Method
Prep the oven and fruit
- Preheat oven to 350F and grease a 9x13 baking dish so the peach filling releases easily.
- Toss sliced fresh peaches with granulated sugar, lemon juice, cornstarch, and cinnamon, then spread the mixture in the baking dish in an even layer.
Make the oat crumble
- Combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt in a bowl.
- Cut cold unsalted butter into the dry ingredients with your fingers until large, crumbly clumps form and the mixture looks sandy but holds together when pressed.
- Scatter the oat topping evenly over the peach filling, covering completely so it bakes into a golden crust.
Bake and serve
- Bake for 35-40 minutes at 350F until the topping is deeply golden and the peach filling is bubbling at the edges, showing active simmering through the crumble.
- Serve warm with vanilla ice cream or heavy cream.
Notes
For the crispiest topping, spread the crumble in a fully even layer so every corner gets direct heat, and let the crisp sit 10 minutes after baking to thicken the bubbling juices. Store covered in the refrigerator up to 3 days; reheat in a 350F oven until warmed through. Freezing: no recommended for best texture. Dietary swap: for a gluten free peach crisp, substitute a 1:1 gluten free flour blend for the all-purpose flour (check label for cup-for-cup use).
