Home-baked Apple Slab Pie Recipe tastes like a bakery-style apple pie with extra flaky corners, caramelized edges, and a buttery crust that makes the whole kitchen smell like fall. This big-batch dessert suits potlucks, holidays, bake sales, and any time you want pie for a crowd in about 2 hours total. I grew up in a house where dessert counted as a love language, so this kind of tray-baked pie feels like a hug on a sheet pan.
Why You Should Try This Home-baked Apple Slab Pie Recipe
This apple slab pie feeds a crowd without fussy individual crusts or tiny pie tins. You roll one big crust, pile on the apples, top it, and bake a gorgeous golden tray of pie that slices like brownies.
The crust stays flaky, the apples stay tender but not mushy, and the juices thicken into a glossy cinnamon-spiced filling. You also get that magical corner-piece effect, where the edges turn extra caramelized and slightly chewy.

Ingredients You’ll Need
For the crust
You can use homemade crust or a smart shortcut with store-bought dough. I list both so you can choose your own adventure.
- 3 cups all-purpose flour (scoop and level)
- 1 tablespoon granulated sugar
- 1 teaspoon fine sea salt
- 1 cup (2 sticks) cold unsalted butter, cut into small cubes
- 1 large egg, cold
- 1/2 cup ice water, plus 1 to 2 tablespoons more as needed
- 1 teaspoon apple cider vinegar or white vinegar
Shortcut option:
Use 2 boxes of refrigerated pie crust (usually 4 crusts total) or 2 sheets of good-quality puff pastry. I like Trader Joe’s or Pillsbury for pie crust and Pepperidge Farm for puff pastry.
For the apple filling
- 3 1/2 to 4 pounds apples, peeled, cored, and sliced about 1/4 inch thick
- Great combo: half tart (Granny Smith, Pink Lady) and half sweet (Honeycrisp, Fuji, Gala)
- 3/4 to 1 cup granulated sugar (use 3/4 cup for sweeter apples, 1 cup for very tart apples)
- 1/3 cup light brown sugar, packed
- 1/4 cup cornstarch or 1/3 cup all-purpose flour (cornstarch gives a clearer, glossier filling)
- 1 1/2 to 2 teaspoons ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon ground allspice (optional but tasty)
- 1/4 teaspoon fine sea salt
- 2 teaspoons lemon juice
- 1 teaspoon vanilla extract
- 2 tablespoons unsalted butter, cut into tiny pieces
For the egg wash and topping
- 1 large egg
- 1 tablespoon milk or heavy cream
- 1 to 2 tablespoons coarse sugar or turbinado sugar for sprinkling
- Optional: a light dusting of powdered sugar after baking
Equipment list
- 13 x 18 inch rimmed baking sheet (standard half sheet pan)
- Parchment paper
- Rolling pin
- Large mixing bowls
- Pastry cutter or two forks (if you make the crust by hand)
- Plastic wrap
- Small bowl and pastry brush
- Sharp knife or pizza cutter
- Cooling rack
Tips & Tricks
- Chill the butter and keep it cold so the crust bakes up flaky and tender.
- Use a mix of tart and sweet apples so the filling tastes balanced and not flat.
- Slice apples evenly so they cook at the same rate and avoid crunchy surprises.
- Toss the apples with sugar and spices, then taste a slice and adjust sweetness before you add cornstarch.
- Line the pan with parchment so you lift slices cleanly and avoid stuck-on caramel.
- Roll the crust slightly larger than the pan so you tuck and crimp without stretching the dough.
- Vent the top crust with slits or a lattice so steam escapes and the filling thickens instead of bubbling over.
- Chill the assembled pie 15 to 20 minutes before baking so the crust holds its shape.
- Bake on the lower-middle rack so the bottom crust browns and does not turn soggy.
- Let the slab pie cool at least 45 to 60 minutes so the filling sets and slices neatly.
How to Make Home-baked Apple Slab Pie Recipe
Step 1: Mix the crust dough
In a large bowl, whisk the flour, sugar, and salt. Add the cold butter cubes and cut them into the flour with a pastry cutter or two forks until you see pea-size bits of butter.
In a small bowl, whisk the egg, ice water, and vinegar. Pour this mixture into the flour and butter, then stir until the dough starts to clump.
Use your hands to press the dough together in the bowl. If it feels dry and crumbly, sprinkle in 1 tablespoon of ice water at a time until it holds together in a rough ball.
Step 2: Chill and divide the dough
Turn the dough onto a lightly floured surface and gently knead just until it forms a smooth mass. Do not overwork it, or the crust turns tough.
Shape the dough into a rectangle and cut it into two pieces, with one slightly larger for the bottom crust. Wrap each piece tightly in plastic wrap.
