Equipment
Method
Preheat & prep the dish
- Preheat the oven to 350F, with a rack in the middle position so the crisp browns evenly.
Make the apple filling
- Toss the sliced apples with orange zest, lemon zest, orange juice, lemon juice, granulated sugar, cinnamon, and nutmeg, then spread them in a 14x9x2 inch baking dish.
- Press the apples into an even layer so the juices bubble up across the full surface during baking.
Make the crumble topping
- Combine all-purpose flour, granulated sugar, light brown sugar, kosher salt, and old-fashioned oats in a bowl.
- Add the cold diced butter and work it with your fingers until the mixture forms pea-sized clumps, leaving some larger bits for extra crunch.
Assemble & bake
- Scatter the crumble topping over the apples, covering every inch generously so no apple peaks through.
- Bake for 55-60 minutes at 350F until the top is golden brown and the apples are tender and bubbling.
Serve
- Serve warm with vanilla ice cream or whipped cream.
Notes
For the best crumble texture, keep the butter cold while you pinch it into pea-sized clumps. Store leftovers covered in the refrigerator up to 4 days; reheat in a 350F oven or microwave until warmed through. Freezing is yes—freeze portions tightly wrapped up to 2 months and thaw in the fridge before reheating. For a lighter option, use half whole-wheat flour for the all-purpose flour while keeping the same topping structure.
