Preheat oven to 350 degrees. In the bowl of a food processor, combine flour, sugar, butter, and salt; process until mixture resembles coarse meal, 15 to 20 seconds. Add eggs one at a time, and process until dough just comes together.
Press dough into a 10-inch round tart pan with a removable bottom. Cover with plastic wrap, and refrigerate for at least 1 hour.
