Gratin Of Sweet Potato And Celeriac Food

SWEET POTATO AND CELERIAC AU GRATIN

Steps:

• Pre-heat oven to 350 F.
• Peel and slice your celeriac and sweet potatoes, with a mandolin. Make two separate piles. Then, separate each pile into 4 piles. You should now have 8 piles, all about the same size.
• Butter the inside of a baking pan (I used a 9"x9" square).
• Start by placing a thin, consistent layer of celeriac slices. It should entirely cover the bottom of the pan. Sprinkle a small amount of salt on the layer. Next, add a thin, consistent layer of sweet potatoes. Make sure your layers are even and not thicker in the middle. Season with a little salt and pepper. Drizzle 1/4 cup of cream fairly evenly around the layer. Sprinkle 1/4 cup of grated parmesan cheese over the sweet potatoes. Finally, give a light dust of nutmeg. Repeat these steps, alternating layers and seasoning each layer with a little salt, pepper, nutmeg and a bit of cream and parmesan. When done, top with the final 1/4 cup of cream and a 1/2 cup of parmesan cheese.
• Place your pan, uncovered, in the oven and allow to bake for about 45 minutes. When a knife can be entered easily into the center of the dish, it is ready. If it gets prematurely dark, feel free to cover with a bit of aluminum foil, but be sure to poke some holes in it. It may take a bit more than an hour, depending on how thick you made it, but it will get there.
• When done, remove it from the oven and allow it to sit for 15 minutes, before slicing. This will allow it to firm up, a bit.

SWEET POTATO AND CELERIAC GRATIN

Steps:

• Preheat the oven to 200°C/180°C fan/400°F/ gas mark 6.
• Peel and thinly slice the vegetables (I do this in my food processor to save time).
• Scatter a third of the vegetables in the ovenproof dish. Top with a third of the garlic and thyme, ¼ tsp salt and lots of freshly ground pepper. Then add half the bacon and half the walnuts.
• Repeat step 3. Then top with the remaining vegetables, garlic, thyme, ¼ tsp salt and lots of freshly ground pepper and then cover the dish in foil. Bake for an 1¼ hour or until all the vegetables are tender.
• Remove the foil and pour the cream over the top of the gratin. Put back in the oven for 30 minutes or until the top is lightly browned.

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.

CELERIAC & POTATO GRATIN

Steps:

• Heat oven to 180C/160C fan/gas 4 and grease a shallow ovenproof dish about 35 x 24cm. Melt the butter in a non-stick frying pan, add the onions and fry for 10 mins, stirring frequently, until soft and starting to turn golden. Sprinkle over some seasoning and the sugar, stir again, then cook 5-10 mins more until golden. Meanwhile, heat the milk with the nutmeg, garlic, thyme and seasoning. When the mixture starts to boil, pour in the cream and turn off the heat.
• Quarter the celeriac and thinly slice, then arrange in the base of the dish. Pour over half the milk mixture, then spoon over the golden onions. Thinly slice the ends of the potatoes, reserving the middles. Pile the sliced potatoes into the dish, then thinly slice the reserved middle sections and arrange neatly on top. (By cutting the potatoes this way, you should have neat slices roughly all the same size for the top of the gratin.) Pour over the remaining milk mixture, scatter over the Parmesan and bake for 1 hr 30 mins until a knife easily cuts through the layers. Allow to rest for 10 mins before serving to allow the creamy sauce to soak into the potatoes.

SWEET POTATO AND GRUYèRE GRATIN

Steps:

• Heat oven to 400 degrees and generously butter a 9-by-13-inch baking pan or shallow gratin dish. Butter a piece of foil large enough to cover top of pan. Sprinkle Parmesan all over bottom of pan.
• In a medium pot, bring cream, sage, rosemary, garlic, nutmeg and a pinch of salt to a simmer. Simmer until reduced by 1/4, about 10 minutes.
• In a large, heatproof bowl, whisk eggs just enough to break them up. Slowly pour hot cream into eggs to combine, whisking while pouring, and reserve the mixture.
• Meanwhile, using a mandoline or sharp knife, slice the potatoes into 1/8-inch-thick rounds.
• Place 1 layer of potatoes in the pan, slightly overlapping as you go, using about a third of the slices. Sprinkle with 1/4 teaspoon salt and pepper to taste, then pour 1/3 of the egg mixture over potatoes. Top with 1/2 cup Gruyère. Repeat with another layer of potatoes, 1/2 teaspoon of salt, pepper and 1/3 egg mixture. Top with 1/2 cup Gruyère. Top with remaining potatoes, 1/4 teaspoon salt, pepper to taste, and remaining egg mixture (but not the remaining cheese). Press down to compact the potatoes. Cover with foil and bake until potatoes are tender, about 40 minutes, then remove foil, sprinkle top with remaining 2/3 cup Gruyère and bake until browned and bubbling, 25 to 30 minutes. Let cool slightly, then serve.