Flatten each wrapped piece into a thick rectangle. Chill the dough in the fridge for at least 1 hour, or up to 2 days.
Step 3: Prep the apples
Peel, core, and slice the apples about 1/4 inch thick. Try to keep the slices similar in size.
Place the apples in a large bowl. Add granulated sugar, brown sugar, cinnamon, nutmeg, allspice, and salt.
Toss until the apples coat evenly. Add lemon juice and vanilla, then toss again.
Sprinkle cornstarch over the apples and toss until no dry spots remain. Set the bowl aside while you roll the crust so the apples release a bit of juice.
Step 4: Roll the bottom crust
Line your half sheet pan with parchment paper. Lightly flour your work surface and rolling pin.
Take the larger piece of dough from the fridge and place it on the floured surface. Roll it into a large rectangle slightly bigger than your pan, about 15 x 20 inches.
Gently roll the dough around the rolling pin, then unroll it over the pan. Press it into the corners and sides without stretching the dough.
Let the excess dough hang over the edges for now. You will trim and crimp later.
Step 5: Fill the slab pie
Give the apples a quick toss again. Pour them into the crust-lined pan and spread them into an even layer.
Scrape any juices and spices from the bowl over the apples. Dot the top with the small pieces of butter.
Try to keep the apple layer level so the top crust sits evenly. This helps the pie bake uniformly.
Step 6: Roll and place the top crust
Take the second piece of dough from the fridge. Roll it into a rectangle just slightly larger than the pan.
Carefully roll the dough around the rolling pin, then unroll it over the apples. Adjust it so it covers the filling completely.
Trim the excess dough from the edges, leaving about 1/2 inch overhang from both top and bottom crusts. Fold the edges together and tuck them inward to seal.
Crimp the edges with your fingers or a fork. Aim for a tight seal so juices stay mostly inside.
Step 7: Vent, chill, and egg wash
Use a sharp knife to cut several slits across the top crust. You can cut simple parallel slashes or a small pattern.
Place the assembled pie in the fridge for 15 to 20 minutes while you heat the oven. This quick chill helps the crust hold its shape and stay flaky.
Preheat the oven to 400°F. In a small bowl, whisk the egg and milk.
Brush the top crust and edges with the egg wash. Sprinkle coarse sugar over the top for crunch and sparkle.
Step 8: Bake the apple slab pie
Place the pan on the lower-middle rack of the oven. Bake at 400°F for 20 minutes.
Reduce the temperature to 350°F and continue baking 25 to 35 minutes, until the crust looks deep golden and the filling bubbles through the vents. If the edges brown too quickly, tent them loosely with strips of foil.
The total bake time usually lands between 45 and 55 minutes. Trust your eyes and nose more than the clock, and pull the pie when the top looks richly golden and the bubbling appears thick and syrupy.
Step 9: Cool and slice
Place the pan on a cooling rack. Let the apple slab pie cool at least 45 to 60 minutes.
This rest time allows the filling to thicken so slices hold their shape. If you cut too soon, the juices run and the slices slide around.
Slice the slab pie into squares or rectangles. Serve warm, room temperature, or slightly chilled.
Step 10: Optional glaze or topping
If you want a simple glaze, whisk 1/2 cup powdered sugar with 1 to 2 tablespoons milk and a tiny splash of vanilla. Drizzle it over the cooled pie in thin lines.
You can also dust the top lightly with powdered sugar right before serving. That touch gives it a bakery-style look with almost no effort.
Serve slices plain or with a scoop of vanilla ice cream or a spoonful of whipped cream. Kids usually vote for ice cream, adults often sneak both.
What to Serve with Home-baked Apple Slab Pie Recipe
This Home-baked Apple Slab Pie Recipe pairs nicely with vanilla ice cream, cinnamon ice cream, or a dollop of lightly sweetened whipped cream. You can also serve it with a mug of hot coffee, chai, or spiced herbal tea for a cozy dessert moment. If you plan a party, set up a little topping bar with ice cream, caramel sauce, chopped nuts, and mini chocolate chips.

Storage Options
- Let the apple slab pie cool completely, then cover the pan tightly with foil or transfer slices to an airtight container and keep in the fridge for up to 4 days.
- Freeze individual slices on a parchment-lined tray until firm, then wrap each slice in plastic and store in a freezer bag for up to 2 months.
- Reheat single slices in a 350°F oven or toaster oven for 8 to 10 minutes until warm and crisp at the edges.
- Warm larger portions in a 325°F oven, covered loosely with foil, for 15 to 20 minutes, then uncover for a few minutes so the top regains some crunch.
