Method
Preheat and prepare baking dish
- Preheat oven to 375F and grease a 9x13 baking dish.
- Set the baking dish aside while you prepare the apple filling.
Make the spiced apple filling
- Toss apple slices with granulated sugar, brown sugar, cinnamon, nutmeg, cornstarch, and lemon juice.
- Spread the coated apples in the prepared dish in an even layer.
Assemble the oatmeal crumble
- Combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt.
- Cut cold unsalted butter into the oat mixture with your fingertips or a pastry cutter until large, chunky clumps form.
- Scatter the crumble generously over the apples so every inch is covered.
Bake and serve
- Bake for 40-45 minutes until the topping is deeply golden and the apple filling bubbles at the corners.
- Rest for 10 minutes, then serve warm with vanilla ice cream.
Notes
Pro tip: for the best chunky crumble, keep the butter cold and work it in just until you get clumps, not a fine sand. Refrigerate leftovers covered for up to 3 days; rewarm in a 350F oven until hot. Freezing is yes—freeze individual portions wrapped well and reheat from frozen. Dietary swap: replace unsalted butter with a 1:1 vegan butter for a dairy-free version.
