Sweet Potato And Celeriac Au Gratin Recipes

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 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.

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.
