Method
Prep and heat
- Preheat oven to 375F, then grease a 9x13 baking dish.
Season the apple filling
- Stir cinnamon, nutmeg, allspice, and lemon juice into the canned apple pie filling, then spread it evenly in the prepared dish.
Make the oat crumble
- Combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt, then cut in cold cubed butter until chunky clumps form.
Bake
- Scatter the crumble generously over the apple filling, then bake for 30-35 minutes until the topping is golden and the filling bubbles around the edges.
Rest and serve
- Rest for 5 minutes, then serve warm with vanilla ice cream.
Notes
For the crispiest topping, keep the butter cold and stop mixing once chunky clumps form—no need to make it uniform. Refrigerate leftovers in a covered container for up to 4 days; reheat in a 350F oven until warmed through. Freezing is not recommended for best texture. If you want a lighter option, use reduced-fat butter for the crumble (texture will be slightly less crisp).
