Ingredients

2 store-bought pie crusts
2 1/2 cups raspberries (fresh or frozen(thawed))
2 1/2 cups blackberries (fresh or frozen(thawed))
2 cups blueberries (fresh or frozen(thawed))
1 T. lemon juice
1/3 cup cornstarch
1 1/2 cups granulated sugar
2 T. unsalted butter (cut into small pieces)
1 large egg

Instructions

Preheat your oven to 400°F (200°C). Place one pie crust into a 9-inch pie plate, pressing it gently into the bottom and sides.
In a large mixing bowl, combine the raspberries, blackberries, and blueberries. Gently fold in the lemon juice.
In a small bowl, whisk together the cornstarch and granulated sugar. Sprinkle this sugar mixture over the berries and fold gently until evenly coated. Be careful not to crush the berries.
Pour the berry filling into the prepared bottom crust. Dot the top of the filling evenly with the pieces of unsalted butter.
Place the second pie crust over the filling. You can create a full top crust, a lattice, or cut decorative vents. Crimp the edges to seal the two crusts together.
In a small bowl, beat the egg with one tablespoon of water to create an egg wash. Lightly brush the top crust with the egg wash.
Place the pie on a baking sheet (to catch any drips) and bake for 20 minutes. Then, reduce the oven temperature to 350°F (175°C) and continue baking for 45-50 minutes, or until the crust is deep golden brown and the filling is bubbly.
Remove the pie from the oven and let it cool completely on a wire rack for at least 3-4 hours before slicing. This allows the filling to set properly.

Variations

Crumb Topping: Skip the top pie crust. Instead, combine 1 cup flour, 1/2 cup brown sugar, and 1/2 cup cold cubed butter into coarse crumbs. Sprinkle over the filling before baking.
Mini Pies: Use the same method to create individual hand pies or small tartlets using a muffin tin for a portable treat.
Serve à la Mode: Transform each slice by serving it warm with a scoop of vanilla ice cream for a classic combination.
Galette Style: For a rustic look, roll one crust into a large circle, pile the filling in the center, and fold the edges over the berries, leaving the center exposed.

Tips for Success

Let frozen berries thaw completely and drain any excess liquid to prevent a soggy crust.
Always place your pie on a baking sheet lined with foil or parchment paper to catch any bubbling juices that overflow.
For a beautifully golden crust, avoid over-brushing the egg wash; a light, even coat is sufficient.
The most crucial step is allowing the pie to cool completely. Slicing too early will result in a runny filling.

Storage & Reheating

Store leftover pie, covered loosely at room temperature, for up to 2 days, or refrigerated for up to 5 days. To reheat, warm individual slices in a 300°F (150°C) oven for about 10 minutes to revive the crust’s flakiness.

FAQ

Can I use all frozen berries?

Yes, you can use all frozen berries. Ensure they are completely thawed and well-drained to avoid excess moisture in your filling.

My pie crust is browning too fast. What should I do?

If the edges or top are browning too quickly, loosely tent the pie with aluminum foil for the remaining bake time.

Why is my filling runny?

This is usually due to slicing the pie before it has cooled completely. The cornstarch needs several hours to fully set as the pie cools.

Can I make this pie ahead of time?

Absolutely. You can assemble the pie, cover it tightly, and refrigerate it overnight before baking. You may need to add a few extra minutes to the bake time.

Do I need to adjust anything if using only fresh berries?

No, the recipe works perfectly with fresh berries. You may find the filling sets a bit faster as fresh berries typically release less liquid than frozen.

What’s the purpose of the egg wash?

The egg wash gives the crust a beautiful, shiny, golden-brown finish and helps it achieve a crisp texture.
