Ingredients (Serves 12–16)
For the Crust:
-
4 cups (500 g) all-purpose flour
-
1 tsp salt
-
1 tbsp sugar
-
1½ cups (340 g) cold unsalted butter, cubed
-
¾–1 cup ice water
For the Apple Filling:
-
8–10 medium apples (Granny Smith, Honeycrisp, or a mix)
-
¾ cup granulated sugar
-
¼ cup brown sugar
-
2 tsp ground cinnamon
-
¼ tsp nutmeg
-
¼ tsp salt
-
¼ cup cornstarch
-
1 tbsp lemon juice
-
1 tsp vanilla extract
Optional Glaze:
-
1 cup powdered sugar
-
1–2 tbsp milk
-
½ tsp vanilla extract
Step 1: Prepare the Pie Dough
-
In a large bowl, whisk together flour, salt, and sugar.
-
Add cold cubed butter and cut it in using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
-
Gradually add ice water, 1 tablespoon at a time, mixing until the dough just comes together.
-
Divide dough into two portions (one slightly larger for the bottom crust), wrap in plastic, and refrigerate for at least 1 hour.
💡 Tip: Cold butter is the secret to a flaky crust.
Step 2: Prepare the Apple Filling
-
Peel, core, and thinly slice the apples.
-
In a large bowl, combine apples with granulated sugar, brown sugar, cinnamon, nutmeg, salt, cornstarch, lemon juice, and vanilla.
-
Toss until apples are evenly coated.
Let the mixture sit for 10–15 minutes to allow the flavors to blend.
Step 3: Roll Out the Bottom Crust
-
Preheat oven to 375°F (190°C).
-
Roll out the larger dough portion into a rectangle large enough to fit a 10×15-inch (or similar size) rimmed sheet pan.
-
Carefully transfer the dough into the pan, pressing gently into corners and up the sides.
Step 4: Add the Apple Filling
Spread the apple mixture evenly over the crust. Make sure the apples are distributed in an even layer for consistent baking.
Step 5: Add the Top Crust
-
Roll out the remaining dough into a rectangle.
-
Place it over the apple filling.
-
Trim excess dough and crimp edges to seal.
-
Cut small slits in the top to allow steam to escape.
💡 Optional: Brush the top with egg wash and sprinkle with coarse sugar for a golden, bakery-style finish.
Step 6: Bake
Bake for 40–50 minutes, or until the crust is golden brown and the filling is bubbling.
If the edges brown too quickly, cover loosely with foil.
Allow the pie to cool for at least 1 hour before slicing to let the filling set properly.
Step 7: Optional Glaze
Mix powdered sugar, milk, and vanilla until smooth. Drizzle lightly over the cooled pie for a sweet finishing touch.
Tips for the Perfect Apple Slab Pie
-
Use Mixed Apples: Combining tart and sweet apples gives deeper flavor.
-
Slice Apples Evenly: Thin slices cook more uniformly.
-
Don’t Skip the Resting Time: Cooling helps the filling thicken.
-
Avoid Overworking Dough: This keeps the crust tender and flaky.
-
Line Pan with Parchment (Optional): Makes removal easier.
Variations
