Can I make Apple Slab Pie ahead of time?

Yes, Apple Slab Pie is an excellent make-ahead dessert. You can prepare the pie dough in advance and keep it refrigerated for several days before baking. The fully baked pie can also be made a day before serving, allowing the flavors to develop while saving time on busy occasions. For the best texture, store the finished pie covered at room temperature for a short period or refrigerate it if you need to keep it longer. Add the maple icing after the pie has cooled for the best appearance and flavor.

What are the best apples to use for Apple Slab Pie?

The best apples for Apple Slab Pie are firm varieties that hold their shape during baking. A combination of sweet and tart apples creates the most balanced flavor. Popular choices include Granny Smith for a tart contrast, Honeycrisp for sweetness and crunch, Pink Lady for a slightly tangy taste, and Fuji apples for natural sweetness. Mixing different apple varieties creates a more flavorful apple filling than using only one type.

How do I store leftover Apple Slab Pie?

Store leftover Apple Slab Pie in an airtight container or cover it tightly with plastic wrap. It can remain fresh at room temperature for a short time, but refrigeration is recommended for longer storage. When stored properly in the refrigerator, the pie can last several days. Individual slices can also be frozen and reheated gently in the oven when you are ready to enjoy them again. This makes it a convenient dessert to prepare ahead for future gatherings.

Instructions

Prepare the crust by mixing flour, salt, and sugar in a large bowl. Cut in the cold butter until the mixture resembles coarse crumbs with visible butter pieces.
Add ice water gradually and mix until the dough comes together. Divide into two portions, shape into discs, wrap, and refrigerate for at least 2 hours.
Prepare the apple filling by combining sliced apples, sugar, flour, lemon juice, vanilla extract, cinnamon, nutmeg, and cloves. Mix until the apples are evenly coated.
Preheat the oven and prepare a 10×15-inch jelly roll pan. Roll out one dough portion into a rectangle and fit it into the pan.
Spread the seasoned apple filling evenly over the bottom crust.
Roll out the second dough portion and place it over the apples. Seal the edges, crimp with a fork, and cut small vents in the top crust.
Brush the crust with beaten egg and sprinkle with coarse sugar if desired.
Bake until the crust is golden brown and the apple filling is bubbling, about 40-46 minutes.
Cool the pie completely before preparing the icing. Mix confectioners’ sugar, maple syrup, and milk until smooth, then drizzle over the pie before slicing.

Notes

Use a combination of sweet and tart apples such as Honeycrisp, Granny Smith, Pink Lady, or Fuji for the best flavor.
Keep the butter and dough cold to achieve a flaky pie crust.
Do not overmix the dough because it can make the crust tough.
Allow the pie to cool before adding maple icing so the glaze sets properly.
Store leftovers covered in the refrigerator for up to several days.
The baked pie can be frozen and thawed before serving.
