Best 7 Portobello Onion Tart Recipes

PORTOBELLO & ONION TART

Steps:

• Preheat oven to 400°. Unfold puff pastry onto a parchment paper-lined baking sheet. Using a sharp knife, score a 1/2" border along edges of pastry. Within border, prick pastry with a fork. Bake 8-10 minutes or until golden brown. Remove from oven. If center has puffed, flatten gently with a spatula. , Meanwhile, in a large skillet, heat 1 tablespoon oil over medium-high heat. Add mushrooms; cook and stir 4-5 minutes or until lightly browned. Remove from pan. To same pan, add remaining oil and the onion; cook and stir 2-3 minutes or until lightly browned. Return mushrooms to pan; stir in salt. , In a small bowl, whisk eggs until blended; stir in cheese. Pour into crust. Top evenly with mushroom mixture. Bake 13-15 minutes or just until cheese mixture is set. If desired, sprinkle with rosemary.

SORREL AND ONION TART

Steps:

• In a heavy, deep saucepan, melt butter over medium-low heat. Add onions. Cook, stirring frequently, until onions are soft and translucent, about 15 minutes.
• Remove and discard the tough center ribs from the sorrel leaves. Bring a large stockpot of water to a boil, and add 2 teaspoons salt. Add sorrel, and cook just until the leaves wilt, 1 to 2 minutes. Drain sorrel in a colander, let cool, and squeeze out any excess liquid.
• Add sorrel, the remaining teaspoon salt, and the pepper to the onions; cook over low heat until mixture breaks down and is almost soupy, about 20 minutes. Remove from heat, and let cool.
• Preheat oven to 400 degrees. Line two baking sheets with parchment. On a lightly floured surface, roll one sheet of puff pastry into a 7-by-11-inch rectangle, about 1/8 inch thick. Transfer the dough to one of the parchment-lined baking sheets, and chill in refrigerator 30 minutes. Repeat process with the second sheet of puff pastry. Remove both sheets of puff pastry from the refrigerator. Using a sharp knife, score a 1/2-inch border around perimeter of each sheet, creating a picture-frame look. Using a fork, prick the entire surface within the scored edges on each sheet. Make an egg glaze: In a small bowl, combine 1 egg yolk and 2 tablespoons heavy cream; carefully brush egg glaze onto the borders.
• Transfer both sheets of dough to oven, and bake until pastry has puffed up and is golden brown, about 15 minutes. Remove pastry from oven, and transfer to a wire rack to cool.
• Add the remaining egg yolk and remaining 2 tablespoons cream to the sorrel mixture, and stir to combine. Divide the filling in two, and spread one half over each puff pastry. Return the tarts to the oven, and bake until the filling is hot throughout, about 20 minutes. Remove the tarts from the oven, and transfer to a wire rack to cool, about 10 minutes. Cut tarts into 2-inch squares, and serve warm.

MEATLESS MUSHROOM TART

Steps:

• Preheat oven to 400 degrees F (200 degrees C). Lightly grease a baking sheet.
• Line a 10-inch pie dish with 1 sheet of puff pastry. Trim the edge so 1 inch hangs over the rim of the dish.
• Bake in preheated oven just long enough to set the pastry, 5 to 10 minutes.
• Cut the second sheet of puff pastry into 1 inch wide strips. Place the strips on the prepared baking sheet. Refrigerate the strips and the baked pie shell for at least 30 minutes, or up to 24 hours.
• Meanwhile, melt the butter in a skillet over medium-high heat. Stir in the onions, and cook until soft and transparent, about 6 minutes. Stir in the mushrooms and thyme, and cook until the mushrooms soften and release their juices, about 6 minutes. Mix the cream cheese into the mushroom mixture, stirring until melted. Season to taste with salt and pepper.
• Spoon the mushroom mixture into the pie shell. Arrange the pastry strips in a lattice pattern across the filling. Fold and crimp the ends of the strips together with the pie shell edge trimming any necessary pastry to make an even edge.
• Whisk the egg yolk and milk together in a small bowl, and use to brush the top of the pie.
• Bake in preheated oven until the crust is golden brown and the filling is heated through, up to 45 minutes. Check for doneness after 30 minutes. Cool another 30 minutes before serving.

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.

PROVENCAL ONION TART

Steps:

• Preheat oven to 425 degrees. Melt butter with oil in a medium skillet over medium-high heat. Add onions and thyme, and cook, stirring occasionally, until onions are golden and soft, about 10 minutes.
• On a lightly floured surface, roll out pastry to an 8 1/2-by-15-inch rectangle, trimming edges to make them straight. Place on a parchment-lined baking sheet, transfer to oven, and immediately reduce oven temperature to 400 degrees. Bake until pastry just begins to puff, about 12 minutes.
• Arrange onions in a single layer over pastry, leaving a 1-inch border all around. Top with olives and anchovies (if desired). Bake 15 minutes. Reduce oven temperature to 375 degrees, and continue baking until tart is puffed and golden around the edges, about 15 minutes more (tent with foil if crust browns too quickly). Let cool slightly before cutting into small squares and serving.

ROASTED PORTOBELLO WITH CARAMELIZED ONION RAVIOLI

Steps:

• For Filling #1: Preheat oven to 400 degrees. Pour olive oil into a skillet and saute onions and garlic for approximately 2 minutes. Add mushrooms, chicken stock, salt and pepper. Put the mixture in the oven and bake for 30 minutes, stirring every 10 minutes. Once cooked, place the mushroom mixture in a food processor. Add parsley and additional salt and pepper to taste. Then, while machine is running, add enough olive oil to make a smooth filling. Process until pasty, or chunky depending on preference.
• For Filling #2: Cube 2 small eggplants and then toss with oil and enough bread crumbs to coat. Salt and pepper to taste. Place in a roasting pan and bake in a preheated 400 degree for 45 minutes. After cooking put the eggplant in a mixing bowl and add mozzarella, Romano, tomato paste and whole egg. Mix until all are incorporated into a thick, and somewhat smooth mixture for the filling. Add olive oil to make a paste. Then add additional salt and pepper to taste. Put filling into already made ravioli dough.
• For Ravioli Dough: Mix eggs and flour, add warm water to soften dough during kneading. Hand kneading is preferred. Knead 5 minutes for elastic consistency. Spread dough and punch out 2.1/2 to3-inch circles, the size of an open soup can. Spoon completed filling into center, leave 1/2-inch perimeter around filling. Place mixture on 1/2 of circle, fold and pinch around circumference. Make sure dough is moist. Wet finger to seal. NO air pockets, must seal tight. Boil pot of water and 1/2 tablespoon salt. Place ravioli in water. Allow to boil 1 minute after they float to the top. Remove from water and place on a plate.
• For the Spinach Cream Pesto Sauce: Combine ingredients in a food processor and process. Transfer mixture to a saute pan. Heat over low heat and then pour over ravioli's.

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.
