Mushroom Onion Tart Recipes

Steps:

• Preheat oven to 400 degrees F.
• Using a mandolin or super-sharp knife, cut onion into paper thin slices. Clean and slice the mushrooms.
• Heat 1 tablespoon oil in a skillet over medium heat; add onion and saute until caramelized. Transfer to a bowl and set aside. Heat remaining teaspoon of oil in skillet over medium-high heat. Add mushrooms and saute until they release all their liquid and most of it boils away, should take about 5 minutes. Combine caramelized onions with mushrooms and saute together briefly; season with salt and pepper. Remove the pan from heat.
• Unfold puff pastry onto a floured surface; cut in half lengthwise to form 2 long rectangles. Gently roll out each rectangle to approximately 5 by 14 inches and place on cookie sheet. Trim edges by 1/4-inch strips all around; set strips aside. Break 1 egg into a small bowl; beat slightly. Brush edges of pastry with some of the egg. Use trimmed strips to make a raised border on each. Brush entire surface with remaining beaten egg. Prick the interior of pastry all over with a fork. Bake until pale gold, about 10 minutes. If pastry has puffed up inside edge, press it down gently. Set aside.
• Meanwhile, combine remaining eggs with 6 ounces goat cheese and blend until smooth. Spread the mixture onto pastry. Return to oven and bake just until set, about 4 minutes. Add the thyme to the mushroom mixture. Remove cookie sheet from oven and spread with thyme-mushroom mixture. Crumble remaining cheese on top. Just before serving, broil tarts on low heat for 2 to 3 minutes, until tarts are warm and cheese softens.

Steps:

• Put 175g Flora 100% Natural Ingredients, wholemeal flour, half the thyme and a pinch of salt in a food processor and pulse until it starts to clump together. Add 2-3 tbsp cold water and pulse again until it forms a ball. Wrap and chill for 20 mins.
• Meanwhile, heat the remaining 2 tbsp spread in a frying pan, and fry the mushrooms and onions for 10 mins until soft and lightly golden. Season well and remove from the heat.
• Heat the oven to 220C/fan 200C/gas 7. Add a large flat baking sheet to the oven to heat up. Whisk the soft cheese with half the chives, remaining thyme and all the garlic. Season well.
• Roll the pastry out in between two sheets of parchment to a rough rectangle shape, the thickness of a £1 coin, about 30x40cm. Remove the top layer of parchment and smooth over the soft cheese mixture, leaving a 5cm border. Spoon over the mushrooms, in an even layer over the soft cheese, then fold over the 4 sides of the border to overlap the filling slightly. Trim the sides before you fold over if you need to, but will look lovely when baked either way. Glaze the pastry with egg.
• Using the parchment to help you, slide the tart onto the hot tray with the paper. Bake for 35-40 mins until the pasty is cooked though, and crisp. Scatter with the remaining chives to serve, along with a green salad.

Steps:

• Make the tart dough: Put the 2 cups flour and salt in the chilled bowl of a stand mixer fitted with the paddle attachment. (If you don't have one, you can prepare the dough by hand.) With the mixer set on low speed, work half of the butter into the flour until the mixture resembles wet sand. Add remaining butter cubes and ice water, and mix just until the dough comes together. The dough will be very soft, studded with butter chunks and a bit sticky - this is correct.
• You should have 550 grams/20 ounces of dough. Divide into 2 (275-gram/10-ounce) balls. Dust each with a little flour and press into a disk about 1-inch thick. Cover with plastic wrap and chill for 30 minutes.
• Dust the work surface with flour. Press one disk into a rough square, then roll it into a 6-by-12-inch sheet. Fold the sheet in half, making a 6-inch square. Dust with flour lightly, as necessary, and roll the square into a 6-by-12-inch sheet again, then fold in half to make a 6-inch square. Finally, roll dough into a 6-by-18-inch sheet, place on a parchment-lined baking sheet and refrigerate, wrapped, for 30 minutes to keep dough from shrinking when baked, or freeze. (Roll out the rest of the dough at your leisure, then freeze for the future, or refrigerate and use within 2 days.)
• Make the filling: Set a wide skillet over medium-high heat and add olive oil. When oil is wavy, add onions. Season with salt and pepper, and cook, stirring, until softened and beginning to brown, about 10 minutes. Remove onions and set aside.
• In the same pan over medium-high heat, add mushrooms (and a little more oil if necessary). Season with salt and pepper, and cook, stirring, until softened and beginning to brown, 5 to 8 minutes. Add garlic, thyme and red-pepper flakes (if using), stir well and turn off heat. Combine mushrooms and onions, set aside and let cool to room temperature. (Filling can be made several hours in advance and left at room temperature, if desired.)
• Heat oven to 400 degrees. Using a small rubber spatula, spread crème fraîche over the pastry sheet, leaving a 1-inch border. Distribute onion-mushroom mixture evenly over the crème fraîche. Dust with Parmesan and fold pastry edges up, pinching at the corners to form a low rim. Bake until pastry is crisp and golden and top of mixture is lightly browned, about 30 to 35 minutes.
• Slide baked tart onto a cutting board and pull away the parchment. Let tart cool slightly before cutting. Sprinkle with parsley and cut tart crosswise into wide slices (or, if preferred, into wedges). Serve warm.

Steps:

• Preheat oven to 450 degrees F.
• Line a cookie sheet with a sheet of bakers parchment paper.
• Place a sheet of puffed pastry flat on parchment.
• In skillet over medium low heat add olive oil and butter.
• Saute onion for 15 minutes or until translucent. Stir frequently.
• Add mushrooms to skillet .
• Saute until tender about 15 minutes. Stir frequently.
• Add salt and pepper to mushroom onion mixture (to taste).
• Remove from heat and set aside.
• Mix egg and milk together with a whisk until well blended.
• Paint the puffed pastry with the honey mustard leaving a 1/2 inch border.
• Add the mushroom onion mixture on top of the mustard leaving about a 1/2 inch border.
• Sprinkle the cheese on top of the mushroom onion mixture.
• Paint the border of the puffed pastry dough with egg wash (Discard leftover egg wash).
• Place tart in oven and bake for 15-20 minutes until pastry has puffed up and browned.
• Enjoy!

Steps:

• Preheat oven to 400 degrees F.
• Place the flour, butter and salt in the bowl of a food processor. Pulse a few times to break up butter into little pieces... mixture should resemble coarse corn meal. With the machine running, add the water a tablespoon at a time until the dough holds together when squeezed. Gather the dough together and form into a rectangle. Wrap in plastic wrap and refrigerate for one half an hour.
• In the mean time, heat the butter and olive oil in a large sauté pan. Add the mushrooms, stir to coat, spread out in the pan and allow to cook, undisturbed for a couple of minutes. Stir once and redistribute, continue cooking in this same manor until mushrooms are golden brown. Remove from pan and set aside.
• Add onions to the same sauté pan; add additional olive oil is necessary. Sauté until caramelized well, season with thyme, salt and pepper.
• Divide pastry in half. Roll each piece of pastry into long strips, about 4 inches by 8 inches. Place on a parchment lined baking sheet and crimp the edge of the dough to create a rim. Cover the tart with parchment and fill with beans. Bake 15 minutes, remove the parchment and beans and bake another 5 minutes. Remove and allow to cool.
• Reduce the oven to 350 degrees F.
• Spread half of the cheese and half of the onions and half of the mushrooms on each tart. Bake for 15 minutes. Allow to cool 5 minutes.
• To serve, cut each tart in half length wise and then into 6 equal pieces. Arrange on a serving plate.
