Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the Crust:

2 ½ cups all-purpose flour
1 tsp salt
1 cup unsalted butter, cold and cubed
6 tbsp ice water
1 egg (for egg wash)

For the Apple Filling:

6 large apples (Granny Smith or Honeycrisp), peeled and sliced
¾ cup granulated sugar
¼ cup brown sugar
1 tbsp lemon juice
1 ½ tsp cinnamon
¼ tsp nutmeg
¼ cup cornstarch
2 tbsp butter, melted

For the Glaze:

½ cup powdered sugar
1 tbsp milk
½ tsp vanilla extract

Directions

Prepare the Crust

In a large bowl, whisk together the flour and salt.
Cut in the cold, cubed butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs.
Gradually add ice water, mixing until the dough comes together. Do not overwork the dough.
Divide into two discs, wrap in plastic wrap, and refrigerate for at least 30 minutes.

Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking sheet.

Make the Apple Filling

In a large bowl, toss the sliced apples with granulated sugar, brown sugar, lemon juice, cinnamon, nutmeg, and cornstarch. Let sit for 10 minutes to allow the flavors to meld.

Assemble the Pie

Roll out one dough disc on a lightly floured surface to fit the bottom of the baking sheet.
Transfer the rolled dough to the prepared baking sheet, pressing gently into the edges.
Spread the apple mixture evenly over the dough and drizzle with melted butter.
Roll out the second dough disc and cut into strips for a lattice pattern, or place it fully over the apples and crimp the edges to seal.
Brush the top crust with the beaten egg for a golden finish.

Bake the Pie

Bake for 40-45 minutes, or until the crust is golden brown and the filling is bubbling.

Add the Glaze

In a small bowl, whisk together the powdered sugar, milk, and vanilla extract.
Drizzle the glaze over the pie while it is still slightly warm.

Serve & Enjoy

Allow the pie to cool before slicing into squares. Serve warm or at room temperature.

FAQs

What type of apples work best for this recipe?

Granny Smith apples provide a tart contrast to the sweetness, while Honeycrisp offers a perfect balance of sweetness and crisp texture. You can also use a mix of both.

Can I use puff pastry instead of pie crust?

Yes, puff pastry can be used for a flakier texture. Adjust baking time as it may cook faster.

How do I prevent a soggy bottom crust?

Ensure the apples are not overly juicy by letting them sit for 10 minutes before assembling the pie. Also, preheating the baking sheet can help create a crisp bottom crust.

Can I make this pie ahead of time?

Yes, you can prepare the pie one day ahead and store it in the refrigerator before baking. Alternatively, bake it fully and store it for later.

Should I peel the apples?

Peeling the apples ensures a smoother texture, but you can leave the skins on for a more rustic feel.

How do I get a perfectly flaky crust?

Use cold butter, avoid overmixing, and chill the dough before rolling it out.

Can I use a different glaze?

Yes, a maple glaze or caramel drizzle can be used instead of the vanilla glaze.

Do I have to do a lattice crust?

No, you can simply place the top crust over the apples and cut a few slits for ventilation.

Can I use a different size pan?

Yes, but the baking time may need to be adjusted. A smaller pan will create a thicker filling, while a larger pan will result in a thinner layer.

What can I serve with this pie?

This apple slab pie pairs well with vanilla ice cream, whipped cream, or a drizzle of caramel sauce.
