Best Warm Onion Tart With Thyme Recipes

ONION AND THYME TART

Steps:

• For the pastry, sift the flour into a mixing bowl and add a pinch of salt. Add the butter and rub together with your fingertips until the mixture resembles breadcrumbs and all the butter is combined.
• Add one to two tablespoons of water and mix to bring the mixture together as a dough. If it seems too dry add another tablespoon of water. Form into a ball and flatten into a disc, wrap in clingfilm and leave it to rest in the fridge for half an hour.
• Preheat the oven to 180C/350F/Gas 4.
• For the filling, heat a large heavy-based frying pan or saucepan over a medium heat. Add the butter and, once melted, stir in the onions along with a pinch of salt. Reduce the heat to medium low and cook the onions for 20-30 minutes, or until golden-brown and completely softened. Stir them often and make sure that none burn or stick to the bottom of the pan. Stir in the thyme.
• Remove the pastry from the fridge and roll out until the thickness of a £1 coin. Grease a 20cm/8in or 23cm/9in tart tin with butter and line the tin with the pastry, pressing it into the edges. Place in the preheated oven and bake for 10 minutes. Remove, brush the base and inside edges with a little of the beaten egg, place back in the oven for five minutes and then remove.
• Mix the remaining beaten egg with the cream and cooked onions. Season with a pinch of salt and pepper. Spoon the onion mixture into the pastry case and spread evenly.
• Place back into the preheated oven and cook for 30-35 minutes, or until the filling is set but with a slight wobble when poked. Remove from the oven and leave to cool for 10 minutes before slicing into wedges and serving. This is also delicious cold.

GRUYERE & CARAMELIZED ONION TARTS

FRENCH ONION TART WITH CHEESY THYME PASTRY

Steps:

• Put the flour in the bowl of a food processor with the 100g butter. Blitz until the mixture resembles fine breadcrumbs, then add 50g of the cheese, 1 tbsp of the thyme leaves, some freshly ground black pepper and 1 tsp salt. Blitz again briefly to combine. Add 2-3 tbsp cold water, and pulse again until it comes together into a dough. If you don't have a food processor, do this in a bowl - rub the flour into the butter first, then stir in the remaining ingredients with a knife. Wrap and chill for at least 40 mins.
• Meanwhile, heat the 25g butter and the olive oil in a large frying pan over a low-medium heat, and cook the onions with a pinch of salt for 40-50 mins, stirring often, until sticky, golden and very soft when pressed with the back of a spoon. If they start to catch, reduce the heat further and add a splash of water. Be patient, as they will take a while to caramelise, but keep your eye on the pan so they don't burn.
• Stir in the vinegar, sugar and the anchovies. Keep stirring until the vinegar has evaporated, and the anchovies have dissolved into the onions. Remove from the heat.
• Heat the oven to 190C/170C fan/gas 5 and roll the pastry out onto a lightly floured work surface to a 3mm thickness. Use the pastry to line a 23cm tart tin (use the rolling pin to help you do this). Trim the edges so they're just overhanging the sides. Patch the pastry with the offcuts, if needed. Scrunch up a sheet of baking parchment, then open it out again to line the pastry, and fill with baking beans. Bake for 15 mins, remove the parchment and beans, then bake for a further 5-8 mins, or until the pastry looks dry, without any raw spots.
• Meanwhile, whisk the eggs, cream, remaining thyme and the rest of the cheese together with a pinch each of salt and black pepper. Stir in the caramelised onions. Trim the sides of the pastry using a serrated knife to neaten the edges. Pour the filling into the pastry case and tap the tin gently on the work surface to release any bubbles.
• Bake the quiche for 25-30 mins on the middle shelf of the oven until lightly golden and set in the middle, with a slight wobble. Leave to cool in the tin for at least 15-20 mins, then slice. To make the salad, whisk the olive oil and vinegar together in a bowl, then toss in the remaining ingredients. Pile the salad on top of the quiche, or serve alongside. If you like, leave the quiche to cool completely, then chill before serving. Will keep in the fridge for up to three days.

ONION TART WITH LEEKS, CAPERS AND ANCHOVY

Steps:

• Heat oven to 375 degrees.
• Put olive oil in a wide skillet or heavy-bottomed pot over medium-high heat. When oil is wavy, add onions and cook, stirring, until softened and lightly browned, about 5 to 7 minutes. Season well with salt and pepper.
• Add leeks, garlic and thyme, and cook for another 5 minutes, until leeks are softened but still bright green. Taste and adjust seasoning, then spread mixture on a baking sheet to cool to room temperature.
• Lay pastry round on a rimmed parchment-lined baking sheet. Spread cooled onion mixture over pastry, leaving a 1-inch border. Fold over the border and crimp.
• Sprinkle capers evenly over onion mixture. Arrange anchovy fillets on top.
• Bake for 45 minutes, until the pastry is nicely browned. Cool tart for 5 minutes, then sprinkle the chives on top and cut into wedges to serve.

