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.

ONION TART

Steps:

• Preheat oven to 350 degrees F. Sift flour, sugar and salt into a bowl. Rub in the diced butter until the mixture resembles bread crumbs. Combine the mixture with the egg and cream.
• Melt the butter in a saute pan, add onions, salt and pepper. Cook onions until soft and golden in color.
• Grease a deep 12-inch flan tin, and line with grease-proof paper. Roll out pastry so that it is larger than the flan tin and bake blind for 10 minutes. Trim pastry edges and leave to cool.
• Strain the juice from the onion mixture and fill the pastry case. Whisk the eggs and cream together and pour over the onions. Grate the cheese over the top and place in oven for a further 30 minutes or until the egg mixture is set.

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.
