Notes
Storage: Cool completely, cover, and refrigerate for up to 4 days. Reheat individual portions in the microwave or the entire dish in a 350°F oven until warm. Make-Ahead: Assemble the crumble up to the baking step, cover, and refrigerate for up to 24 hours. Add 5-10 minutes to the baking time if starting from cold. Variations: Use pears or a mix of apples and pears. For a gluten-free version, use a 1:1 gluten-free flour blend and certified gluten-free oats. For extra crunch, add 1/4 cup chopped pecans or walnuts to the topping.
