Cheesy Root Vegetable Gratin Recipes

CHEESY ROOT VEGETABLE GRATIN

Steps:

• Preheat oven to 400˚F. Grease a 3 quart baking dish with butter.
• Slice sweet potato, parsnips and beets into very thin rounds (using a mandoline is easiest) and transfer each vegetable to its own bowl.
• Pour 4 tablespoons cream over each sweet potatoes and parsnips, and 2 tablespoons cream over beets. Top each bowl of sliced vegetables with ½ ounce grated Parmesan and 1 teaspoon minced thyme. Season each bowl generously with salt and pepper and toss together until all vegetable slices are well coated.
• Pour remaining 1/4 cup cream into the bottom of a 3 quart (oval) baking dish and sprinkle with ½ ounce of Parmesan and minced garlic.
• Grab a stack of sweet potatoes and line them standing up on a bias, at the top of the baking dish. Follow the sweet potato with a row of parsnips, followed by a row of beets. Repeat with the remaining sweet potatoes, parsnips and beets, creating 6 rows of root vegetables.
• Season top of gratin with salt, pepper and sprinkle of remaining Parmesan.
• Cover with foil and bake for 30 minutes or until vegetables are soft.
• Uncover gratin and top with shredded gruyere.
• Place gratin back into oven, uncovered, and continue to bake for an additional 18 to 20 minutes or until vegetables are fork tender, cheese has melted and the top has lightly browned.
• Finish with a sprinkle of fresh thyme leaves. Serve.

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.

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.
