Ingredients:

  • 1 1/4 cups (160g) all-purpose flour, plus more for dusting
  • 1/2 teaspoon (3g) granulated sugar
  • 1/4 teaspoon (1.5g) salt
  • 1/2 cup (113g) unsalted butter, very cold, cut into 1/2-inch cubes
  • 4-6 tablespoons (60-90ml) ice water
  • 4 medium apples (such as Honeycrisp, Granny Smith, or Gala), peeled, cored, and thinly sliced (about 4 cups)
  • 2 tablespoons (25g) unsalted butter, melted
  • 1/4 cup (50g) granulated sugar
  • 1 tablespoon (7.5g) all-purpose flour
  • 1 teaspoon (2g) ground cinnamon
  • 1/4 teaspoon (0.5g) ground nutmeg
  • 1 tablespoon (15ml) lemon juice
  • 1 large egg, beaten (optional)
  • 1 tablespoon (15ml) milk (optional)
  • Turbinado sugar or coarse sugar (optional)

Instructions:

  1. Combine flour, sugar, and salt in a large bowl. Cut in cold butter until the mixture resembles coarse crumbs. Gradually add ice water, mixing until the dough just comes together. Form into a disc, wrap in plastic wrap, and chill for at least 30 minutes.
  2. In a large bowl, toss apple slices with melted butter, sugar, flour, cinnamon, nutmeg, and lemon juice.
  3. On a lightly floured surface, roll out the chilled dough into a 12-inch circle (it doesn't have to be perfect!). Transfer the dough to a parchment-lined baking sheet.
  4. Arrange the apple slices in the center of the dough, leaving a 2-inch border.
  5. Gently fold the edges of the dough over the apple filling, pleating as needed.
  6. Brush the crust with the egg wash (if using) and sprinkle with turbinado sugar or coarse sugar.
  7. Bake in a preheated oven at 375°F (190°C) for 35-40 minutes, or until the crust is golden brown and the apples are tender.
  8. Let the galette cool slightly on the baking sheet before slicing and serving.
