Method
Prep & preheat
- Preheat the oven to 350F and generously grease a 9x13 baking dish so the crisp lifts cleanly after baking.
Make the apple filling
- Toss the apple slices with granulated sugar, brown sugar, cinnamon, nutmeg, allspice, cornstarch, and lemon juice until the fruit is evenly coated and looks slightly thickened.
- Spread the coated apples in the prepared dish in a thick, even layer so they bake down and bubble throughout.
Make the crumble topping
- Combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt, then work in the cold cubed butter by hand until the mixture forms large, butter-streaked clumps.
- Pour and spread the crumble topping generously over the apples, piling it thick so it crisps on top rather than sinking.
Bake
- Bake for 50-55 minutes until the topping is deeply golden and the apple filling bubbles all around at the edges and through the crumble.
Rest & serve
- Rest the crisp for 15 minutes before scooping so the juices set slightly and each portion holds together.
- Serve warm with vanilla ice cream or whipped cream for a creamy contrast to the caramelized crumble.
Notes
Pro tip: use a mix of apples that hold their shape (and cut consistently) so the filling turns jammy but not mushy. Refrigerate leftovers in a covered container for up to 4 days; reheat in a 350F oven until warmed through. Freezing is not recommended due to topping texture, but you can freeze baked portions for up to 1 month and re-crisp at 350F. For a lighter swap, reduce butter in the topping by half and replace with chilled coconut oil (texture will be slightly less crisp).
