How to make an apple slab pie recipe from scratch?

1. Mix: To start, mix the flour, salt, and sugar in a medium bowl. Add the cold butter and use a pastry cutter or pastry blender to cut the butter into small pea-sized bits.
2. Add: Then, add the ice-cold water one tablespoon at a time to the flour mixture, stirring with a wooden spoon after each tablespoon so you do not add more than you need. Stop adding water when the dough forms large clumps. It typically takes about ¾ cup. 
3. Fold: Next, using floured hands and a floured surface, fold the dough over and over until the butter is completely worked in. It should be easy to come together but not sticky. 
4. Form: Following, roll the dough into a large ball, divide the dough in half, and use your hands to flatten each half into discs about one inch thick. Wrap the first disk in plastic wrap and after that wrap the second disk of dough and refrigerate for at least two hours or up to five days. 
5. Filling: While the pie dough chills, mix all the filling ingredients in a large bowl and set it aside. Preheat the oven to 375 degrees F. 
6. Roll: After it has chilled, take out one disc and roll it out on a floured work surface until it is about 18 inches by 13 inches. Be sure to turn it a quarter turn every few rolls. 
7. Fill: Then, lay the dough on a 10- by 15-inch size rectangular baking sheet, letting the excess hang over the sides of the pan and trimming it to about one inch. Spread the filling over the top of the bottom crust. 
8. Roll: Immediately, take the other dough disc out of the fridge and roll it out in the same way as the first. Place the top crust over the filling, letting the excess hang over the edges. 
9. Seal: Next, squeeze the edges together with your fingers and then use a fork to crimp them. Cut a few slits in the top of the crust and then brush it with your egg wash. Sprinkle with coarse sugar if desired. 
10. Bake: Finally, cook the pie for about 40 to 45 minutes until the crust is golden brown and the filling is bubbling. 
11. Cool: Last, take it out of the oven and let it cool on a wire rack for several hours. 
12. Serve: To serve, add a drizzle of glaze on the pie before cutting.

How to serve:

Your guests and family will love seeing this huge apple slab pie on the dessert table this holiday season. Or you can make it for a birthday or other celebration. We have a few good serving suggestions here for you to try. 

• Why not add some caramel sauce for a caramel apple slab pie? 
• Top with whipped cream instead of using the traditional vanilla ice cream. 
• Add crumb topping to make this more like Dutch apple pie. 
• Warm pie with ice cream is fantastic though. If you want to use ice cream, try our delicious recipe for no-churn cherry pie.
• Apple shavings and cinnamon sugar on top would also taste amazing. 
• For an even sweeter treat, slather some cream cheese frosting on top instead of the glaze. 
• Use leftovers to make an apple crumble topping or apple coffee cake.

Frequently asked questions

What are the best apples for apple pie? 

Although you can use any type of apple in this recipe, we recommend you use your favorite apples. Also, there are some that are better than others. You want apples that are not going to turn into applesauce when you bake them. Also, you want them to be sweet and tart but not too sweet and tart. 

Honey Crisp apples are one of the favorites because they are firm, sweet, and not too tart. Granny Smith apples are also a favorite choice. These are tarter than the others but great for combining with other apples or fruits like pears.

Another good choice is Gala apples because they are sweet but mellow and they stand up to baking. Pink Lady apples are crisp and tart with a sweetness that is refreshing and firm enough for baking. Golden Delicious has an amazing taste but they do get soft when you bake them. 

What is a galette pie?

Galette is not actually a pie per se although some call it a freeform pie. Rather, it is a pastry that is wrapped around fresh fruit. You do not need a pie pan for this one, just a flat surface like a baking sheet pan. The dough is a lot like pie pastry but with a bit of cornmeal. 

You can use just about any fruit or even vegetables for this pastry, but it is most often done with peaches, nectarines, plums, or apples tossed with sugar and flour. You can also add lemon zest, cinnamon, nutmeg, and other spices. 

To keep the bottom from being soggy, brush it with egg white or layer it with crushed cookies or cake. Then you just put it on a piece of parchment paper on a baking pan, pile the fruit into it, and fold the edges over with a large opening in the top to release the steam. 

Does a pie need a bottom?

Many people say that a pie has to have a double crust to be a pie. But what about all those other yummy pies like pecan, chocolate, and pumpkin? They are pies and do not have a top crust.

However, the main thing is that a pie should have a bottom crust. Although there are recipes for crustless pies, this seems like more of a pudding or cake.

Why is my crust chewy?

To make the perfect flaky crust, you have to use cool ingredients, especially butter. Warm butter gets absorbed by the flour instead of coating it, making a chewier and tougher, less flaky crust. Do not remove the butter from the fridge until you are ready to make the pie crust. 

What is raw sugar?

Raw sugar is slightly amber in color, is larger and coarser than regular sugar, and has a caramel flavor. Also called turbinado sugar, it is made of 99% sucrose and a little bit of molasses. Many bakers use it on top of pastries to give them a crunchy texture and sweet caramel flavor. 

How to store leftovers:

1. Store: First, let your pie cool, and then cover it tightly in an airtight container in the fridge for up to five days. 
2. Freeze: To freeze, wait until it is completely cool and wrap it in plastic wrap before putting it into a freezer bag. It can be frozen for up to three months. 
3. Thaw: Then, the night before serving, thaw your pie in the fridge overnight. 
4. Reheat: Although this apple slab pie is delicious cold, you can reheat it. If you want the crust to be crispy, use an air fryer or toaster oven. If not, you can use the microwave.
