Potato Celery Root Gratin With Leeks Food

POTATO & CELERY ROOT GRATIN WITH LEEKS

Steps:

• Preheat oven to 350°F. Heat cream, garlic, and thyme sprig in a medium saucepan just until bubbles begin to form around edge of pan. Remove from heat; set aside to steep.
• Melt 1 tablespoon butter in a medium skillet over medium heat. Add leeks; season with salt and cook, stirring often, until tender (do not brown), 10-12 minutes. Transfer to a small bowl and set aside.
• 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.
• Set gratin dish on a large rimmed baking sheet and cover tightly with foil. Bake for 1 hour. Carefully remove foil; continue baking until top is golden brown and sauce is bubbling, 25-30 minutes. DO AHEAD: Can be made 2 hours ahead. Let stand at room temperature. Tent with foil and rewarm in a 300° oven until hot, about 20 minutes.

CELERY ROOT AND POTATO PUREE

Steps:

• Place the potatoes in a pot large enough to accommodate the celery root and the potatoes. Add enough water to cover the vegetables by 2 inches and season generously with salt. Bring to a boil and cook for about 10 minutes. Add the celery root and cook until both vegetables are fork tender. Strain the celery root and potatoes.
• Pour the cream in a small saucepan and bring to a boil. Meanwhile, pass the celery root and potatoes through a food mill into a large bowl. Add one-quarter of the hot cream and 2 pats of the butter. Stir vigorously until the cream and butter are thoroughly combined. Repeat for the remaining cream and butter. Taste for seasoning, you will probably have to add salt. Serve in a warm serving bowl immediately or keep warm until ready to use.

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 AND POTATO PANCAKES / LATKES - GLUTEN-FREE

Steps:

• Preheat oven to 200 degrees or "warm" setting. Peel potatoes and submerge in cold water. Peel celery root with a paring knife. Pulse the onion and garlic in food processor. Mixture should be coarse, not completely pureed. Pour onion-garlic mixture into a large bowl.
• Grate the celery root using the larger grate of a box grater, or use the grater attachment of a food processor. Add to onion-garlic mixture and stir.
• Grate potatoes. Quickly squeeze a handful of grated potatoes at a time over a second bowl (or the kitchen sink) to remove all liquid. Add the dry potatoes to the onions and celery root, mixing as you go. This step should be done as quickly as possible to prevent oxidation of the potatoes.
• Heat 1/4 inch of olive oil in a large, heavy skillet (cast iron works best) over medium-high heat, until just below the smoking point.
• Add remaining ingredients to the batter, and stir until fully combined. Place a small handful of batter (approximately 1/4 cup) in the hot oil at a time. Pat each handful into a 1/2" thick pancake shape before placing in oil - This will help each latke stay together. Fry until completely golden-brown on the bottom and crispy around the outside corners. Flip and brown on the second side.
• Transfer latkes to a plate lined with paper towels or several layers of brown paper (I use grocery bags). Allow paper to absorb excess oil, then transfer latkes to a cooking rack placed over baking sheet in the preheated oven, where they will stay warm until ready to serve. Serve hot, with sour cream and applesauce.
• Extra latkes can be frozen on a baking sheet in the freezer, with parchment paper between the layers. When frozen, transfer to ziploc bags. Reheat in oven at 400 degrees F.

POTATO AND CELERY ROOT GRATIN WITH CAPER BROWN BUTTER

Steps:

• Heat the oven to 375 degrees Fahrenheit/180 degrees Celsius.
• Add 2 tablespoons/30 grams of butter and all the oil to a medium (10-inch/26-centimeter) ovenproof sauté pan over medium-high heat. Once melted, add the onions and 1/2 teaspoon salt, turn the heat down to medium-low and cook, stirring occasionally, until onions are softened and have taken on a light coloring, about 15 minutes. Add the garlic and thyme leaves, and cook for another 3 minutes, stirring occasionally, until fragrant. Stir in the miso and wine, and cook until liquid is reduced by half, about 4 more minutes. Remove from the heat.
• In a large bowl, very gently toss together celery root (celeriac), potatoes and flour with 1 1/2 teaspoons salt and a generous grind of pepper. Stir in the onion mixture to coat, then transfer everything back into the skillet, piling the vegetables haphazardly, so that the batons are pointing in different directions. Pour in the stock. Lightly grease a piece of foil with a little oil, then tightly cover the pan (oiled side down) and bake for 1 hour, or until the vegetables have cooked through.
• Remove the foil, and turn the oven temperature up to 450 degrees Fahrenheit/210 degrees Celsius. Sprinkle over the Gruyère and return the dish to the oven for 30 minutes, or until nicely browned on top, rotating the dish halfway. Leave to settle for at least 20 minutes while you make the brown butter (beurre noisette).
• Add the remaining butter and the thyme sprigs to a small saucepan, and place it over medium heat. Once melted, cook for 3 to 5 minutes, stirring occasionally, or until it starts to smell nutty (add more or less time if necessary). Add the capers (carefully, as they might spit) and cook for 4 more minutes, or until they darken and burst. Off the heat, stir 1 tablespoon lemon juice from 1 lemon, chives and another good grind of pepper.
• Pour the caper brown butter all over the top of the gratin and serve warm, with the remaining lemon sliced into wedges to squeeze alongside.

Bring cream and broth to simmer in medium saucepan. Pour over vegetables. Cover tightly with foil.
• Bake until vegetables are almost tender, about 45 minutes. Increase oven temperature to 450° F. Press potatoes with spatula to even thickness. Bake uncovered until juices thicken, about 10 minutes. Top with cheese. Bake until cheese melts and browns, about 15 minutes. Cool 15 minutes before serving.
