Apple Slab Pie has warm, tender spiced apple filling that’s sandwiched between a layer of flaky crust and finished off with a coat of glaze! Cooks in just 35 minutes!
One of the best things about Fall is all of the Apple flavored desserts that start to come out of the oven! You can catch this pie along with Apple Cheesecake Bars and Apple Crisp coming out of my kitchen all season long!
Apple Slab Pie has the same great taste you get from a classic apple pie except it’s made and baked on a large sheet pan! I love making this for large gatherings since it’s a lot easier to cut this up into squares and serve it verse slicing up a traditional pie!
What I Love About This Recipe!
- Pie Dough! I used pre-made store-bought refrigerated pie crusts for this recipe but you can use your favorite homemade pie dough if you’d like!
- Easy Ingredients! Pair the pie dough and apples with ingredients that are likely tucked right inside your pantry!
- The Sweet Glaze! The Apple Slab Pie gets brushed with the sweet easy-to-make glaze multiple times to make it a nice, thick layer!
- Enough For Everyone! Most 9-inch pies yield only 6 slices but this slab pie delivers a dozen servings! Plenty for everyone to enjoy and maybe even have some leftover! Plus it’s WAY easier to slice and serve than a traditional Apple Pie – although we love that recipe too!
With only 15 minutes of hands-on prep, this Apple Slab Pie Recipe makes for an easy dessert to bring to all of your Fall gatherings! To whip one up you’ll need 4 pie crusts, granny smith apples, granulated sugar, cornstarch, lemon juice, ground cinnamon, ground nutmeg, and fine sea salt.
While the apple dessert is cooling you’ll heat and whisk together the homemade glaze! All that’s needed for this sweet topping is whole milk, unsalted butter, and powdered sugar.
Feel free to use your favorite baking apple for this recipe! I chose to use granny smith but Honeycrisp, Braeburn, and pink lady apples would all be delicious choices as well!

How To Make Apple Slab Pie
Unlike some Pie Recipes, this slab pie is simple to make! Let’s go over it together step-by-step!
- Place the pie crusts out to allow them to come to room temperature. Then put two pie crusts on top of each other and roll them out into a rectangle using a rolling pin.
- Place the rolled-out crust onto a jelly roll pan. Allow the excess crust to overlap the sides of the pan. Set it aside.
- Stir together the sliced apples, sugar, cornstarch, lemon juice, cinnamon, nutmeg, and salt in a large bowl. Then spoon the apples evenly onto the crust.
- Roll out the last two pie crusts into a rectangle and place them on top of the filling. Tuck the top crust under the bottom crust and crimp the edges together.
- Bake for 30 minutes, tenting it with foil after the first 15 minutes. Bake the Apple Slab Pie until it’s golden brown.
- Cool on a wire rack. While the dessert cools add milk to a saucepan and heat over medium-low heat, remove as soon there’s any bubbling.
- Whisk in the butter and let it cool to room temperature before adding in the powdered sugar.
- Brush the glaze all over the Apple Slab Pie. Wait 30 minutes and brush another layer on.
You will have glaze leftover, save it to serve as a drizzle over the pie if desired. Or, you can continue to glaze it every 30 minutes until you have used it all up.

Apple Slab Pie
- Preheat the oven to 425°F. Leave the pie crusts out to come to room temperature per the directions on the box. Place two of the pie crusts on top of each other on a lightly floured work surface. Using a rolling pin, roll it out to a rough rectangle that is 18×12 inches.
- Using a 10x15x1 jelly roll pan, place the crust in the pan, forming it in the pan with the excess crust overlapping the sides. Set aside.
- In a large bowl, add the sliced apples, sugar, cornstarch, lemon juice, cinnamon, nutmeg, and salt. Stir together until fully combined. Spoon the apples evenly onto the crust.
- Again, roll out the last two pie crusts into an 18×12-inch rectangle. Place the on top of the pan. Tuck the top crust under the bottom and crimp the edges. Slice slits in the top crust so air can escape while baking.
- Bake for 30 to 35 minutes, tenting with foil after the first 15 minutes. Bake until golden brown. If you think it needs more browning after 35 minutes, take the foil off and watch closely until your desired color is reached.
- Place on a wire rack to cool for 1 hour.

- After the pie has cooled for 1 hour, brush it all over with the glaze with a pastry brush. Wait 30 minutes, brush another layer of glaze on. Let cool 30 more minutes, slice and serve.
- There are 2 pie crusts in each refrigerated box, so you only need two boxes to get the 4 crusts needed for this recipe.
