Ingredients

• 3 ¾ cups (470 g) all-purpose flour
• 1 ½ tbsp sugar
• 1 ½ tsp salt
• 3 sticks (12 oz) unsalted butter, cold and cubed
• ¾ cup ice-cold water
• 3 ½–4 lbs apples (about 10 cups), peeled and chopped

• 1 tsp cinnamon
• ¼ tsp nutmeg
• ¼ tsp allspice
• ⅛ tsp salt
• 2 tbsp heavy cream or 1 egg beaten with 1 tbsp water (for brushing)

Step-by-Step Instructions

1. Make the dough Whisk flour, sugar, and salt in a large bowl. Cut in cold butter until pea-sized crumbs form. Add water gradually, mixing just until a dough forms. Divide in two, shape into rectangles, and chill for at least 2 hours.
2. Prepare the filling Toss chopped apples with lemon juice. Mix sugar, cornstarch, and spices, then coat the apples until evenly covered with the sweet spice mixture.
3. Assemble the slab pie Preheat the oven to 375°F. Roll one dough piece to an 18×13-inch rectangle and fit into a parchment-lined 10×15-inch pan. Chill while rolling the second piece into a 16×11-inch rectangle.
4. Fill and seal Pour apple filling into the crust, top with the second layer of dough, trim, and crimp to seal. Brush with cream or egg wash and cut several steam vents.
5. Bake & cool Bake for 40–45 minutes, until golden and bubbling. Cool for at least 45 minutes before slicing into neat squares. Serve warm or at room temperature.
