This old-fashioned Blueberry Crumble recipe is easy to make with fresh or frozen berries and features a scrumptious oat and almond crumble topping. It's ready to serve in under an hour, and perfect to enjoy warm with a scoop of vanilla ice cream!
Preheat the oven to 375°F. Set out a 2-quart baking dish: a deep 8 x 8-inch square, a 9 x 9-inch square, or 2-quart round dish are great options!
Prepare the Blueberry Filing: In a large mixing bowl, combine the blueberries, sugar, lemon juice, lemon zest, cornstarch, and salt. Mix well to combine. Pour the blueberry mixture into the baking dish. *If your baking dish is deep enough, you can mix these ingredients right in the dish to reduce clean up.
For the Crisp Topping: Set out a medium mixing bowl. Combine the flour, oats, light brown sugar, butter cubes, cinnamon, and salt. Either use a pastry blender tool, or your hands, to mix the ingredients together until the butter is broken into small pea-sized pieces. Then mix in the sliced almond, if using.
Sprinkle the crumble topping over the blueberries in the pan. Place the blueberry crisp in the oven and bake for approximately 35- 40 minutes, until the crisp topping is golden brown and the blueberries are bubbling around the edges.
Allow the blueberry crisp to cool for at least 5-10 minutes. Then scoop and serve with vanilla ice cream.

Notes
Let the crisp cool before transferring to an airtight container. Blueberry crumble will keep well in the fridge for up to 3-4 days.Crisps can be frozen before or after baking. Make them in foil pans to give away as edible gifts! If baking from frozen, increase the bake-time to 50-60 minutes.
