Method
 

Make the Crust Dough
  1. In a large mixing bowl, combine flour and salt. Whisk together to distribute salt evenly.
  2. Add butter-flavored shortening and cut into flour until mixture resembles pea-sized crumbs.
  3. Gradually add cold water one tablespoon at a time while mixing gently with a fork until dough starts to hold together.
  4. Divide dough into two portions, flatten into discs, and refrigerate for at least 20 minutes.
Prepare the Apple Filling
  1. Peel, core, and slice apples into thin slices.
  2. In a bowl, mix sugar, flour, and cinnamon. Add apple slices and toss until coated.
  3. Let apples sit for 10 minutes to release juices.
Make the Crumb Topping
  1. Combine oats, brown sugar, and flour in a bowl.
  2. Add softened butter and rub into the dry ingredients until clumpy.
Roll Out the Crust
  1. Preheat oven to 375°F and grease a baking sheet.
  2. Roll out one disc of chilled dough into a rectangle slightly larger than the baking sheet.
  3. Transfer crust to the baking sheet, pressing into corners and trimming excess.
Add the Filling and Crumb Topping
  1. Pour apple filling over the crust and spread evenly.
  2. Scatter crumb topping over the filling.
Bake Until Golden
  1. Bake for 45 to 50 minutes until topping is golden and filling is bubbling.
  2. If topping browns too quickly, tent with aluminum foil.
Make the Homemade Caramel Sauce
  1. In a saucepan over medium heat, combine brown sugar and butter, stirring until melted.
  2. Carefully add half-and-half and stir until thickened.
  3. Remove from heat and stir in vanilla and salt.
Drizzle and Serve
  1. Drizzle caramel sauce over the cooled slab pie.
  2. Cut into squares and serve warm or at room temperature.

Notes

Use Granny Smith apples for tartness and the best texture. Keep everything cold when making the crust for a flaky result. Let the filling rest to improve texture.
