Introduction
When it comes to classic American desserts, apple pie holds a special place in the heart of every kitchen. But when you’re baking for a crowd, the traditional round pie can feel a bit small. Enter the Apple Slab Pie—a generously sized, sheet pan version of the iconic dessert that’s perfect for parties, potlucks, and family gatherings. With its flaky crust, juicy spiced apple filling, and inviting golden-brown top, apple slab pie is as beautiful as it is delicious. It combines homey comfort with practical volume, ensuring everyone gets a slice.
In this piece, we’ll dive deep into what makes the apple slab pie so special—from its roots in American baking to the best techniques for mastering it at home. We'll also walk through a full recipe and offer expert tips for achieving pie perfection every time.
What Is an Apple Slab Pie?
At its core, an apple slab pie is simply a larger, rectangular version of the traditional round apple pie. Instead of being baked in a standard 9-inch pie plate, it’s baked in a rimmed baking sheet, usually around 10x15 inches. This change in format allows for more slices and a higher crust-to-filling ratio, making it especially appealing to crust lovers. It’s thinner than a classic pie, which helps the filling cook evenly and makes it easier to cut and serve.
But apple slab pie is more than just scaled-up pie. The texture, structure, and presentation have their own unique charm. With more surface area, there's more opportunity for the crust to get golden and crisp. Plus, you can cut it into tidy bars or squares for a more casual, hand-held treat.
The History Behind the Slab Pie
Slab pies have their roots in rural and farming communities, where bakers often had to feed large families and gatherings with minimal fuss. The idea of pressing a pie into a rectangular sheet was both economical and efficient. It allowed for less filling per serving while maximizing yield and reducing baking time.
Apple, of course, is a classic American filling—celebrated for its versatility, availability, and comforting flavor. The apple pie has become symbolic of American tradition, often associated with holidays, celebrations, and cozy kitchen moments. Combining the practicality of the slab pie with the timeless flavor of apple filling makes this dessert both functional and deeply nostalgic.

Ingredients for a Perfect Apple Slab Pie
For the Crust:
3¾ cups all-purpose flour
1 tablespoon granulated sugar
1½ teaspoons salt
1½ cups (3 sticks) unsalted butter, cold and cubed
½ to ⅔ cup ice water
For the Apple Filling:
8 cups peeled, cored, and sliced apples (a mix of Granny Smith and Honeycrisp works well)
¾ cup granulated sugar
¼ cup light brown sugar
2 teaspoons ground cinnamon
¼ teaspoon nutmeg
¼ teaspoon salt
1 tablespoon lemon juice
3 tablespoons cornstarch or all-purpose flour (for thickening)
For Assembly:
1 egg, beaten with 1 tablespoon milk (for egg wash)
Coarse sugar for sprinkling (optional)
Step-by-Step Recipe
Step 1: Make the Dough
- In a large bowl, whisk together the flour, sugar, and salt.
- Cut in the cold butter with a pastry cutter or your fingers until the mixture resembles coarse crumbs.
- Gradually add ice water, stirring just until the dough begins to come together.
- Divide the dough in two, shape into discs, wrap in plastic wrap, and chill for at least 1 hour.
Step 2: Prepare the Filling
While the dough chills:
- In a large mixing bowl, combine the sliced apples, sugars, spices, salt, lemon juice, and thickener.
- Toss well and let sit for about 15–20 minutes so the flavors meld and the juices release.
Step 3: Assemble the Pie
- Preheat the oven to 400°F (200°C).
- Roll out one disc of dough into a rectangle about 1 inch larger than your 10x15-inch rimmed baking sheet.
- Fit the dough into the pan, pressing into corners and letting the excess hang over the edges.
- Spread the apple filling evenly over the crust.
- Roll out the second disc of dough and lay it over the apples. Trim and crimp the edges together.
- Cut a few slits on top for steam to escape, then brush with egg wash and sprinkle with sugar.
Step 4: Bake
- Bake for 35–45 minutes, until the crust is golden and the filling is bubbling.
- Let cool on a rack for at least 30 minutes before slicing and serving.
Tips for Success
- Use a mix of apples: Combining tart and sweet apples gives a more complex flavor and better texture.
- Don’t skip the chill: Keeping the dough cold prevents the crust from shrinking or becoming tough.
- Juice control: Allowing apples to sit with sugar before baking helps release excess moisture, reducing sogginess.
- Bake on a lower oven rack: This helps the bottom crust crisp up nicely.
- Cool before slicing: Giving the pie time to rest allows the filling to set and keeps the slices neat.
Flavor Variations
Caramel Apple Slab Pie: Drizzle caramel sauce over the apples before topping with crust.
Apple-Cranberry Slab Pie: Add 1 cup fresh or dried cranberries for a tart twist.
Dutch Apple Slab Pie: Replace the top crust with a brown sugar-oat crumble topping.
Maple Glaze: After baking, drizzle with a simple glaze made from powdered sugar and maple syrup.
How to Serve Apple Slab Pie
This pie is delicious warm, at room temperature, or even chilled. Serve it plain, dusted with powdered sugar, or with a scoop of vanilla ice cream or a dollop of whipped cream. It's the kind of dessert that works equally well for a casual brunch or a festive dinner.
And because it slices so neatly, it's perfect for serving buffet-style or packaging up for gifts or bake sales.
Storage and Make-Ahead Tips
Store leftovers: Cover tightly and refrigerate for up to 4 days.
Freeze: Wrap baked and cooled pie tightly in plastic and foil; freeze for up to 3 months. Thaw overnight in the fridge.
Make ahead: You can assemble the pie a day ahead and refrigerate it before baking. Add the egg wash just before it goes in the oven.
