🔪How To Make This Easy Blueberry Crumble Recipe?
- Step 1: Preheat the oven to 350 degrees Fahrenheit. Rinse and drain the blueberries and be sure to remove any stems from the blueberries.
- Step 2: Take a 9 by 9-inch or a 9 by 13-inch baking dish, and mix together the blueberries, maple syrup, cornstarch, lemon zest, lemon juice, and cinnamon.
- Step 3: In a medium bowl, stir together the oats, vanilla almond granola, brown sugar, and salt. Mix in the butter. Pour the oat mixture over the fruit filling and place the remaining 4 tablespoons of cold butter on top of the mixture.
- Step 4: Bake for 45 minutes or until bubbly, crisp, and golden brown. Serve your Blueberry Crumble with vanilla ice cream.
💡Hint: Let it cool 10 minutes before serving—this helps the filling set and keeps scoops from sliding everywhere.
👩🍳 Expert Tips
- Frozen Berries? Use them straight from the freezer—but add 1 extra teaspoon of cornstarch to help absorb moisture.
- Don’t Skimp on Zest: The lemon zest brightens everything. I use a microplane for super-fine flecks.
- Watch the Edges: If they’re bubbling too fast, tent loosely with foil to prevent overbrowning.
💭 FAQs
Yes, frozen blueberries work wonderfully in this recipe. There's no need to thaw them; just use them straight from the freezer. This helps maintain their shape and prevents the filling from becoming too watery.
To keep the topping crisp, ensure that the blueberry filling is properly thickened. Using cornstarch or flour helps achieve this. Also, baking the crumble until the topping is golden brown and the filling is bubbly will help in achieving the desired texture.
Store any leftover blueberry crumble in an airtight container in the refrigerator. It will stay fresh for about 2-3 days. Reheat individual servings in the microwave or enjoy them cold.
Absolutely! Many fruits pair well with blueberries. Consider adding sliced peaches, blackberries, raspberries, or even rhubarb for a unique twist. Just ensure the total fruit volume remains consistent with the recipe to maintain the right balance of filling and topping.
