- 1 Sheet pan (optional, to catch drips)
- 1 Aluminum foil (optional, for tenting)
Ingredients
Apple Filling
- 6 medium firm apples peeled, cored, and sliced 1/4 inch thick; mix of Granny Smith, Honeycrisp, Braeburn, Pink Lady
- 1 tbsp lemon juice
- 0.25 cup granulated sugar adjust to taste
- 1.5 tbsp cornstarch or 2 tbsp all-purpose flour
- 1.5 tsp ground cinnamon plus more to taste
- 0.25 tsp ground nutmeg or cardamom
- 0.25 tsp fine sea salt

- 0.5 cup cold unsalted butter diced
- 0.5 cup chopped pecans or walnuts optional
Instructions
Preheat and Prep the Pan
- Heat oven to 350°F (175°C). Lightly butter a 9-inch square or similar 2-quart baking dish.
Toss the Apple Filling
- In a large bowl, combine sliced apples, lemon juice, granulated sugar, cornstarch, cinnamon, nutmeg, salt, and vanilla. Toss until the apples are evenly coated and glossy. Spread the apples into the prepared baking dish.
Mix the Crumble Topping
- In another bowl, stir together oats, flour, brown sugar, cinnamon, and salt. Cut in the cold butter with a pastry cutter or your fingers until it forms moist, sandy clumps with some pea-sized bits. Stir in nuts if using. Chill 10 minutes for extra crunch.
Assemble
- Scatter the chilled topping evenly over the apples, leaving some craggy peaks for maximum crunch.
Bake
- Bake 40 to 45 minutes, until the topping is deeply golden and the apple juices are bubbling around the edges. If the top browns too quickly, tent loosely with foil for the last 10 minutes.
Rest and Serve
- Let the crumble cool 10 to 15 minutes so the juices thicken. Serve warm with vanilla ice cream, whipped cream, or warm custard.

Step-by-Step Instructions to Make Baked Apple Crumble
Preheat and Prep the Pan
Heat oven to 350°F (175°C). Lightly butter a 9-inch square or similar 2-quart baking dish.
Toss the Apple Filling
In a large bowl, combine sliced apples, lemon juice, granulated sugar, cornstarch, cinnamon, nutmeg, salt, and vanilla. Toss until the apples are evenly coated and glossy. Spread into the prepared dish.
Mix the Crumble Topping
In another bowl, stir oats, flour, brown sugar, cinnamon, and salt. Cut in the cold butter with a pastry cutter or fingers until it forms moist, sandy clumps with some pea-sized bits. Stir in nuts if using. Chill 10 minutes for extra crunch.
Assemble
Scatter the chilled topping evenly over the apples, leaving some craggy peaks for maximum crunch.
Bake
Bake 40 to 45 minutes until the topping is deeply golden and the apple juices are bubbling around the edges. If the top browns too quickly, tent loosely with foil for the last 10 minutes.
Rest and Serve
Let the crumble cool 10 to 15 minutes so the juices thicken. Serve warm with vanilla ice cream, whipped cream, or warm custard.
Tips for Success
- Use a mix of tart and sweet apples for layered flavor.
- Slice apples evenly so they cook at the same rate.
- Chill the topping before baking for extra crispness.
- Bake until you see active bubbling at the edges; that means the filling has thickened.
- Set the dish on a sheet pan to catch any drips and keep the oven tidy.
Variations of Baked Apple Crumble
- Caramel Apple Crumble: drizzle 2 to 3 tbsp salted caramel over the apples before adding the topping.

My favorite fall ritual is pulling this crumble from the oven and hearing the quiet bubble of apple juices. We pass spoons, scoop ice cream, and the first bite always brings a little happy silence before the smiles.
FAQs
What are the best apples for crumble? A mix is best. Use tart Granny Smith for structure, plus a sweeter apple like Honeycrisp or Braeburn for balance.
How do I keep the topping crisp? Start with cold butter, chill the topping, and bake until the filling actively bubbles. If needed, broil 1 minute at the end, watching closely.
Can I make it ahead? Assemble the filling and topping separately up to 24 hours ahead. Refrigerate both. Top and bake just before serving.
How do I make it gluten-free or dairy-free? Use 1:1 gluten-free flour and certified GF oats. For dairy-free, use vegan butter or solid coconut oil.
Can I reduce the sugar? Yes. Cut each sugar by 2 to 3 tbsp. If lowering sugar in the filling, add a bit more cornstarch so the juices still thicken.
