Ingredients:

  • 6 cups (900g) fresh peaches, peeled and sliced
  • 1/2 cup (100g) granulated sugar
  • 1 tbsp (8g) cornstarch
  • 1 tsp (2g) ground cinnamon
  • 1 tbsp (15ml) fresh lemon juice
  • 1/4 tsp (1.5g) salt
  • 1 cup (90g) old-fashioned rolled oats
  • 1 cup (120g) all-purpose flour
  • 1 cup (200g) packed light brown sugar
  • 1/2 cup (113g) cold unsalted butter, cubed
  • 1 tsp (2g) ground cinnamon
  • 1/4 tsp (1.5g) salt

Instructions:

  1. In a medium bowl, combine sliced peaches, granulated sugar, cornstarch, cinnamon, lemon juice, and salt.
  2. Let the peach mixture sit for 5–10 minutes to macerate and release natural juices.
  3. Pour the peach mixture into a 9-inch cast-iron skillet or baking dish, spreading them evenly.
  4. In a large bowl, whisk together the rolled oats, flour, brown sugar, cinnamon, and salt.
  5. Add the cold, cubed butter to the dry ingredients and work it in with a pastry cutter or forks until the mixture resembles coarse crumbs with pea-sized lumps.
  6. Sprinkle the crumble evenly over the peaches without pressing down.
  7. Bake in a preheated oven at 375°F (190°C) for 30–35 minutes until the topping is deep golden brown and the fruit juices are bubbling.
  8. Allow the crisp to cool for 10 minutes before serving to let the filling set.
