Difficulty Level
Easy to Medium
Ingredients
- For the Apple Filling:
- 6 medium firm apples (such as Granny Smith, Braeburn, or Pink Lady), peeled, cored, and thinly sliced
- 1/2 cup granulated sugar
- 1 tbsp fresh lemon juice
- 1 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 1 tbsp all-purpose flour
- For the Oat Topping:
- 1 cup old-fashioned rolled oats
- 3/4 cup all-purpose flour, sifted
- 1/2 cup packed light brown sugar
- 1/2 tsp ground cinnamon
- 1/4 tsp salt
- 1/2 cup unsalted butter, chilled and cubed
Instructions
- Prepare the apples: In a large mixing bowl, toss the sliced apples with lemon juice, sugar, cinnamon, nutmeg, and flour. This mixture not only enhances the sweet and tangy profile but also thickens the natural juices released during baking.
- Make the oat topping: In a separate bowl, combine rolled oats, sifted flour, brown sugar, cinnamon, and salt. Add the chilled butter cubes and gently rub them between your fingers until the mixture resembles coarse crumbs. For an extra crisp touch, avoid overmixing to keep small butter bits intact.
- Assemble the crumble: Transfer the apple mixture into a greased 9-inch baking dish, spreading it evenly. Sprinkle the oat topping generously over the apples, ensuring full coverage for a golden crust.
- Bake to perfection: Preheat your oven to 350°F (175°C). Place the crumble on the middle rack and bake for 40-45 minutes, or until the topping turns a rich golden brown and the apple filling bubbles tantalizingly around the edges.
- Rest before serving: Allow the crumble to cool for 10-15 minutes. This resting time helps the juices thicken slightly, offering a lavishly juicy yet firm filling that contrasts beautifully with the crisp topping.
Expert Tips for Success
- Choosing the right apples is pivotal-Granny Smith adds tartness while Braeburn and Pink Lady offer sweetness and hold their shape well. Combining two varieties ups the flavor complexity.
- Use cold butter for the topping to create a crumbly, flaky texture. You can even grate the butter for faster,more even distribution.
- for a nutty crunch, add 1/3 cup chopped toasted walnuts or pecans to the oat topping.
- To keep the topping crisp longer, bake on a baking sheet to collect any drips that might burn or smoke.
- This crumble is perfect for making ahead-store uncovered in the fridge and reheat at 325°F (160°C) for 15 minutes to restore crispness.
Serving Suggestions
Serve your crumble warm, topped with a scoop of vanilla bean ice cream or a dollop of whipped cream. A drizzle of homemade caramel sauce or a sprinkle of toasted cinnamon sugar elevates the experience. For a refreshing twist, accompany with a side of bright lemon zest or a few fresh berries to cut through the richness.
