Prep and bake
  1. Preheat oven to 375F and grease a 9x13 baking dish with a light coating of butter or nonstick spray.
  2. Toss apple slices with granulated sugar, brown sugar, cinnamon, nutmeg, cornstarch, and lemon juice, then spread the spiced apples in the prepared dish.
  3. Combine rolled oats, flour, brown sugar, cinnamon, and salt, then cut in cold butter until large, chunky clumps form.
  4. Scatter the oatmeal crumble generously over the apples so every inch is covered.
  5. Bake 40-45 minutes until the topping is deeply golden and the apple filling bubbles at the corners.
Rest and serve
  1. Rest for 10 minutes to thicken the filling before serving.
  2. Serve warm with vanilla ice cream.

Notes

For best results, use cold butter for the crumble so it bakes into crisp clumps rather than a sandy mix. Store covered in the refrigerator up to 4 days; reheat individual portions in the oven or microwave until warmed. Freezing is yes—freeze baked portions up to 2 months and reheat from thawed. For a lighter option, use reduced-fat butter (or half replace with unsweetened applesauce) while keeping the bake time the same.
