Method
Preheat and fill the baking dish
- Preheat the oven to 350F while you prepare the apples.
- 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.
Make the oat-and-butter crumble
- Combine all-purpose flour, granulated sugar, light brown sugar, kosher salt, and old-fashioned oats in a bowl, then add the cold diced butter.
- Work the mixture with your fingers until it forms pea-sized clumps.
Bake and serve
- Scatter the crumble topping over the apples, covering every inch generously.
- Bake for 55-60 minutes at 350F until the top is golden brown and the apples are tender and bubbling.
- Serve warm with vanilla ice cream or whipped cream.
Notes
Pro tip: Use thickly sliced apples so they stay tender but still visible under the crisp topping. Refrigerate leftovers in an airtight container up to 4 days; rewarm in a 350F oven until hot through. Freezing is not recommended for best crumble texture. For a dairy-light option, use plant-based butter in the crumble.
