Adapted from Giada DeLaurentiis
- 1 1/2 cups all-purpose flour
- 1/2 teaspoon salt, plus 1/2 teaspoon
- 3 tablespoons cold butter, cut into small pieces
- 1 1/2 tablespoons lemon juice
- 1/2 cup mascarpone cheese
- 3 tablespoons ice water
- 4 ounces diced pancetta
- 1 teaspoon chopped fresh thyme
- 2 cups sauteed cremini mushrooms
- 1 shallot
- 1/2 cup grated fontina cheese
- 1/4 teaspoon freshly ground black pepper
- 2 tablespoons freshly grated Parmesan
- 1 large egg, lightly beaten
In a food processor combine the flour, and 1/2 teaspoon salt. Pulse to combine. Add the butter and pulse until the butter is finely chopped and the mixture resembles a coarse meal. In a small bowl combine the lemon juice and mascarpone.
Add the mascarpone mixture to the food processor and pulse a few times. Add the ice water
and run the machine just until the mixture is moist and crumbly, but does not form a ball. Do not over mix. Turn the dough out onto a sheet of plastic wrap. Press into a disk, cover, and refrigerate for 20 minutes.
Saute shallot in 1 teaspoon of olive oil. Once the shallots are tender, add the cremini mushrooms and saute until all liquid is evaporated - about 8 minutes. Remove from the skillet and place in a bowl to cool. Add the rosemary and stir.
Meanwhile, preheat the oven to 400 degrees F. Cook the pancetta in a small saute pan over medium heat until golden and crisp, about 4 minutes. Remove the pancetta using a slotted spoon and add to the bowl with the mushrooms.
Add the grated cheese and the remaining 1/2 teaspoon salt, and pepper.
Toss to combine and set aside.
Place the chilled dough on parchment paper. Roll the dough out into a 12-inch wide circle about 1/4-inch thick.
Spread the vegetables out in the center of the dough leaving a 2-inch border.
Sprinkle the vegetable mixture with Parmesan.
Fold the border up and over the vegetables forming a crust.
Using a pastry brush, brush some of the egg over the crust.
Transfer the parchment paper and crostata to a baking sheet. Bake until the crust is golden, about 25 minutes. Slice and serve.
