This apple slab pie is loaded with caramelized apples and wrapped in a flaky puff pastry crust. The filling tastes like an apple pie but it’s even easier. It’s so easy and quick to whip up and you don’t even have to struggle with making your own dough; a store-bought puff pastry will work just fine. You can use your favorite apples for this but there’s nothing quite like a caramelized, slightly tart granny smith.
I should say this though; if you’re serving more than 4 people, you ought to double the recipe and make 2. That’s easy since a package of puff pastry comes with two sheets! It will be devoured quickly.
I’m wishing there were leftovers, but there never are with this one!
Ingredients for Apple Slab Pie:
1 lb (2 large) granny smith apples, peeled, cored and cut into 1/3″ slices
4 Tbsp unsalted butter
1/4 cup brown sugar, lightly packed
1 tsp ground cinnamon
1 sheet (8 or 9 oz) frozen puff pastry, thawed (I used Pepperidge Farms)
All purpose flour for dusting
1 egg, lightly beaten for egg wash
Coarse sugar for sprinkling (I used raw sugar)
How to Make an Easy Apple slab pie:
Preheat Oven to 400˚F.
1. In a large skillet or a dutch oven, melt 4 Tbsp butter over medium heat. Add sliced apples and cook, stirring occasionally until lightly browned (6-8 min). Reduce heat to low and stir in 1/4 cup brown sugar and 1 tsp cinnamon. Continue to simmer, stirring occasionally until apples are soft and caramelized (5 min).
You’ll be really tempted to eat your filling at this point. Go on and at least have a taste!
2. Lightly dust a sheet of parchment paper with flour. Place your thawed puff pastry dough over it and roll it out slightly to flatten the top (9 1/2 x 10 1/2 inches). Cut puff pastry dough in half down the center to make two pieces (each 4 3/4 x 10 1/2 inches.
3. Arrange apples in a tight row lengthwise down the middle of one puff pastry sheet leaving a one inch border on all sides. Pour remaining syrup from the apples over the top of the apples. Brush your beaten egg around the edges of your pastry. Top with the second pastry sheet and press down on the edges to seal.
4. Cut 6 (1-inch wide) slits down the center of your pastry to create vents.
5. Brush the pastry with egg wash and sprinkle the top generously with coarse sugar. Bake at 400˚F for 15-17 min or until top is golden brown.

Simple and super delicious. The filling makes it and always get rave reviews when I make it. Making 2 today and another 2 on Friday. As Natasha mentions, there is never any leftover. A winner recipe!
That’s so great! It sounds like you have a new favorite!
Made two of them last night for guests. Both ladies asked me to forward the recipe! Thanks so much. It was easy and turned out just like the photos. A small scoop of ice cream went well with the apples.
That’s so great! I’m so happy you all enjoyed this recipe!
Super-easy to follow! I had already made my own filling very similar to that in the recipe. Followed step to make it into a pie and voila! 15min later a have the most amazing fluffy pie! I had 3 slices on my own (goodbye, diet!)
That is so great to hear! Thanks for sharing that with us and I hope you will enjoy my other recipes too.
I followed the directions exactly but for some reason when I put the apples onto the puff pastry, the butter seperated from the brown sugar/cinnamon. It’s still in the oven. Hope it comes out as good as it looks. Not sure why it seperated though.
I hope you love this recipe Shannon!
With 2 lbs of apples I had enough to make 3 slab pies, with still a bit leftover!? I didn’t ‘lay out’ the apples like you did, I just put them helter skelter.
Totally delicious and fun to see something different.
Thank you. Love your recipes.
I’m so happy you enjoyed that Libby! Thank you for this wonderful review!
I’ve made this before…delicious! It’s very easy to whip together. I have a bunch of apples we picked and was wondering if I could make this dessert and freeze it? If so would you suggest freezing it before or after cooking?
Hi Karen, to be honest, I haven’t tried freezing the whole pie so I can’t really say for sure. It’s a good idea and if you try it, let me know how it works out
i wouldn’t thaw the puff pastry and then re-freeze it. I would try freezing after you bake it but leave off a few minutes so when you reheat it, it will be perfect. Then sprinkle the sugar on top.
very nice recipe however the prep took me about an hour from the time i started peeling the apples lol
turned out very lovely thanks
You’re welcome! I’m so happy you enjoyed that Evelyn!
Made a double recipe with apples from Misfits… Used 2 of the Lakeside Collection 4-Pc. Layer Cake Pans Set
Which gave me a sunken area to hold the filling. My husband thought it was reminiscent of apple strudel
I’m so happy you enjoyed that. Thank you for sharing that with us!
Had puff pastry in the freezer and apples in the fridge. My 14 year old son was bored and whipped up your recipe. Turned out PERFECT! Best part is that he had fun making it.
Great to hear that, Kristen! Good job to your son too.
Just made these. Delicious,! Just added some nuts and raisins. First time trying a recipe by Natasha. Looking forward to trying others.
I’m so happy you enjoyed that. Thank you for sharing that with us Luciella!
I’m 13 and made this with b=my brothers. Its really good and was so easy. Thanks for the amazing recipe!💙
I am so glad you enjoyed the pie. Thanks for your great review!
Perfect way to make a quick dessert with no stuff you have at home. Tasted amazing.
I split the slab in half (so made 2 pies) same time and temp and worked perfectly👍🏽
I am so glad you loved this recipe. Thanks for your great feedback!
hi,,are those measurement suitable for 2 people? because it is for my schoolwork :’ thank youu
Hi Ain, this makes 4 servings.
do you have recipe for pastry puff for 2 serving?
Hello Ain, I don’t have a recipe for pastry puff yet but that’s a good suggestion.
My 11 year old tried the Apple cinnamon slab pie today. The recipe was very easy to follow and it came out very well. Thank you Natasha.
Great job to your little baker!
This is always a winner, I love making this for when the family comes over. Goes fantastic with a simple vanilla ice cream.
I’m so glad you enjoyed it! Thank you for the wonderful review!
Can I make individual mini “pies instead of 1 big one and bake it at the same temperature? And has anyone tried cinnamon/ brown sugar on top instead of regular coarse sugar?
Hi Liz, I haven’t tested that but one of our readers had with great results. If you experiment, let me know how you liked the recipe
Do you che to roll out pastry or can you use it thawed as is?
For the best results, I would follow the instructions listed.
Amazing! I added a little cornstarch to thicken the sauce but this was delicious!
Love it! Thanks for sharing and for your great feedback, Jasmine.
Turned out really well
This was a great comfort food during quarantine. I had less flavorful apples so I added 1/2 tsp of ginger and some lemon zest and it tasted terrific!
That’s so great! I’m glad you enjoyed that Susan!
I did double the recipe and found there was too much butter. Will double everything else from now on and keep butter amount the same. Can hardly wait to eat it!
Thank you for sharing that with us, Pattio. I’m so glad you enjoyed this recipe.
This recipe is so easy to follow and so delicious with a scoop of vanilla ice-cream to pair! I didn’t have unsalted butter so just used salted butter instead but still turned out perfect! Thank u for this wonderful recipe!
That is so awesome, Lisa. Thank you for sharing that with us and for your great feedback!
