Root Vegetable Au Gratin Recipes

ROOT VEGETABLE AU GRATIN

Steps:

• Preheat the oven to 350 degrees F. Spray a 9 by 9-inch baking dish with cooking spray.
• In a small pot, heat the milk with the thyme over medium-low heat until hot.
• In a medium saucepan over medium heat, melt the butter with the canola oil. Add the garlic and cook 1 minute. Add the flour and cook stirring constantly until the flour is lightly golden brown, about 2 minutes. Slowly whisk in the hot milk. Bring the mixture to a simmer and cook until very thick. Stir in the Cheddar, pumpkin pie spice and salt and pepper to taste.
• Coat the bottom of the prepared baking dish with a thin layer of the sauce. Place one layer of carrots slightly overlapping in the bottom of the baking dish. Top with an overlapping layer of the parsnips. Pour a third of the sauce over top. Repeat with two more layers each of the carrots and parsnips, ending with the sauce.
• In a small bowl, stir together the breadcrumbs, Parmesan, parsley and salt and pepper to taste. Evenly sprinkle over the top of the gratin.
• Bake until the gratin is bubbling and the topping is browned, and when pierced through the vegetables yield easily, about 1 1/2 hours. If the top begins to brown too quickly, cover with foil. Let rest for 10 minute before serving.

Steps:

• 1. Preheat the oven to 400 degrees F. Lightly grease a 13- x 9-inch baking dish. Using a mandoline or sharp knife, cut the potatoes, beet, fennel and parsnips into 1/8-inch-thick slices. Toss together the vegetable slices, salt, and 3/4 cup of the cream in a large bowl.
• 2. Spread half of the mixture evenly in the prepared baking dish. Top with 1 cup of the Parmesan. Top evenly with the remaining vegetable mixture. Pour the remaining 3/4 cup cream over the vegetables, and top with the remaining 1/2 cup Parmesan. Cover loosely with aluminum foil. Bake for 1 hour and 10 minutes.
• 3. Uncover and bake until the vegetables are tender and the cheese is golden brown, another 20 to 25 minutes. Transfer to a wire rack; cool for 15 minutes before serving with some black pepper ground over the top.

Steps:

• Preheat the oven to 375 degrees F (190 degrees C).
• Bring a large pot of generously salted water to a boil. Add the vegetables, and cook uncovered for 3 minutes. Drain in a colander, then immediately immerse in ice water for several minutes until cold to stop the cooking process. Once the vegetables are cold, drain well, and set aside.
• Cook garlic and butter in a large skillet over medium heat until garlic starts sizzling, about 3 minutes.
• Stir in chicken broth, heavy cream, thyme, nutmeg, and cayenne pepper; cook until mixture begins to simmer, about 5 minutes.
• Coat a 9x13-inch baking dish with olive oil and spread vegetables evenly over the oil.
• Pour broth and cream mixture over vegetables and top with half of the grated Parmigiano-Reggiano cheese.
• Cover baking dish loosely with aluminum foil, place on a baking sheet, and bake in the preheated oven for 40 minutes.
• Remove baking dish from the oven and top with remaining Parmigiano-Reggiano. Bake uncovered until vegetables are browned, bubbling, and tender, about an additional 30 minutes.
• Remove from the oven and let rest for 20 minutes.

Steps:

• Preheat oven to 400 degrees F. Coat a 9-by-13-inch baking dish with cooking spray.
• If using parsnips, quarter lengthwise and remove the woody core before cutting into 1/8-inch thick slices. Cook vegetables in a large pot of boiling water until barely tender, about 5 minutes. Drain.
• Heat 2 tablespoons oil in a medium saucepan over medium heat. Add shallots and cook, stirring occasionally, until light brown, 3 to 4 minutes. Add 1 cup milk and bring to a simmer. Combine flour and the remaining 1/3 cup milk in a small bowl to make a smooth paste; stir into the hot milk and cook, whisking constantly, until the sauce bubbles and thickens, 1 to 2 minutes. Remove from the heat. Stir in 3/4 cup cheese, thyme, salt and pepper.
• Combine breadcrumbs, the remaining 3/4 cup cheese and 1 tablespoon oil in a bowl.
• Layer the vegetable slices in the prepared baking dish. Pour the cheese sauce over the top and top with the breadcrumb mixture.
• Bake the gratin until it is bubbling and the top is golden, 30 to 40 minutes. Let cool for 10 minutes before serving.
• Tips: Beets, carrots and parsnips are easily peeled with a vegetable peeler, but for tougher-skinned roots like celeriac, rutabaga and turnips, removing the peel with a knife can be easier. Cut off one end of the root to create a flat surface to keep it steady on the cutting board. Follow the contour of the vegetable with your knife. If you use a vegetable peeler on the tougher roots, peel around each vegetable at least three times to ensure all the fibrous skin has been removed.
• To make fresh breadcrumbs, trim crusts from country-style whole-wheat bread. Tear bread into pieces and process in a food processor until coarse crumbs form. One slice of bread makes about 1/2 cup crumbs.
