Crostata with Apples, Walnuts, and Gorgonzola

Preparation

1. For the Apple Filling

   Step 1

   Melt the butter in a large nonstick skillet over medium heat. Add the apple slices, sugar, and cinnamon and cook, stirring frequently, for 5 minutes, until the apples are softened but not mushy. Set aside to cool for 10 minutes. Stir in the lemon juice and zest, walnuts, and Gorgonzola cheese.

   Step 2

   Place an oven rack in the lower third of the oven and preheat the oven to 400°F.

   Step 3

   Unwrap the chilled dough and place it on a sheet of parchment paper. Roll the dough into an 11-inch circle, about 1/4 inch thick. Lift the parchment paper and transfer it and the dough to the baking sheet.

   Step 4

   Spread the cooled apple filling in the center of the dough circle, leaving a 2-inch border. Fold the dough border up over the filling to form an 8-inch round, pleating the edge of the pastry. Brush the crust with the beaten egg.

   Step 5

   Bake the crostata until the crust is golden, about 25 minutes. Cool on the baking sheet for 10 minutes before slicing.
