Step by Step Picture Instructions
Start by preheating your oven to 350 degrees. Also prep a 9×9 baking dish with non- stick spray.
In a large bowl stir together the blueberries, cornstarch, sugar, kosher salt, lemon zest and lemon juice.
Now mix together your crumble topping ingredients – flour, oats, brown sugar, pecans, cinnamon and salt.
Cut the butter into the oat mixture with a pastry cutter, two forks, two knives, or just your clean hands, until you have a coarse crumbly mixture.
Pro Tip: This is a great video showing how to cut butter into flour.
Pour the blueberries into the prepared baking dish, top with the flour/oat mixture.
Pro Tip: if your 9×9 pan is shallow and the filling almost goes to the top, place it on a rimmed baking sheet so your berries don’t spill over into your oven.
Bake for 40 minutes.
Let the Blueberry Crumble cool for about 20 minutes and then you can serve it topped with ice cream or sweetened whipped cream.
You can also make this recipe with frozen blueberries, although there may be a bit more liquid than with fresh.
