Instructions
Gather all ingredients. Set an oven rack to the lowest position and preheat the oven to 375°F (190°C).
Mix sugar, cornstarch, cinnamon, and salt together in a bowl; sprinkle over blueberries.
Line a pie dish with one pie crust. Pour berry mixture into the crust and dot with butter. Cut remaining pastry into 1/2- to 3/4-inch-wide strips. Use the strips to weave a lattice top. Crimp and flute the edges.
Bake pie on the lowest oven rack until filling is bubbling and crust is golden brown, about 50 minutes.
