Celeriac Fennel 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.

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.

POTATO-FENNEL GRATIN

Steps:

• Preheat the oven to 350 degrees F.
• Butter the inside of a 10-by-15-by-2-inch (10-cup) baking dish.
• Remove the stalks from the fennel and cut the bulbs in half lengthwise. Remove the cores and thinly slice the bulbs crosswise, making approximately 4 cups of sliced fennel. Saute the fennel and onions in the olive oil and butter on medium-low heat for 15 minutes, until tender.
• Peel the potatoes, then thinly slice them by hand or with a mandoline. Mix the sliced potatoes in a large bowl with 2 cups of cream, 2 cups of Gruyère, salt, and pepper. Add the sauteed fennel and onion and mix well.
• Pour the potatoes into the baking dish. Press down to smooth the potatoes. Combine the remaining 2 tablespoons of cream and 1/2 cup of Gruyère and sprinkle on the top. Bake for 1 1/2 hours, until the potatoes are very tender and the top is browned and bubbly. Allow to set for 10 minutes and serve.

POTATO & CELERY ROOT GRATIN WITH LEEKS

Steps:

• Preheat oven to 350°F. Heat cream, garlic, and thyme sprig in a medium saucepan just until bubbles begin to form around edge of pan. Remove from heat; set aside to steep.
• Melt 1 tablespoon butter in a medium skillet over medium heat. Add leeks; season with salt and cook, stirring often, until tender (do not brown), 10-12 minutes. Transfer to a small bowl and set aside.
• Butter a 3-quart gratin dish with remaining 1 tablespoon butter. Layer 1/3 of potato slices and 1/3 of celery root slices evenly over bottom of baking dish. Cover with 1/3 of leeks, then 1/3 of Gruyère. Sprinkle with salt, pepper, and 1 teaspoon thyme leaves. Repeat layers twice more. Strain cream mixture into a medium pitcher and pour over vegetables.
• Set gratin dish on a large rimmed baking sheet and cover tightly with foil. Bake for 1 hour. Carefully remove foil; continue baking until top is golden brown and sauce is bubbling, 25-30 minutes. DO AHEAD: Can be made 2 hours ahead. Let stand at room temperature. Tent with foil and rewarm in a 300° oven until hot, about 20 minutes.

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.
