Method
Preheat and fill
- Preheat the oven to 350°F and grease a 9x13 baking dish.
- Toss strawberries and peaches with granulated sugar, cornstarch, lemon juice, and vanilla extract, then spread the fruit evenly in the prepared dish.
Make the oat crumble topping
- Combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt, then cut in cold butter with your fingertips until the mixture resembles coarse crumbs with pea-sized pieces.
- Sprinkle the crumble topping evenly over the fruit so it covers the surface completely.
Bake and serve
- Bake for 38-42 minutes at 350°F until the topping is deep golden brown and the fruit is bubbling thickly around the edges (visual cue: caramel-colored crumble and active bubbling at the sides).
- Cool for 10 minutes, then serve warm with vanilla ice cream.
Notes
For the best thick filling, be sure the crumble is evenly scattered so it forms a barrier while baking; use fully fresh strawberries and peaches and bake until you see consistent bubbling along the edges. Store leftovers covered in the refrigerator up to 3 days; reheat in a 325°F oven until warmed through. Freeze baked crisp up to 2 months (best for topping, texture may soften slightly after thawing). For a dairy-free swap, use vegan butter in the crumble and choose dairy-free vanilla ice cream.
