This recipe delivers warm, juicy peaches beneath a perfectly crisp, buttery oat topping. It is a simple, comforting dessert that works well with fresh or frozen peaches and is best served warm with vanilla ice cream.

Ingredients

Scale
  • 6 cups fresh or frozen peach slices (about 8 medium peaches)
  • 1/2 cup granulated sugar
  • 1 tablespoon lemon juice
  • 1 tablespoon cornstarch
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 cup all-purpose flour
  • 1 cup rolled oats
  • 3/4 cup packed light brown sugar
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) cold unsalted butter, cut into small pieces

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch baking dish.
  2. In a large bowl, gently toss the peach slices with the granulated sugar, lemon juice, cornstarch, cinnamon, and nutmeg until the peaches are evenly coated.
  3. Pour the peach mixture into the prepared baking dish and spread it into an even layer.
  4. In a separate medium bowl, combine the flour, rolled oats, brown sugar, and salt for the topping.
  5. Cut in the cold butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs. Do not overmix; you want some pea-sized pieces of butter remaining for crispness.
  6. Sprinkle the oat topping evenly over the peach filling.
  7. Bake for 35 to 45 minutes, or until the topping is golden brown and the peach filling is bubbly and thick around the edges.
  8. Let the peach crisp cool on a wire rack for at least 15 minutes before serving. This allows the filling to set slightly.
  9. Serve warm, ideally with a scoop of cold vanilla ice cream.

Notes

  • If you use frozen peaches, do not thaw them first. You may need to add 5 to 10 minutes to the baking time.
  • For an extra crunchy topping, add 1/4 cup of chopped pecans or walnuts to the oat mixture.
  • This dessert pairs well with a chilled, slightly sweet white wine, such as a late-harvest Riesling.
