Instructions

Prepare the Pie Crust

  • Preheat the oven to 375°F and lightly grease a rimmed 9 x 13-inch baking sheet that has raised sides on all 4 corners of the pan.
  • Press 2 pie crusts together and roll them out until just a little larger than the baking dish.
  • Fit them into the bottom of the pan, allowing the edges to slightly overhang.

Prepare the Apple Filling

  • In a large bowl, combine apples, brown sugar, cinnamon, nutmeg, and cornstarch.
  • Stir until the apples are evenly coated.

Assemble the Pie

  • Spread the apple mixture over the crust and dot with butter.
  • Press together the remaining 2 pie crusts, roll them out and place on top of the filling. Trim and pinch edges to seal.
  • Whisk together egg and milk, then brush the top crust with the egg wash.

Bake the Pie

  • Cut slits in the pie top to allow steam to escape.
  • Bake for 35 to 40 minutes or until the crust is golden brown and the filling is bubbling.
  • Let the apple slab pie cool completely.

Glaze the Pie

  • To make the glaze, whisk together powdered sugar, ½ Tablespoon milk and vanilla until smooth. Whisk in more milk, if needed, to achieve a pourable consistency.
  • Drizzle the glaze over the cooled pie before slicing into squares.

Notes

Use firm apples: They hold their shape better during baking.
Seal the edges well: Prevents the filling from leaking out.
Let it cool fully: This helps the filling set and makes slicing easier.
Glaze just before serving: Keeps the topping fresh and glossy.
Don’t skip the cornstarch: It keeps the filling from getting too wet.
