Best 7 Sweet Potato And Root Vegetable Gratin Recipes

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.

ROOT VEGETABLE GRATIN

Steps:

• Preheat the oven to 400 degrees. Butter a 2-quart gratin or baking dish. Place the sliced vegetables in a large bowl, and season generously with salt and pepper. Add the thyme, and toss together.
• Arrange the vegetables in the gratin dish. Add the milk, season with more salt and pepper if you wish, and place in the oven on the middle rack. Bake 45 minutes; every 15 minutes, press the vegetables down into the milk with the back of your spoon.
• Add the cheese, and stir in carefully to incorporate. 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. Remove from the heat and serve, or allow to settle and serve warm. (You can make this several hours ahead of serving, and reheat in a medium oven.)

ROOT VEGETABLE GRATIN

Steps:

• Put oven rack in upper third of oven and preheat oven to 400°F.
• Peel parsnips and cut crosswise into 3-inch lengths with a knife, then cut lengthwise around core into 1/8-inch-thick slices with slicer (discard core). Transfer to a large bowl.
• Peel celery root and all potatoes (prepare russet potatoes last to avoid discoloration) and halve lengthwise, then cut crosswise into 1/8-inch-thick slices with slicer. Add to parsnips along with salt, garlic, pepper, nutmeg, broth, and 1 3/4 cups cream, tossing to combine. Transfer to gratin dish, spreading evenly.
• Cut out a piece of parchment or wax paper to fit just inside gratin dish, then butter 1 side of parchment. Cover vegetables directly with parchment, buttered side down, then put dish in a shallow baking pan (to catch any drips). Bake until gratin is bubbling all over and vegetables are tender when pierced with a knife, about 50 minutes. Discard parchment.
• Just before serving, preheat broiler. Drizzle top of gratin with remaining 2 tablespoons cream and broil 4 to 6 inches from heat until browned, 2 to 3 minutes.

ROOT VEGETABLE GRATIN FROM REYNOLDS WRAP®

Steps:

• Preheat oven to 350 degrees F. Line a baking sheet with two long sheets of Reynolds Wrap® Aluminum Foil, overlapping them in opposing directions so you make a cross, with plenty of foil at each end to eventually fold over into the center. Lightly spray with cooking spray and set aside.
• In a large mixing bowl, stir together cream, shallot and garlic. Add parsnips, sweet potato and turnip and carefully toss together until all the pieces are well coated. In another mixing bowl combine 1 cup of the grated cheese, green onion, and thyme and toss together.
• To assemble, place a single layer of cream-coated root vegetable pieces onto the foil-lined baking sheet and season generously with salt and pepper. Sprinkle 1/4 of the cheese mixture over the surface. Repeat with another layer of vegetables, salt and pepper and cheese mixture and continue with this pattern until all the ingredients have been used (finishing with a layer of vegetables).
• Bring each side of the excess foil hanging over the baking sheet together and seal tightly, leaving room for heat circulation inside. Bake gratin in the oven for 40 to 45 minutes or until vegetables are fork tender. Open foil carefully by cutting along top fold with a sharp knife, allowing steam to escape; then open top of foil.
• Uncover gratin and sprinkle remaining cheese over the top. Place gratin under a broiler and broil for 30 seconds to 1 minute or until cheese has melted and the top has browned slightly. Allow gratin to cool for about 10 minutes before cutting up and serving.
