    Ingredients for Apple Slab Pie

      for the pie

      • 8 Granny Smith apples peeled, cored, and sliced thin
      • 8 Golden Delicious apples peeled, cored, and sliced thin
      • 1 1/2 cups sugar
      • 1/2 teaspoon salt
      • 1 1/2 cups animal crackers
      • 2 boxes refrigerated ready to roll pie crusts I am using Pillsbury: use 1 box of 2 crusts for the bottom and 1 box of 2 crusts for the top
      • 4 tablespoons unsalted butter
      • 6 tablespoons tapioca or cornstarch
      • 2 teaspoons cinnamon
      • 3 tablespoons lemon juice

      for the glaze

      • 3/4 cup apple juice reserved from the apples used in this recipe
      • 2 tablespoons lemon juice
      • 1 tablespoon unsalted butter
      • 1 1/4 cups confectioner's sugar


      For a full recipe, an 18" x 13" nonstick baking sheet is preferred; if using a conventional sheet pan, coat it lightly with cooking spray. For a half recipe, use a 9 1/2" x 13" pan.

        The Method

          for the pie

          • Toss apples, 1 cup sugar, and salt in colander set over large bowl. Let sit, tossing occasionally, until apples release their juices, about 30 minutes. Press gently on apples to extract liquid and reserve 3/4 cup juice (any excess may be discarded).
          • Adjust oven rack to lower-middle position and heat oven to 350 degrees F. Pulse animal crackers and remaining sugar in food processor until finely ground. Dust work surface with cracker mixture. Brush half of one pastry disc with water, overlap with second pastry disc, and dust top with more cracker mixture. Roll out dough to 19 by 14 inches and transfer to rimmed baking sheet. Brush dough with butter and refrigerate; roll out top crust in the same way.
          • Toss drained apples with tapioca, cinnamon, and lemon juice and arrange evenly over bottom crust, pressing lightly to flatten. Brush edges of bottom crust with water, and arrange top crust on pie. Press crusts together and use a paring knife to trim any excess dough, leaving a 1/2" rim of pastry; fold pastry under itself and tuck into rim of baking sheet. Use fork to crimp and seal outside edge of pie, then pierce top of pie at 2-inch intervals with fork. Bake until pie is golden brown and juices are bubbling, about 1 hour. Transfer to wire rack and let cool 1 hour.

          for the glaze

          • For the glaze: While pie is cooling, simmer 3/4 cup apple juice (which you reserved in step 1) in saucepan over medium heat until syrupy and reduced to 1/4 cup, about 6 minutes. Stir in lemon juice and butter and let cool to room temperature. Whisk in confectioners' sugar and brush glaze evenly over warm pie. Let pie cool completely, at least 1 hour longer. Cut into thirds lengthwise, and into sixths widthwise, making 18 pieces each about 4"x3".


          Make Ahead: The pie can be made up to 24 hours in advance and refrigerated. Bring to room temperature before serving.
