Portobello Onion Tart Recipes

PORTOBELLO TART WITH SPRING GREENS AND LIME BALSAMIC VINAIGRETTE

Steps:

• For the vinaigrette:
• Squeeze the lime juice (from the now cooled lime) through the feed opening of a running blender. With the blender still running, add the vinegar, corn syrup, shallot and rosemary, 1 at a time, and pour the oil in a slow steady stream into the vinegar mixture very slowly to emulsify. Remove to a container and season with salt and pepper, to taste.
• For the spring greens:
• Tear the greens into bite-sized pieces, and remove the stems if using arugula. (Make sure greens are no longer wet from being rinsed.) Toss greens with Parmesan, season with salt and pepper, to taste, and set aside.
• For the filling:
• Heat the clarified butter over medium heat in a large saute pan. Add the onion and cook for about 15 minutes until translucent and beginning to caramelize, then add the portobellos and white mushrooms to the onions. Cook for another 10 minutes then reduce heat to low and add the tomatoes, chives, salt, and pepper, and allow flavors to integrate.
• For the vol-au-vent (tart pastry):
• Preheat oven to 375 degrees F.
• Roll out puff pastry dough, and using a 4-inch circle cutter (aka biscuit cutter), cut out 8 dough rounds. Place 4 of the dough rounds on a lightly greased baking sheet. Using a 3-inch circle or biscuit cutter, cut a concentric circle in the middle of the remaining 4-inch dough rounds to create a 1/2-inch wide circle of dough. These 1/2-inch wide circles of dough are to be used without the 3-inch pieces from the center. Place 1 of these 1/2-inch wide circles of dough on top of each of the rounds already on the baking sheet, matching up the edges. Brush egg wash over the surface of each of the paired dough circles and rounds. Then use a fork to prick through the dough around the perimeter (that is, through each dough circle and into the accompanying round beneath it). Place in the oven and bake until golden brown, about 6 to 8 minutes. The center of each will rise. Remove pastry shells from oven and allow to cool slightly.
• Using the tip of a butter knife, break through the risen center part of each pastry shell to make a crater. Spoon some of the mushroom mixture into each of these craters. Place some greens on top of each tart and drizzle with lime balsamic vinaigrette.

GRILLED PORTOBELLO BURGER WITH ONION JAM

Steps:

• Put the yogurt in a paper towel-lined strainer set over a bowl, set aside to drain and thickened, about 60 minutes. Discard the watery liquid. Whisk the horseradish into the thickened yogurt.
• Meanwhile, heat 2 tablespoons of the olive oil in a medium skillet, over medium heat. Add the onions, 1 thyme sprig, and season with salt and pepper, to taste. Cook, covered, until the onions have wilted, about 10 to 15 minutes, (give them a stir every now and then with a wooden spoon to prevent them from sticking). Add the red wine, and simmer over high heat until most of the wine gets absorbed into the onions. Add the honey and red wine vinegar and simmer gently until the onions get jam-like, about, about 15 minutes.
• Preheat a stove top grill pan over medium-high heat. Whisk the remaining 2 tablespoons oil, garlic, and balsamic vinegar in a bowl. Strip and add the leaves from the remaining sprig of thyme. Coat the mushroom caps all over with the flavored olive oil. Grill the mushrooms, turning as needed, until tender but not mushy about 3 to 4 minutes per side. Season with the salt and pepper.
• Sandwich the mushroom between the buns, top with some of the onion jam, some lettuce, and a dollop of the horseradish cream. Serve warm.

NORTHERN GREEK MUSHROOM AND ONION PIE

Steps:

• Heat 2 tablespoons of the olive oil in a large, heavy skillet over medium heat and add the onions. Cook, stirring, until they begin to wilt, and add salt to taste. Turn the heat to medium-low and cook the onions, stirring from time to time, until they are very soft and beginning to caramelize, about 15 minutes. Add the mushrooms, turn the heat up to medium-high, and cook until they begin to sweat and soften, about 5 minutes. Add the garlic and stir together until fragrant, about 1 minute, and stir in the paprika. Continue to cook until the mushrooms are tender and most of the liquid in the pan has evaporated, 5 to 10 minutes. Remove from the heat, taste and adjust salt, and stir in the mint, parsley, feta and freshly ground pepper to taste
• Heat the oven to 375 degrees. Brush a 10- or 12-inch tart pan or cake pan with olive oil and layer in 7 sheets of phyllo dough, placing them not quite evenly on top of one another so that the edges overlap the sides of the pan all the way around. Brush each sheet with olive oil (or a mixture of olive oil and melted butter) before adding the next sheet. Fill with the mushroom and onion mixture. Bring the overhanging edges of the phyllo in over the filling, brushing each sheet with more olive oil, then layer 5 more sheets of dough over the top, brushing each sheet with olive oil. Crimp the edges into the sides of the pan. Pierce the top of the pie in several places with a sharp knife. Bake for 40 to 50 minutes, until the top is golden brown. Serve warm or at room temperature. Recrisp the crust, if necessary, in a low oven for 10 to 20 minutes

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.

SORREL-ONION TART

Steps:

• Prepare the tart dough, partially prebake it, and set it aside.
• Melt 3 tablespoons of the butter in a wide pan, add the onion and the salt. Cover the pan, and stew slowly until the onion is completely soft, about 10 minutes. Check it occasionally and give it a stir.
• While the onion is cooking, cut off the stems of the sorrel leaves and roughly slice the leaves. Melt the remaining tablespoon of butter in a pan, and add the sorrel by large handfuls. Although the amount of leaves will seem voluminous, they will quickly cook down to almost nothing. Cook over a low heat until they have wilted and turned a grayish-green color, 3 to 4 minutes.
• Whisk the eggs with the cream; then stir in the onion, sorrel, and half of the cheese. Taste for salt, and season with freshly ground black pepper.
• Preheat the oven to 375°F. Distribute the remaining cheese over the crust; then pour the filling on top. Bake in the center of the oven until the custard is set and well colored, about 35 to 40 minutes. Serve the tart while it is hot. For wine, consider serving a chardonnay or French white Burgundy.
• This tart is based on a recipe from Richard Olney's Simple French Food.
