Ingredients:

  • 6 large Granny Smith apples, peeled and sliced into 1/4 inch wedges (approx. 3 lbs)
  • 3/4 cup granulated sugar
  • 2 tbsp cornstarch
  • 1 tbsp ground cinnamon
  • 1/4 tsp ground nutmeg
  • 1/4 tsp salt
  • 2 tbsp unsalted butter, melted
  • 1 cup all-purpose flour
  • 1/2 cup packed light brown sugar
  • 1/2 cup cold unsalted butter, cubed
  • 1/2 tsp ground cinnamon
  • 1/4 tsp salt

Instructions:

  1. Preheat your oven to 375°F (190°C).
  2. In a large mixing bowl, toss the sliced apples with granulated sugar, cornstarch, cinnamon, nutmeg, and salt. Once coated, drizzle in the melted butter and stir until the apples look glossy.
  3. Pour the apple mixture directly into a room-temperature 10-inch cast iron skillet. Press the apples down firmly with a spatula to remove air gaps and ensure the fruit is spread evenly to the edges of the pan.
  4. In a separate bowl, combine flour, brown sugar, cinnamon, and salt. Using a pastry cutter or fingertips, work the cold cubed butter into the dry ingredients until the mixture resembles coarse crumbs roughly the size of peas.
  5. Sprinkle the crumb topping evenly over the apples, covering the entire surface.
  6. Slide the skillet into the center rack of the oven and bake for 45 minutes until the topping is golden brown and the filling is bubbling.
