This Easy Apple Slab Pie takes 10 mins thanks to store-bought puff pastry and a warm apple and cinnamon mixture. Homemade apple pie in minutes without the fuss.
Ain’t nobody got time to make a from-scratch apple pie
Not with kids that are wrestling each other on top of couches or a never-ending pile of laundry we’ve thrown on the guest bed in the basement. But that doesn’t mean I also want to go out and buy all my baked goods from a store and deal with all of the junk that comes in those baked goods.
Say hello to the Easiest Apple Slab Pie ever. It just so happens to taste just as good as a real apple pie — and maybe even better because you only took 10 minutes of your time to assemble it. The taste of sweet, sweet efficiency.
What’s a slab pie anyway?
A slab pie is just a shallow pie that’s usually made in a rectangular baking sheet or pan instead of a pie dish. This one doesn’t even require a rectangular pan or for you to make your own dough. Buy frozen puff pastry from the grocery store and put that on a parchment-lined baking sheet. You’ve “made” your crust, and it comes perfectly buttery and flaky without any labor.
This apple slab pie’s nearly identical twin (you know the Irish twin-type) is the galette, except the contents of this pie (apples, cinnamon, and sugar) are actually contained by crust on all sides, as opposed to the galette whose crust gets folded on top of the contents, leaving the fruit to peak out from the top.
What apples should I use?
Unlike this homemade applesauce or my healthy apple cinnamon muffins where I recommend a blend of super tart varieties and super sweet apple varieties, for this apple pie I recommend you go with super tart baking apples — like Granny Smith. Washington Apples has a cool apple profile if you’re interested in learning more about which varieties are tart and which are sweet. With that being said, in a pinch I use whatever apples I have around, and it still comes out delicious.
To peel or not to peel?
This is a total toss up, depending on my mood. Sometimes I use a vegetable peeler and quickly peel from the top of the stem to the bottom of the apple. This, of course, sometimes leaves a little bit of skin on the bottom and top of the apple. When I slice the apple in 4 segments around the core, I’ll either cut off the leftover peel or just leave it.
The other half of the time I don’t even go through the trouble of peeling my apples. I don’t mind the peel on cooked apples in the least, so skip this step entirely if it doesn’t bother you either.
Working with puff pastry
If you’ve never worked with puff pastry, it’s super simple. You can find it in the frozen foods aisle at any grocery store, in a variety of different brands. In my experience, the more money you pay for your puff pastry, the much better quality it is. I wouldn’t say the cheaper brands are bad, but you can definitely tell the more expensive ones (like Dufour) are much more buttery and flaky.
You do not need to defrost your puff pastry overnight. Just take it out the freezer about 30 minutes before you are ready to use it for this recipe. It will defrost enough for you to safely unfold without tearing the pastry.
Making the filling for the puff pastry apple pie
In a large non-stick pan, melt your butter over medium heat. Then add your apples, cinnamon, brown sugar until apples get nice and tender. Your kitchen will smell incredible already.
While your apples are cooking, lay our your defrosted puff pastry onto a parchment-lined sheet pan or cookie sheet. Once the apples are tender, you’ll pour the contents from the pan onto one of the sheets of puff pastry, including the ooey gooey, buttery sauce. Be sure to leave about an inch perimeter all around the puff pastry sheet so you can properly close your apple pie (see next step). It’s okay if some of the juices escape. Messy pies are still delicious pies.
Then simply place the other sheet over the apples, and use your fingers to pinch the puff pastry sheets together.
Brush your egg wash over the entire top of the apple pie, and then cut an “X” in the middle of the pie so some heat can escape. Stick in the oven for approximately 20 minutes or until the pie is golden brown.
BAM! You’re done and it took hardly any effort to have the most delicious, flaky apple pie crust around.
