Ingredients:

  • 6 cups (900g) fresh peaches, sliced
  • 1/4 cup (50g) brown sugar, packed
  • 2 tbsp (16g) cornstarch
  • 1 tsp (2g) ground cinnamon
  • 1 tbsp (15ml) fresh lemon juice
  • 1/4 tsp (1.5g) salt
  • 1 cup (90g) old-fashioned rolled oats
  • 3/4 cup (95g) all-purpose flour
  • 1/2 cup (100g) brown sugar, packed
  • 1/2 cup (113g) unsalted butter, cold and cubed
  • 1 tsp (2g) ground cinnamon
  • 1/4 tsp (1.5g) salt

Instructions:

  1. Preheat your oven to 400°F (200°C).
  2. In a large bowl, toss the sliced peaches with brown sugar, cornstarch, cinnamon, lemon juice, and salt.
  3. Transfer the mixture into a 9-inch cast-iron skillet or baking dish, spreading the fruit into an even layer.
  4. In a separate bowl, whisk together the oats, flour, brown sugar, cinnamon, and salt.
  5. Add the cold, cubed butter. Use a pastry cutter or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized lumps remaining.
  6. Sprinkle the topping evenly over the peaches, pressing down very lightly to ensure the topping adheres to the fruit.
  7. Place the dish on the center rack and bake for 20–25 minutes until the edges are bubbling and the topping is deep mahogany-gold.
  8. Allow the crisp to rest for 10 minutes before serving to let the filling set.
