Apple Onion Tarts Recipes

Steps:

• Heat oil and butter in a large skillet over medium-high heat. Add apples and onions, and cook until golden brown, about 15 minutes. Cover, reduce heat to low, and cook until very soft and caramelized, about 35 minutes. Add vinegar and salt, and cook 5 minutes. Let cool.
• On a lightly floured surface, roll out dough to a generous 1/8 inch thick. Cut out six 7-inch rounds, gathering scraps and rerolling dough if needed. Place on parchment-lined baking sheets.
• Puree half the apple-onion mixture in a food processor until smooth. Using an offset spatula, spread 3 tablespoons apple-onion puree over each dough round, leaving a 1-inch border around edges. Sprinkle each with 2 tablespoons cheese. Season with pepper. Top each with a generous tablespoon of remaining apple-onion mixture, and sprinkle with 2 teaspoons cheese. Fold edges of dough in, crimping with your fingers. Refrigerate until chilled, about 30 minutes. Meanwhile, preheat oven to 350 degrees.
• Bake until edges are golden brown, 40 to 45 minutes. Serve tarts warm or at room temperature.

Steps:

• Preheat the oven to 400 degrees. Line 2 sheet pans with parchment paper.
• Cut each sheet of puff pastry into 4 squares. Divide the pastry between the prepared sheet pans and refrigerate while you prepare the apples.
• Peel the apples and cut them in half through the stem. Remove the stems and cores with a sharp knife and a melon baller. Slice the apples crosswise in 1/4-inch-thick slices. Place overlapping slices of apples diagonally across the pastry and place one slice of apple on each side of the arranged slices. Sprinkle the apples evenly with the sugar and dot them with the butter.
• Bake for 40 minutes, until the pastry is browned and the edges of the apples start to brown. Don't worry! The apple juices will burn in the pan but the tarts will be fine! When the tarts are done, heat the apricot jelly together with the Calvados until bubbly and brush the apples and pastry completely with the jelly mixture. Loosen the tarts with a metal spatula so they don't stick to the paper. Allow to cool and serve warm or at room temperature.

Steps:

• Heat oven to 400º F. Heat the oil in a large skillet over medium heat. Add the onions and cook, stirring occasionally, until soft and golden brown, 12 to 15 minutes. Stir in the apples, ½ teaspoon salt, and ¼ teaspoon pepper and cook until just tender, 2 minutes.
• Place each sheet of pastry on a parchment-lined baking sheet and prick all over with a fork. Spread with the crème fraîche, leaving a ½-inch border. Top with the onion mixture and bake until the pastry is crisp and browned, 30 to 35 minutes. Cut into pieces before serving.

Steps:

• Heat oven to 200C/180C fan/gas 6. Unroll the pastry sheet onto a large baking tray (leave it on the paper from the pack). If the edges are not straight, trim them with a sharp knife. Score a border, about 1cm in from the edge. Score a criss-cross pattern over the central piece of pastry (this will prevent it from rising too much) and around the border, if you like. Bake for 15 mins.
• Meanwhile, heat the oil in a large pan. Add the onions and cook for 10-15 mins until softened and starting to caramelise. Stir in the vinegar, bubble for 1 min more, then add the Dijon mustard and thyme, season well and set aside. Slice the apple thinly through the core so a few slices have a nice star in the middle, and remove any seeds. Toss the slices in a splash of vinegar to prevent them from browning.
• The pastry should be puffed and starting to colour. Push down the centre, then spread over the onions. Add blobs of cranberry sauce, then top with the apple slices and brie, overlapping them to cover the tart. Add a few more thyme sprigs, drizzle with a little oil, then put back in the oven for a further 25 mins until the cheese is bubbling and the apple slices are soft. Serve warm or cold.

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.
