Method
Start with the Right Blueberries
- Go with fresh blueberries if they’re in season. They’re firm, bright, and burst with natural flavor. Frozen berries work too, but make sure you thaw and drain them well. Excess water is the enemy of clean pie slices.
Mix the Filling with Care
- In a large bowl, gently toss the blueberries with sugar, cornstarch, lemon juice, zest, cinnamon, and salt. Stir just enough to coat everything evenly, but don’t mash the berries.
- The cornstarch is your best friend here — it thickens the juices just right so the pie stays firm.
- Let the mixture sit for about 10 minutes while you prep the crust. This helps the berries release a bit of juice and lets the cornstarch begin its magic.
Build Your Pie
- Roll out your bottom crust and fit it into a 9-inch pie plate. Let the edges hang over slightly. Spoon the blueberry mixture into the crust and dot the top with those little bits of butter. That small touch adds richness you don’t want to skip.
- Now, top it with your second crust. You can go with a full cover and cut slits to vent, or make a lattice if you’re feeling fancy. Either way, press and crimp the edges to seal.
- Brush the top with the beaten egg and sprinkle with coarse sugar if you want a golden, sparkly finish.
Bake It Right
- Preheat your oven to 400°F (200°C). Place the pie on a baking sheet — this helps catch any bubbling juice that tries to escape. Bake for 20 minutes at this high temp to set the crust.
- Then, reduce the heat to 350°F (175°C) and bake for another 35–40 minutes. If the edges brown too fast, cover them with foil or a pie shield. The pie is ready when the crust is golden and the filling bubbles thickly through the vents.
The Hardest Part: Letting It Cool
- This step is non-negotiable. Let the pie cool for at least 4 hours at room temperature. That’s how you get a filling that stays put when sliced. Cut into it too early and all bets are off.
- If you’re serving it later, once cooled, you can store it at room temp for a day or refrigerate it for up to 4. Warm it slightly before serving if you like it a little gooey.
