Ingredients

For the Crust:

• 3¾ cups (470 grams) all-purpose flour
• 1½ tablespoons sugar
• 1½ teaspoons salt
• 3 sticks (12 oz or 340 grams) unsalted butter, cubed and cold
• ¾ cup cold water

For the Apple Filling:

• 3½ to 4 pounds apples (peeled, cored, and cut into ½-inch pieces, approximately 10 cups)
• Juice of 1 lemon
• ⅔ to ¾ cup sugar (adjust to apple sweetness)
• 3 tablespoons cornstarch
• 1 rounded teaspoon ground cinnamon
• ¼ teaspoon ground nutmeg
• ¼ teaspoon ground allspice
• ⅛ teaspoon salt

To Finish:

• 2 tablespoons heavy cream OR
• 1 egg combined with 1 tablespoon water (for brushing)

Step-by-Step Instructions

Step 1: Prepare the Crust

1. In a large bowl, whisk together the flour, sugar, and salt.
2. Add the cold butter cubes and toss to coat them in the flour mixture. Use a pastry blender or two knives to cut the butter into the flour until the mixture resembles pea-sized crumbs.
3. Gradually add the cold water, stirring gently until the dough comes together. Do not overmix.
4. Divide the dough into two portions, making one slightly larger than the other. Shape each portion into a 1-inch-thick rectangle, wrap tightly in plastic wrap, and refrigerate for at least 2 hours.

Step 2: Prepare the Filling

1. In a large bowl, toss the apple pieces with lemon juice to prevent browning.
2. In a separate bowl, mix the sugar, cornstarch, cinnamon, nutmeg, allspice, and salt. Sprinkle this mixture over the apples and stir until evenly coated.

Step 3: Assemble the Pie

1. Preheat your oven to 375°F (190°C). Line a 10×15×1-inch baking sheet with parchment paper.
2. On a lightly floured surface, roll out the larger portion of dough into an 18×13-inch rectangle. Gently transfer it to the baking sheet, letting the edges drape over the sides. Refrigerate the pan while rolling out the second dough portion into a 16×11-inch rectangle.
3. Spread the apple filling evenly over the bottom crust, including the juices. Cover the filling with the second dough rectangle. Trim any excess dough and seal the edges by crimping or pressing with a fork.
4. Brush the top crust with heavy cream or the egg-water mixture. Cut several 1-inch slits in the top to allow steam to escape.

Step 4: Bake the Pie

1. Bake for 40-45 minutes, or until the crust is golden brown and the filling is bubbling.
2. Remove the pie from the oven and cool on a wire rack for at least 45 minutes before slicing.

Kitchen Equipment Needed

Serving and Storage Tips

Serving Suggestions: Serve warm or at room temperature with a scoop of vanilla ice cream or a dollop of whipped cream for the ultimate treat.
Storage: Store leftovers tightly covered at room temperature for up to 2 days or refrigerate for up to 4 days.
Freezing: Wrap the cooled pie tightly in plastic wrap and aluminum foil. Freeze for up to 3 months. Thaw in the refrigerator before reheating in the oven.

Recipe Variations

• Caramel Apple Slab Pie: Drizzle caramel sauce over the filling before adding the top crust.
• Mixed Fruit: Combine apples with pears or cranberries for a unique flavor.
• Spiced Topping: Sprinkle a mixture of sugar and cinnamon over the top crust before baking for added sweetness.

Helpful Notes

• Choose the Right Apples: Use firm, tart apples like Granny Smith or Honeycrisp for the best flavor and texture.
• Cold Butter is Key: Keeping the butter cold ensures a flaky crust. Chill the dough and tools for best results.
• Don’t Skip the Slits: Cutting slits in the top crust allows steam to escape, preventing a soggy pie.
