Classic Apple Crumble

Apple crumble is one of the simplest and most comforting desserts you can make. There is no pastry to roll and no special skills required. Tender, cinnamon-scented apples bake beneath a golden, buttery topping with crunchy oats. Serve it warm with ice cream or custard, and watch it disappear.

Ingredients

For the apple filling
– 6 medium apples (about 2 1/2 lb / 1.1 kg), a mix of tart and sweet
– 1/3 cup (65 g) brown sugar
– 1 tablespoon lemon juice
– 1 tablespoon cornstarch or all-purpose flour
– 1 1/2 teaspoons ground cinnamon
– 1/4 teaspoon ground nutmeg
– 1 teaspoon vanilla extract
– Pinch of salt

For the crumble topping
– 3/4 cup (95 g) all-purpose flour
– 3/4 cup (70 g) old-fashioned rolled oats
– 1/2 cup (100 g) brown sugar
– 1/2 teaspoon ground cinnamon
– 1/4 teaspoon salt
– 1/2 cup (115 g) cold unsalted butter, cut into cubes
– 1/3 cup (40 g) chopped pecans or walnuts, optional

Step-by-Step Instructions

1. Preheat the oven to 375°F (190°C) and grease a 9×9-inch (23×23 cm) or similar 2-quart baking dish.
2. Prepare the apples. Peel, core and slice the apples about 1/4 inch (6 mm) thick. Toss them in a large bowl with the brown sugar, lemon juice, cornstarch, cinnamon, nutmeg, vanilla and salt. Spread evenly in the baking dish.
3. Make the crumble. In another bowl, combine the flour, oats, brown sugar, cinnamon and salt. Add the cold butter and rub it in with your fingertips, or cut it in with a pastry blender, until the mixture forms clumps of different sizes. Stir in the nuts if using.
4. Top the apples. Scatter the crumble evenly over the apples, squeezing some of it into larger clumps for extra crunch.
5. Bake. Bake for 35 to 45 minutes, until the topping is deep golden and the fruit is bubbling at the edges. A knife should slide easily into the apples.
6. Rest. Let it cool for 15 minutes so the juices thicken slightly before serving.

Best Apples for Crumble

Use a mix for the most interesting flavor and texture. Tart apples like Granny Smith keep their shape and add tang, while sweeter varieties like Honeycrisp, Gala, Braeburn or Pink Lady soften and add natural sweetness.

Tips for Success

• Keep the butter cold. Cold butter creates crunchy, crumbly clusters rather than a greasy, sandy topping.
• Slice the apples evenly so they cook at the same rate.
• Place a baking sheet underneath to catch any bubbling juices.
• Chill the topping for 10 minutes before baking for extra-crisp clumps.

Variations

• Apple and blackberry: Add 1 cup blackberries to the filling, a British classic.
• Pear crumble: Use ripe but firm pears and add a little fresh ginger.
• Gluten-free: Use certified gluten-free oats and replace the flour with almond flour or a gluten-free flour blend.
• Individual crumbles: Divide among ramekins and bake for 25 to 30 minutes.

Make-Ahead and Storage

Prepare the filling and topping separately up to a day ahead and refrigerate. Assemble just before baking. Leftover crumble keeps covered in the refrigerator for up to 4 days. Reheat in a 350°F (175°C) oven for 15 minutes to re-crisp the topping.

Frequently Asked Questions

What is the difference between a crumble and a crisp?
In the United States, a crisp usually contains oats in its topping, while a crumble may not. In the United Kingdom, crumble is the general name for both. In practice, they are very similar.

Can I freeze apple crumble?
Yes. Freeze it unbaked, covered tightly, for up to 3 months. Bake from frozen at 375°F (190°C), adding about 15 to 20 minutes.

Vanilla ice cream, whipped cream, custard or a spoon of thick Greek yogurt.
