Ingredients
  

  • 1 1/3 cups Flour
  • 1/4 teaspoon Salt
  • 8 tablespoons Butter chilled
  • 1/4 cup ice water
  • 2 tablespoons Butter
  • 3 small Shallots peeled and diced
  • 2 ounces Pancetta diced
  • 1 pound Cremini or white button mushrooms cut into 1/4-inch slices
  • 1 tablespoon fresh thyme leaves chopped
  • 1 cup Crème fraiche
  • 1 Egg
  • 1/2 cup Parmigiano-Reggiano grated
  • Salt and freshly ground pepper
  • White Truffle Salt optional (but it's why I made the tart!)

Instructions
 

  • Preheat the oven to 425ºF.
  • Combine the flour and salt in a large, wide bowl.
  • Cut the butter into 32 pieces and add to the flour; toss to coat.
  • Working quickly with your fingertips, pinch the butter into the flour creating flakes of flour-covered butter. Do this until there are no chunks of butter left, only flakes.
  • Sprinkle the water on top then, using a fork, toss the mixture to evenly distribute the water.
  • Next, with your hands, pull the dough together and knead briefly to form a ball.
  • Refrigerate for 10 minutes before rolling.
  • Roll the dough into a 11-inch by 14-inch rectangle and put it in an 8-inch by 11-inch tart pan with a removable bottom.
  • Fold the excess dough down to make a thick rim for the tart, pressing it into the fluted sides.
  • Prick the bottom of the pastry all over with a fork, then put in the freezer for 20 minutes while you heat the oven to 425°F.
  • Line the tart shell with foil, and fill with dried beans or pie weights.
  • Bake until it’s lightly colored, about 20 minutes. Remove the tart and reduce the oven temperature to 400°F; remove the weights and foil.
  • Meanwhile heat a large skillet over medium heat. Add the butter and, when melted, add the shallots and pancetta. Cook until the shallots are soft and the pancetta has rendered its fat and is beginning to color.
  • Add the sliced mushrooms and the thyme leaves, and cook until the mushrooms are tender and browned. Set aside to cool.
  • In a small bowl, whisk together the crème fraîche, egg, and grated Parmigiano-Reggiano. Season with salt and freshly ground pepper.
  • Add this cream mixture to the cooled mushrooms and mix well.
  • Spread the mushroom mixture evenly into the tart shell and bake for 30-35 minutes, until crust is brown and filling is bubbling.
  • Sprinkle immediately with truffle salt and serve warm.
