Sure it can! While we've designed the pies in this course to work specifically as slab pies, you can adapt most recipes to work as a slab pie. Here's a general idea of how to do it.
For a double-crust slab pie, make 2 batches of your favorite double-crust pie dough. Divide each dough in half and shape according to our slab pie recipes.
If you're using store-bought dough, you'll need 2 (15-ounce) packages (2 crusts each).
Prepare 1½ batches of your favorite fruit pie filling recipe, shooting for 7 to 8 cups. Spread filling into dough-lined sheet.
Cut slits at 2-inch intervals. Bake at 350 degrees on lower-middle rack until crust is golden brown, 1 to 1¼ hours.
We love our Foolproof All-Butter Pie Crust, but if time is of the essence, you can use a good quality store-bought dough for a quicker slab pie. See our review of ready-made pie crusts here.
