Ingredients:

  • 6 cups (900g) fresh peaches, peeled and sliced
  • 1/3 cup (65g) granulated sugar
  • 1 tbsp (8g) cornstarch
  • 1 tsp (2g) ground cinnamon
  • 1 tbsp (15ml) fresh lemon juice
  • 1 cup (90g) old-fashioned rolled oats
  • 1 cup (125g) all-purpose flour
  • 1/2 cup (100g) light brown sugar, packed
  • 1/2 cup (113g) cold unsalted butter, cubed
  • 1/4 tsp (1.5g) salt

Instructions:

  1. Toss the sliced peaches with lemon juice, granulated sugar, cinnamon, and cornstarch in a large bowl.
  2. Stir gently to ensure every slice is coated.
  3. Pour the mixture into a 9x9 inch baking dish, spreading it evenly, and let it sit for 5 minutes.
  4. In a separate bowl, whisk together the oats, flour, brown sugar, and salt.
  5. Add the cold, cubed butter. Use a pastry cutter or fork to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized lumps remaining.
  6. Sprinkle the crumble evenly over the peaches, avoiding pressing it down to maintain aeration.
  7. Preheat your oven to 375°F (190°C).
  8. Bake for 35–40 minutes until the fruit juices are bubbling vigorously around the edges and the topping is deep golden brown.