DEBORAH MADISON'S FRAGRANT ONION TART

Steps:

• To make the filling, cut onions in half, peel them, and if they are strong, put them in a bowl of cold water. It doesn't take long for that to reduce their sting. Finely dice them.
• If you're using bacon, fry until browned and nearly crisp, then scoop out and drain on a paper towel. Throw out bacon grease, wipe out pan and add 2 tablespoons butter. When melted, add onions, thyme and 3/4 teaspoon salt. Cook over medium heat, stirring occasionally, about 25 minutes. The onions needn't be caramelized, but should just take on a faint golden hue. When done, let them cool slightly. Taste for salt (they'll be very sweet, you might want to add more) and season well with pepper.
• While onions cook, whisk eggs with crème fraîche and milk. Stir in cooled onions, cheese and bacon, if using.
• To make the crust, put flour and 1/4 teaspoon salt in the bowl of a stand mixer fitted with a paddle attachment. Add 6 tablespoons butter and turn mixer to low speed until butter has broken into small, pebble-size pieces. Drizzle in ice water until dough looks clumpy and damp. (You'll use about 3 tablespoons, fewer if butter was soft.) Form dough into a disk or a rectangle to correspond to the shape pan you're using. You have a few choices: a 9-inch tart pan, a square tart pan or a rectangular one (11 by 81/2 inches), all with removable bottoms. Wrap dough in plastic and refrigerate.
• Heat oven to 400 degrees. Roll dough to fit tart pan, then drape dough in pan. Neatly press dough into pan and shape it. Set it on a sheet pan. Pour onion mixture into tart pan, and bake until surface is golden and browned in places, 45 to 50 minutes. Let cool to warm before cutting into slices and serving.

WARM OLIVE AND CARAMELIZED ONION TART

Steps:

• Combine flours in bowl, and freeze 1 hour. Freeze butter cubes 1 hour.
• In a bowl or food processor, mix frozen flour with 1/2 teaspoon salt. Add butter, and cut with pastry blender or pulse until butter is size of peas. Add up to 1/4 cup ice water, just until mixture holds together (if using food processor, transfer mixture to bowl first). Turn onto lightly floured surface and pat into shape of small rectangle. Chunks of butter will show. Roll out dough, making rectangle about 5 by 7 inches, 1/2 inch thick. Fold narrow ends toward center so they meet. Fold in half again to make 4 layers. Give dough quarter turn, and repeat rolling and folding. Repeat another time. Roll dough again, but this time fold it in thirds like a business letter. Wrap in plastic, and refrigerate 45 minutes to 1 hour.
• Meanwhile, heat oil in large skillet over medium-low heat. Add onions, garlic, thyme and rosemary, and cook, stirring occasionally, until onions are soft and golden, 50 to 60 minutes. Add tomatoes, increase heat and cook until almost dry, 10 to 15 minutes. Add anchovies and olives, season and set aside.
• Preheat oven to 400 degrees. On floured surface, roll dough to make rectangle 9 by 13 inches, 1/4 inch thick. Crimp edges, and transfer to baking sheet. Cover dough with onion mixture to within 1/2 inch of edge. Bake until crust is golden, 30 to 40 minutes. Cut in portions or small squares, and serve.

VIDALIA ONION TART WITH BACON, LOCAL HONEY, AND FRESH THYME

Steps:

• To prepare the pastry, pulse together the flour, butter, and salt in the bowl of a food processor fitted with a plastic blade until the butter is about the size of small peas-about ten pulses. Gradually, drizzle in the ice water while pulsing. The amount needed will depend on the moisture content of the flour. Add just enough water for the dough to form a loose ball. Turn the pastry out onto a lightly floured surface and quickly form the dough into a 1-inch-thick disk. Wrap with plastic wrap and refrigerate for 30 minutes (or up to three days) to rest. Preheat oven to 375 degrees about 20 minutes before you're planning to bake the tart.
• Meanwhile, prepare the filling. Heat a large sauté pan over medium-high heat. Add the bacon in a single layer and cook, turning as needed, until the bacon is crispy and the fat has been rendered. Remove the bacon to drain on paper towels to cool, chopping coarsely once cool enough to handle. Reserve 2 tablespoons of the bacon fat (discarding the rest or using for another purpose) in the pan and reduce the heat to medium. Add the onions, salt, pepper, and thyme. Cook over medium heat until the onions have softened, stirring frequently, about 15 minutes. Do not let the onions brown!
• Add the wine and increase the heat to medium-high. Cook until the wine has cooked down to a glaze, about 3 minutes. Reduce the heat to medium-low and add the honey and reserved chopped bacon. Stir and cook 5 minutes more. Remove the onion mixture from the heat and spoon into a shallow pan; refrigerate to cool. When cooled, drain off any excess pan juices and stir in the egg and cream. Adjust seasonings as needed.
• To assemble, roll the reserved dough to 1/4 inch thickness. Line the pan(s) with the pastry and form even edges. Refrigerate another 10 minutes, then line the pastry with parchment paper and fill with pie weights. Bake 20 to 25 minutes, or until lightly browned. Remove the paper and weights and bake another 15 to 20 minutes to brown the bottom. Allow to cool slightly before filling. Reduce the oven temperature to 350 degrees. Fill the pastry crust with the onion mixture and bake until golden brown and the filling is set, about 35 minutes.
