Pulse a few times until the butter is the size of a pea.
Transfer the dough onto a clean work surface and begin shaping the dough with your hands. It may seem dry at first but eventually, the warmth of your hands will slightly melt the butter making the dough more pliable.
Form the dough into a disk and wrap it in plastic wrap. Place it in the fridge for about one hour until firm.
Lightly flour your work surface and use a rolling pin to roll the chilled dough out to a 14-inch circle.
Use a rolling pin to gently transfer the dough onto a parchment-lined baking sheet.
Use a large spoon or your clean hands to mix everything together gently.
Add the pear mixture into the center of the dough and spread it out while leaving a 2-inch border. Then fold in the crust border, brush with egg wash, and sprinkle a little bit of coarse sugar on top.
Bake at 400 °F for about 25-30 minutes. Enjoy warm with vanilla ice cream on top.
