Best Potato Crusted Onion Tart Recipes

POTATO AND CARAMELIZED ONION TART

Steps:

• Preheat the oven to 375 degrees F.
• Prepare the pie crust according to package instructions. Flatten into a disk and chill in the refrigerator while preparing the filling.
• In a large saute pan over medium heat, heat the canola oil. Add the onions and season with salt and pepper. Cook, stirring occasionally, until the onions are dark golden brown, 10 to 15 minutes. Remove from the heat.
• In the meantime, using the slicing blade attachment of a food processor, or with a box grater, slice half the potato into 1/8-inch-thick slices. Place in cold water to avoid browning. (Reserve the remaining half of potato for another use, such as Round 2 Recipe Open Faced Roast Pork and Onion Sandwich.)
• In a small bowl, stir together the cream cheese, Italian seasoning, mustard and season with salt and pepper.
• Remove the pie crust from the fridge and roll into a 12-inch round about 1/4-inch thick. Place on a parchment-lined baking sheet. Spread the cream cheese mixture in an even layer over the pie crust, making sure to leave a 1-inch border around the edge.
• Dry the potatoes thoroughly and place an even layer on top of the cream cheese, overlapping slightly to fit and keeping 1/2-inch from the edge of the cream cheese. Over the top of the potatoes place an even layer of caramelized onions. (Reserve 1/2 cup of the onions for another use, such as Round 2 Recipe Open Faced Roast Pork and Onion Sandwich.) Fold over the edges of the crust to create a 1-inch-wide border around the tart filling.
• Bake until the crust is golden and the potatoes are cooked through, 30 to 35 minutes. Allow to cool for 5 minutes before slicing.

ONION TART

Steps:

• Blend flour and salt in the bowl of a food processor. Scatter butter over flour, top with lid and pulse 12 pulses to cut butter into flour to a coarse meal consistency.
• Dump butter-flour mixture into a medium stainless bowl. Make a well in the center and pour ice-cold water into the well.
• Using a flexible plastic dough scraper instead of your warm hands, bring the dough together by folding and pressing. Be firm and brisk and get the dough past its shaggy stage into a neat disk, trying to avoid using your hands or too much kneading. Refrigerate the dough for 30 minutes. Heat the oven to 375 degrees.
• Meanwhile, cut the onions in half and peel them. Slice the halves with the ribs (root end to sprout end direction), not against, to create julienne slices rather than half moons.
• In a wide sauté pan over medium-low heat, melt the bacon fat and slowly sweat the onions until they are caramelized. Take all the minutes you need - 25 or so - to let them soften to translucent, then to let the water they release start to evaporate, then to allow the sugars they contain to start to brown in the pan, so that you end up with soft, sweet and evenly browned onions. This is achieved by a slow caramelization. Set onions aside to cool.
• Roll tart dough out to a 1/4-inch-thick round, and drape over a round 10-inch fluted false-bottom tart pan. Lay dough into the pan, gently pressing into the bottom, and roll the pin across the pan to cut off the excess dough. Use your fingers to press the edges into the flutes, accentuating the shape of the dough edge. Dock the bottom of the dough with the tines of a fork, weight the pastry with beans or weight and blind-bake for 25 minutes.
• In a bowl, beat the egg with the cream. Stir in the caramelized onions. Season with pepper, nutmeg and salt to taste. Stir well, and make sure the onions are all evenly coated with the custard.
• Remove tart shell from oven, and slip it onto a baking sheet. Remove weights, fill with the onion-custard mixture and distribute it evenly. Return tart to oven on the sheet, and bake for 25 minutes, or until custard has set, the tops of the onions start to achieve a deeper brown and the dough is dark golden brown at the edges.
• Remove from the ring, and allow to cool just a few minutes on the rack, so that the piping hot tart shell can kind of tighten up enough to be sliced with a sharp chef's knife. (In the first few minutes straight out of the oven, the dough is kind of soft from the heat, possibly giving you the false impression that you have a soggy tart. Let it sit on the rack just to shake off this initial soft stage and to recrisp and refirm, which it will.) Cut into wedges, and serve while hot.

GOAT'S CHEESE, POTATO & ONION TART

Steps:

• Heat oven to 190C/fan 170C/gas 5. Roll out the pastry so it is large enough to fit a deep 23cm loose-bottomed tart tin, then line the tin with the pastry. Chill for 30 mins. Line the pastry with greaseproof paper, fill with baking beans and bake for 15 mins. Remove the paper and beans and return the tin to the oven for 5 mins until golden, then remove and set aside. Reduce oven to 180C/fan 160C/gas 4.
• Heat the butter and oil in a large frying pan, add the onions and potato and cook over a very gentle heat for 10-15 mins, turning occasionally, until golden and tender. Season if you want to, then add the garlic and thyme leaves, and cook for a further 3 mins. Tip into the pastry case along with the goat's cheese and spread out evenly.
• Whisk the eggs and crème fraîche together, season if you want to, then pour into the pastry case and bake for 30-35 mins until lightly golden brown and just set in the centre. Serve warm, with rocket leaves scattered over if using.

