Ingredients:
- 2 lbs (900g) fresh peaches, peeled and sliced
- 1/2 cup (100g) granulated sugar
- 1 tbsp (15ml) lemon juice
- 1 tbsp (8g) cornstarch
- 1/2 tsp (1g) 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 light brown sugar
- 1/2 cup (113g) unsalted butter, cold and cubed
- 1/2 tsp (1g) ground cinnamon
- 1/4 tsp (1.5g) salt
Instructions:
- Preheat your oven to 375°F (190°C).
- In a medium bowl, toss the sliced peaches with granulated sugar, lemon juice, cornstarch, cinnamon, and salt.
- Stir gently until the peaches are evenly coated and the cornstarch has dissolved.
- Transfer the mixture into a 9x9 inch baking dish, spreading it into an even layer.
- In a large mixing bowl, whisk together the oats, flour, brown sugar, cinnamon, and salt.
- Add the cold, cubed butter.
- Use a pastry cutter or forks to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized lumps remaining.
- Scatter the crumble evenly over the peaches, avoiding pressing the topping down.
- Place the dish on a baking sheet and bake for 30–35 minutes until the topping is deep mahogany-gold and the peach juices bubble thick and slow around the edges.
- Remove from the oven and let it rest for 10 minutes to allow the filling to set.
