Ingredients
- 6 medium fresh apples (about 2 pounds, 900g), peeled, cored, and sliced
- 2 tablespoons granulated sugar
- 1 teaspoon ground cinnamon
- 1 tablespoon lemon juice
- 1 cup rolled oats (90g)
- 1/2 cup all-purpose flour (65g)
- 1/2 cup brown sugar, packed (100g)
- 1/2 cup chopped nuts (walnuts or pecans) (50g)
- 1/4 teaspoon salt
- 1/2 cup unsalted butter (1 stick, 113g), cold and cubed
Instructions
- Prepare the apples Preheat the oven to 350°F (175°C). In a large bowl, toss the sliced apples with granulated sugar, ground cinnamon, and lemon juice until coated evenly. Transfer to a 9-inch baking dish.
- Make the oat and nut topping In a separate bowl, combine the rolled oats, flour, brown sugar, chopped nuts, and salt. Add the cold cubed butter and use your fingers or a pastry cutter to mix until the mixture resembles coarse crumbs.
- Assemble and bake Sprinkle the oat and nut mixture evenly over the apples in the baking dish. Bake uncovered in the preheated oven for 35 to 40 minutes, until the topping is golden brown and the apples are bubbling.
- Cool and serve Remove from oven and let cool for at least 10 minutes before serving. This resting time helps the filling set slightly for easier portioning.
Helpful Tips
- Use tart apples like Granny Smith or Honeycrisp for a balanced flavor that holds up well during baking.
- Chilling the butter before mixing helps achieve a crumbly, crisp topping texture.
- Allow the crumble to cool before storing to avoid condensation which can make the topping soggy.
- For extra flavor, add a pinch of nutmeg or cloves to the apple mixture.
Storage and Make-Ahead
Store leftover apple crumble in an airtight container in the refrigerator for up to 3 days.
Reheat individual portions in the microwave until warmed through or in a 350°F (175°C) oven for 10 minutes to restore crispness.
Do not freeze after baking as the topping texture may degrade.
