Apple Slab Pie Recipe Smitten Kitchen: Rustic Sheet Pan Dessert for a Crowd

This sheet pan version of classic apple pie simplifies dessert for a crowd without sacrificing an ounce of flavor. I’ve adapted the technique to create a rustic, free-form pie that bakes evenly and serves effortlessly.

The beauty of this approach lies in its simplicity. A single crust covers a generous layer of spiced apples, all baked on a sheet pan for easy slicing and serving. No fuss with pie dishes or intricate lattice work.

What emerges from the oven is a golden, flaky crust encasing tender, cinnamon-spiced apples that hold their shape. The edges caramelize slightly, adding depth to every bite.

Ideal for gatherings, potlucks, or a weekend baking project. This method delivers professional results with minimal effort.

Ingredients for Apple Slab Pie Recipe Smitten Kitchen

A rustic sheet pan pie with flaky crust and spiced apples for easy serving.

The crust demands cold, high-quality butter—Plugrá or Kerrygold deliver superior flakiness. Use King Arthur flour for consistent results; its higher protein content handles the sheet pan’s larger surface without toughening. For apples, Granny Smiths hold structure best, but a mix with Honeycrisp adds sweetness. Source from farmers markets when in season for peak flavor and texture.

No Granny Smiths? Braeburn or Jonathan apples work well, though they soften more. Swap brown sugar for maple syrup at a 1:1 ratio if needed, but reduce other liquids slightly. Out of cornstarch? Instant tapioca at half the amount thickens similarly. The vanilla must be pure extract—imitation lacks depth. For a richer crust, replace 2 tbsp butter with cream cheese.

The unbaked slab pie can rest 1 hour in the fridge before baking. Store leftovers at room temperature for 2 days or refrigerate for 5 days. Rewarm slices in a 300°F oven for 10 minutes to restore the crust’s crispness. Freeze the entire baked pie for up to 3 months.

Step-by-Step Instructions for Apple Slab Pie

This method ensures a flaky crust and perfectly set filling every time.

Step 1: Prepare the Pie Crust

In a large bowl, combine the 3.5 cups all-purpose flour, 0.25 cup granulated sugar, and 1 tsp salt. I like to whisk these dry ingredients first to ensure even distribution.

Add the 1.25 cups cold, cubed unsalted butter and work it into the flour mixture using a pastry cutter or your fingers. The texture should resemble coarse crumbs with pea-sized butter pieces visible. This creates the flaky layers in your crust.

Gradually add the 0.5 cup ice water, 1 tablespoon at a time, mixing just until the dough comes together. Don’t overwork it—visible butter streaks are good. Divide the dough into two equal portions, flatten into discs, and chill for 1 hour.

Step 2: Prepare the Apple Filling

Peel, core, and thinly slice the 3 lb Granny Smith apples. I aim for ⅛-inch thick slices for even cooking. Toss them immediately with 1 tbsp lemon juice to prevent browning.

In a large bowl, combine the apples with 0.75 cup brown sugar, 1.5 tsp ground cinnamon, 0.25 tsp ground nutmeg, 1 tsp vanilla extract, and 2 tbsp cornstarch. The cornstarch will thicken the natural juices as the pie bakes.

Let the mixture sit for 15 minutes while you roll out the crust. This gives the apples time to release some juices and the sugar time to begin drawing out their natural moisture.

Step 3: Assemble the Slab Pie

On a lightly floured surface, roll one dough disc into a rectangle slightly larger than your sheet pan (typically 10×15 inches). Transfer to the pan, letting excess dough hang over the edges.

Spread the apple mixture evenly over the crust, leaving a 1-inch border all around. Drizzle any accumulated juices from the bowl over the apples—they contain valuable flavor and will thicken as the pie bakes.

Roll out the second dough disc to the same size and place it over the filling. Crimp the edges to seal, then cut several 1-inch slits in the top crust to allow steam to escape.

Step 4: Bake to Golden Perfection

Preheat your oven to 375°F. Brush the top crust with 2 tbsp heavy cream and sprinkle evenly with 2 tbsp coarse sugar. This creates a beautiful, crisp finish.

Bake for 45-50 minutes until the crust is deep golden brown and the filling is bubbling through the vents. If the edges brown too quickly, tent them with foil.

Let the pie cool completely in the pan on a wire rack for at least 2 hours before slicing. This allows the filling to set properly—cutting too soon will result in a runny filling.

Wine and Beer Pairings for These Flavors

Sweet Wine Pairings

For this dessert, I love a Moscato d’Asti from Italy—its light effervescence and peach-apricot notes complement the spiced apples beautifully. The gentle sweetness balances the tartness of Granny Smiths without overpowering. 🍷

Dessert Whites

A Late Harvest Riesling from Washington State offers honeyed sweetness with crisp acidity that cuts through the buttery crust. I recommend Chateau Ste. Michelle for consistent quality at a good price point.

Rich Red Option

Surprisingly, a chilled Brachetto d’Acqui works wonderfully. Its strawberry-rose flavors and slight fizz create a refreshing contrast. Serve at 50-55°F for best results.

Beer Choices

For beer lovers, a Belgian Tripel like Westmalle has enough fruitiness and spice to stand up to the pie. The higher alcohol content (around 9% ABV) helps balance the sweetness.

Non-Alcoholic Pairing

Sparkling apple cider—preferably Martinelli’s—echoes the pie’s flavors while adding a festive touch. The bubbles cleanse your palate between bites. ✨

Coffee Accompaniment

Serve with a cup of dark roast coffee to provide a bittersweet counterpoint. I prefer Peet’s Major Dickason’s Blend for its boldness against the dessert’s sweetness.
