  • Author: Naomi
  • Total Time: 1 hr

Description

Apple Slab Pie is a larger, sheet-pan version of the classic dessert—perfect for serving a crowd. With a flaky crust, sweet cinnamon-spiced apples, and a golden finish, it’s a must for holidays, potlucks, and fall feasts!


Ingredients

Scale

For the crust:

  • 2 refrigerated pie crusts (or homemade, rolled out to fit a 15×10-inch jelly roll pan)

For the filling:

  • 6 cups thinly sliced peeled apples (Granny Smith, Honeycrisp, or a mix)

  • ¾ cup granulated sugar

  • ¼ cup brown sugar

  • ¼ cup all-purpose flour

  • 1½ tsp ground cinnamon

  • ¼ tsp nutmeg

  • 1 tbsp lemon juice

For the topping:

  • 1 egg, beaten (for egg wash)

  • 1 tbsp coarse sugar (optional)

  • Optional: vanilla glaze (powdered sugar + milk)


Instructions

1️⃣ Preheat oven: Set to 375°F (190°C). Lightly grease or line a 15×10-inch jelly roll pan with parchment paper.

2️⃣ Prepare crust: Roll out pie crusts and press into the bottom and up the sides of the pan, trimming excess.

3️⃣ Make the filling: In a large bowl, combine apples, sugars, flour, cinnamon, nutmeg, and lemon juice. Toss to coat evenly.

4️⃣ Assemble: Spread apple mixture evenly over the crust. Roll out and lay the second crust on top, or cut into strips for a lattice pattern. Seal edges and crimp.

5️⃣ Brush and bake: Brush top crust with beaten egg and sprinkle with coarse sugar. Bake for 35–40 minutes, or until crust is golden and filling is bubbly.

6️⃣ Cool and serve: Let cool slightly before slicing. Drizzle with glaze if desired.

Notes

  • Perfect served warm with vanilla ice cream.

  • Can be made a day ahead and reheated.

  • Try adding chopped pecans or raisins to the filling for variation.
