Ingredients

Scale

Pie Dough

  • 3 ¾ cups (470 grams) all-purpose flour
  • 1 ½ tbsp sugar
  • 1 ½ tsp table salt
  • 3 sticks (12 oz or 340 grams) unsalted butter, cubed and kept very cold
  • ¾ cup very cold water

Filling

  • 3 ½ to 4 pounds apples, peeled, cored and chopped into approximately ½-inch chunks (about 10 cups)
  • Squeeze of lemon juice
  • to ¾ cup sugar (depending on sweetness preference and apple sweetness)
  • 3 tbsp cornstarch
  • 1 rounded tsp ground cinnamon
  • ¼ tsp ground nutmeg
  • ¼ tsp ground allspice
  • ⅛ tsp table salt

Finishing

  • 2 tbsp heavy cream or 1 egg beaten with 1 tbsp water (for brushing)

Instructions

  1. Make the crust: Measure the flour into a large, wide bowl. Whisk in the sugar and salt. Toss in the cold butter cubes and coat them with flour. Using your fingers, two knives, or a pastry blender, break the butter into small pea-sized pieces until the mixture is uniform and crumbly.
  2. Add water and form dough: Stir in ½ cup water using a rubber spatula until absorbed and dough starts coming together. If still crumbly, add remaining water tablespoon by tablespoon until the dough forms a soft, loose ball. Divide dough into two pieces, one larger for bottom crust. Shape each into a rectangular block about 1-inch thick, wrap in plastic, and chill for at least 2 hours.
  3. Prepare the filling: Toss apple chunks with lemon juice in a large bowl. In a medium bowl, mix sugar, cornstarch, cinnamon, nutmeg, allspice, and salt. Sprinkle over apples and toss to coat evenly. Set aside.
  4. Preheat oven and prepare pan: Preheat oven to 375°F (190°C). Line a 10×15×1-inch baking sheet or jelly roll pan with parchment paper.
  5. Roll out bottom crust: On a floured surface, roll out larger dough piece into an 18×13-inch rectangle. Transfer to the pan and gently press into pan corners, draping edges over sides. Chill in fridge or freezer while rolling out top crust.
  6. Roll out top crust and assemble: Roll out smaller dough piece to a 16×11-inch rectangle. Remove pan with bottom crust and pour apple filling evenly over it. Drape top dough over apples, trim excess leaving about ¾-inch overhang, and seal edges tightly by pressing with fingers.
  7. Prepare for baking: Brush the top crust with heavy cream or egg wash. Use a sharp knife to cut multiple 1-inch slits on top to vent steam. Place the pan on a larger baking sheet to catch spills.
  8. Bake the pie: Bake for 40 to 45 minutes until the crust is golden brown and the filling bubbles through the vents. Remove from oven and cool on a wire rack for at least 45 minutes before slicing and serving.

Notes

  • Make sure the butter and water are very cold to ensure a flaky crust.
  • You can adjust sugar according to the sweetness of your apples.
  • Resting the pie after baking helps the filling set, making it easier to cut clean slices.
  • Using a larger baking sheet underneath helps catch any spills and keeps your oven clean.
  • This pie keeps well for up to 3 days refrigerated and can be reheated gently before serving.