CELERIAC AND SWEET POTATO GRATIN

Steps:

• Pre-heat the oven to 450 degrees.
• Coat an oven safe casseraole dish with non-stick spray.
• Arrange a layer of sweet potatoes, slightly overlapping. Sprinkle about a TB of flour on the potatoes, followed by salt and pepper, tarragon, 1 tb of butter (cut into small pieces)and 1 TB of cheddar.
• Repeat this process with the onions and celeriac, topping each layer with flour, butter, seasonings and cheese.
• Complete the gratin with a layer of sweet potatoes. Pour the cup of cream over the top of the casserole (slowly so it doesn't overflow). When it has sunk into the layers, season the top of the casserole, cover with tinfoil and bake until the vegetables are tender (about 45 minutes).
• Cover the gratin with the remaining cheddar cheese and return to the oven uncovered for an additonal 5 - 10 minutes so the cheese can melt.

SWEET POTATO GRATIN

Steps:

• Preheat oven to 375 degrees. Pour 1 cup cream into a large ovenproof skillet. Arrange sweet potatoes evenly in pan, season with salt and pepper, and pour remaining cream on top. Gently press on potatoes to submerge. Bring to a simmer over medium, transfer to oven, and bake 12 minutes. Press on potatoes to submerge again and bake until potatoes are tender and cream is bubbling, 8 to 10 minutes more. Sprinkle with cinnamon, ginger, and cayenne. Let cool 10 minutes before serving.

SWEET POTATO GRATIN

Steps:

• Preheat the oven to 400 degrees F (200 degrees C). Grease a baking dish with cooking spray.
• Combine cream, butter, and garlic in a saucepan. Bring to a simmer; remove from heat and mix in parsley, thyme, sage, rosemary, salt, and pepper.
• Arrange 1/2 of the sweet potato slices in the prepared baking dish; cover with 1/2 of the Gruyere cheese. Pour cream mixture on top. Arrange remaining sweet potato slices over the cream. Sprinkle remaining cheese on top.
• Bake in the preheated oven until golden brown and bubbly, about 30 minutes.

CELERIAC, POTATO & ROSEMARY GRATIN

Steps:

• Heat oven to 180C/160C fan/gas 4. Grill the bacon, if using, until cooked and lightly brown, then set aside.
• Bring the cream, milk, garlic, rosemary, chilli and mustard to the boil in a medium saucepan, then turn off.
• Pour a little of the cream mixture onto the bottom of an ovenproof gratin dish. Arrange a layer of celeriac, scatter with bacon, then season. Pour over some more of the cream mixture and repeat the same process, alternating potato and celeriac, finishing with a layer of potato. Cover with the remainder of the cream mixture, then bake for 1-1¼ hrs, until golden and vegetables are tender when a knife is stuck in. Leave to sit for 5 mins, then serve.

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.

POTATOES AND CELERIAC AU GRATIN

Steps:

• Rinse the potatoes and put them in a saucepan with cold water to cover and salt. Bring to a boil and simmer for 15 minutes. They will not be fully cooked. Drain the potatoes and when they are cool enough to handle, peel and cut them into half-inch slices.
• Pare the celery knob, cut it into quarter-inch slices and put them in a saucepan with water to cover. Add the lemon juice and salt. Bring to a boil and simmer for 10 minutes. Drain and reserve a half cup of the cooking liquid.
• Preheat the oven to 375 degrees.
• Heat the oil in a skillet. Add the garlic, tomatoes, salt, pepper and basil leaves. Cook, stirring, for one minute. Add the cream, the reserved half cup of cooking liquid, nutmeg, salt and pepper. Bring to a boil and simmer for two minutes.
• Grease an oval au gratin dish, measuring 2 1/2 by 8 by 10 inches, with butter. Arrange the potatoes in one layer. Sprinkle half of the grated cheese over the potatoes. Place the celery slices over that. Pour the tomato mixture over all and then the remaining grated cheese. Place on the bottom rack of the oven and bake 40 minutes until nicely browned.

CELERIAC, FENNEL, POTATO GRATIN

Steps:

• Mix melted butter and breadcrumbs and set aside. In the bottom of an 8x11 inch casserole dish, make one layer of potatoes. Salt and pepper. Next, layer celeriac. Salt and pepper. Sprinkle the garlic, onion, and fennel for next layer. Pour enough chicken broth to get about half way up the sides, and top with whole can of diced tomatoes. Salt and pepper. Loosely top with some tin foil and poke some holes in it so that some of the stock will evaporate and put in a 350-375 degree oven for about 45 minutes or until everything is cooked through. Remove foil and top with the breadcrumbs and continue to cook until golden brown.
