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.

OMG what a fantastic recipe I made this tonight and it was gone in seconds. Thank you for a brilliant recipe with well laid out easy to follow instructions, and best of all my one looked just like yours which for a non baker is no mean feat !!
I’m so happy you loved it! That just makes my day. Thanks Pauline 🙂
Natasha, I made this for Thanksgiving yesterday and my daughter (she’s 10) took a bite and look at me and said “mommy, this is the best pie you’ve ever made”!!!! I think I just started a family tradition! Thank you for being part of it!
Aww that is the sweetest thing! Thank you so much for sharing that with me 🙂
you say to brush braided pastry with egg but no where are there directions showing braid. looks delish, by the way!
Good catch Caroine, it was a typo, I will fix that right away :).
Yummy! Love for easy this was to make for my family
I’m so happy you liked it 🙂
This looks so good! I still have a ton of Apple’s to use up even after making applesauce and some cookies. Do you think the filling could be made ahead and frozen? I wasn’t sure since the Apple’s are cooked…
I think that would work fine; I don’t see why not! 🙂
Hi there. I saw this on Pinterest and made it tonight and wanted to share –this one works! No fail, and I tend to fail on desserts. It was so easy to make and turned out delicious. I cut back on the butter and sugar and it still turned out stellar. Thanks for sharing.
I’m so happy you enjoyed it and thank you very much for such a wonderful review! 🙂
How do these hold up the next day? Thinking of making for a party, but not sure how they will taste (if they will become mushy?)
They stay flaky. You can even keep them at room temp overnight. 🙂
Any advice on trying to do this with defrosted vishnya (sour cherry)?
Thanks!
You wouldn’t have to pre-cook them, just drain them enough so they aren’t oozing down the borders when you put them on and sprinkle the top of the cherries generously with sugar. You might sprinkle sugar on the area of the dough you are going to put the cherries. I think this would be delicious with cherries.
Made two batches of this yesterday and absolutely love it. I used puff pastry dough from Trader Joes and Jona Gold apples.
I haven’t tried Trader Joes puff pastry but now I really want to. I didn’t even realize they had it there! 🙂 Thanks for the tip!
Sadly TJ’s puff pastry and phyllo dough’s quality is quickly going down the drain. Puff pastry has less layers so it doesn’t puff well or high enough- stick with the brand in your pics. Their phyllo dough is no longer elastic and is very brittle- I get mine from the greek groceries.
Oh that is a bummer :(. It’s such a bummer when companies cut corners and it affects their product and then customers notice! Yikes! Good to know that one doesn’t work. Thank you for sharing 🙂
Gahhh! This slab pie looks so much better than a regular pie…although that makes zero sense so I don’t know why! Probably because you made it. Pinned
You’re funny Lindsey but I sure appreciate the compliment! 🙂 Thanks so much for pinning!
these are so yummy! i made little mini ones so their easier to eat. i never thought about caramelizing the apples, but it give it so much more flavor! love it!
Min ones sound really good too! Thanks for the idea! 🙂
I just made this and its so yummy!!!! I made two right the way 🙂
Could just eat it myself 😀
Thanks for sharing ur recipe 🙂
You’re smart; making two right away! 🙂 Now if I could just convince you to send one of them my way! 😉
Absolutely gorgeous, love that sugared topping!
Thanks Laura 🙂 I couldn’t help it 😉
I love using puff pastry for easy and quick baking. We picked apples last weekend so this would be perfect!
Me too! I love to keep some puff pastry in the freezer for these kinds of cravings 🙂
This is such an easy way to satisfy a pie craving!
It sure is! Except I wished I had made two. It disappeared way too quickly! 🙂
Another nice recipe. Thanks so much.
You’re so welcome Liz 🙂
Such a simple and delicious recipe! I just made the same thing in the turnover shape last week! Love the apple season!
I’m excited to try this same thing with plumbs and persimmon. Except the plums might be even easier since they probably don’t need any pre-cooking. Can’t wait! 🙂
This is also called a strudel 🙂 traditionally it’s rolled in flakier pastry, but I love it in puff pastry, and it’s much faster! My granny learned how to make this from her neighbor, who was a German woman who actually lived in Odessa, and came to America from Ukraine after WWII. I’m curious to try it though with cooking the apples a bit first before putting it in the puff pastry, it looks tasty! 🙂
With the apples, I felt it was a necessary step since they only bake for about 15 minutes; it’s not really enough to soften or caramelize them. Other fruits like plums might not need pre-cooking.
This looks so good and simple to make… The best thing is that I already have all the ingredients.!!!!! : )
I love it when that happens! Enjoy it 🙂
Oh yes! I have tons of apples around. This looks amazing, Natasha!
I hope you love it! My husbands only complaint was that I didn’t make more 😉
