Apple Slab Pie is my favorite kind of pie: it’s baked in a sheet pan so there is more crust and crumble ratio to apples. This recipe is completely from scratch and I’ve done all the math for you to convert my favorite crumb apple pie to a larger slab pie!

Do you love pie? I do. Obviously. You know what I love even more? Slab apple pie! They’re like pie bars, but it makes more. More pie = win. Apple slab pie? Totally #pieforthewin.
I really, really love apple pie. In fact, it’s why I started this blog. I loved it so much that I re-did the photos because the others sucked. Then I made them into mini apple pies last Thanksgiving. And now I’m turning into an easy-to-serve SLAB pie that feeds a crowd. A slab pie is approximately double a regular pie in size and baked in a jelly roll (10×15-inch) pan or a 9×13-inch pan. It’s easier to serve and feeds a crowd!

Apple Slab Pie Ingredients
- Pie Crust – This is basically one and a half times my all butter pie crust recipe. You’ll need butter, salt, all-purpose flour, and ice water to make it.
- Apples – I use Granny Smith Apples for my pies because I like the combination of the tart apple with sweet crumble.
- Sugar – Granulated sugar for the apples and the crumble.
- Cinnamon – It wouldn’t be an apple pie without cinnamon!
- Salt – a pinch for the crust and topping.
- Flour – You’ll need all-purpose flour to make the crumble
- Oats – Also for the crumble topping. This is different than my all purpose crumble recipe, but I love the texture oats add (not pictured above).

Dorothy’s Testing Notes
- This pie is baked in a 10×15-inch Jelly Roll pan. (For those of you who have made one of my cake rolls, you already have this pan!) The pan also has 1-inch sides.
- I always cook my apples when I make pie. It is SO MUCH BETTER!
- Make sure you peel, core and slice your apples the same size (I use my handy dandy apple peeler and it takes all the time out of it).
- How to serve apple slab pie: Serve this with whipped cream or ice cream. I love serving it warm – reheat in a 200°F oven until warm, or heat slices in the microwave. It’s also great topped with caramel sauce!

Ingredients
Crust:
- 1 ¾ cups + 2 tablespoons (233g) all-purpose flour
- ¾ teaspoon salt
- 1 ½ cups (339g) unsalted butter, diced and cold
- 2-3 tablespoons (30-45ml) ice water
Filling:
- 3 pounds Granny Smith Apples
- ¼ cup (50g) granulated sugar
- ½ teaspoon ground cinnamon
Crumble
- ½ cup (113g) unsalted butter, softened
- ½ cup (100g) granulated sugar
- ¼ teaspoon salt
- 1 cup (124g) all-purpose flour
- ½ cup (44g) oats, (quick or old fashioned)
Instructions
- Make your crust: Pulse flour and salt in a food processor for a second. Add butter and pulse until butter has been worked through the flour. Add water, 1 tablespoon at a time, until the dough comes together (I used 2 1/2 tablespoons water).
- Carefully roll out dough on a lightly floured nonstick surface (like a silicone mat). Roll into a large rectangle. Spray a jelly roll pan (10×15”) with cooking spray. Press into the bottoms and up the sides of your pan. Chill until apples are ready, or cover with plastic wrap and chill for as long as overnight.
- Preheat oven to 350°F.
- Peel, core, and slice apples to a small dice. Place 1-2 inches of water in the bottom of a pot. Add apples and cook, stirring occasionally, approximately 3-5 minutes after water boils. You want the apples semi-opaque but not mushy.
- Mix 1/4 cup sugar and cinnamon in a small bowl and set aside.
- Using a hand mixer, mix crumble ingredients in a large bowl. You may need to use your hands or a pastry cutter to break up the large bits of butter.
- Once apples are cooked, drain them well. Spread apples evenly over the crust and then sprinkle the apples with the cinnamon sugar.
- Sprinkle the crumble over the top of the apples and press to compact.
- Bake for 40-50 minutes until topping begins to brown. Cool before cutting. Serve with ice cream or whipped cream.
- Store covered in the refrigerator for up to 4 days, or wrap slices with plastic and seal in a ziploc bag, and freeze for up to one month.

How to Make Apple Slab Pie
- For this recipe I made 1 1/2 times the amount of my all butter pie crust. That was perfect for this size pan.
- Semi-homemade option: You can also use two refrigerated Pillsbury pie crusts (one box). Bring them to room temperature, place one on top the other and roll them together until they’re the size that will fit the pan.
- You know your crumble is done when much of the mixture is in pea sized pieces.

- The apples shouldn’t be fully cooked through, just slightly opaque around the edges.
- The apples should be fully drained so as not to make a soggy pie.
- The crumble will be a nice even layer.
FAQs
If you want a glaze on top mix 1/2 cup powdered sugar with about 2-3 tablespoons heavy whipping cream. Whisk and then drizzle over the top of the cooled pie.
That depends on how you make your pie. If you are pre-cooking your apples like I do you can do cubes, chunks or slices. If you are not par-boiling your apples you should do thin slices so they cook through in the oven.





A whole pound of butter seems like a lot for one apple pie, regardless of it being a slab pie! The ratio of of 2 3/4 total cups of flour, including crumbs, to a pound of butter, including the crumbs, seems like an awful lot of butter! I love all your recipes, but this seems a little too much. But, you apparently tested this? Just curious.
I test and eat every single thing on this site. yes, it’s a lot of butter, but it makes a ton of servings.
Is this freezeable?
Yes
Hi!
This looks delicious!!! I just had a quick question for you. In the recipe description for the crust you said that it’s 1.5X the original amount. But maybe my math is wrong, the butter seems to be more in this Apple Slab Pie recipe.
apple pie
1 3/4 cups + 2 tablespoons all-purpose flour
3/4 teaspoon salt
1 1/2 cups unsalted butter diced and cold
2-3 tablespoons ice water
orig crust x 1.5
3/4 cup unsalted butter diced and chilled
1.875 cups all-purpose flour
3/4 teaspoon salt
3-6 tablespoons ice water
Any help would be appreciated! Thank you!!
Why do you cook the apples first?
I don’t like crunchy apples in pie, so I partially cook them. If you like crunchy apples you can toss them with cinnamon sugar and skip that step.
OMG that crumble topping is amazing. I love it!!
