Celeriac Gratin Recipes

SLOW-COOKED DUCK LEGS IN PORT WITH CELERIAC GRATIN

Steps:

• Heat oven to 160C/140C fan/gas 3. Put the duck legs in a flameproof casserole set over a medium heat. Brown all over, then remove from the casserole and set aside. Pour off all but 1 tbsp of the fat, leave more fat in the pan if you are doubling or tripling (save the drained fat for your Christmas roasties). Add the carrots and onion to the casserole and cook for 5-10 mins or until starting to caramelise. Stir in the flour and cook for 1 min more. Return the duck along with the remaining ingredients. Bring to a simmer, then cover with a lid and put in the oven for 2 hrs.
• Meanwhile, prepare the gratin. Put the milk, cream, garlic and rosemary in a pan set over a low heat. Bring to a gentle simmer for 5 mins, then remove from the heat and leave to infuse for 30 mins. Grease 2 ramekins (about 8cm diameter, 5cm deep). Arrange the celeriac and potato slices in the ramekins, seasoning the layers as you go. Remove the garlic and rosemary from the milk, pour over the veg, then dot with butter. Cover tightly with foil and bake with the duck for 1½ hrs.
• Once cooked, remove the duck and gratins from the oven. To freeze the duck, cool, then pack into a freezer container, pushing the duck under the sauce. If it doesn't cover it, lay cling film on top. Use within 2 months. Thaw in the fridge, then reheat in the casserole and complete from Step 4. Increase oven to 220C/200C fan/gas 7. Put a heavy can on top of each foil-wrapped gratin and stand for 15-20 mins, or chill like this until needed. Once pressed, turn the gratins out onto a baking tray, sprinkle with a little Parmesan and bake for 20 mins until golden.
• Meanwhile, remove the duck legs from the casserole, strain the cooking liquid into a clean pan and bring to a rapid boil. Reduce the sauce by half until thickened and glossy. Add the duck legs and heat through. Put a duck leg on each plate with a little sauce spooned over the top. Serve with the gratins and seasonal veg.

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.
