Step-by-Step Instructions

Step 1: Make the Pie Dough

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

Cut the cold butter into the flour until the mixture resembles coarse crumbs.

Gradually add ice water until the dough comes together.

Divide into two portions, wrap in plastic wrap, and refrigerate for at least one hour.

Step 2: Prepare the Apple Filling

Peel, core, and slice the apples into even slices.

In a large bowl, combine:

Apples
Granulated sugar
Brown sugar
Flour
Cinnamon
Nutmeg
Vanilla
Lemon juice
Melted butter

Mix until every apple slice is evenly coated.

Allow the mixture to rest for 10–15 minutes.

Step 3: Roll Out the Bottom Crust

Lightly flour your work surface.

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

Carefully transfer it into a greased 10×15-inch jelly roll pan.

Press gently into the corners.

Trim excess dough if necessary.

Step 4: Add the Filling

Spread the apple mixture evenly over the crust.

Avoid piling the filling too high in the center.

Distribute the apples evenly for consistent baking.

Step 5: Add the Top Crust

Roll the second dough portion into another rectangle.

Place it over the apples.

Trim and seal the edges by pressing gently.

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

Step 6: Brush with Egg Wash

Whisk together:

One egg
One tablespoon milk

Brush evenly over the top crust.

Sprinkle with coarse sugar for a beautiful golden finish if desired.

Step 7: Bake

Bake in a preheated oven at 375°F (190°C) for 40–50 minutes, or until:

The crust is golden brown
The filling is bubbling
The apples are tender when pierced

If the edges brown too quickly, loosely cover them with aluminum foil during the last 15–20 minutes of baking.

Tips for the Best Apple Slab Pie

Keep the Butter Cold

Cold butter creates flaky layers in the crust.

Don’t Overwork the Dough

Mix only until the dough comes together to avoid a tough crust.

Slice Apples Evenly

Uniform slices ensure the apples cook at the same rate.

Taste Your Apples

Sweeter apples may require slightly less sugar, while tart apples may benefit from a little more.

Let the Pie Cool

Allow the pie to cool for at least 1–2 hours before slicing. This helps the filling set and makes serving easier.

Delicious Variations

Caramel Apple Slab Pie

Drizzle caramel sauce over the filling before adding the top crust for an extra layer of sweetness.

Dutch Apple Slab Pie

Replace the top crust with a buttery streusel topping made from flour, butter, brown sugar, and oats.

Apple Cranberry Slab Pie

Add one cup of fresh or frozen cranberries to the filling for a bright, tart flavor.

Apple Pecan Slab Pie

Mix chopped pecans into the filling or sprinkle them over a streusel topping for added crunch.

Maple Apple Pie

Replace part of the granulated sugar with pure maple syrup for a rich autumn flavor.

Serving Suggestions

Apple slab pie is delicious on its own, but you can make it even more special by serving it with:

Vanilla ice cream
Fresh whipped cream
Salted caramel sauce
Cinnamon ice cream
Chopped toasted pecans
A drizzle of maple syrup

Serve slightly warm for the best flavor and texture.

Storage Tips

Room Temperature

Cover the pie loosely and store for up to 2 days if your kitchen is cool.

Refrigerator

Store covered in the refrigerator for up to 5 days.

Freezer

Wrap individual slices or the entire pie tightly and freeze for up to 3 months.

Thaw overnight in the refrigerator before reheating.

How to Reheat

For the best texture, warm slices in a 325°F (163°C) oven for about 10–15 minutes.

If using a microwave, heat in short intervals until warmed through. Keep in mind that the crust may become softer than when reheated in the oven.

Common Mistakes to Avoid

Using warm butter for the crust
Overfilling the pie
Forgetting to vent the top crust
Baking at too high a temperature
Cutting into the pie before it has cooled
Using apples that become overly soft during baking

Avoiding these mistakes helps ensure a flaky crust and a well-set filling.

Frequently Asked Questions

Can I make apple slab pie ahead of time?

Yes. You can bake it a day in advance and store it covered. Many people find the flavors deepen after resting overnight.

Do I have to peel the apples?

Peeling is recommended for the most tender filling, but if you prefer a more rustic texture, you can leave the skins on after washing the apples thoroughly.

Can I use store-bought pie crust?

Yes. Store-bought pie dough can save time and still produce a delicious dessert, though homemade crust often has a richer flavor and flakier texture.

Why is my apple pie watery?

Excess moisture can result from very juicy apples or insufficient thickener. Letting the filling rest before baking and allowing the pie to cool completely before slicing helps the filling set.

Can I freeze unbaked apple slab pie?

Yes. Assemble the pie, wrap it tightly, and freeze before baking. When ready to bake, place it in the oven directly from frozen and add extra baking time until the crust is golden and the filling is bubbling.
