Ingredients:
- 6 cups (900g) fresh peaches, peeled and sliced
- 1/4 cup (50g) granulated sugar
- 1 tbsp (8g) cornstarch
- 1 tsp (2g) ground cinnamon
- 1 tbsp (15ml) lemon juice
- 1 cup (90g) old-fashioned rolled oats
- 1 cup (125g) all-purpose flour
- 1 cup (200g) packed brown sugar
- 1/2 tsp (3g) salt
- 1/2 cup (115g) unsalted butter, chilled and cubed
Instructions:
- Preheat your oven to 375°F (190°C).
- In a large bowl, toss the sliced peaches with granulated sugar, cornstarch, cinnamon, and lemon juice. Stir gently until the fruit is evenly coated in a cloudy glaze.
- Pour the peach mixture into a 9x9 inch square pan or a 10-inch cast-iron skillet, spreading it into an even layer.
- In a medium bowl, whisk together the oats, flour, brown sugar, and salt.
- Add the chilled, cubed butter. Using a pastry blender or your fingers, work the butter into the dry ingredients until the mixture looks like coarse crumbs (roughly the size of peas).
- Sprinkle the oat mixture evenly over the peaches, pressing down very lightly just to ensure contact.
- Bake for 30 minutes until the filling bubbles vigorously around the edges and the topping turns a deep, mahogany gold.
