A juicy blueberry pie with a golden, buttery crust showcases summer berries at their peak. This family-favorite dessert is a gorgeous celebration of fresh fruit baking.
Preheat your oven to 425°F, ensuring the rack is placed in the lower third for proper crust browning.
In a large bowl, gently toss fresh blueberries with granulated sugar, flour, salt, lemon zest, and vanilla extract until evenly coated.
Roll out the bottom pie crust and fit it carefully into a 9-inch pie pan, pressing gently to avoid tearing.
Pour the blueberry mixture into the crust and dot evenly with unsalted butter to help moisture balance during baking.
Cover with the top crust, crimp edges tightly, and cut several slits for steam escape; brush the surface with beaten egg for a golden finish.
Bake at 425°F for 20 minutes, then reduce heat to 350°F and bake for an additional 35 minutes until the filling bubbles and crust is deep golden brown.
Cool the baked pie on a wire rack for at least 2 hours to set the filling before slicing.
