Winter Celeriac Gratin Food

WINTER CELERIAC GRATIN

Steps:

• Preheat the oven to 200C/180C Fan/Gas 6.
• In a large bowl, mix the potato, shallots, parsley, celeriac and ham, if using. Add the capers and season with pepper and a pinch of salt. Tip the mixture into an ovenproof dish (approximately 30cm/12in square and not too deep).
• Heat the crème fraîche and milk in a small pan. Stir in the mustard and garlic and season with half a teaspoon flaky sea salt and pepper. Bring to a gentle boil, then pour over the gratin. It won't cover the vegetables - that's fine.
• Bake for 1 hour 15 minutes, or until the vegetables are tender. Cover the top with foil if it is getting too brown. Leave to sit for 5 minutes before serving.

CHEESY CELERIAC, LEEK & ROSEMARY GRATIN

Steps:

• Heat the butter in a saucepan. Add the leeks, rosemary and bay leaf, then cover and cook very gently over a medium-low heat for 15-20 mins until the leeks are soft. Pour over the milk and almost all of the cream, then season and bring to the boil. Remove from the heat and leave to cool a little, then scoop out the bay leaf.
• Pour a little of the leek mixture into an ovenproof gratin dish. Arrange a layer of celeriac in the dish, then season. Spoon over some more of the leek mixture and scatter with a little cheese. Repeat the process, alternating between layers of the leek mixture, cheese and celeriac slices, then finish with a drizzle of cream and the last of the cheese. Can be prepared up to a day ahead and kept in the fridge.
• Heat oven to 180C/160C fan/gas 4. Bake the gratin for 1 hr-1 hr 15 mins until the top is golden and the celeriac is tender when poked with a knife. If the gratin is browning a little too much, cover the dish in foil. Can be chilled, then reheated in a microwave or oven on a low heat with a drizzle more cream.

CELERIAC GRATIN

Steps:

• Heat oven to 400 degrees. Butter a 1 1/2-quart gratin dish. Scatter shallots over bottom of dish. Trim celeriac by cutting off bottom and top, then cutting off thick outer layer with a sharp knife. Cut into 1/4-inch slices and then julienne. Arrange evenly in gratin dish. Sprinkle thyme leaves over celeriac.
• In a small bowl, whisk together cream, mustard, nutmeg, and salt and pepper. Pour over celeriac and sprinkle with cheeses. Cover with foil and bake for 20 minutes.
• Remove foil and continue baking until top is brown and bubbly and cream is thickened and reduced, about 20 more minutes. Let cool for 10 minutes and 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.

CELERY GRATIN

Steps:

• Preheat oven to 375°. In a large saucepan, melt 6 tablespoons butter over medium heat. Stir in flour until smooth; gradually whisk in milk and cream. Bring to a boil, stirring constantly; cook and stir until thickened, 3-4 minutes. Stir in cheese, salt, pepper and nutmeg until combined. Stir in celery and leaves; transfer to a greased 13x9-in. baking dish., Tear bread into pieces and place in a food processor or blender. Cover and pulse until crumbs form. Transfer to a large bowl. Melt remaining 2 tablespoons butter. Drizzle over bread crumbs; toss to coat. Sprinkle over celery mixture., Bake until bubbly and topping is golden brown, 25-30 minutes. If desired, sprinkle with additional celery leaves.

CELERIAC GRATIN WITH BLUE CHEESE AND BACON

Steps:

• Preheat the oven to 180C/350°F Peel and quarter the celeriac, and cut it into 1/4in slices. Cut the parsnips into 1/4in slices, too. Butter a gratin dish around 10in x 7in x 2.5in in size. Put half the celeriac in an overlapping layer in the bottom, sprinkle on a little salt, pepper, a few grinds of nutmeg and some thyme.
• Dot with a few scraps of butter, then add the parsnips in one layer and season as with the celeriac. Top with another layer of celeriac. Pour over the broth and cream, and cover tightly with foil. Bake for 40 minutes, until the vegetables are tender and most of the liquid has been absorbed. If it's still a little soupy, uncover and bake until most of the broth has evaporated.
• While the vegetables are cooking, fry the bacon in a dry pan until just crisp. Cool and toss in a bowl with the cheese. Scatter this over the top of the gratin, turn up the heat to 200C/400F, and cook for a further 15 minutes, until the top is golden and bubbling.

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.
