Celeriac And Sweet Potato Gratin Recipes

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 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.

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.

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.

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.

Steps:

• Preheat the oven to 170 C, 150 C fan, 325 F, gas 3. Place a layer of celeriac at the bottom of a baking dish and season with the celery salt and freshly ground black pepper.
• Cover with a layer of sweet potato and scatter with a few sliced onions. Repeat until all the vegetables are used, finishing with a layer of sweet potato and onion.
• Scatter the cheese over the top, pour over the stock and bake for 35 to 40 minutes or until the vegetables are soft.

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, 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.
