Ingredients

For the Blueberry Filling

  • 500 g fresh blueberries
  • 2 tablespoon granulated sugar
  • 2 tablespoon all-purpose flour
  • 1 tablespoon lemon juice
  • ⅛  teaspoon salt

For the Crumble Topping

  • 180 g all-purpose flour
  • 100 g granulated sugar
  • 100 g melted butter
  • ⅛  teaspoon salt
  • ½ teaspoon cinnamon

Instructions

  • Preheat the oven to 375°F / 190°C (338°F convection / 170°C fan). Lightly grease an 8-inch or 9-inch baking dish. 
  • In a large bowl, combine the blueberries, sugar, flour, lemon juice, and salt. Gently stir until the berries are fully coated, and everything looks evenly mixed. Pour the blueberry mixture into the prepared baking dish, spreading it out into an even layer.
  • In a separate bowl, mix together the flour, sugar, salt, and cinnamon for the topping. Add the melted butter to the dry ingredients and stir until the mixture turns into soft, crumbly clumps.
  • Spread the crumble topping evenly over the blueberry filling, making sure to cover all the fruit without pressing it down.
  • Place the dish in the center of the oven and bake for 35–40 minutes, or until the topping is golden brown and the blueberry filling is bubbling around the edges.
  • Remove from the oven and let it cool for 10–15 minutes before serving so the filling can set slightly.

Notes

Use Frozen Blueberries If Needed: I’ve made this with frozen berries when fresh ones weren’t available, just thaw them first and drain off the extra liquid.
Don’t Press the Topping Down: Leaving the crumble loose creates a crisp, golden top that contrasts beautifully with the soft fruit underneath.
Let It Rest before Serving: Giving it 10–15 minutes out of the oven helps the filling thicken slightly and makes it easier to serve.
Reheat Leftovers in the Oven: I prefer warming it up in the oven rather than the microwave to keep the topping crisp.
