Best 9 French Onion Tartlets Recipes

FRENCH ONION TART

Steps:

• Preheat the oven to 400 degrees F. Line a baking sheet with parchment paper.
• On a work surface, roll the puff pastry into a roughly 10 by 16-inch rectangle. With a sharp knife, trim uneven edges to make a perfect rectangle. Evenly cut off the outer 1 inch of each side of the rectangle in strips; put the puff sheet on the baking sheet. Dip your finger in water and run around the top edges of the rectangle and replace the removed strips of pastry along the edges of the sheet, pressing lightly to adhere. With a fork, pierce the interior of the tart shell to prevent rising; do not pierce the adhered edges. Bake until the outer edges have puffed and are golden in color; about 15 minutes. Set aside.
• Heat 2 tablespoons olive oil in a large skillet over medium-low heat. Add onions and thyme sprigs and season well with salt and pepper, to taste. Cook, stirring occasionally, until the onions begin to brown. Add the stock, a tablespoon at a time, as the pan gets dry, scraping and stirring the brown bits that are stuck to the bottom oft the pan. When the onions are caramelized to a dark golden color, remove from the heat and discard the leafless thyme sprigs (the leaves fall off while cooking).
• When ready to serve, preheat the oven to 350 degrees F. Evenly spread the caramelized onions on the cooked pastry shell and heat in the oven until warmed through, 5 to 7 minutes. Remove from oven, to a cutting board and cut into wedges. Arrange on a serving platter and garnish each wedge with a sprig of fresh thyme. Serve immediately and enjoy!

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.
