Mushroom Onion Tart Recipes

5 INGREDIENT ONION TART WITH MUSHROOMS RECIPE

Steps:

• Preheat the oven to 400˚F. Thaw the puff pastry according to the package directions, and carefully unfold it. The dough will look a little rough on the folds, so lightly roll it out using a rolling pin to even out the surface.
• Use a sharp knife to slice 1 inch off of each side. Baste the edges of the square pastry with water using either a basting brush or your finger.
• Then place all the cut edges onto the pastry square, forming a frame. This raised area will be the crust for the tart.
• Line a baking sheet with parchment paper or foil, and place the puff pastry on it. Using a fork, prick the bottom of the tart numerous times. This will allow steam to escape without billowing the tart bottom up. Bake until lightly browned, about 25 - 30 minutes. If the tart bottom billows, prick with a sharp knife and gently press down. There's no need to completely flatten it, since the filling will weight it down.
• When cooled, spread the bottom of the tart with the Dijon mustard. You don't need much - it just adds depth of savory-ness.
• Thinly slice the onions using a sharp chef's knife. Add 2 tablespoons butter to a skillet and melt over medium-high heat. Pile in the sliced onions with 1/2 teaspoon salt, using tongs to toss and coat with the butter. The onions will begin to relax in 5 - 10 minutes. At this point, reduce the heat to medium. Sauté for 45 minutes, or browned.
• Finely chop the mushrooms and sauté In a separate pan with 1 tablespoon of butter, 5 twigs of fresh thyme, and the remaining 1/4 teaspoon of salt over medium-low heat. Occasionally move around the pan, and sauté until the pan is dry. Mushroom contain a lot of liquid, and this can take 20 minutes or more. The mushrooms will be browned. Remove the thyme twigs when finished.
• Add the mushrooms to the onions and stir to combine.
• Lower the oven temperature to 350˚F. Fill the puff pastry with the onion filling. Add the tomatoes if using. Bake for 10 minutes. Remove the tart from the oven and lightly sprinkle fresh thyme on top before serving.
• Serve warm. Slice in half or quarters. For an appetizer, slice into small squares.

MUSHROOM AND CARAMELIZED ONION TART

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.

• 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.

ONION, BACON AND MUSHROOM TART

Steps:

• Preheat oven to 200C/fan 180C
• Make the pastry by rubbing the butter into the flour to resemble breadcrumbs. Stir in about 8 tbsp of fridge cold water and bring together to a ball using your hands.
• Chill in the fridge for 10 minutes.
• While the pastry is chilling finely slice the onions and place in a pan with some butter or oil and gently soften and allow to caramalise, will take about 20 minutes. Set aside to cool.
• Take the pastry from the fridge, roll out on a lightly floured surface and line a large greased tart case. Prick with a fork and lay over a sheet of greaseproof paper or foil and cover with baking beans or rice and cook in the centre of the oven for 20 minutes.
• While this is cooking cut the bacon into smallish pieces and fry in a pan with a little oil until cooked and crisp, then add to the onions. In the same pan add the sliced mushrooms and fry slightly to crisp up then cook down until fully cooked with a little butter, worcetser sauce, a thyme sprig and seasoning. Once cooked add to the bacon and onions and sprinkle in half the chopped parsley.
• In a jug mix together the eggs, creme fraiche, a little seasoning and the rest of the parsley.
• After the 20 minutes is up, remove the pastry case form the oven and take out the greaseproof paper and baking beans or rice. Put back into the oven for a furthur 15 minutes or until the pastry browns slightly and is cooked.
• Once browned remove from the oven and fill the pastry case with the onion, bacon and mushroom mixture and pour over the egg mixture. Place back in the centre of the oven for around 30 minutes or until the filling is nearly set as it will finish cooking as it cools slightly. Once out of the oven let it stand to set for 5 minutes and serve warm in slices with salad and home made chips or roasted potatoes.

MUSHROOM-ONION TART

• Bake pie crust for 10 min. at 400 deg. Cook mushrooms in shortening and put in bottom of baked crust. Save shortening. Mix remaining ingredients and add saved shortening. Pour over mushrooms in pie shell. Bake 350 deg. for 20 min. or until golden brown.

WILD MUSHROOM TART

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.

MUSHROOM TART

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.
