Ingredients

Scale
  • 6 medium fresh peaches, peeled, pitted, and sliced (about 1/2-inch thick)
  • 1/4 cup granulated sugar (50 g)
  • 1 tablespoon fresh lemon juice
  • 1 tablespoon cornstarch
  • 1 cup old-fashioned rolled oats (90 g)
  • 3/4 cup all-purpose flour (95 g)
  • 1/2 cup packed brown sugar (100 g)
  • 1 teaspoon ground cinnamon
  • Pinch of salt
  • 1/2 cup cold unsalted butter, cut into small cubes (115 g)

Instructions

  1. Preheat the oven to 350°F (175°C).
  2. Peel and slice the peaches into roughly 1/2-inch thick slices. Toss them gently in a large bowl with granulated sugar, lemon juice, and cornstarch. Set aside for 10 minutes to let the sugar draw out the juice.
  3. Optional: Toast the rolled oats in a dry skillet over medium heat for 3-4 minutes, stirring often until lightly browned and fragrant.
  4. In a medium bowl, mix the toasted oats with all-purpose flour, brown sugar, ground cinnamon, and salt. Add the cold, cubed butter and use a pastry cutter or fingertips to cut the butter into the dry ingredients until the mixture resembles coarse crumbs.
  5. Transfer the peach mixture into an 8×8-inch baking dish, spreading it out evenly. Sprinkle the oat crumble topping evenly over the peaches without packing it down.
  6. Bake on the middle rack for 35-40 minutes until the topping is golden brown and crunchy and the peach juices are bubbling.
  7. Let the crisp cool for at least 10 minutes before serving to allow the juices to set slightly. Serve warm, optionally with vanilla ice cream or whipped cream.

Notes

If topping browns too quickly, tent with foil halfway through baking. For juicier peaches, increase cornstarch up to 2 tablespoons. To make gluten-free, substitute all-purpose flour with almond or gluten-free flour blend and use certified gluten-free oats. For dairy-free, replace butter with coconut oil or plant-based butter. Frozen peaches can be used if fresh are unavailable; thaw and drain excess liquid before use.
