For the filling:
- 6 large apples (a mix of Granny Smith and Honeycrisp), peeled, cored, and sliced
- 1 tbsp lemon juice
- ½ cup granulated sugar
- 1 tsp ground cinnamon
- ¼ tsp ground nutmeg
For the crumble topping:
- 1 cup all-purpose flour
- ½ cup rolled oats
- ½ cup packed brown sugar
- ½ cup unsalted butter, cold and cubed
- 1 pinch of salt
Pro tip: Cold butter is key — it gives you that irresistible crumbly texture instead of a soggy topping.
