Homemade Apple Slab Pie 
Apple Slab Pie is a large, rustic dessert perfect for feeding a crowd. It’s essentially a full-sheet apple pie with tender, spiced apple filling, buttery flaky crust, and a golden top. 🍎🥧
🥣 Ingredients
Pie Crust
-
2 batches of homemade or store-bought pie dough (enough for top and bottom crusts)
Apple Filling
-
8 cups peeled, cored, and sliced apples (Granny Smith or Honeycrisp)
-
¾ cup granulated sugar
-
¼ cup brown sugar
-
2 tablespoons all-purpose flour
-
1 teaspoon ground cinnamon
-
¼ teaspoon ground nutmeg
-
1 teaspoon lemon juice
-
1 teaspoon vanilla extract
Topping
-
1 egg, beaten (for egg wash)
-
2 tablespoons granulated sugar for sprinkling
👩🍳 Instructions
1️⃣ Prepare Oven
-
Preheat oven to 375°F (190°C).
-
Grease or line a rectangular baking sheet or 9×13-inch pan.
2️⃣ Make the Filling
-
In a large bowl, combine sliced apples, sugars, flour, cinnamon, nutmeg, lemon juice, and vanilla.
-
Toss until apples are evenly coated.
3️⃣ Assemble the Pie
-
Roll out one batch of dough and line the bottom of the baking pan.
-
Pour the apple filling evenly over the crust.
-
Roll out the second batch of dough and place it over the apples.
-
Trim excess dough and seal the edges.
-
Cut a few slits in the top crust to allow steam to escape.
4️⃣ Add Topping
-
Brush the top with beaten egg.
-
Sprinkle with granulated sugar for a sparkling finish.
5️⃣ Bake
-
Bake for 45–55 minutes, or until the crust is golden brown and filling is bubbling.
-
If the edges brown too quickly, cover with foil.
6️⃣ Cool
-
Let the pie cool for at least 30 minutes before slicing. This helps the filling set.
