Mushroom Onion Tart Recipes

MUSHROOM GALETTE RECIPE

Steps:

• Preheat the oven to 400°F. To a pan, add about a tablespoon of olive oil. Warm over medium heat and once hot, add in the onion slices. Cook until the onions begin to become golden along the edges and caramelize.
• Add the mushroom slices to the pan and cook for another few minutes until the mushrooms are tender. Turn off the heat and temporarily set the pan aside.
• Unroll the pie crust onto a baking sheet fitted with parchment paper or a silicone baking mat. Brush the egg white over most of the pie crust, leaving about a 1 1/2 inch perimeter bare. Let the crust rest for a minute for the egg white to slightly dry.
• Spread the ricotta cheese all over the area covered with the egg white. Use a zester to finely grate a little bit of parmesan cheese as a slight garnish over all the ricotta cheese. Add a small pinch of salt and freshly ground pepper, as well as the pinch of nutmeg, over the cheese.
• Distribute the mushroom-onion mixture all over the ricotta cheese, then top that with the shredded gruyere. Add the thyme leaves all over the top.
• Fold the edges of the pie crust over the mushroom filling, all along the edges. Brush the egg yolk over the pastry, then top the pastry with some of the finely grated parmesan.
• Bake the galette for 20-30 minutes. If you're using store-bought crust, it will typically look golden and be ready in the 20-25 minute mark, whereas homemade pastry can take up to 30 minutes.
• Let the galette rest for 10 minutes on the baking sheet, then transfer to your serving plate.

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.

CARAMELIZED ONION, MUSHROOM AND GOAT CHEESE TART

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.

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.

ONION, WALNUT & MUSHROOM TARTE TATIN

Steps:

• Heat oven to 200C/180C fan/gas 6. Peel the onions and cut each into 6 wedges through the root. Heat the oil in a large pan, add onions, then gently fry for 20 mins until softened and lightly coloured.
• Add the mushrooms, sugar, salt and pepper and give it a good stir. Gently cook, stirring now and then for a further 5 mins. Stir in the walnuts. Line the base of a 20-23cm sandwich cake tin (not loose-based) with baking parchment. Spoon over the onion mixture and press it down lightly. Crumble the cheese over.
• Roll out the pastry and trim to a round, about 5cm larger than the tin. Put the pastry over the filling and tuck in the ends. Bake for 35-40 mins until the pastry is crisp and golden. Cool for 5 mins in the tin, then turn out onto a flat plate and cut into wedges. Serve with a green salad.

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.

CARAMELISED MUSHROOM TARTLETS

Steps:

• Heat the oil in a generous frying pan, add the onion and fry over moderate heat for about 7 mins until soft and golden. Stir in the sugar and seasoning, turn up the heat and add the mushrooms. Sizzle for 5 mins until you have driven off any moisture and the mushrooms are golden. Stir in the garlic for a few further mins, until fragrant, then turn off the heat and stir in most of the thyme (save some for sprinkling). The mushroom mix can be chilled at this point.
• To make the tartlet bases, cut 7-8cm circles out of the bread using a cookie cutter or glass. Butter one side and stick buttered-side down into a 12-hole tartlet tin. Freeze any leftovers to make breadcrumbs.
• When ready to bake, heat oven to 220C/200 fan/gas 7. Divide the mushroom mixture between the tartlets and top with a sprinkle of cheese. Don't be too tidy about this - any cheese on the tin will form a lacy edge to the tartlets. Bake for 10-15 mins until golden and bubbling. Sprinkle over the reserved herbs and serve.
