ROOT VEGETABLE GRATIN

Steps:

• Preheat the oven to 350 degrees F. Butter a 13-by-10-by-2 1/2-inch baking dish.
• Heat 2 tablespoons of olive oil in a large (12-inch) saute pan over medium heat, add the onion and fennel and cook for 10 minutes, tossing occasionally, until lightly browned and tender. Add the garlic and cook for one minute.
• Meanwhile, in a large bowl, combine the onion mixture, sweet potatoes, celery root, Yukon Gold potatoes, cream, chicken stock, Gruyere, thyme, 1 tablespoon salt and 1 1/2 teaspoons pepper. Pour the mixture into the prepared baking dish and press lightly so the vegetables lie flat all the way to the edge. Combine the bread crumbs and 2 tablespoons of olive oil and distribute evenly on top. Bake uncovered for 1 1/2 hours, until the vegetables are very tender when tested with a small knife and the top is browned and bubbly. Allow to set for 15 minutes and serve hot.
• Make ahead: Bake in advance and reheat while the turkey rests, or assemble the dish, cover and refrigerate for up to 24 hours, then bake before serving.

Steps:

• Preheat the oven to 375 degrees F. Spray a 9-by-13-inch baking dish with nonstick cooking spray.
• Combine the heavy whipping cream, chicken stock, butter, thyme, garlic and Parmesan rind in a small saucepot. Place over medium-low heat and cook just until simmering, 10 to 12 minutes. Turn off the heat and whisk in the flour. Strain the cream mixture through a colander into a container with a pour spout and discard the thyme stems, garlic and cheese rind.
• Spread the potato rounds in an even layer in the bottom of the prepared baking dish. Pour a third of the cream mixture over the potatoes. Sprinkle with 1/2 teaspoon salt, 1/4 teaspoon pepper and 1/2 cup grated cheese. Next, shingle half the carrots and parsnips in alternating rows in an even layer. Pour a third of the cream mixture over the top, then sprinkle with salt, pepper and 1/2 cup cheese. Finally, shingle the remaining parsnips and carrots in alternating rows in an even layer. Use your hands to lightly press down on the vegetables to even out, if needed. Pour the remainder of the cream mixture over the top, then sprinkle with salt and pepper. Reserve the remaining cheese (about 1 cup).
• Cover the baking dish tightly with aluminum foil and bake until the vegetables are fairly tender and the sauce is simmering, about 1 hour. Remove the foil and sprinkle the top of the gratin with the remaining cheese. Bake, uncovered, until the cheese is lightly browned and the vegetables are tender, another 30 minutes.
• Cool for at least 10 minutes before slicing. Serve warm.

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.
