Ingredients

Scale
  • 6 medium fresh peaches, peeled and sliced (about 900g / 2 lbs)
  • ½ cup granulated sugar (100g)
  • ¼ cup packed brown sugar (50g)
  • 1 tablespoon lemon juice (15ml)
  • 2 tablespoons cornstarch (16g)
  • 1 teaspoon ground cinnamon
  • ½ teaspoon ground nutmeg
  • 1 teaspoon pure vanilla extract
  • 1 cup old-fashioned rolled oats (90g)
  • ¾ cup all-purpose flour (90g)
  • ⅓ cup packed brown sugar (65g)
  • 1 teaspoon ground cinnamon
  • Pinch of salt
  • ½ cup cold unsalted butter, cubed (115g / 1 stick)
  • 1 tablespoon maple syrup (15ml) (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease an 8×8 inch (20×20 cm) baking dish with butter or non-stick spray.
  2. Peel and slice the peaches into roughly ½-inch (1.3 cm) thick pieces using a sharp paring knife.
  3. In a large bowl, combine the sliced peaches, granulated sugar, brown sugar, lemon juice, cornstarch, cinnamon, nutmeg, and vanilla extract. Toss gently until peaches are evenly coated.
  4. Transfer the peach mixture to the prepared baking dish and spread evenly.
  5. In a medium bowl, mix rolled oats, flour, brown sugar, cinnamon, and salt. Add the cold cubed butter and cut it into the dry ingredients using a pastry cutter or two forks until the mixture resembles coarse crumbs.
  6. Drizzle in the maple syrup and stir quickly to combine.
  7. Sprinkle the oat streusel topping evenly over the peaches without pressing down.
  8. Bake for 40-45 minutes until the topping is golden brown and crisp and the peach juices are bubbling around the edges. If the topping browns too quickly, tent loosely with aluminum foil for the last 10 minutes.
  9. Let the crisp cool for at least 15 minutes before serving to allow the filling to thicken.

Notes

Keep the butter cold for a crunchy topping. Use cornstarch to thicken the peach juices and prevent sogginess. Uniform peach slices ensure even cooking. If topping browns too fast, tent with foil. Frozen peaches can be used if thawed and drained well. For gluten-free, substitute flour with almond or gluten-free flour blend. For vegan, use coconut oil instead of butter and maple syrup instead of brown sugar.
