Method
Preheat and season the filling
- Preheat the oven to 375°F and grease a 9x13 baking dish. Set aside while you mix the filling.
- Stir the cinnamon, nutmeg, allspice, and lemon juice into the canned apple pie filling to brighten and season it, then spread it evenly in the prepared dish.
Make the oat crumble
- Combine the rolled oats, all-purpose flour, brown sugar, cinnamon, and salt. Cut in the cold cubed butter until chunky clumps form.
- Scatter the oat crumble generously over the apple filling, covering it as evenly as possible.
Bake and rest
- Bake for 30–35 minutes at 375°F until the topping is golden and the filling is bubbling around the edges. If needed, rotate the pan once for even browning.
- Rest for 5 minutes before serving warm. Serve with vanilla ice cream.
Notes
Pro tip: press the crumble lightly with your fingertips so it bakes into chunky clusters instead of fine crumbs. Store covered in the refrigerator up to 4 days; reheat individual portions in the microwave until warm. Freezing is not recommended because the canned filling can soften when thawed. For a lower-sugar option, use a reduced-sugar brown sugar substitute in the crumble.
