Directions
Slab pie is a fun way to make pie for twenty-five people without making multiple pies. It’s not a true pie ratio. It’s slimmer in profile and contains less filling per inch than a round pie, but it’s still pie. It’s a huge pie that saves you lots of time and makes you a superhero for producing dessert for a big crowd. You will win the office potluck award with your slab pie. You will be a potluck dessert legend.
Steps

1
Done

Position a rack in the center of your oven and preheat the oven to 400°F. Place a parchment-lined baking sheet on the lower rack to catch any juices that fall when baking the slab pie. Have a 13 x 18-inch rimmed baking sheet nearby. |

Make the CrustRemove the dough from the fridge and remove the plastic from the disc. If your dough has been chilled overnight, it will need to sit at room temperature a bit before rolling—this will take 10 to 15 minutes. |

Lightly flour your work surface and roll the pie dough into a 14 x 19-inch rectangle. Transfer the crust to the rimmed baking sheet and press into the bottom edges and up the sides. Fold the extra dough under itself and crimp or pinch decoratively. Refrigerate the crust while you prepare the topping and filling. |

Place the pie on the center rack of the oven and reduce the temperature to 375°F. Bake until the crust is golden brown and the juices are bubbling, about 1 hour. Let cool completely on a wire rack before serving. Leftovers can be stored in a sealed container at room temperature for 1 day or up to 1 week in the fridge. |
