spring onion greens.
• Spread the potatoes in a 9-by-13-inch baking dish. Pour the cream mixture over the top and gently stir, pressing and submerging the potatoes to make an even layer. Cover with foil and bake until the potatoes are tender and the cream is bubbling, 45 to 55 minutes.
• Uncover the potatoes and sprinkle with the cheese. Bake until the cheese is golden, 10 to 15 minutes. Let cool 15 minutes. Sprinkle with the remaining spring onion greens just before serving.

Steps:

• Preheat the oven to 375 degrees F.
• Put the cream, half-and-half, horseradish, nutmeg, garlic and onion in a medium saucepan and slowly bring the mixture to a simmer. Be sure to stir on occasion to prevent scorching. Season with salt and pepper.
• In a 9-by-13-inch baking dish, spoon a thin layer of the cream and onion mixture onto the bottom. Layer the potatoes, followed by a sprinkle of cheese. Season lightly with salt and pepper. Repeat this process until the dish is filled and the gratin is moist. Combine the breadcrumbs and thyme and sprinkle on top.
• Bake until the potatoes are tender and the gratin is caramelized on top and bubbly on the edges, 45 minutes to 1 hour. Allow to cool slightly before serving.

LEEK AND SPRING ONION GRATIN

Steps:

• Place a rack in the top third of oven and heat to 400 degrees. In a medium bowl, toss scallions, green garlic, salt and pepper.
• Heat a 12-inch cast-iron skillet over medium heat. Arrange the leeks cut-side down in the skillet, then scatter spring onions in the gaps. Sprinkle a little more salt on top, then spread scallion mixture in an even layer in pan. Pour in 1/4 cup water and top with butter.
• Cover and and simmer on low heat until vegetables are soft, 20 to 25 minutes.
• Uncover the pan, turn heat to medium-high and cook until liquid is evaporated and edges are starting to brown and sizzle, 5 to 10 minutes longer.
• Meanwhile, in a small bowl, rub together anchovies, Parmesan, panko, thyme, lemon zest and red pepper flakes. Drizzle in oil and toss to combine.
• Sprinkle Gruyère evenly into skillet over leeks, pour in cream, then top with the bread crumb mixture. Drizzle with a little more oil. Transfer to oven and bake until golden and bubbly, 15 to 20 minutes. Cool slightly, then serve warm.
