Delicious Apple Slab Pie

Last Thanksgiving, my tiny apartment kitchen smelled like cinnamon and butter for three days straight. I had promised to bring dessert for twelve people, and regular pie plates just weren't going to cut it. That slab pie fed everyone with leftovers to spare, and now it's become my go-to for any gathering.

My grandmother always said the secret to great pie was confidence in your hands. She would pat the dough into pans freeform, never measuring, somehow knowing exactly how thick it should be. This recipe captures that spirit with enough structure to ensure success.

Ingredients

• All purpose flour: Creates the structure for your crust, with protein content that balances tenderness and strength
• Unsalted butter: Must be ice cold to create flaky layers, control the salt yourself
• Granny Smith and Honeycrisp apples: The tartness holds up beautifully against brown sugar and spices
• Cornstarch: Thickens the fruit juices so your bottom crust stays crisp, not soggy

Instructions

Mix the crust foundation:

Whisk flour, sugar, and salt in a large bowl until combined

Cut in the cold butter:

Work quickly with a pastry blender or your fingers until butter chunks are pea sized, keeping everything cold

Bring dough together:

Drizzle ice water while tossing gently, adding only enough so dough holds when squeezed

Shape and chill:

Divide dough into two unequal pieces, flatten into discs, wrap and refrigerate at least 30 minutes

Prepare the apple filling:

Toss sliced apples with both sugars, cinnamon, nutmeg, salt, cornstarch and lemon juice until coated

Line your pan:

Roll the larger dough disc and fit it into a 10x15 inch rimmed baking sheet, pressing into corners

Layer the apples:

Mound filling evenly over the crust, packing apples slightly as they will shrink during baking

Top and seal:

Roll remaining dough, place over apples, trim edges, pinch to seal and cut steam vents

Finish and bake:

Brush with egg wash, sprinkle sugar, bake at 400 degrees for 35 to 40 minutes until golden

Cool completely:

Let rest at least 30 minutes before slicing so filling sets properly

Save

That Thanksgiving slab pie disappeared in minutes, and my cousin asked for the recipe before she even finished her first slice. Something about rectangular servings feels more casual, more help yourself, more like home.

Making It Your Own

Swap pears for half the apples in autumn, or add cranberries for festive color. A splash of vanilla extract or bourbon in the filling makes it feel extra special.

Storage and Serving

This pie keeps beautifully at room temperature for two days, or refrigerate for up to five. Reheat individual squares in a 300 degree oven for that fresh baked taste.

Perfect Pairings

Vanilla bean ice cream melts into every crevice, while a sharp cheddar on the side pays homage to classic American pie traditions. Strong black coffee cuts through the sweetness beautifully.

• Try it slightly warmed with salted caramel sauce
• Aged gouda adds surprising sophistication
• Leftovers make an incredible breakfast the next day

Save

There is something deeply satisfying about feeding a room full of people from one enormous pie. Watch them go back for seconds.

Common Questions

→ What type of apples work best?

Granny Smith and Honeycrisk apples provide excellent results. The tartness balances the sugar, while both varieties hold their texture during baking. You can also use Braeburn, Jonathan, or a mix of several types.

→ Can I make the dough ahead?

Absolutely. Prepare the dough up to 2 days in advance, wrap tightly in plastic, and refrigerate. Let it soften slightly at room temperature for 15-20 minutes before rolling.

→ Why bake in a slab pan?

The large rectangular pan yields more servings than a traditional round pie and creates easier-to-serve squares. The shallow depth allows the crust to bake evenly while the filling cooks through properly.

→ How do I know when it's done?

The crust should be deep golden brown and you should see the filling bubbling actively through the steam vents. If the crust browns too quickly, tent with foil after 25 minutes.

→ Can I freeze this?

Yes, freeze the baked, cooled pie wrapped tightly for up to 3 months. Thaw overnight in the refrigerator, then reheat at 350°F for 15 minutes to refresh the crust.

→ What should I serve with it?

Warm slices pair wonderfully with vanilla ice cream or freshly whipped cream. A drizzle of caramel sauce adds extra richness. It's also delicious on its own, slightly warm.
