Ingredients
For the Filling:
- 2 to 2 1/4 pounds (about 36 oz) fresh blueberries, rinsed and well-drained
- 2 tablespoons freshly squeezed lemon juice
- 1 teaspoon lemon zest (zest of 1 lemon)
- 3 tablespoons all-purpose flour
- 1/4 cup granulated sugar
- 1 teaspoon ground cinnamon
For the Crumble Topping:
- 1 cup all-purpose flour
- 1/4 cup granulated sugar
- 1/3 cup brown sugar, packed
- 1/8 teaspoon salt
- 8 tablespoons (1 stick) cold, unsalted butter, diced
- 1/2 cup quick-cooking oats
- 1 cup sliced almonds, divided
To Serve:
- Vanilla ice cream or whipped cream (optional)
Instructions:
- Preheat your oven to 350˚F (175˚C).
- In a large mixing bowl, toss the blueberries with 2 tablespoons of lemon juice and 1 teaspoon of lemon zest. Set them aside.
- In a separate small bowl, whisk together the granulated sugar, flour, and ground cinnamon. Toss the mixture with the blueberries until the fruit is evenly coated. Pour the blueberry mixture into a 9×13-inch baking dish.
- In a food processor fitted with a steel blade, combine the flour, granulated sugar, brown sugar, and salt. Pulse a few times to combine. Add the cold diced butter and pulse until the mixture resembles coarse crumbs with pea-sized butter pieces.
- Transfer the crumble mixture to a bowl, and add the oats. Use your hands to mix until large crumbles form. Stir in ½ cup of the sliced almonds.
- Evenly spread the crumble topping over the blueberries, then sprinkle the remaining sliced almonds on top.
- Bake for 40 minutes or until the topping is golden brown and the blueberries are bubbling at the edges.
- Remove from the oven and let the crumble cool for at least 15 minutes before serving. This allows it to thicken slightly. It will stay warm for a couple of hours and can be reheated the next day.
