Equipment
Method
Prep and preheat
- Preheat oven to 350F and position a rack in the center so the crisp bakes evenly.
Make the apple filling
- Toss the apples with both citrus zests, both juices, granulated sugar, cinnamon, and nutmeg, then spread them in a 14x9x2 inch baking dish.
Make the oat-and-butter crumble
- Combine all-purpose flour, both sugars, kosher salt, and old-fashioned oats, then add cold diced butter and work with your fingers until pea-sized clumps form.
Assemble and bake
- Scatter the crumble topping over the apples, covering every inch generously.
- Bake 55-60 minutes at 350F until the top is golden brown and the apples are tender and bubbling.
Serve
- Let the apple crisp cool briefly, then serve warm with vanilla ice cream or whipped cream.
Notes
Pro tip: Use very cold diced butter and stop mixing once you see pea-sized clumps—this keeps the topping from turning sandy. Store leftovers covered in the refrigerator up to 4 days; reheat in a 350F oven for 10–15 minutes to re-crisp. Freezing is yes for baked leftovers (cool completely, wrap tightly, freeze up to 2 months) and reheat from frozen. For a lighter swap, use half the butter by weight with an equal amount of cold coconut oil or a plant-based butter substitute (choose one that browns well).
