Anna Olson's Blueberry Pie Recipe: Buttery Crust and Bursting Berries

Anna Olson's blueberry pie recipe delivers that perfect balance of buttery crust and juicy, spiced blueberries that makes every slice irresistible. 💛 The secret lies in a flaky homemade crust that holds its shape while baking, paired with a filling thickened just enough to keep those berries from turning to syrup.

I've perfected this recipe over years of testing—it's the kind of pie that disappears faster than you can say "second helping."

What sets this pie apart is the two-stage cooking process: first baking the filling to thicken it, then adding the crust to create that golden, bubbling top. The blueberries stay plump and juicy while the crust achieves that ideal crispy yet tender texture.

This method ensures your pie won't be soggy at the bottom or dry at the top—just right every time.

By the time you pull it from the oven, you'll have a pie with a caramelized crust, a lattice of golden-brown berries, and that signature cinnamon-spiced aroma that fills your kitchen.

The filling is thick enough to hold a spoon yet still releases juices with each bite. It's the kind of dessert that makes summer gatherings feel extra special.

Serve it warm with a scoop of vanilla ice cream or whipped cream for the full experience. For those with dietary needs, a gluten-free crust option is included without sacrificing flavor. Let's get baking—this pie is worth every minute of prep time.

Buttery crust, juicy berries, and a touch of cinnamon make this pie worth every bite.

The blueberries should be fresh and firm—no mushy ones. Local farmers markets often have the best quality, but the grocery store works too. For the crust, cold butter is non-negotiable—cut it into cubes and keep it in the freezer until ready to use. If you're short on time, King Arthur Flour or Bob's Red Mill gluten-free blends work perfectly for the alternative crust. The oats in the filling add a pleasant texture, but if you're out, blend your own from rolled oats—it's a game-changer.

No fresh blueberries? Frozen work great—just don't thaw them first. Short on butter? Coconut oil or vegan butter keeps it flaky. The filling can handle a bit of extra sugar if you're serving kids, but stick to the recipe for that perfect balance. For the crust, chilled dough is key—wrap it in plastic and refrigerate for at least 30 minutes before rolling. The cornstarch is what keeps those berries from turning to syrup, so don't skip it.

The crust dough keeps for 3 days in the fridge, wrapped tightly. The filling can be prepped ahead and stored for 24 hours before baking. Once baked, this pie tastes even better the next day—cover loosely with foil if storing overnight. For the gluten-free crust, add an extra tablespoon of ice water to help bind it. Freeze any leftovers for up to 3 months—just thaw at room temperature before serving.

Step-by-step instructions for Anna Olson's blueberry pie

Here's how to create Anna Olson's legendary blueberry pie with a flaky crust and berries that burst with every bite.

In a large bowl, combine the 3.5 cups all-purpose flour (plus 1 tablespoon for dusting) with 0.5 teaspoon salt. Cut in the 1.25 cups cold cubed unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is crucial for flaky layers.

Drizzle in the 0.5 cup ice water all at once and gently stir with a fork until the dough just comes together. Be careful not to overmix—just until the dough holds when pressed. Turn it out onto a lightly floured surface and divide into two equal disks. Wrap each in plastic and chill for at least 30 minutes (or up to 2 days).

In a large bowl, combine the 4 cups fresh blueberries with the 1.5 cups granulated sugar, 0.5 cup light brown sugar, 2 tablespoons cornstarch, 2 tablespoons lemon juice, 1 teaspoon vanilla extract, and 2 tablespoons ground cinnamon. Gently toss until all berries are evenly coated. Let the mixture sit for 15 minutes—this allows the sugars to break down slightly and intensify the flavors.

In a separate small bowl, blend the 0.5 cup old-fashioned oats until they become a fine powder. Sprinkle this over the berry mixture and toss again to distribute evenly. This oat flour creates that signature Anna Olson texture that thickens the filling beautifully without making it gummy.

Preheat your oven to 375°F. Roll out one of the chilled dough disks on a floured surface to fit a 9-inch pie dish, leaving a ½-inch overhang on all sides. Transfer the dough to the pie dish and press it gently into the bottom and up the sides. Trim the excess dough, leaving about ½-inch for crimping later.

Pour the blueberry filling into the prepared crust, spreading it evenly. Roll out the second dough disk and cut it into ½-inch wide strips for the lattice top. Arrange the strips in a crisscross pattern, leaving a ½-inch gap between them for steam to escape. Brush the lattice with a little ice water to help it stick.

Place the assembled 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 is bubbling vigorously. The edges should be golden, not pale—this indicates proper browning and crispness.

For the last 10 minutes of baking, place a ½-inch thick baking sheet on the rack below the pie. This creates steam that helps the bottom crust crisp up nicely. When done, the filling should be thick but still slightly jiggly in the center.

Remove the pie from the oven and let it cool 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. If you can't wait, dust the top with extra ground cinnamon while still warm for a beautiful presentation.

Serve each slice warm with a scoop of vanilla ice cream or whipped cream. The contrast of the warm, spiced berries with cool dairy is what makes this pie truly special. Store any leftovers in the refrigerator for up to 4 days, though I doubt it'll last that long!

Pro cooking tips for this recipe

Crust Perfection

For a truly flaky crust, I can't stress enough how important it is to keep that butter cold—like, straight-from-the-freezer cold. Cut it into ½-inch cubes and pulse them in your food processor with the flour before adding ice water.

This creates even distribution of fat for those perfect layers. If your dough feels too dry, add 1 teaspoon ice water at a time—overworking it kills flakiness. 🧈

Filling Texture

The secret to Anna Olson's signature filling is that oat flour—it thickens beautifully without gumming up the berries. Pulse ½ cup old-fashioned oats in your food processor until it's a fine powder.

Let the filling sit for 15 minutes before baking to let the sugars caramelize slightly, which deepens the flavor. And never skip the cornstarch—it's what keeps those juices from turning into a syrup.

Two-Stage Baking

Here's my pro move: bake the filling for 20 minutes uncovered first, then add the lattice top. This creates a thicker, more stable filling that won't leak through the crust.

For the lattice, cut strips ½-inch wide and arrange them in a crisscross pattern with ½-inch gaps—this lets steam escape while keeping the berries visible. Brush the strips with ice water before baking to help them stick together.

Steam Trick

Place a ½-inch thick baking sheet on the rack below your pie for the last 10 minutes of baking. This creates steam that crisps the bottom crust beautifully. I learned this from watching professional bakers—it's what makes the difference between a good pie and a showstopper.

The edges should be golden brown, not pale, which means they've properly browned and crisped.

Cooling Matters

Resist the urge to slice that pie immediately! Let it cool on a wire rack for at least 2 hours—this gives the filling time to set properly. If you can't wait, dust the warm pie with extra cinnamon for a gorgeous finish.

The contrast between the warm, spiced berries and cool crust is what makes this pie unforgettable. Trust me, the wait is worth it. 💛
