9-Inch Blueberry Pie Recipe: Flaky Crust and Bursting Fruit Filling

This 9-inch blueberry pie recipe delivers the perfect balance of a flaky crust and a juicy, spiced filling that bakes up with golden perfection. 💛 The secret lies in a tender, buttery crust that holds its shape while encasing blueberries that burst with every bite—no soggy bottoms here.

I’ve tested this recipe countless times to ensure it’s foolproof, whether you’re using store-bought dough or rolling out your own from scratch.

The filling is where the magic happens: a mix of fresh or frozen blueberries, cornstarch for thickness, and just the right amount of sugar to caramelize without overpowering the fruit’s natural sweetness.

A pinch of cinnamon and lemon zest brightens the flavors, while a lattice crust (optional) adds that classic piehouse appeal. Baking at the right temperature ensures the crust stays crisp while the filling sets just enough to hold its shape.

By the time it emerges from the oven, you’ll have a pie with a golden, flaky crust that’s tender but sturdy, and a filling so luscious it practically oozes with juicy blueberries.

The aroma alone will have everyone gathering around the table. Serve it warm with a scoop of vanilla ice cream or a dollop of whipped cream for the full experience.

This recipe scales perfectly for gatherings or meal prep—just adjust the baking time if making a larger pie. The instructions are clear, the steps are simple, and the result? A showstopper dessert that tastes like summer in every slice. Let’s get baking!

Ingredients for 9 inch blueberry pie

Few ingredients, maximum flavor—this pie delivers that perfect flaky crust and juicy blueberry filling.

The butter is non-negotiable here. Use cold, cubed butter—no melting—so you get that signature flaky texture. I grab Land O’Lakes unsalted from the store, but any quality brand works. For the blueberries, fresh is ideal but frozen works too—just don’t thaw them first. The cornstarch is your secret weapon for that glossy, thick filling that holds its shape. Bob’s Red Mill is my go-to brand, but any pure cornstarch will do.

No cornstarch? Arrowroot powder at the same amount works in a pinch. Fresh blueberries too pricey? Frozen wild blueberries add extra flavor. The lemon zest can be substituted with 1 tsp bottled lemon juice if you’re in a rush, though fresh zest brightens the filling beautifully. For the crust, if you’re short on butter, shortening works too—just know it’ll be slightly less flaky. And if you’re making a lattice, that 0.25 cup heavy cream brushes on the strips for that golden finish.

Store any leftover crust dough in the fridge for 3 days or freeze for 3 months. The filled pie keeps at room temperature for 2 days or refrigerated for 5 days. For best texture, reheat slices in a 350°F oven for 5-10 minutes. The filling reheats beautifully, so leftovers taste just as good as day one. I always make a double batch—one for today, one for tomorrow’s dessert.

Step-by-step instructions for 9-Inch blueberry pie

Here's how to build a pie with a perfect flaky crust and juicy blueberry filling.

In a large bowl, combine the 2.25 cups all-purpose flour and 0.5 teaspoon kosher salt. Cut in the 1 cup cold unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This ensures maximum flakiness when baked.

Gradually add the 0.33 cup ice water, one tablespoon at a time, mixing gently with a fork until the dough just comes together. The dough should hold when pressed but not be sticky. Divide it into two equal discs, wrap each in plastic wrap, and refrigerate for at least 1 hour. Cold dough prevents shrinking and ensures a crisp crust.

In a large bowl, gently toss the 4 cups fresh blueberries with the 0.75 cup granulated sugar, 2 tablespoons cornstarch, 1.5 teaspoons ground cinnamon, and 1 tablespoon lemon zest. This combination prevents the berries from sinking and creates a glossy, thick filling. Let the mixture sit for 15 minutes to allow the juices to develop.

Transfer the blueberry mixture to a medium saucepan and cook over medium heat for 5-7 minutes, stirring frequently, until the berries soften slightly and the filling thickens. You'll know it's ready when it coats the back of a spoon. Remove from heat and let it cool completely before filling the pie.

Preheat your oven to 375°F. On a lightly floured surface, roll out one of the chilled dough discs into a 12-inch circle (about 1/8-inch thick). Transfer it to a 9-inch pie dish, gently pressing it into the bottom and up the sides. Trim any excess dough hanging over the edge.

Pour the cooled blueberry filling into the prepared crust, mounding it slightly in the center. Roll out the second dough disc and cut it into strips for a lattice top. Arrange the strips in a crisscross pattern, leaving the center open for steam to escape. Brush the lattice with the 0.25 cup heavy cream for a golden finish.

Place the pie on a baking sheet to catch any drips and bake for 45-50 minutes until the crust is deep golden brown and the filling bubbles gently. The edges should be crisp, and the center should be set but still slightly jiggly.

Remove the pie from the oven and let it cool on a wire rack for at least 2 hours before serving. This resting period allows the filling to thicken and the crust to firm up. Serve warm with 1.5 cups vanilla ice cream for the perfect balance of sweet and tart.

Pro cooking tips for 9 inch blueberry pie

Butter Temperature Matters

The key to a flaky crust starts with cold butter—I mean cold. Cut your 1 cup unsalted butter into ½-inch cubes and let them sit in the freezer for 10 minutes before mixing with flour.

This prevents melting during the dough process, which creates those signature flaky layers. I’ve ruined crusts too many times by using butter that was even slightly warm—don’t make my mistake! 🧈

Prevent the Soggy Bottom

No one likes a soggy pie crust, and the secret is pre-baking the bottom crust for 5-7 minutes before adding the filling. This creates a barrier that keeps the juicy blueberries from turning the crust mushy.

For extra insurance, sprinkle a thin layer of dry cornstarch (about 1 tbsp) over the pre-baked crust before adding the filling. It’s a trick I picked up from my grandmother, and it works every time. ⏰

Lattice Perfection

If you’re making a lattice top, brush the strips with heavy cream after arranging them in the crisscross pattern. This adds a golden sheen and prevents the dough from drying out. For a cleaner look, use a pizza wheel to cut the strips—it gives you straight, even edges every time.

I like to leave the center open so the filling can bubble up beautifully. 💫

Blueberry Prep Trick

Toss your 4 cups blueberries with 1 tbsp lemon juice before mixing with sugar and cornstarch. This brightens their natural flavor and prevents them from turning mushy during baking.

For frozen berries, I like to pat them completely dry with paper towels first—this keeps the filling thicker and prevents a watery mess. 🫐

Oven Rack Placement

Place your pie on the middle rack of your oven, not the top. The middle rack ensures even heat distribution, so the crust bakes evenly without burning. If your oven runs hot, consider lowering the temperature to 350°F for the last 10 minutes of baking to avoid over-browning.

A light-colored baking sheet underneath catches drips and makes cleanup easier. 🔥

Resting is Non-Negotiable

Let your pie cool for at least 2 hours before slicing—this allows the filling to set properly and the crust to firm up. I know it’s tempting to dig in right away, but rushing leads to a runny filling and a crumbly crust.

If you’re in a hurry, chill the pie in the fridge for 30 minutes to speed up the process. Patience pays off! ⏳
