Red Onion Tart Recipes

CARAMELISED BALSAMIC AND RED ONION TARTS WITH GOATS' CHEESE

Steps:

• First make up the pastry by rubbing the butter lightly on to the flour, then adding the cheese, mustard and cayenne plus just enough cold water to make a smooth dough. Then place the dough in a polythene bag to rest in the refrigerator for 20 minutes. After that, roll it out as thinly as possible and use a 5 inch (13 cm) cutter, or a saucer or something similar, to stamp out 8 rounds. Line the greased tins with them, then bake in the oven, centre shelf, for 15-20 minutes or until the pastry is cooked through but not coloured. Then cool the pastry cases on a wire rack and store them in an airtight tin until they are needed. To make the filling, melt the butter in a heavy-based, medium-sized saucepan, stir in the onions, balsamic vinegar and chopped sage, season and let everything cook very gently without a lid, stirring often, for about 30 minutes until they have reduced down and taken on a lovely glazed appearance and all the excess liquid has evaporated away. You can also watch how to chop onions in our Cookery School Video on this page. Then let the mixture cool until you are ready to make the tarts. To bake them, brush a little beaten egg on to each pastry case, pop them back into the oven, same temperature as above, for 5 minutes - this helps to provide a seal for the pastry and helps it from becoming soggy. Now spoon the onion mixture into the cases. Top each one with a slice of goats' cheese and a sage leaf that has first been dipped into olive oil. Finally sprinkle with a little cayenne and bake for 20 minutes.

RED ONION, FETA & OLIVE TART

Steps:

• Heat oven to 220C/fan 200C/gas 7. Heat the oil in a frying pan, then gently fry the onions for about 10 mins until golden and soft. Add the sugar and balsamic vinegar, then cook for a further 5 mins until the juices are reduced and syrupy. Leave to cool.
• Unroll the puff pastry onto a baking tray. Score a line a finger-width in from the edge all the way around, then cover the middle with the onion mix. Scatter the feta and olives over. Season and drizzle the extra virgin olive oil over the topping.
• Bake for 15 mins or until the pastry is risen and golden and the base is crisp. Cut into wedges and serve with a green salad.

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.

COURGETTE & CARAMELISED RED ONION TART

Steps:

• Heat oven to 200C/180C fan/gas 6. On a lightly floured surface, roll the pastry out to slightly smaller than an A4 rectangle. Slide onto a baking tray, brush with the beaten egg and cook for 20 mins or until golden.
• Meanwhile, melt the butter in a frying pan over a medium heat. Once foaming, add the onions with a pinch of salt. Cook, stirring regularly, for 10 mins until soft. Pour in the balsamic and cook for a further 6-8 mins until sticky and caramelised.
• Spoon over the pastry, then top with the courgette ribbons and blobs of goat's cheese. Return to the oven for 15 mins until the cheese is bubbling. Serve with salad.

BEETROOT & RED ONION TARTE TATIN

Steps:

• Heat oven to 200C/180C fan/gas 6. In a bowl, toss the beetroot and onion in 2 tbsp of the oil, the vinegar and sugar. Add the star anise and season well. Heat the rest of the oil in a large, ovenproof non-stick frying pan, then nestle in the veg so that they cover the surface of the pan. Cover with foil and cook in the oven for 45 mins.
• On a well-floured surface, roll the pastry to a thickness of 0.5cm and cut out a circle the same size as your frying pan. Carefully take the pan out of the oven, remove the foil and wiggle the beets and onion around in the pan to make a compact layer. Put the pastry on top, tucking it in all around the edges, then return the pan to the oven and bake for 35 mins or until the pastry has puffed up and is a deep golden brown.
• Slide a palate knife around the edge of the tart, then put a plate on top of the pastry, serving side down. Flip the pan over to turn the tart out onto the plate - be careful not to burn yourself with the handle. Top with the orange zest and a sprinkle of sea salt, then serve with a peppery salad on the side.

