Prep and bake
- Preheat oven to 350F and generously grease a 9x13 baking dish so the crisp releases cleanly.
- Toss apple slices with granulated sugar, brown sugar, cinnamon, nutmeg, allspice, cornstarch, and lemon juice until evenly coated, then spread them in the baking dish in a thick layer.
- Combine rolled oats, all-purpose flour, brown sugar, cinnamon, and salt, then work in the cold cubed unsalted butter with your hands until the mixture forms large, butter-streaked clumps.
- Pour and spread the crumble topping generously over the apples, piling it thick for maximum crunch.
- Bake 50-55 minutes at 350F until the topping is deeply golden and the apple filling bubbles all around.
Serve
- Rest 15 minutes, letting the bubbling juices thicken so the crisp scoops without collapsing.
- Serve with vanilla ice cream or whipped cream.
Notes
Tip: use a thick, even apple layer so the filling bubbles consistently under the oat clumps. Store covered in the refrigerator for up to 4 days and reheat individual portions in the oven at 350F until warmed through. Freeze baked crisp for up to 2 months; thaw overnight in the fridge and reheat. For a lighter option, swap half the butter in the topping for an equal amount of a 1:1 baking butter substitute if desired.
