Servings and Timing

  • Cook Time: 35 minutes

  • Total Time: 35 minutes

  • Servings: This recipe serves approximately 6-8 people.

Variations

  • Fruit Variation: While blueberries are the star of this recipe, you can easily swap them for other berries like raspberries, blackberries, or strawberries. You could even make a mixed berry crumble for added variety.

FAQs

1. Can I make this blueberry crumble ahead of time?

2. Can I use frozen blueberries for this recipe?

Yes, frozen blueberries will work perfectly for this crumble. Just make sure to thaw them before using, or increase the baking time slightly if they are still frozen when added to the dish.

3. Can I use a different type of sugar?
