Preheat oven to 400 degrees F.

Press one pie crust into a 9-inch glass pie dish, ensuring it fits snugly.

In a large bowl, combine sugar, flour, cinnamon, and nutmeg.

Add blueberries to the bowl and toss to coat them with the dry mixture.

Pour the blueberry mixture into the prepared pie crust.

Spread the berry mixture evenly within the pie dish.

Cover the pie with the second pie crust.

Fold the edges of the top and bottom crusts together to create a seal.

Crimp the edges of the crust using your fingers or a fork.

Cut a few slits in the top crust to allow steam to escape.

Bake for 40 minutes, or until the crust is golden brown.

If the edges brown too quickly, cover them with a pie shield or aluminum foil after 20 minutes.

Let the pie cool completely to room temperature before serving.
