Blueberry Crumble Recipe

Ingredients:

• For the Filling:
  • 4 cups fresh or frozen blueberries
  • 1/4 cup white sugar
  • 1/4 cup brown sugar
  • 1 tablespoon cornstarch or flour
  • 1 tablespoon lemon juice
  • 1/2 teaspoon vanilla extract
  • A pinch of salt
• For the Crumble Topping:
  • 1 cup rolled oats (old-fashioned)
  • 1/2 cup flour (all-purpose or almond flour for a gluten-free version)
  • 1/3 cup brown sugar
  • 1/4 teaspoon ground cinnamon
  • A pinch of salt
  • 1/2 cup cold butter, cubed
  • 1/4 cup chopped nuts (optional, like almonds or walnuts)

Instructions:

Step 1: Prepare the Blueberry Filling

1. Preheat your oven to 350°F (175°C).
2. In a large mixing bowl, combine the blueberries, sugar, cornstarch, lemon juice, vanilla, and salt. Stir gently to mix everything together. If you’re using frozen blueberries, there’s no need to thaw them.
3. Transfer the mixture into a greased 9-inch baking dish and spread it evenly. Set aside while you prepare the crumble topping.

Step 2: Make the Crumble Topping

1. In a separate bowl, combine the oats, flour, brown sugar, cinnamon, and salt. Stir the dry ingredients together.
2. Add the cold butter cubes into the dry mixture. Using a pastry cutter, two knives, or your fingers, cut the butter into the dry ingredients until the mixture forms a crumbly texture with pea-sized pieces of butter throughout.
3. If you’re adding nuts, mix them in with the crumble topping.

Step 3: Assemble the Crumble

1. Evenly distribute the crumble topping over the blueberry mixture in your baking dish. Make sure it covers the filling entirely.

Step 4: Bake the Crumble

1. Place the baking dish in the oven and bake for 40-45 minutes, or until the topping is golden brown and the filling is bubbling.
2. If the topping is browning too quickly, you can loosely cover the dish with foil for the last 10-15 minutes of baking.

Step 5: Cool and Serve

1. Let the crumble cool for about 10 minutes before serving. This allows the filling to set and makes it easier to serve.
2. Serve warm with a scoop of vanilla ice cream, whipped cream, or Greek yogurt for a perfect treat.

Storage & Make-Ahead Tips:

• Storage: Store any leftover crumble in an airtight container in the refrigerator for up to 3-4 days.
• Freezing: Allow the crumble to cool completely, then wrap tightly with plastic wrap and freeze for up to 3 months. When ready to enjoy, bake it from frozen at 350°F for about 30-40 minutes or until warmed through.

Variations:

• Mixed Berry Crumble: Swap out the blueberries for a mix of strawberries, raspberries, and blackberries.
• Apple Blueberry Crumble: Add a cup of chopped apples to the filling for extra texture and flavor.
• Nutritional Adjustments: You can use almond flour or coconut flour for a gluten-free option, and stevia or monk fruit sweetener for a lower-sugar version.
