There are just a few simple ingredients needed to pull this recipe together. They include:

How to make Apple Slab Pie with Crumble Topping

The first step is to prepare the apples. I’ve chosen a combination of Gala (or Fuji) and Granny Smith for this recipe. Peel, corn and dice into chunks.

To the bowl of apple chunks add flour, sugar, apple pie spice and lemon juice (if your apples are beginning to oxidize). This is optional, but also adds a nice bit of extra tartness to your pie.

To make 1 TEASPOON of your own apple pie spice, you’ll need:

Please note: the recipe card is for a HALF sheet pan, so you’ll need to double the pie spice for a total of two teaspoons.

Toss this all together and set aside.

Next, add flour, sugar, quick cooking or old fashioned oats and cold butter to a bowl and mash with a fork or pastry blender until crumbly.

On a lightly floured surface, roll until an even thickness. They generally come round, so you’ll need more than one. Press the pie dough into a sheet pan. I am using 2 sheets for a quarter sheet pan which is what is called for in a HALF sheet pan. I would personally buy two boxes for a half sheet pan and use 3 of them. Or, make your own dough 🙂 Press where the edges overlap and crimp the edges, trimming where necessary.

Place the apples into the crust and top with the crumble. Bake at 425 degrees until golden and the apples are tender. This took about 25-30 minutes for me.

I took the scraps and a fall leaf plunger cutter (available here) to separately bake the leaves with a bit of sanding sugar. These are completely optional. They puff up a bit and look really cute on top of the baked slab pie.

Allow to cool slightly and serve with your favorite vanilla ice cream on top. SO good!

Tender flaky crust, sweet and juicy apples, that crumble topping served with vanilla ice cream? It’s so delicious.
