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 (90g) old-fashioned rolled oats
  • 1 cup (125g) all-purpose flour
  • 1 cup (200g) packed brown sugar
  • 1/2 tsp (1g) ground cinnamon
  • 1/2 cup (113g) unsalted butter, chilled and cubed

Instructions:

  1. In a large bowl, combine the sliced peaches, granulated sugar, cornstarch, lemon juice, cinnamon, and salt.
  2. Let the peach mixture sit for 5 minutes until a light syrup forms.
  3. Pour the peach mixture into a 9x9 inch baking dish, spreading evenly.
  4. In a medium bowl, whisk together the oats, flour, brown sugar, and cinnamon.
  5. Use a pastry cutter or fingertips to work the chilled butter into the dry mix until it 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 fruit juices bubble and topping is deep mahogany-brown.
  8. Allow the dessert to cool for 10 minutes before serving to set the glaze.
