Blueberry Pie Recipe Using Frozen Blueberries: Bursting Berry Flavor in a Flaky Crust

This pie delivers bursting berry flavor and a flaky crust every time, even with frozen blueberries.

I’ve tested this method repeatedly to ensure the filling sets perfectly without a soggy bottom. The key is proper thawing and a thickener that handles the extra moisture.

Ingredients for Blueberry Pie Recipe Using Frozen Blueberries

Frozen blueberries, pantry staples, and a few fresh touches create this classic pie with ease.

The blueberries are key here. Wild frozen blueberries from Trader Joe’s or Wyman’s have the best flavor and hold their shape. Thaw them completely and drain well—this prevents a watery filling. The cornstarch is non-negotiable for thickening, but instant tapioca works too if that’s what you have. For the crust, European-style butter like Plugrá has higher fat content for extra flakiness.

No fresh lemon? Bottled lemon juice at equal amount works in a pinch, but zest is harder to substitute—skip it if you must. Out of cornstarch? All-purpose flour at twice the amount can stand in, though the filling will be slightly less glossy. Brown sugar can be replaced with all granulated, but you’ll lose some caramel notes. The egg wash is optional but gives that golden professional finish.

Assemble the pie just before baking for best results. Leftovers keep 3-4 days at room temperature, though the crust softens over time. Freeze for up to 3 months—reheat in a 350°F oven to crisp the crust.

Step-by-Step Instructions for Blueberry Pie with Frozen Blueberries

Master these techniques for a flaky crust and perfectly thickened filling every time.

Step 1: Prepare the Flaky Pie Crust

In a large bowl, combine 2.5 cups all-purpose flour and 0.25 tsp salt. Cut in 1 cup cold unsalted butter (cubed) using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces visible. This visible butter creates the flaky layers.

Gradually add 0.5 cup ice water, 1 tablespoon at a time, mixing just until the dough comes together. Overworking develops gluten, which makes the crust tough. Divide the dough into two equal portions, shape into discs, wrap in plastic, and refrigerate for 1 hour. Chilling relaxes the gluten and firms the butter for easier rolling.

Step 2: Make the Blueberry Filling

In a large bowl, gently fold together the 6 cups thawed and drained frozen blueberries, 0.75 cup granulated sugar, 0.25 cup light brown sugar, 0.25 cup cornstarch, 2 tbsp lemon juice, 1 tsp lemon zest, and 0.25 tsp ground cinnamon. The cornstarch needs to coat all the berries evenly to prevent clumping during baking.

Let the mixture sit for 15-20 minutes while you roll out the crust. You’ll notice the berries release some liquid—that’s normal. The cornstarch will absorb this excess moisture as it bakes, creating that perfect thick filling that doesn’t run when sliced.

Step 3: Assemble and Crimp the Pie

On a lightly floured surface, roll one dough disc into a 12-inch circle. Transfer to a 9-inch pie dish, pressing gently into the bottom and up the sides. Trim the edges, leaving a ½-inch overhang. Add the blueberry filling, mounding slightly in the center. The filling should look abundant—it reduces slightly during baking.

Roll the second dough disc and place it over the filling. Trim to ½-inch overhang, then fold the top crust edges under the bottom crust and crimp decoratively. Brush the top with a mixture of 1 whole large egg and 1 tsp vanilla extract for a golden finish. Cut 4-5 slits in the center to allow steam to escape.

Step 4: Bake to Golden Perfection

Preheat oven to 375°F. Place the pie on a baking sheet (to catch drips) and bake for 50-60 minutes, until the crust is deep golden brown and the filling bubbles visibly through the vents. The bubbles indicate the cornstarch has activated and thickened the juices.

If the edges brown too quickly, cover them with a pie shield or foil. Rotate the pie halfway through baking for even browning. The pie is done when the crust is uniformly golden and the center filling bubbles thickly, not runny. Cool on a wire rack for at least 2 hours before slicing—this allows the filling to set completely.

Best Sauces and Condiments for This Recipe

Spicy Options

For those who love a little heat, a drizzle of Sriracha-infused honey can add a surprising yet delightful kick. The sweetness of the honey balances the spice, complementing the tartness of the blueberries. If you prefer store-bought, Sweet Heat Chili Sauce is a great choice. For a homemade twist, mix a teaspoon of chili powder into a cup of warm honey and let it infuse for 10 minutes.

Sweet and Tangy

A classic pairing for blueberry pie is a vanilla ice cream topping, but for something a bit more unique, try a lemon curd sauce. The zesty lemon cuts through the richness of the pie, offering a refreshing contrast. Store-bought Stonewall Kitchen Lemon Curd works perfectly, or you can make your own by whisking lemon juice, sugar, eggs, and butter over low heat until thickened.

Creamy Delights

Whipped cream is a staple, but for an extra indulgent experience, opt for a cinnamon-spiced whipped cream. Simply fold a pinch of cinnamon into freshly whipped cream. Alternatively, a dollop of crème fraîche adds a tangy depth that pairs wonderfully with the pie’s sweetness. Both options are easy to make at home or find in most grocery stores.
