Roasted Onion Tarts Recipes

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.

ROASTED ONION TARTS

Steps:

• Preheat oven to 425° F. and lightly grease 2 large baking sheets.
• Slice enough of red and yellow onions to measure 5 cups each and in a large skillet cook in 3 tablespoons oil with salt and pepper to taste, covered, over moderate heat, stirring occasionally, until golden and tender, about 15 minutes. Stir in cream and cool.
• Trim remaining onions and cut lengthwise into sixths, keeping wedges intact, and arrange, narrow sides up, 1/2 inch apart on baking sheets. Sprinkle onion wedges with salt and pepper to taste and roast in middle and lower thirds of oven 20 minutes, or until tender. Cool onion wedges.
• On a lightly floured surface with a lightly floured rolling pin roll out 1 pastry sheet into a 13-inch square. Using an inverted 6-inch plate as a guide, cut out four 6-inch rounds, discarding scraps. Cut out 12 more rounds from remaining 3 pastry sheets in same manner to make a total of 16 rounds.
• Fold in edge of each pastry round to form a 1/4-inch-wide border. (If pastry becomes too soft to work with, chill until firm.) Transfer rounds to 2 large baking sheets and chill until firm, about 10 minutes. Top each round evenly with a scant 1/4 cup sliced onion mixture. Arrange roasted onions on their sides decoratively (alternating yellow and red) on top of tarts and season with salt and pepper. Bake tarts in middle and lower thirds of oven, switching positions of pans halfway through baking, 20 to 25 minutes, or until bottoms are golden brown and roasted onions are very tender. Transfer tarts to racks to cool. Tarts may be made 1 day ahead and chilled, covered loosely with plastic wrap. Bring tarts to room temperature before serving or heat in a preheated 350° F. oven until heated through.
• Brush tarts with additional oil and serve whole or halved.

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.

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.

• Preheat oven to 350F and put a baking sheet in the oven.

• Remove from the oven and brush with some beaten egg (from the filling) return to the oven for 5 minutes.
• Then spread the onions all over the base of the flan, mix the eggs with the milk, salt and pepper, and pour as much as possible over the onions, you might have some left it depends on how much the onions have reduced.
