Ingredients:

  • 6 cups (900g) fresh peaches, peeled and sliced
  • 1/2 cup (100g) granulated sugar
  • 2 tbsp (16g) cornstarch
  • 1 tbsp (15ml) lemon juice
  • 1 tsp (2g) ground cinnamon
  • 1/4 tsp (1.5g) salt
  • 1 cup (120g) all-purpose flour
  • 1 cup (90g) old-fashioned rolled oats
  • 1 cup (200g) packed light brown sugar
  • 1/2 tsp (2g) ground cinnamon
  • 1/4 tsp (1.5g) salt
  • 1/2 cup (113g) unsalted butter, cold and cubed

Instructions:

  1. Preheat oven to 375°F (190°C) and lightly grease a 9x9 inch baking dish with butter or non-stick spray.
  2. In a large bowl, combine the sliced peaches, granulated sugar, cornstarch, lemon juice, 1 tsp cinnamon, and 1/4 tsp salt.
  3. Gently fold the ingredients together until the peaches are evenly coated in the sugar-starch mixture.
  4. Pour the peach mixture into the baking dish and spread into an even layer.
  5. In a medium bowl, whisk together the flour, oats, brown sugar, 1/2 tsp cinnamon, and 1/4 tsp salt.
  6. Add the cold, cubed butter to the dry ingredients. Using fingers or a pastry cutter, work the butter in until the mixture looks like coarse wet sand with some pea-sized lumps of butter remaining.
  7. Sprinkle the crumble mixture evenly over the peaches without pressing it down.
  8. Bake for 45 minutes until the topping is golden brown and the filling is bubbling.
