Creamy Onion Tart Recipes

CREAMY ONION TART

Steps:

• Put all the pastry ingredients into the bowl of a food processor, then whizz briefly until the mixture resembles fine breadcrumbs. Remove the lid, add 2 tbsp cold water, then whizz again until everything starts to stick together. Tip the pastry onto a lightly floured surface and knead briefly until smooth. Roll out thinly, then use to line a lightly greased 23cm diameter, 3-4cm deep loose-bottomed flan tin. Prick the base with a fork, then transfer to the fridge to chill for 20 minutes.
• Meanwhile, make the filling. Melt the goose fat or butter in a large, shallow pan with a lid, then add the onions and cook gently, covered, for 10 minutes. Remove the lid and raise the heat slightly, then cook for another 20 minutes, stirring often, until very soft and just beginning to colour. Season lightly, then transfer to a large mixing bowl and set aside.
• Put a heavy-duty baking sheet into the oven and preheat to 200°C/fan 180°C/gas 6. Line the chilled pastry case with a crumpled sheet of baking paper, then a thin layer of baking beans or rice. Slide the flan tin onto the hot baking sheet and bake for 15-20 minutes until the pastry is biscuit-coloured around the edges. Remove the paper and beans/ricethen return to the oven for 5-7 minutes until the base and sides are crisp and golden. Remove from the oven and set aside, then lower the heat to 190°C/fan170°C/gas 5.
• In a mixing bowl, beat the eggs with the nutmeg and cream or crème fraîche, season to taste, then stir into the bowl of cooled onions. Pour the mixture into the pastry case, using a spoon to evenly distribute the onions, then slide the flan tin back onto the hot baking sheet and cook for 25-30 minutes until the filling is set and lightly golden. Leave to cool slightly before removing from the tin and cutting into slices to serve.

VIDALIA ONION TART

Steps:

• Preheat oven to 375 degrees F (190 degrees C.)
• In a large heavy skillet, saute butter and diced Vidalia onion. Cook until lightly caramelized. Remove from heat and whisk in sour cream. Slowly whisk in evaporated milk. Whisk in dry soup mix until completely incorporated. Whisk in eggs. Mix in the shredded cheese until blended. Spoon mixture into an unbaked pastry. Place pie on a cookie sheet and place into oven.
• Bake in preheated oven 40 to 45 minutes; or until a knife inserted comes out clean. Let stand 10 to 15 minutes.

ULTIMATE ONION TART

Steps:

• Heat oven to 190C/fan 170C/gas 5. Roll out the pastry on a lightly floured surface and use to line a deep 23cm fluted flan tin. Line with baking paper and fill with baking beans. Bake blind for 15 mins.
• Heat the butter and oil in a large frying pan, then gently fry the onions, covered, for about 30 mins until completely softened, but still pale in colour.
• Beat the eggs and cream together in a bowl, then add the cheese and some seasoning. Stir in the onions, then spoon the mixture into the flan case. Bake for 25-30 mins until lightly set and browned.

CREAMY ONION TART

Steps:

• Preheat the oven to 325°F (163°C).
• In a large skillet, combine the onion, 2 tablespoons of the butter, and a generous pinch of salt. Cover and cook, stirring occasionally, over medium-low heat until very tender and pale gold, about 25 minutes.
• In a large saucepan, melt the remaining 2 tablespoons butter over medium-low heat. Add the flour and cook, whisking constantly, until the mixture smells nutty, about 2 minutes. Whisk in the milk and cream in a slow, steady stream. Still whisking, bring to a boil and cook for 2 minutes. Remove from the heat and let cool slightly, whisking occasionally.
• Pour a little of the cream mixture into the eggs, whisking until completely combined. Slowly whisk this mixture back into the cream mixture in the saucepan, a little at a time, until well incorporated and smooth. Stir in the caramelized onions, then season to taste with salt, pepper, and nutmeg. Spoon the mixture onto the pate brisee, spreading it evenly.
• Bake the tart until golden brown and a knife inserted in the center comes out clean, about 1 hour. Let the tart cool in the pan on a wire rack for 20 minutes, then unmold. Slice and serve warm.

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.
