Ingredients:

  • 1.25 cups (160g) all-purpose flour
  • 0.5 cup (115g) unsalted butter, chilled and cubed
  • 1 tablespoon (12g) granulated sugar
  • 0.5 teaspoon (3g) salt
  • 4 tablespoons (60ml) ice-cold water
  • 2 (6 oz / 170g each) Granny Smith apples, peeled and sliced
  • 2 (6 oz / 170g each) Honeycrisp or Macintosh apples, peeled and sliced
  • 3 tablespoons (36g) melted unsalted butter
  • 0.25 cup (50g) light brown sugar, packed
  • 1 teaspoon (2g) ground cinnamon
  • 1 tablespoon (16g) cornstarch
  • 1 tablespoon (15ml) lemon juice
  • 1 large egg, beaten
  • 1 tablespoon (8g) coarse sanding sugar

Instructions:

  1. In a large bowl, whisk together the all-purpose flour, granulated sugar, and salt.
  2. Add chilled butter cubes and use a pastry cutter or fork to work the butter into the flour until the mixture resembles coarse crumbs with pea-sized chunks.
  3. Stir in ice water one tablespoon at a time until the dough just begins to clump together.
  4. Form the dough into a flat disk, wrap in plastic, and refrigerate for 30 minutes.
  5. Toss sliced Granny Smith and Honeycrisp apples in a bowl with lemon juice.
  6. Add melted butter, brown sugar, cinnamon, and cornstarch to the apples; toss until evenly coated.
  7. On parchment paper, roll the chilled dough into a rough 12-inch circle.
  8. Pile the apple mixture into the center of the dough, leaving a 2-inch border.
  9. Gently fold the edges of the dough up and over the apples, pleating the crust while leaving the center open.
  10. Brush the folded crust with beaten egg wash and sprinkle with coarse sanding sugar.
  11. Slide the parchment onto a baking sheet and bake at 400°F (200°C) for 30–35 minutes until the crust is mahogany and apples are bubbling.
  12. Let the galette rest for 10 minutes before slicing.
