French Onion Potato Casserole 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 oven to 350 degrees.
• Spray non stick cooking spray on bottom and sides of large casserole dish or casserole pan.
• Empty and mix all ingredients ( except potato chips ) directly into the casserole dish/pan and spread evenly.
• Cover with foil and bake 30 minutes until dish starts to bubble at sides.
• Remove foil and cover casserole with small smashed bits of potato chips.
• Resume cooking uncovered for 15 minutes more.

Steps:

• Heat oven to 375°F. Spray 1 1/2-quart glass baking dish with cooking spray.
• Make potatoes as directed on box for stove-top directions. Stir in sour cream dip. Pour mixture into baking dish. Top with onions.
• Bake 12 to 15 minutes or until sauce is bubbling. Sprinkle with parsley. Let stand 5 minutes before serving (sauce will thicken as it stands).

Steps:

• Boil unpeeled potatoes with salt in water over high heat; reduce heat and simmer until potatoes are easily pierced with a knife but are not too soft, 15 to 25 minutes depending on size. Remove potatoes from water to cool.
• Preheat oven to 375 degrees F (190 degrees C).
• Cook bacon in a skillet over medium to medium-high heat until cooked but not quite crisp and most of the fat is rendered out, 5 to 7 minutes. Push bacon to one side of the pan and blot up some of the fat with a wadded paper towel. Add onion slices. Season with kosher salt and freshly ground black pepper and cayenne. Cook and stir over medium heat until onions are soft, sweet, and golden, about 6 minutes. Add white wine; cook for 2 minutes and deglaze pan. Remove from heat.
• Cut wheel of cheese into 2 semi-circles. Place each half cut side down and split in half to form 2 more semi-circles, each with a rind side and creamy cheese side.
• When potatoes are cool enough to handle, peel off the skin. Slice into fairly thick slices, about 1/3 inch thick.
• Place a little over half the potato slices onto bottom of a 2-quart shallow baking dish. A little overlapping is fine. Sprinkle with a bit of salt. Pour in bacon/onion/wine mixture and spread over potatoes in an even layer. Arrange the remaining potato slices over the top, overlapping as needed. Spread creme fraiche over the potatoes. Place down cheese pieces, rind side up. Transfer pan to a baking sheet. Bake in center rack of preheated oven until browned and potatoes are tender, 45 to 50 minutes.