CAULIFLOWER, RED ONION, AND CHESTNUT TART

Steps:

• Make the tart: Roll out pastry dough to a 6-by-16-inch rectangle on a lightly floured surface. Fit dough into a 4-by-13-inch fluted tart pan with a removable bottom. Trim edges flush with top. Prick bottom of tart all over with a fork. Refrigerate until firm, about 1 hour.
• Preheat oven to 375 degrees. Line crust with parchment, leaving an overhang on all sides. Fill with pie weights or dried beans. Bake until crust is set and edges are just starting to turn golden brown, about 25 minutes. Remove from oven, and remove pie weights and parchment. Bake until bottom of tart shell is pale gold, about 10 minutes more. Let cool completely on a wire rack. Reduce oven temperature to 350 degrees.
• Meanwhile, make the filling: Prepare an ice-water bath. Bring a pot of water to a boil. Cook onions for 2 minutes. Transfer to ice-water bath. Drain. Peel onions, and cut each in half. Meanwhile, steam cauliflower in a basket insert set over a pan of simmering water until almost tender, about 3 minutes. Season with salt. Let cool.
• Heat oil in a small skillet over medium heat. Cook onions, stirring, until browned, about 12 minutes.
• Make the bechamel: Melt butter in a medium saucepan over medium heat. Add flour, and cook, whisking, for 1 minute. Gradually whisk in milk, and cook, whisking, until mixture is thick and just starts to boil. Add 1/4 cup blue cheese, the thyme, and 1 teaspoon salt, and whisk until cheese melts. Stir in cauliflower, half the onions, and half the chestnuts.
• Spread cauliflower mixture onto tart shell. Scatter remaining onions and chestnuts over filling, and dot top with remaining 1/4 cup blue cheese. Bake tart on a baking sheet until filling is bubbling, about 45 minutes. Let cool on a wire rack for 15 minutes before serving.

CARAMELIZED ONION AND ROASTED RED PEPPER TART

Steps:

• Dough:.
• Dissolve yeast and honey in warm water in a large bowl; let stand for 5 minutes.
• Lightly spoon flours into dry measuring cups, and level with a knife. Stir 1 cup bread flour and 1 tablespoon oil into yeast mixture. Cover and let rise in a warm place (85°F), free from drafts, 1 1/2 hours or until bubbly.
• Stir in 1/2 cup bread flour, whole wheat flour, and 1 teaspoon salt.
• Turn dough out onto a floured surface. Knead until smooth and elastic (about 10 minutes); dough will feel tacky. Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85°), free from drafts, for 1 hour or until doubled in size. (Press two fingers into the dough. If indentation remains, the dough has risen enough.) Punch dough down; cover and let rest 10 minutes.
• Topping:.
• Heat 1 tablespoon oil in a 12-inch nonstick skillet coated with cooking spray over medium-high heat. Add onion, and cook for 5 minutes, stirring frequently. Stir in 1 teaspoon salt, thyme sprigs, garlic, and bay leaves; cook for 15 minutes or until deep golden brown, stirring frequently.
• Remove from heat. Discard thyme sprigs and bay leaves.
• Preheat broiler.
• While onion is cooking, cut bell peppers in half lengthwise, discarding seeds and membranes. Place the pepper halves, skin sides up, on a foil-lined baking sheet; flatten with hand. Broil for 15 minutes or until blackened. Place in a zip-top plastic bag, and seal. Let stand for 15 minutes. Peel and coarsely chop.
• Preheat oven to 425°F.
• Roll the dough into a 12 x 8-inch rectangle. Place the dough on a baking sheet coated with cooking spray. Top with the onion mixture and the chopped bell pepper. Sprinkle with black pepper. Bake at 425°F for 25 minutes or until the crust is golden brown. Cool slightly. Sprinkle with chopped thyme. Cut into 8 squares, and cut each square in half diagonally. Garnish with thyme sprigs, if desired.

CARAMELISED ONION TART

Steps:

• Heat oven to 190C/fan 170C/gas 5. Slide a baking sheet in to heat. Roll the pastry out enough to line a deep 20cm flan tin or a shallow 23cm one. Chill for 10 mins.
• Put a few balls of crumpled foil in the base of the pastry case and bake on the baking sheet for 10 mins. Remove the foil and bake for 5 mins more, until light golden.
• Meanwhile, cook the onions in the oil until starting to soften, then add thyme, pepper, and salt if you want to. Cook slowly for about 15 mins until the onions are soft and tinged brown.
• Beat the eggs, beat in the milk and half the cheese and some pepper. Spread the onions over the flan case and pour in the egg mix. Sprinkle the remaining cheese on top and bake the tart on the baking sheet for 30-40 mins until the filling is firm and golden, and the pastry crisp. Serve warm or cold.
