Celery Root Fennel Gratin With Gruyere Recipes

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.

GRATIN OF CELERY ROOT AND POTATO

Steps:

• Preheat the oven to 375 degrees F.
• Slice the potatoes into 1/4-inch-thick rounds. Peel the celery root and cut into 1/4-inch-thick slices to resemble the potatoes.
• Butter a heavy oval casserole dish. Layer the potatoes in the bottom of the dish, followed by the butter and then a layer of celery root. Sprinkle with sea salt. Top with a layer of half of the cheese. Repeat with the remaining potato and celery root. Top with the cream and then the remaining cheese.
• Bake until deep golden brown, about 1 hour.

CELERY ROOT GRATIN

Steps:

• Peel and coarsely chop the potatoes and the celery root. Put potatoes and celery root in separate pots and add salt to each.
• Boil the potatoes and celery root until soft, and then drain them.
• Pour the heavy cream into a pot and bring it to a boil. Add the butter, saffron, garlic, and 1 cup of the gruyere. Cook about 5 minutes over moderately low heat until the cream mixture is bright yellow.
• Puree drained celery root in food processor, gradually adding yellow cream mixture.
• Mash the drained potatoes to a rough texture.
• Add pureed celery root to mashed potatoes. Add the rest of the gruyere and mix together. Season with salt and pepper.
• Butter a 13 by 9-inch gratin dish and put the puree in it. Sprinkle with the parsley.
• Bake at 400 degrees for about 15 minutes.

FENNEL, APPLE AND CELERY ROOT GRATIN

Steps:

• Preheat oven to 375 degrees F. Butter a 2-quart gratin dish or other ovenproof casserole.
• Cut off the entire rough exterior of the celery roots, making sure that all brown parts are removed. You will be removing about 1/4 to 1/2-inch of the exterior of each. Next, cut each celery root in 1/2 lengthwise. Turn one 1/2 cut side down, and cut into 1/4-inch wide pieces. Repeat with the remaining celery root. Set aside.
• Cut off the fronds and the dark green parts of each fennel bulb, leaving just the bulb. Cut each bulb in half lengthwise. Cut each half lengthwise into 1/4-inch thick slices.
• In a vegetable steamer, combine the celery root and fennel and steam for 5 minutes. Remove from the steamer and set aside to cool slightly.
• Cut the apples into 1/4-inch-thick rings.
• Place 1/3 of the celery root on the bottom of the prepared dish. Sprinkle with salt and pepper to taste. Overlap with 1/3 of the apple slices, and sprinkle with a little more salt but no pepper. Put 1/3 of the fennel over the apples, and once again sprinkle with salt and pepper. Repeat with the remaining celery root, apple, and fennel. Pour cream around the sides of the dish until the cream reaches about halfway up the dish. Sprinkle the top of the gratin with the cheese. Cover and bake for 35 minutes, or until the vegetables and apple feel tender when pierced with a fork or a skewer. Turn the oven to broil, remove the cover, and broil until the gratin is golden brown and bubbling, about 3 minutes.
• Let cool 15 minutes to allow the cream to firm up slightly and serve.

• Butter a 3-quart gratin dish with remaining 1 tablespoon butter. Layer 1/3 of potato slices and 1/3 of celery root slices evenly over bottom of baking dish. Cover with 1/3 of leeks, then 1/3 of Gruyère. Sprinkle with salt, pepper, and 1 teaspoon thyme leaves. Repeat layers twice more. Strain cream mixture into a medium pitcher and pour over vegetables.
