Yields: 6-8 servings
Prep time: 25 minutes
Cook time: 40-45 minutes
Ingredients:
For the Apple Filling:
- 6-8 medium apples (such as Honeycrisp, Gala, or Fuji), peeled, cored, and sliced
- 1/4 cup granulated sugar
- 2 tablespoons all-purpose flour
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1 tablespoon lemon juice
- 1 tablespoon unsalted butter, cut into small pieces
For the Crumble Topping:
- 1 cup all-purpose flour
- 1 cup rolled oats (not instant)
- 3/4 cup packed light brown sugar
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/2 cup (1 stick) cold unsalted butter, cut into small cubes
Equipment:
- 9×13 inch baking dish
- Mixing bowls
- Pastry blender or fork
- Peeler, corer, and knife
Instructions:
Step 1: Prepare the Apples
- Combine the sliced apples, granulated sugar, flour, cinnamon, and nutmeg in a large bowl. Toss gently to coat the apples evenly. Stir in the lemon juice.

Step 2: Assemble the Filling
Pour the apple mixture into the 9×13-inch baking dish. Dot the top of the apples with the small pieces of butter.

Step 3: Make the Crumble Topping
In a separate medium bowl, whisk together the flour, rolled oats, brown sugar, cinnamon, and salt.

Step 4: Cut in the Butter
Add the cold, cubed butter to the dry ingredients. Use a pastry blender or your fingertips to cut the butter into the mixture until it resembles coarse crumbs. Some small pea-sized pieces of butter are okay and will contribute to a flaky topping.

Step 5: Sprinkle the Topping
Evenly sprinkle the crumble topping over the apple filling in the baking dish.

Step 6: Bake the Crumble
Preheat oven to 375°F (190°C). Bake for 40-45 minutes, or until the topping is golden brown and the apples are tender and bubbly. If the topping starts to brown too quickly, you can loosely tent the dish with aluminum foil.

Step 7: Cool and Serve
Let the apple crumble cool slightly before serving. It’s delicious served warm on its own or with a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of caramel sauce.
