What is Apple Slab Pie? Well, it’s apple pie in bar form that makes this dessert great for large groups & potlucks! You get way more servings than the traditional pie dish & it’s got this great glaze over the top! The crust is so flaky!
This recipe also has a little secret…the secret to no runny filling. Want to know what it is? Panko breadcrumbs! You spread a layer over the bottom crust & then put your filling in & it absorbs any liquid, so when you cut & serve these apple pie squares, there is no soggy crust or drippy filling! Win-win!
Apple Slab Pie
- 1 1/2 cups butter flavored Crisco shortening
- 3 cups all-purpose flour
- 1 whole egg
- 5 Tbsp cold ice water
- 1 Tbsp white vinegar
- 1 tsp salt
- 8 cups Granny Smith apples (peeled, cored, & sliced (about 6-8 apples depending on size))
- 6 Tbsp sugar, increase sugar depending on how tart your apples are
- 1 Tbsp cinnamon
- 1/4 tsp nutmeg
- 2 Tbsp cornstarch
- 1 cup Panko breadcrumbs (or other coarse dry bread crumbs; or 1 cup coarsely crushed cornflakes)
- 1 1/2 cups powdered sugar
- 1/4 cup apple cider
- small pinch of salt
- 1/2 tsp cinnamon
- 1 tsp milk or cream, optional, if necessary to thin the glaze (*substitute 1/3 cup honey OR 1/4 cup thawed frozen apple juice concentrate or maple syrup)
- To make crust: In a large bowl, with a pastry cutter gradually work the Crisco into the flour until it resembles a coarse meal. In a small bowl, beat an egg with a fork & pour it into the flour/shortening mixture. Add cold ice water, white vinegar, & salt. Stir together until all ingredients are incorporated. (I had to add extra flour b/c it was very wet; if you need to add flour do ¼ cup at a time, until it comes together.)
- Separate dough into 2 pieces 60% by 40%. You need one slightly bigger than the other. Shape into rectangles & wrap in plastic wrap. Place in freezer for 15-20 minutes.
- Meanwhile prepare the filling by peeling, coring, & slicing apples. After apples are ready, sprinkle sugar, cinnamon, nutmeg, & cornstarch. Toss to coat. Let macerate at room temperature while you clean up.
- Preheat the oven to 350*F. Pull the larger piece of pie dough out of the freezer. Roll into a 11x15" rectangle. Place the crust in an un-greased 9x13" pan. Patch up any holes by pushing the pastry together with your fingers. Push the pastry up the sides of the pan a bit, to make a shallow pastry container for the apples.
- Spread bread crumbs or crushed cornflakes evenly over the crust. Spread the sliced apples atop the crumbs.
- Remove the smaller crust from the freezer. Roll into a 9x13" rectangle. Lay the top crust over the apples. Seal the edges of the two crusts as well as you can.
- Bake for one hour until crust is golden brown, & filling bubbles. Remove from oven & allow to cool completely before glazing.
- To make the glaze: Combine the powdered sugar, apple cider, cinnamon, salt & enough milk or cream to make the mixture pourable, but thick. Add milk/cream a little at a time b/c it is easier to add more than to try to take it away. Drizzle the glaze over the apple slab pie.

Would you happen to know if you could make this with blueberries? If so how much Blueberries would I use? Fresh? or Frozen? Thank you for your advice. I just found your site and Love it!
For sure! I would do:
4-5 cups frozen blueberries (around 24oz if you buy frozen)
1/2 cup sugar
6 Tbsp cornstarch
Combine the sugar & cornstarch & toss the berries in it. Make sure you do the layer of panko (but maybe only 1/2 cup) on the bottom as well. The cook time should remain the same (60 min/1 hour.)
That’s 4 to 5 cups, it kind of looks like 45 which would be way too much!
Thanks so much for your reply! I appreciate you giving me all the “other things” I would need to make it blueberry too! I am making this for a group outing this Friday! I can’t wait!
I wonder if maybe I didn’t slice my apples thinly enough. It seems that there was no “runny filling” for the panko to soak up. Basically, it’s like there is just a layer of panko crumbs under my apples, it’s not “compressed looking” like yours. Hmmmm…I also used braeburn apples, because I needed to get them used up. I topped mine with a homemade caramel drizzle, and it still tastes great, though!! Just baffling about the filling…thanks for the recipe, saw it on Pinterest!!
Did you give them the chance to macerate & release their juices? That’s the only thing I can think of; that or your apples were too old. Try letting them sit a little longer next time & get really wet. Glad it still turned out somewhat okay. 🙂
This looks great! Would love for you to join us on Foodie Friends Friday with a recipe! I’m your newest follower here!
Hey, this looks wonderful. I’ll make for our big Thanksgiving weekend. Can’t wait to try it. Panko is a great idea.
