Introduction: Slab Pie, but Make It Apple
Apple slab pie is the dessert you didn’t know you were missing—until now. Imagine everything you love about classic apple pie, but in a larger, crowd-friendly format that’s easier to slice, serve, and enjoy. Unlike traditional round pies, slab pies are baked in a rectangular sheet pan, making them perfect for potlucks, holidays, or any gathering where a single slice just isn’t enough.
This version takes the familiar flavors of cinnamon-spiced apples and nestles them between two layers of buttery, flaky crust. The result? A nostalgic, golden, gooey dessert that disappears fast. You’ll love how simple it is to prep, how stunning it looks straight out of the oven, and how easy it is to adapt for any season or flavor combo.
The magic of this dessert lies in its layers. Between a homemade shortcrust pastry and spiced fruit filling, every bite balances sweet, tart, and buttery. According to Wikipedia’s guide to shortcrust pastry, this dough’s crumbly texture is ideal for pie crusts—especially when baked in larger slabs where the structure matters. For more crust success, our homemade pie crust tutorial walks you through tips like chilling your dough and working with cold butter.
If you’re someone who loves apple desserts or is planning to bake for a crowd, slab pies offer an unbeatable combination of ease and elegance. Once you try this apple version, you’ll wonder why you ever settled for one small pie to feed many. This is sheet pan baking at its most delicious.
Why Apple Slab Pie Works
What makes an apple slab pie so special isn’t just the generous size—it’s the texture, flavor, and convenience all wrapped into one buttery crust. By spreading the filling thinly across a sheet pan, you get more balanced bites of flaky pastry and tender cinnamon apples in every square.
The filling uses a mix of Granny Smith and Honeycrisp apples, offering a sweet-tart combo that holds up well in baking. Each slice is laced with cinnamon, nutmeg, and a splash of lemon juice, ensuring brightness and warmth without being overly sweet. Apple pie has long been an American classic, and this slab version makes it even easier to share.
The real win? This dessert is ideal for crowds. Whether it’s for a holiday dinner or a fall gathering, slab pie slices cleanly and serves 12–16 guests with ease.

Step-by-Step: How to Make Apple Slab Pie
Step 1: Prepare the dough by cutting cold butter into a flour, salt, and sugar mixture. Slowly add ice water just until it comes together. Divide, flatten into disks, wrap, and chill.
Step 2: Preheat oven to 375°F (190°C). Lightly grease or line a 10×15-inch jelly roll pan with parchment.
Step 3: Mix the apple filling with sugars, flour, spices, lemon juice, and vanilla. Toss until evenly coated.
Step 4: Roll out one dough disk to fit the pan, including the edges. Transfer and press into the corners.
Step 5: Spread the apple filling evenly. Dot with small pieces of butter.
Step 6: Roll out the second dough disk and lay over the top. Trim edges, seal by crimping, and cut slits for steam to escape.
Step 7: Brush the top with a beaten egg and sprinkle with coarse sugar if desired.
Step 8: Bake for 40–45 minutes until golden brown and bubbly. Cool completely before slicing into squares.

Pro Tips for the Perfect Crust
- Keep the butter cold – It should be visible in the dough to create flakes.
- Don’t overwork – Mix just until it holds together.
- Rest the dough – Chilling helps relax gluten and firms up the butter.
- Bake on a lower rack – Ensures the bottom crust sets and doesn’t get soggy.
- Brush with egg wash – Gives that golden bakery-style finish.
