This Triple Berry Pie is a vibrant, fruity dessert perfect for any occasion. Sweet, juicy berries nestled in a buttery homemade crust with a golden lattice top make for a show-stopping pie that’s as delicious as it looks.

Ingredients
Pie Crust:
- Homemade pie crust for a 9-inch deep-dish pan (makes 2 crusts: one bottom, one top)
Filling:
- 7 cups fresh or frozen berries (raspberries, blueberries, blackberries — about 2 1/3 cups of each)
- 1 cup granulated sugar (plus extra for sprinkling on top)
- 1 Tbsp lemon juice
- 4 Tbsp cornstarch
- 2 Tbsp butter
Topping:
- 1 large egg white, beaten
Instructions
1. Cook the Berries
In a large saucepan, combine the berries, sugar, and lemon juice. Heat over medium until the berries are warm and juicy, about 5–10 minutes, stirring gently. Taste and adjust sweetness if desired (add up to ¼ cup more sugar for a sweeter pie).
2. Thicken the Filling
Spoon out about ½ cup of the berry juice into a small bowl. Whisk the cornstarch into the juice until smooth. Return the pot to a gentle simmer and slowly pour in the cornstarch mixture, stirring carefully to avoid crushing the berries. Cook until thickened, about 2–5 minutes.
3. Add Butter and Cool
Remove the pan from heat, stir in the butter, and allow the mixture to cool for 15 minutes.
4. Assemble the Pie
Pour the berry filling into the unbaked bottom pie crust.
- Lattice Top (optional): Roll out the top crust into a circle slightly larger than the pie pan. Cut strips with a pizza cutter. Lay the longest strip across the center, then add parallel strips on either side. Weave a lattice by folding back alternating strips and laying perpendicular strips, then unfold. Repeat until the pie is covered. Trim any overhanging dough and pinch the edges together with the bottom crust.
Brush the top crust with beaten egg white and lightly sprinkle with sugar.
5. Bake
Preheat the oven to 400°F (200°C). Bake for 40–45 minutes, checking after 25 minutes. If the crust is browning too quickly, cover loosely with foil.
6. Cool and Serve
Transfer to a wire rack and allow to cool completely for several hours. Slice once cooled, or cover and refrigerate overnight for next-day serving.
