Ingredients:

  • 6 cups (900g) peeled and sliced fresh peaches
  • 1/4 cup (50g) packed light brown sugar
  • 2 tbsp (16g) cornstarch
  • 1 tsp (2.6g) ground cinnamon
  • 1 tbsp (15ml) lemon juice
  • 1/4 tsp (1.5g) salt
  • 1 cup (125g) all-purpose flour
  • 1 cup (90g) rolled oats
  • 1/2 cup (100g) packed light brown sugar
  • 1/2 cup (113g) cubed cold unsalted butter
  • 1/2 tsp (1.3g) ground cinnamon
  • 1/4 tsp (1.5g) salt

Instructions:

  1. Preheat your oven to 375°F (190°C).
  2. In a large mixing bowl, toss the sliced peaches with lemon juice, brown sugar, cornstarch, cinnamon, and salt until coated in a glaze.
  3. Transfer the peach mixture into a 9-inch square baking dish or cast-iron skillet, spreading it evenly.
  4. In a medium bowl, whisk together the flour, oats, brown sugar, cinnamon, and salt.
  5. Add the cold, cubed butter to the flour mixture. Use a pastry cutter or fingertips to rub the butter into the dry ingredients until it resembles coarse sand with pea-sized clumps.
  6. Sprinkle the oat crumble mixture evenly over the peaches, ensuring the entire surface is covered.
  7. Bake for 35–40 minutes until the topping is deep mahogany gold and the peach juices are bubbling thick around the edges.
