Kitchen Equipment

  • Pastry brush

How to Make Apple Slab Pie

Step 1: Prepare the Pie Dough

In a large bowl, combine the flour, salt, and sugar.

Add the cold butter cubes.

Using a pastry cutter or your fingertips, work the butter into the flour until the mixture resembles coarse crumbs with pea-sized pieces of butter remaining.

Gradually add ice water, one tablespoon at a time, mixing just until the dough comes together.

Divide the dough into two equal portions.

Shape each into a rectangle, wrap in plastic wrap, and refrigerate for at least one hour.

Step 2: Prepare the Apple Filling

Peel, core, and thinly slice the apples.

Place them in a large bowl.

Add:

  • Granulated sugar
  • Brown sugar
  • Cinnamon
  • Nutmeg
  • Cloves
  • Cornstarch
  • Lemon juice
  • Vanilla extract
  • Salt

Mix until every apple slice is evenly coated.

Let the mixture rest for about 15 minutes so the flavors develop.

Step 3: Roll Out the Bottom Crust

Preheat your oven to 375°F (190°C).

Lightly flour your work surface.

Roll one portion of dough into a rectangle slightly larger than your baking pan.

Carefully transfer the dough into a greased jelly roll pan, pressing it gently into the corners.

Trim any excess dough if needed.

Step 4: Add the Filling

Spread the apple mixture evenly over the bottom crust.

Distribute the slices evenly to ensure consistent baking.

Avoid piling the filling too high, as this can make slicing difficult.

Step 5: Add the Top Crust

Roll out the second rectangle of dough.

Carefully place it over the apples.

Trim and crimp the edges to seal.

Cut several small slits across the top to allow steam to escape during baking.

Step 6: Brush with Egg Wash

Whisk together the egg and milk.

Brush the mixture evenly over the top crust.

Sprinkle with coarse sugar for an extra crisp, sparkling finish.

Step 7: Bake

Bake for 40–50 minutes, or until:

  • The crust is deep golden brown
  • The filling is bubbling through the vents
  • The apples are tender

If the edges brown too quickly, loosely cover them with aluminum foil.

Step 8: Cool Before Slicing

Allow the slab pie to cool for at least one hour.

Cooling helps the filling set, making cleaner slices.

Serve warm or at room temperature.

Tips for a Perfect Flaky Crust

Keep Everything Cold

Cold butter is essential for creating flaky layers.

If your kitchen is warm, chill the dough again before rolling.

Don’t Overwork the Dough

Mix only until the dough comes together.

Overmixing develops gluten, making the crust tough instead of tender.

Chill Before Baking

After assembling the pie, refrigerate it for 15–20 minutes before baking.

This helps the butter stay cold and improves the crust’s texture.

Use Fresh Apples

Fresh, firm apples hold their shape better during baking and create a more appealing filling.

Delicious Variations

This recipe is easy to customize.

Caramel Apple Slab Pie

Drizzle caramel sauce over the apple filling before adding the top crust.

The caramel melts into the apples for an extra indulgent dessert.

Apple Cranberry Slab Pie

Add one cup of fresh or frozen cranberries for a sweet-tart flavor that’s perfect for the holidays.

Maple Apple Pie

Replace part of the granulated sugar with pure maple syrup for a warm, rich sweetness.

Streusel-Topped Apple Slab Pie

Instead of a top crust, sprinkle a buttery streusel made with flour, brown sugar, butter, and cinnamon over the filling.

Bake until golden and crisp.

Serving Suggestions

Apple slab pie tastes wonderful on its own, but it’s even better with classic toppings.

Try serving it with:

  • Vanilla ice cream
  • Fresh whipped cream
  • Salted caramel sauce
  • Cinnamon ice cream
  • Vanilla custard
  • Sharp cheddar cheese for a traditional pairing

It’s delicious served warm, at room temperature, or even chilled.

Storage Instructions

Cover leftover pie tightly with plastic wrap or transfer it to an airtight container.

Store at room temperature for up to 2 days or refrigerate for up to 5 days.

Freezing Instructions

Apple slab pie freezes very well.

Wrap individual slices or the entire cooled pie tightly in plastic wrap and aluminum foil.

Freeze for up to 3 months.

Thaw overnight in the refrigerator before reheating.

Reheating Tips

Warm slices in a 325°F (163°C) oven for about 10–15 minutes.

For quick reheating, microwave individual slices for 20–30 seconds.

Oven reheating helps maintain the crust’s crispness.

Frequently Asked Questions

What is a slab pie?

A slab pie is simply a large rectangular pie baked in a sheet pan instead of a round pie dish. It’s ideal for serving larger groups and is easier to cut into evenly sized portions.

Can I use store-bought pie crust?

Yes. Refrigerated pie crusts can save time and still produce a delicious dessert. Homemade crust, however, typically offers a flakier texture and richer flavor.

Which apples should I avoid?

Very soft apples can become mushy during baking. Choose firm varieties that hold their shape well.

Why is my filling watery?

Too much liquid or not enough thickener can cause a runny filling. Cornstarch helps absorb the apple juices and creates a thick, sliceable filling.

Can I prepare this pie ahead of time?

Absolutely. You can assemble the pie a day in advance, cover it, and refrigerate until you’re ready to bake.
