Caramelised Red Onion Prosciutto Mushroom Tart Recipes

CARAMELISED RED ONION, PROSCIUTTO & MUSHROOM TART

Steps:

• Heat 3 tbsp oil in a frying pan, add the onion and gently cook until softened, about 10 mins. Add the thyme, vinegar, salt and pepper and cook for 5 mins more, stirring occasionally to stop them burning. Set aside to cool.
• Heat oven to 200C/180C fan/gas 6. Roll out the pastry, trim to a 28cm round, then put on a non-stick baking sheet (or one lined with baking paper). Fork the pastry all over.
• Spread the onion over the pastry to within 3cm of the edge. Tear the prosciutto into strips and arrange over the onion in a rippled effect. Arrange the mushrooms on top and brush them with the reserved oil. Slice or crumble the cheese and arrange over the tart. Season with salt and pepper.
• Push the side of the tart up with your fingers to form an edge. Bake for 30-35 mins until the pastry edges have puffed up and the mushrooms are tender. Cool for a few minutes, then scatter with rocket just before serving.

EASY TART WITH CARAMELIZED ONIONS, MUSHROOMS AND GRUYèRE

Steps:

• Heat a large saucepan over medium-high heat. When the pan is hot, add the olive oil and the butter together, followed by the sliced onions. Cook for about 10 minutes or until the onions wilt and start to brown. At that point add the next three ingredients (sugar, vinegar, salt and pepper). Reduce the heat and cook gently, uncovered for about 20 more minutes or until the onions are completely caramelized. Add a little water if the onions look like they are drying out. Taste and adjust the seasoning. Remove the onions to a separate bowl.
• Add the sliced mushrooms to the same pot and sauté (without oil) for a few minutes until they release their moisture. At that point, add a little olive oil and the thyme leaves and cook for a few minutes, stirring frequently. Once the mushrooms start lightly brown, add the sliced potatoes and the fennel seeds. Season everything with some salt and pepper and cook for a few more minutes, until the potatoes soften a little. Set the mixture aside to cool.
• Unfold the thawed sheet of puff pastry and place it on a work surface. Roll it out into a 10"x14" rectangle and remove it to a baking sheet lined with parchment paper. Prick with a fork every few inches to prevent the pastry from bubbling while it bakes. Using a very sharp knife, score the perimeter of the dough about ¼- to ½-inch from the edge.
• Spread the cooled onions evenly over the puff pastry. Top with the sautéed mushrooms and potatoes and sprinkle with the Gruyère cheese. (Refrigerate if not baking immediately).
• Preheat the oven to 375°F. Bake the puff pastry on the middle rack for 25-30 minutes or until the cheese is bubbling and crust is nice and golden. Allow the tart to cool for 10 minutes then cut it into 20 little rectangles. Serve warm or at room temperature.

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.

CARAMELIZED ONION AND ROASTED RED PEPPER TART

Steps:

• Dough:.
• Dissolve yeast and honey in warm water in a large bowl; let stand for 5 minutes.
• Lightly spoon flours into dry measuring cups, and level with a knife. Stir 1 cup bread flour and 1 tablespoon oil into yeast mixture. Cover and let rise in a warm place (85°F), free from drafts, 1 1/2 hours or until bubbly.
• Stir in 1/2 cup bread flour, whole wheat flour, and 1 teaspoon salt.
• Turn dough out onto a floured surface. Knead until smooth and elastic (about 10 minutes); dough will feel tacky. Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85°), free from drafts, for 1 hour or until doubled in size. (Press two fingers into the dough. If indentation remains, the dough has risen enough.) Punch dough down; cover and let rest 10 minutes.
• Topping:.
• Heat 1 tablespoon oil in a 12-inch nonstick skillet coated with cooking spray over medium-high heat. Add onion, and cook for 5 minutes, stirring frequently. Stir in 1 teaspoon salt, thyme sprigs, garlic, and bay leaves; cook for 15 minutes or until deep golden brown, stirring frequently.
• Remove from heat. Discard thyme sprigs and bay leaves.
• Preheat broiler.
• While onion is cooking, cut bell peppers in half lengthwise, discarding seeds and membranes. Place the pepper halves, skin sides up, on a foil-lined baking sheet; flatten with hand. Broil for 15 minutes or until blackened. Place in a zip-top plastic bag, and seal. Let stand for 15 minutes. Peel and coarsely chop.
• Preheat oven to 425°F.
• Roll the dough into a 12 x 8-inch rectangle. Place the dough on a baking sheet coated with cooking spray. Top with the onion mixture and the chopped bell pepper. Sprinkle with black pepper. Bake at 425°F for 25 minutes or until the crust is golden brown. Cool slightly. Sprinkle with chopped thyme. Cut into 8 squares, and cut each square in half diagonally. Garnish with thyme sprigs, if desired.

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.
