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.

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.