ROASTED SWEET POTATO AND ONION TART

Steps:

• Heat oven to 425°F. Spray 15x10x1-inch pan with cooking spray. In large bowl, toss sweet potatoes, onion, oil and seasoned pepper blend. Arrange mixture in single layer in pan. Roast 20 minutes, stirring after 10 minutes, just until potatoes are tender. Cool completely, about 30 minutes.
• Meanwhile, unroll pie crusts; stack on lightly greased surface. Roll into 12-inch round. Press round in bottom and up side of 10-inch deep-dish tart pan with removable bottom. Trim off excess crust along edges. Line crust with foil; fill with pie weights or dried beans. Line cookie sheet with foil. Place pan on cookie sheet.
• Bake 12 minutes. Remove weights and foil; bake 5 minutes. Cool completely on cookie sheet on cooling rack, about 15 minutes. Reduce oven temperature to 350°F.
• Stir bacon and parsley into sweet potato mixture. Spoon half of the mixture into partially baked crust; sprinkle with 1 cup of the cheese. Repeat layers once. In medium bowl, beat half-and-half, eggs, chopped rosemary and salt with whisk. Pour over cheese.
• Bake on lowest oven rack 35 to 40 minutes or until set. Cool 15 minutes. Run knife around edge of pan; carefully remove side of pan.

SAVORY POTATO TART

Steps:

• Put flour and salt in a mixing bowl (or use a food processor or a stand mixer with paddle attachment). Add half the butter and mix well, until mixture resembles coarse meal. Add remaining butter chunks and the water and mix until dough comes together. Remove dough, divide into two equal pieces and dust with flour. Quickly form each piece into a ball, then press down to make two 1-inch-thick disks. Wrap and refrigerate for at least an hour. (May be made a day in advance or frozen for up to 2 weeks.)
• Slice potatoes as thinly as possible, using a sharp knife, mandolin or food processor. Put potato slices in a large bowl and add crème fraîche, salt, pepper, nutmeg, garlic and thyme. Mix well with hands, making sure all slices are coated and seasoning is well distributed. Set aside.
• Heat oven to 425 degrees. On a well-floured surface, roll out each pastry disk to 12 1/2 inches in diameter. Line an 11-inch fluted French tart pan (with removable bottom) with one sheet of pastry, pressing in at the sides and leaving a 1-inch overlap hanging.
• Add the potatoes to the tart pan in even layers, making sure to scrape in all remaining crème fraîche with a rubber spatula. Lay the second pastry sheet on top. With a paring knife, trim excess dough and crimp the edges all around to seal. Make a few slits in the dough to allow steam to escape. Line a baking sheet with aluminum foil and set tart on it. Stir egg yolk and cream together and paint the top of the tart generously.
• Bake for 10 minutes at 425 degrees, then reduce heat to 350 degrees and bake for 1 hour more, until top is golden and potatoes are tender when probed with a paring knife. Cool slightly, then set tart pan over a small, sturdy bowl, so that the bottom of the tart pan is elevated and the fluted ring comes off. Carefully transfer tart to a plate. Serve small slices, hot or at room temperature. May be cooled completely and reheated if desired.

ONION TART

Steps:

• To make the pastry, process the flour, butter and water together in a food processor for a few minutes until a rough dough forms. Remove, wrap in plastic wrap and refrigerate for 30 minutes.
• Preheat the oven to 180°C (350°F/Gas 4).
• Roll the dough out on a floured bench and gently press into the tin. Trim the pastry to fit and reserve the left-over pastry to patch any cracks.
• To blind-bake the tart, line the pastry shell with foil and fill with baking weights or uncooked rice or beans. Bake until cooked, about 20 minutes. Remove the foil and weights and bake for an additional 15-20 minutes until lightly golden. If there are any cracks, patch with the left- over pastry.
• While the tart shell is baking, prepare the filling.
• In a large frying pan over low to medium heat, sauté the onion in the oil until very soft and light brown. This may take up to an hour. Set aside to cool slightly. Beat the egg yolks with the cream. Add the nutmeg and season well with salt and pepper. Stir the onion through the cream mixture.
• Carefully fill the pastry shell with the filling, place in the oven and bake for 40-45 minutes, or until the filling is set. Serve warm or at room temperature.

POTATO-CRUSTED GOAT CHEESE TART WITH HEIRLOOM TOMATO SALAD

Steps:

• For goat's-milk béchamel:
• Melt butter in small saucepan over medium heat. Whisk in flour. Cook 30 seconds, whisking constantly. Whisk in milk and nutmeg. Simmer until sauce thickens and comes to boil, 1 to 2 minutes. Season to taste with salt. DO AHEAD: Can be made 1 day ahead. Press plastic wrap onto surface and chill.
• For caramelized onions:
• Preheat oven to 350°F. Heat chicken fat in large ovenproof skillet over medium-high heat. Add onions; sprinkle with salt. Sauté until onions are light golden, about 14 minutes.
