What Is an Apple Slab Pie?
An apple slab pie is simply a supersized apple pie baked in a rectangular sheet pan. Instead of a round pie that serves 8, you get a generous tray that can feed up to 20 — without losing any of the flaky crust or juicy apple filling we all love.
It’s practical, beautiful, and perfect for slicing into neat squares for parties, bake sales, or holiday dessert tables.

What It Tastes Like
Every bite gives you the classic flavor of homemade apple pie — sweet-tart apples, warm cinnamon and nutmeg, and a buttery, flaky crust. Because it’s a slab pie, there’s a wonderful crust-to-filling ratio in each square… more flaky pastry in every mouthful!

- 3 tablespoons cornstarch
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- ¼ teaspoon ground allspice
- ⅛ teaspoon salt

Tools You’ll Need

Ingredient Tips & Variations
- Apple Choices: Granny Smith for tartness, Honeycrisp for sweetness, or a mix for balance.
- Spice Swap: Add a pinch of ginger or cardamom for a twist.
- Shortcut Crust: Use refrigerated pie dough if you’re short on time.
- Topping Idea: Sprinkle coarse sugar over the egg wash for sparkle and crunch.
Step-by-Step Instructions
- Make the Crust – In a large bowl, whisk flour, sugar, and salt. Cut in the cold butter until you have pea-sized pieces. Slowly add ice water, mixing until dough just comes together. Divide into two disks, wrap in plastic, and chill for at least 1 hour.
- Prepare the Filling – Toss diced apples with lemon juice, sugar, cornstarch, cinnamon, nutmeg, allspice, and salt. Set aside.
- Assemble – Roll out one disk of dough to fit the sheet pan, letting excess hang over edges. Spread apple filling evenly. Roll out second disk and place over apples. Trim, fold, and crimp edges.
- Add Topping – Brush with heavy cream or egg wash.
- Bake – Bake at 375°F (190°C) for 45–55 minutes, until crust is golden and filling is bubbling.
- Cool & Serve – Let cool for at least 30 minutes before slicing into squares.
Serving Suggestions
- A scoop of vanilla ice cream or cinnamon ice cream.
- Freshly whipped cream.
- A drizzle of caramel sauce for extra indulgence.
Tips for the Best Slab Pie
- Keep the butter cold – cold butter = flaky crust.
- Don’t skip chilling – chilled dough holds its shape better while baking.
- Watch the edges – if they brown too quickly, cover with foil strips.
Storage Instructions
- Room Temp: Covered, up to 2 days.
- Fridge: Up to 5 days, well wrapped.
- Freezer: Wrap tightly and freeze for up to 3 months. Thaw in fridge before reheating at 300°F.
