Strain the juice from the blueberries and reserve 2 Tbsp to go in the pie.
Transfer the blueberries to a medium bowl.
Preheat Oven
Preheat oven to 400℉.
Place a sheet of aluminum foil on the bottom rack, directly under where you will be placing the pie.
Prepare The Crust
The crust must sit at room temperature for 15-20 minutes or as directed on the package.
Place the bottom crust in the pie plate.
Dry Ingredients
In small bowl whisk together the sugars, cornstarch (or flour), and cinnamon.
Mix
Pour the dry ingredients over the blueberries and stir well. Stir in the reserved blueberry juice while blending the mixture.
Stir gently, trying to not crush or break any of the blueberries.
Assemble The Pie
Pour or scoop the filling into the crust.
Add top crust and crimp the edges to create a scalloped look.
Cut at least four slits around the top of the crust to allow the filling to vent while baking.
Bake
Place the pie on the middle rack, directly over the sheet of aluminum foil that should be on the bottom rack.
Bake for 40-45 minutes.
Pie is done when crust is golden brown and filling starts to bubble.
Cool
Place on wire cooling rack and allow to sit at room temperature for at least 3 hours.
