Potato Beetroot And Sweet Potato Gratin Recipes

Steps:

• If you have a gas burner, roast the poblano peppers over the open flame, turning occasionally with tongs, until the peppers are well charred all over, about 4 minutes. If you do not have a gas burner, halve the peppers lengthwise, place them in a baking pan and broil them in a preheated broiler, skin-side up, until well charred. Place the charred peppers in a bowl and cover with plastic wrap for 10 minutes. Peel, stem and deseed the peppers, then cut into strips.
• Preheat the oven to 400 degrees F. Butter a 9-by-13-inch baking dish.
• Stir together the cream, salt, lime zest, cumin and garlic in a bowl.
• Peel the sweet potatoes and russet potatoes and thinly slice them with a mandoline (about 1/4-inch thick).
• Arrange half of the russet potatoes in the buttered baking dish. Top with half of the sliced poblanos, then half of the sweet potatoes. Top with half of the cream mixture and 1/3 cup Cotija. Repeat with the remaining ingredients (potatoes, poblanos, sweet potatoes, cream and the remaining 2/3 cups Cotija) and press down firmly to submerge the potatoes as much as possible.
• Cover the baking dish tightly with foil and bake for 35 minutes. Uncover and continue to bake until the potatoes are tender, the liquid has absorbed, and the top is browned in spots, 25 to 30 minutes more.
• Let stand 10 minutes before serving.

Steps:

• Pre-heat oven to 200°C.
• Layer half the sliced potatoes over the bottom of a 2 litre capacity (8 cup) ceramic baking dish. Drizzle with a little of the olive oil, sprinkle with a little thyme and season lightly.
• Cover with the beetroot and season as before. Repeat with the sweet potato and finally remaining potato. Pour cream over the layered vegetables and sprinkle with combined cheeses.
• Cover gratin with a layer of baking paper and wrap with foil.
• Bake in preheated oven 60-70 minutes or until a skewer passes through the vegetables without resistance.
• Remove foil and paper and bake further 20-30 minutes or until top is golden.
• Tip: You can speed up the baking by pre-cooking the unpeeled veggies for a couple of minutes in the microwave.

Steps:

• Preheat the oven to 350°F. Butter a 3-quart casserole.
• To blanch the turnips, bring a large pot of water to the boil. Add the sliced turnips and cook 5 minutes. Remove them and drain thoroughly in a strainer.
• Gently combine the turnips and sweet potatoes. Place a layer of the vegetables in the casserole and dot with half the butter. Sprinkle generously with tarragon, salt, and pepper, and cover with half of the Parmesan. Make another layer. Top with the bread crumbs and pour the cream around the sides. Dot with the remaining butter and Parmesan. Bake until the vegetables are soft but not mushy, 1 to 1 1/2 hours.
• The gratin can be made ahead several days, or frozen for up to 3 months. Let defrost in the refrigerator and reheat for 30 to 45 minutes in the oven, or reheat in the microwave.
• Variation
• Omit the sweet potatoes and double the amount of turnips.

Steps:

• Place potatoes in a greased 8-in. square baking dish. In a bowl, beat egg. Add cream, salt, nutmeg and pepper; mix well. Pour over potatoes; sprinkle with cheese. Bake, uncovered, at 375° until the potatoes are tender, 40-45 minutes. If desired, top with fresh thyme to serve.

Steps:

• Preheat the oven to 190c/fan170c/gas 5.
• Put the cream garlic and thyme over a medium heat. Bring to a simmer, then remove from the heat and allow to infuse for 10 minutes.
• Pass through a sieve and set aside, discarding the garlic and thyme.
• Slice the potatoes and beetroot to about 2mm thick use a mandolin if you have one.Pour a thin layer of cream into the bottom of a fairly deep 2 litre oven proof dish.Layer half the potatoes on top of the cream, pour over more cream and season to taste. Add all the beetroot in 1 layer.Add more cream, season, then top with the remaining potatoes. Pour over the remaining cream and season.
• Bake for 50-55 mins or until bubbling, golden and tender - a knife should go through without resistance.

Steps:

• Preheat oven to 190 degrees C, Gas mark 5. Put cream garlic and thyme in saucepan and bring to a slow simmer over medium heat. Let garlic and thyme infuse about 10 minutes, pass through a sieve into a jug and set aside. Discard garlic and thyme.
• Slice potatoes and beetroot as thin as possible (a mandolin is good for this, or the slicing blade on a food processor).
• Pour a thin layer of cream into a deep 2 litre dish. (I use a souffle dish). Layer half the potatoes on top of the cream. Pour over more cream and season with salt and pepper. Add all the beetroot in 1 layer. Add more cream, season, and top with the rest of the potatoes. Pour over remaining cream and season one last time.
• Bake in preheated oven 30-35 minutes or until golden and bubbling and top layer has just crisped up. (You may need to cover with foil halfway through cooking time to prevent top layer burning).
