ROOT VEGETABLE GRATIN

Steps:

• Preheat the oven to 350 degrees. Butter a 13-by-10-by-2 1/2-inch oval 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.

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 the oven to 350 degrees F. Spray a 9 by 9-inch baking dish with cooking spray.

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.

Return to the oven, and bake another 30 to 45 minutes, stirring or pressing the vegetables down with the back of your spoon every 10 minutes until the gratin is nicely browned and most of the liquid is absorbed.

• Preheat the oven to 180C/gas 4/fan 160C and butter a shallow ovenproof dish. Layer the potatoes, then the parsnip in the bottom of the dish with two of the sliced garlic cloves and sprinkle over a little salt and half the rosemary.
