All Crust Sheet Pan Scalloped Potatoes Recipes

Steps:

• Preheat the oven to 450 degrees F. Grease an 18-by-13-inch sheet pan with the butter.
• Put the cream, salad dressing spread, thyme, cayenne, garlic, 1/2 teaspoon salt and 1/4 teaspoon pepper in a small saucepan over medium heat. Bring to a gentle simmer, stirring often, then turn off the heat.
• Thinly slice the potatoes on a mandoline or vegetable slicer into about 1/8-inch-thick rounds. Arrange half of the potato slices in a single, overlapping layer on the prepared sheet pan and sprinkle with salt and half of the Parmesan. Top with the remaining potato slices and sprinkle with salt. Drizzle the hot cream mixture over the potatoes.
• Cover the pan with foil and bake until the potatoes are tender when pierced with a paring knife, about 20 minutes. Carefully remove the foil and sprinkle the potatoes with the Gruyere and remaining Parmesan. Cook, uncovered and rotating the pan halfway through, until the potatoes are very brown and crusty on top, 15 to 20 minutes more.

Steps:

• Preheat oven to 400 degrees F (200 degrees C). Coat an 8-inch baking dish cooking spray.
• Mix Parmesan cheese, rosemary, and garlic together in a bowl.
• Slice 3 or 4 potatoes using a mandolin on the thinnest setting. Slice remaining potatoes using a slightly thicker setting on the mandolin.
• Line the bottom of the prepared baking dish with thin potato slices, overlapping them to create a layer that is 2 to 3 slices deep. Stand remaining thin slices along the sides of the baking dish so that half an inch sticks over the rim, overlapping them to create a layer that is 4 slices deep.
• Spread 1/3 of the thicker potato slices in the baking dish. Sprinkle 1/3 of the Parmesan cheese mixture on top. Repeat once more. Arrange remaining potato slices in the baking dish. Reserve 1/3 of the Parmesan cheese mixture.
• Melt butter in a saucepan over medium heat; whisk in flour. Pour in milk; cook, stirring occasionally, until sauce thickens, 5 to 6 minutes. Stir in salt.
• Shift potato slices in a few places with a knife to create wells for the sauce to flow through. Pour sauce evenly over potato slices in the baking dish. Sprinkle remaining 1/3 of the Parmesan cheese mixture on top. Brush potato edges sticking out of the baking dish with olive oil.
• Bake in the preheated oven until potatoes are soft and edges are crusted, 60 to 75 minutes.

Steps:

• Preheat oven to 375 degrees F (190 degrees C). Grease a 9x13-inch baking dish.
• Spread about 1/3 of the potato slices into the bottom of the prepared baking dish. Top with about 1/3 of the onion slices. Sprinkle 3 tablespoons flour over the potato and onion. Arrange 2 tablespoons butter atop the flour. Season the entire layer with salt and pepper. Repeat layering twice more.
• Heat milk in a saucepan until warm. Pour enough warm milk over the mixture in the baking dish so the top of the liquid is level with the final layer of potatoes.
• Bake in preheated oven until potatoes are tender, 45 to 60 minutes.
