Why You’ll Love Apple Slab Pie
Apple slab pie is a favorite for many reasons. It’s practical, delicious, and surprisingly simple to make. Because it’s baked in a sheet pan, it cools evenly and slices neatly—no struggling with messy wedges. It also allows for a higher apple-to-crust ratio, which many people prefer.
The flavors are classic and comforting: tender apples, warm cinnamon, a hint of nutmeg, and a flaky crust that melts in your mouth. Whether served warm or at room temperature, apple slab pie always feels like home.

For the Crust:
- 4 cups all-purpose flour

- 10–12 medium apples (about 4–4.5 lbs), peeled and thinly sliced
- 3/4 cup granulated sugar
- 1/2 cup brown sugar
- 1/4 cup all-purpose flour
- 2 teaspoons ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon ground allspice (optional)
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
For Assembly:
- 1 large egg (for egg wash)

Kitchen Tools You’ll Need
- 10×15-inch or 10×18-inch rimmed baking sheet
- Large mixing bowl
- Rolling pin
- Pastry cutter or fork
- Sharp knife
- Parchment paper
- Pastry brush
Step-by-Step Instructions
Step 1: Make the Pie Dough
In a large bowl, whisk together the flour, sugar, and salt. Add the cold butter cubes and cut them into the flour using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized pieces of butter.
Gradually add ice water, a few tablespoons at a time, mixing just until the dough comes together. Divide the dough into two equal portions, shape into rectangles, wrap in plastic wrap, and refrigerate for at least 1 hour.
Step 2: Prepare the Apple Filling
In a large bowl, combine the sliced apples, granulated sugar, brown sugar, flour, cinnamon, nutmeg, allspice (if using), lemon juice, and vanilla extract. Toss until the apples are evenly coated. Set aside while you roll out the crust.
Step 3: Roll Out the Bottom Crust
Preheat your oven to 375°F (190°C). Line the baking sheet with parchment paper.
On a lightly floured surface, roll out one portion of dough into a rectangle slightly larger than your pan. Carefully transfer it to the prepared baking sheet, pressing it gently into the corners and up the sides.
Step 4: Add the Apple Filling
Spread the apple filling evenly over the bottom crust, making sure the apples are distributed in an even layer.
Step 5: Roll Out the Top Crust
Roll out the second portion of dough into a rectangle the same size as the pan. Place it over the apple filling. Trim any excess dough and crimp or press the edges together to seal.
Use a sharp knife to cut small slits in the top crust to allow steam to escape.
Step 6: Egg Wash
In a small bowl, whisk together the egg and milk (or water). Brush the egg wash evenly over the top crust. Sprinkle with coarse sugar if desired for extra crunch and sparkle.
Step 7: Bake
Bake for 40–50 minutes, or until the crust is golden brown and the filling is bubbling through the slits.
If the crust begins to brown too quickly, loosely cover with foil during the last 10 minutes.
Step 8: Cool Before Slicing
Remove the slab pie from the oven and let it cool for at least 30–45 minutes. This allows the filling to set and makes slicing much easier.
Best Apples for Slab Pie
For the best flavor and texture, use a mix of apples. Combining sweet and tart varieties creates depth and balance.
Great choices include:
- Granny Smith
- Honeycrisp
- Braeburn
- Fuji
- Jonagold
Avoid overly soft apples, as they can turn mushy during baking.
