Blueberry Pie

Few desserts say American summer quite like a blueberry pie cooling on the windowsill. Blueberries are one of the few fruits native to North America, long gathered wild across the Northeast and Upper Midwest before cultivation began in earnest in the early twentieth century, and their peak in July has made blueberry pie a fixture of Independence Day tables and county fairs alike. This version keeps the filling pure and bright: four cups of berries thickened with cornstarch, lifted with lemon zest and juice, and warmed with a whisper of cinnamon, all tucked between two flaky crusts and brushed with egg wash for a burnished, golden finish. The trick to a sliceable pie rather than a soupy one is patience — both in measuring the thickener and in letting the baked pie cool completely so the filling can set. Serve it just warm or at room temperature with a scoop of vanilla ice cream, and you have the taste of summer in a single slice.
Ingredients
Serves 8Instructions
- 1
Preheat oven to 375°F (190°C).
- 2
Line a 9-inch pie plate with one of the pie crusts.
- 3
In a large bowl, toss blueberries with sugar, cornstarch, lemon zest, lemon juice, and cinnamon.
- 4
Transfer filling into the pie shell and dot with cubed butter.
- 5
Top with the second pie crust. Place it whole and cut slits, or create a lattice top. Crimp edges to seal.
- 6
Brush the top crust with beaten egg.
- 7
Bake for 50 minutes, or until the crust is golden brown and the filling is bubbling. If crust browns too quickly, cover edges with foil.
- 8
Cool on a wire rack for at least 3 hours to allow filling to set before slicing.
Chef's Tips
- ✦ Toss the berries thoroughly with the sugar and cornstarch so the thickener coats evenly — clumps of dry starch lead to pockets of runny filling.
- ✦ Cut generous vents or a lattice in the top crust so steam escapes and the filling can bubble and thicken rather than steam the crust soggy.
- ✦ Bake on a rimmed sheet pan and look for the filling to bubble visibly in the center — that bubbling is what activates the starch and sets the pie.
- ✦ Let the pie cool completely, at least 4 hours, before slicing; cutting it warm releases a flood of filling that will not set back up.
Ingredient Substitutions
-
fresh blueberries → frozen blueberries
Use straight from frozen without thawing and add 1 to 2 extra tablespoons of cornstarch, since frozen berries release more liquid.
-
cornstarch → quick-cooking tapioca or all-purpose flour
Use roughly equal tapioca, or double the volume if substituting flour; tapioca gives the clearest, glossiest filling.
-
granulated sugar → reduce to 1/2 cup, or use light brown sugar
Cut the sugar for very sweet berries; brown sugar adds a subtle caramel note.
-
store-bought pie crusts → homemade all-butter double crust
A from-scratch butter crust bakes up flakier and more flavorful if you have time to chill it well.

Frequently Asked Questions
Can I use frozen blueberries for blueberry pie? ▼
Yes. Use them straight from the freezer without thawing to limit excess liquid, and add 1 to 2 extra tablespoons of cornstarch since frozen berries give off more juice. The bake may take a few minutes longer.
Why is my blueberry pie runny, and how do I thicken it? ▼
A runny pie usually means too little thickener or not enough cooling time. Make sure the filling bubbles in the center during baking to activate the cornstarch, and let the pie cool completely — at least 4 hours — so the filling sets before you slice it.
How long should blueberry pie cool before cutting? ▼
Cool it at least 4 hours at room temperature, or until the bottom of the pan is no longer warm. The filling thickens as it cools; slicing too early releases liquid that will not set back up.
Can I make blueberry pie ahead or freeze it? ▼
Baked blueberry pie keeps 2 days at room temperature or up to 4 days refrigerated. You can also freeze it baked and cooled, well wrapped, for up to 3 months — thaw overnight and warm in a low oven to re-crisp the crust.
