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

This 9-inch blueberry pie recipe delivers a perfect balance of flaky lattice crust and juicy, bursting blueberry filling that tastes like summer in every bite. The secret lies in pre-cooking the fruit to prevent a soggy bottom while keeping the filling thick and vibrant.

I've baked this pie countless times for family gatherings, and it never fails to disappear faster than the plates hit the table.

What sets this recipe apart is the lattice crust—elegant yet simple to create—with its signature diamond pattern that allows steam to escape while keeping the filling tender.

The crust itself is made with a simple pie dough that's rolled out just thick enough to hold its shape during baking, yet still crisp up beautifully.

The filling combines fresh blueberries with a touch of lemon juice for brightness, cornstarch for thickening, and just the right amount of sugar to enhance their natural sweetness.

By the time it emerges from the oven, you'll have a pie with a golden, shimmering crust and filling that's thick enough to hold its shape when sliced, yet still juicy enough to make your mouth water.

The aroma alone will have everyone gathering in the kitchen, and the first bite delivers that perfect combination of flaky crust and sweet-tart blueberry goodness. This is the kind of pie that makes you feel like you've earned your dessert.

The best part? This recipe scales beautifully for holidays or potlucks, and the leftovers—if there are any—are even better the next day when the flavors have had time to meld.

Whether you're a seasoned baker or just starting out, this blueberry pie delivers restaurant-quality results with simple techniques and a foolproof method.

Ingredients for 9 inch blueberry pie

These 12 simple ingredients create a showstopping pie that'll disappear faster than you can slice it.

Blueberries are the star—pick the freshest, firmest berries you can find. Local farmers markets or grocery store pre-washed packs work great. If using frozen, thaw and drain them completely to avoid a watery filling. The sugar amount balances sweetness perfectly, but adjust to taste if your berries are extra tart. For that restaurant-quality touch, King Arthur Flour or Bob's Red Mill all-purpose flour makes the crust extra tender. And trust me on the cornstarch—it's what keeps that filling thick and glossy without being gluey.

No cornstarch? Arrowroot powder works 1:1, but cornstarch gives that classic pie filling texture. Short on butter? Coconut oil works too, though it adds a slight coconut flavor. The lattice crust is where the magic happens—cut the dough strips just under 1/2-inch wide for those perfect diamond patterns. For extra flakiness, chill your dough for at least 1 hour before rolling. And if you're feeling fancy, brush the finished lattice with heavy cream before baking for that golden sheen.

This pie tastes even better the next day—store leftovers covered at room temperature for up to 2 days. For longer storage, wrap tightly and freeze for up to 3 months. The lattice crust stays crisp for about 24 hours, so serve it fresh if you can. Pro tip: Bake the filling ahead and refrigerate it overnight—it thickens beautifully and tastes more developed. And if you're making this for a crowd, double the recipe—two 9-inch pies disappear just as fast as one!

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

Here's how to create that perfect balance of juicy blueberries and flaky lattice crust.

In a large bowl, combine the 4 cups fresh blueberries, 1.5 cups granulated sugar, 0.25 cup all-purpose flour, and 2 tbsp cornstarch. Gently toss until the sugar and flour evenly coat the berries—this prevents a gummy filling. The sugar will begin to dissolve slightly, creating a syrupy base.

Transfer the mixture to a 9-inch pie dish and spread it evenly. Pour the 2 tbsp lemon juice over the top and gently stir to distribute. The acidity brightens the blueberries and helps thicken the filling. Don't skip this step—it makes all the difference in texture and flavor.

In a food processor, pulse the 0.75 cup cold unsalted butter until it resembles coarse crumbs. Add the 2.5 cups all-purpose flour and 0.5 tsp salt, then pulse until the mixture resembles coarse meal with pea-sized butter pieces. With the processor running, slowly add the 0.5 cup ice water until the dough just comes together.

Turn the dough onto a lightly floured surface and divide it into two equal discs. Wrap each in plastic wrap and refrigerate for at least 1 hour. Chilling is crucial—it prevents the butter from melting during rolling and ensures a flaky crust. If you're in a hurry, chill for 30 minutes in the freezer instead.

Roll out one disc of dough to fit your 9-inch pie dish, leaving a 1-inch overhang on all sides. Gently drape it over the dish, then trim the excess. Roll out the second disc for the lattice top—cut it into 1-inch strips using a pizza cutter or sharp knife. Press the rolled-out dough into the pie dish, crimping the edges to seal.

Arrange the lattice strips in a herringbone pattern, alternating directions with each row. Brush the top with a mixture of the 1 whole large egg beaten with 1 tbsp granulated sugar and 1 tbsp heavy cream (if using). This creates a golden, glossy finish and adds sweetness. Preheat your oven to 375°F while the lattice sets for 5 minutes—this prevents it from sticking.

Bake the pie for 45-50 minutes until the crust is deep golden brown and the filling bubbles gently at the edges. If the lattice starts browning too quickly, loosely cover it with aluminum foil. The filling should be thickened but still slightly jiggly in the center—it will set as it cools.

Let the pie cool completely on a wire rack for at least 2 hours before slicing. This resting time allows the filling to set properly and prevents a runny pie. Serve warm or at room temperature with a scoop of vanilla ice cream for the ultimate experience!

Dietary considerations for 9 inch blueberry pie

Gluten-Free Adaptations

For a gluten-free version, swap the all-purpose flour in the crust for a 1:1 gluten-free flour blend like Bob's Red Mill or King Arthur Measure for Measure. Use 2.5 cups of the blend plus 2 tbsp extra gluten-free flour for rolling to prevent sticking.

The filling stays the same, but add 1 extra tbsp cornstarch to compensate for the different texture. Chill the dough 30 minutes longer to prevent crumbling during assembly. 🌾

Dairy-Free Crust

Replace the 0.75 cup butter with 0.75 cup dairy-free margarine or coconut oil for a vegan crust. Use King Arthur Vegan Baking Mix for the flour to ensure proper binding.

The filling remains unchanged, but brush the lattice with 1 tbsp maple syrup instead of the egg wash for a glossy finish. This keeps the pie flaky and delicious without dairy. 🥥

Lower Sugar Options

Reduce the 1.5 cups granulated sugar to 1 cup and add ¼ cup honey or maple syrup for natural sweetness. The berries' tartness balances the flavor beautifully. For a diabetic-friendly version, use 1 cup monk fruit sweetener (like Lakanto) and 1 tbsp erythritol for texture.

Taste the filling before baking—adjust sweetness to preference. 🍯

Nut-Free Filling

Skip any nut-based thickeners (like almond flour) and stick with cornstarch or arrowroot powder for thickening. The original recipe already avoids nuts, but if you're concerned about cross-contamination, use a separate bowl and utensils for handling blueberries. Always check your flour for nut-free certifications. 🌰

Allergen-Friendly Storage

Store gluten-free or dairy-free pies in airtight containers with parchment paper between layers to prevent sticking. Label clearly with allergen info. These versions keep well for 3 days at room temperature or 2 months frozen.

Thaw overnight in the fridge before serving to maintain texture. Always reheat to 165°F for safety. ❄️
