Prep and fill
- Preheat the oven to 375°F (190°C) so it’s fully hot before baking. Place a sheet pan in the oven if you want to catch any drips from the baking dish.
- Grease a 9-inch baking dish to prevent sticking. Set it aside while you mix the fruit.
- In a large bowl, combine peaches, strawberries, granulated sugar, cornstarch, lemon juice, and vanilla extract until evenly coated. The cornstarch should look evenly distributed.
- Transfer the fruit mixture to the greased baking dish and spread it into an even layer. This helps the filling bubble uniformly.
Make the crisp topping and bake
- In a separate bowl, combine old-fashioned oats, all-purpose flour, brown sugar, cinnamon, and salt. Mix until the dry ingredients look consistent.
- Stir in the melted unsalted butter until the mixture forms crumbly clumps. If it looks dry, keep stirring until all flour is moistened.
- Sprinkle the topping evenly over the fruit so it covers the surface. Aim for an even layer for golden, crisp texture.
- Bake at 375°F (190°C) for 40–45 minutes until golden and bubbly. The center should be bubbling and the topping should look crisp.
Cool and serve
- Cool the crisp for 10 minutes before serving to let the juices thicken slightly. You should see less active bubbling when it’s ready.
- Serve warm as-is, or with vanilla ice cream if desired. The hot fruit and cold topping create contrast.
Notes
For the best thick, jammy filling, use ripe peaches and let the crisp cool 10 minutes before scooping. Store leftovers covered in the refrigerator up to 4 days; reheat in a 325°F (165°C) oven until warmed through. Freezing is not recommended because the fruit topping can soften after thawing. Dietary swap: use a 1:1 gluten-free all-purpose flour blend to make the topping gluten-free.
