This freezer-friendly, make-ahead apple slab pie is perfect for feeding a crowd at your party. Prep it ahead, keep it chilled in the fridge and bake it fresh just before your party. Better yet, you can freeze it and bake directly from frozen.
There is something just so fun and satisfying in cutting a square pie piece from an apple slab pie.
Even better, the pie tastes even better when you can do all the work in advance and just enjoy a fresh baked pie straight from your fridge or freezer.
Baking a pie from scratch tends to be one of the more intimidating things for beginner bakers. But this pie recipe is filled with all the tips you need to whip together a from-scratch pie crust and delicious apple filling in just minutes.
Why Slab Pie is Better
A classic round apple pie is one of the first things we think of when we picture "as American as apple pie."
Honestly though, I prefer a rectangular slab pie every time because:
- Easier to Roll: The pie crust is so much easier to roll out into a perfect rectangle than a circle.
- Fits in the Freezer Better: Rectangular things take up less space than circles in my freezer.
- Fun to Slice: I love square/rectangular pieces of pie! More flaky, buttery crust per serving.
- Easier to Cut More Servings: There actually isn't that much more pie in this recipe than a regular circle pie but the square shape is easier to slice into more servings for a party.
Apple pie is so easy to make because the list of ingredients is so basic and easy:
- Fresh Apples: I love to use Granny Smith.
- Fresh Orange and Lemon: These keep the pie from getting too sweet.

Prepare the Pie Crust
I love this butter pie crust recipe because not only can you make it in advance, but it actually works even better when you do!
The rest and chill time helps keep it nice and flaky in the oven.

The key to a flaky apple slab pie is all in chilling the pie crust.
Once you've rolled out the dough, fill the pie pan with the bottom crust like this:
Chill both the pie pan and the top crust in the fridge while you prepare the apple filling.
Prepare the Apple Filling
Peel and slice the apples. Place them in a large mixing bowl so it is easier to toss them in the sugar and spices.
Add the zest and juices of the orange and lemon, sugar, cinnamon, and nutmeg to the bowl and toss together with a spatula.
Pour the apple mixture into the prepared pie pan. It will look like a LOT of apples, but they will bake down in the oven.
Assemble and Bake the Pie
Place the top crust on the pie pan and crimp the edges together with a fork.
Use a paring knife to slice venting holes in the top.
TOP TIP: Place the fully assemble pie back into the fridge to chill while you preheat the oven. This lets the dough rest from all the handling and ensures the butter will stay nice and cold.
Preheat the oven to 375°F with a large baking stone or baking sheet turned upside down on the center rack.
The stone or baking sheet will help create an even baking surface so that the bottom of the slab pie will be nice and crispy.
Place the chilled slab pie directly on the preheated baking stone or baking sheet in the oven and bake for 45 minutes or until the filling is hot and bubbly and the crust is golden brown.
Make Ahead Instructions
There are several ways you can prep this apple slab pie ahead of time. My favorite is to assemble the pie the day before and bake it the morning of my party but any of these methods will work well:
1. Assemble the Day Before
Follow the recipe right up through to just before baking. Keep the fully assembled, unbaked pie in your fridge for up to 24 hours. Then preheat the oven and bake as directed.
2. Just Prep the Pie Crust Dough
You could prepare the dough for the pie crust and keep it chilled in the fridge for easy rolling and baking the next day.
The pie dough also freezes well by itself, just thaw in the fridge overnight before you try to roll it out.
3. Assemble and Freeze the Pie
You could fully assemble the apple slab pie and then flash freeze it for one hour. Then wrap it tightly in aluminum foil and freeze for up to 12 months.
When you want to bake the pie, you can bake it directly from the freezer. Just unwrap it from the foil but keep it loosely covered for the first 20 minutes of baking so the top crust doesn't brown too quickly.
You will need to add additional time to the baking time to ensure the pie filling gets hot and bubbly.
4. Bake It the Day Before
You could assemble and bake the entire pie recipe the day before your party and keep it at room temperature.
The pie will reheat well in the oven at 350°F if you want to serve it warm with a scoop of vanilla ice cream.
