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.

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.
