This Blueberry Crumble Pie is everything a summer dessert should be: juicy blueberries bubbling under a golden, buttery crumble that stays wonderfully crisp. I first made this pie on a whim one July afternoon when my neighbor Sofia showed up with a basket of blueberries from the farmer's market, and it's been my go-to ever since. The best part? You don't need any fancy techniques, just fresh berries and a little patience while it cools.

What Makes This Blueberry Crumble Pie So Special
There's a reason this fresh Blueberry Crumble Pie has become one of my most-requested recipes. Unlike traditional double-crust pies, the crumble topping adds texture without the fuss of a lattice. The filling thickens beautifully thanks to a combination of flour and cornstarch, and the hint of lemon zest brightens everything up without overpowering the berries.
This is one of those homemade fruit pies that looks like it came from a bakery but comes together with ingredients you probably already have in your pantry.

See Recipe Card Below This Post For Ingredient Quantities
For the Pie Crust:
- Homemade pie crust: You'll need just one crust for this recipe. A buttery, flaky base holds all that juicy filling without getting soggy.
For the Filling:
- Fresh blueberries: The star of the show. Fresh berries give the best flavor and texture, though frozen will work in a pinch.
- Granulated sugar: Sweetens the filling and balances the tartness of the blueberries.
- All-purpose flour: Works with the cornstarch to thicken the filling as it bakes.
- Cornstarch: Helps create that perfect, sliceable consistency without making the filling gummy.
- Lemon juice: Adds brightness and keeps the filling from tasting flat.
- Lemon zest: Brings a fresh, citrusy note that makes the blueberries shine.
For the Crumble Topping:
- Brown sugar: Adds a hint of molasses sweetness and helps the topping caramelize.
- All-purpose flour: Gives the crumble structure so it bakes up crisp.
- Ground cinnamon: A warm spice that complements the berries beautifully.
- Unsalted butter: Cold butter is key here. It creates those buttery crumbs that turn golden in the oven.
- Old-fashioned rolled oats: Adds texture and a slightly nutty flavor to the topping.
How to Make Blueberry Crumble Pie
Follow these steps to make the best Blueberry Crumble Pie from scratch.
Prepare the crust: Follow my pie crust recipe through step 5. You'll want the dough chilled and ready to roll.
Make the filling: In a large bowl, toss together the blueberries, granulated sugar, flour, cornstarch, lemon juice, and lemon zest until everything is evenly coated. Don't worry if it looks a little floury at first. Pop the bowl in the fridge while you work on the crust.
Preheat oven: Set your oven to 400°F (204°C) so it's nice and hot when the pie goes in.
Roll out pie dough: On a lightly floured surface, roll out one disc of chilled dough. Give it a quarter turn every few rolls until you've got a circle about 12 inches across. Carefully transfer it to a 9-inch pie dish and press it gently into the bottom and sides. Pour in the chilled blueberry filling, leaving behind any extra juice that's pooled at the bottom of the bowl.
Prepare the crumble: In a medium bowl, whisk together the brown sugar, flour, and cinnamon. Add the cold cubed butter and use a pastry cutter to work it into the dry ingredients until you've got coarse, pea-sized crumbs. Stir in the oats, then sprinkle the whole mixture evenly over the blueberries.
Bake the pie: Set the pie on a large baking sheet to catch any drips. Bake for 25 minutes at 400°F, then lower the temperature to 375°F (190°C) and bake for another 30 to 35 minutes. About 20 minutes into baking, place a pie crust shield around the edges to keep them from getting too dark, and loosely cover the top with foil so the crumble doesn't brown too fast.
Cool the pie: This is the hardest part. Let the pie cool at room temperature for a full 3 hours. I know it's tempting to dig in early, but the filling needs time to set up properly.
Serve: Slice into wedges and serve as is, or add a scoop of vanilla ice cream for the full experience.
Smart Substitutions
No fresh blueberries? You can use frozen, but don't thaw them first. The pie will need a few extra minutes in the oven to account for the extra moisture.
Out of cornstarch? Use an extra tablespoon of flour instead. The filling might be slightly less glossy but will still set.
Don't have brown sugar? White sugar works in the crumble topping, though you'll lose a bit of that caramel-like depth.
No oats on hand? You can leave them out or swap in chopped nuts like pecans or almonds for crunch.
Equipment For Blueberry Crumble Pie
- Glass mixing bowl: For tossing the filling and making the crumble.
- Rolling pin: To roll out your pie dough evenly.
- 9-inch pie dish: The perfect size for this recipe.
- Pastry cutter: Makes cutting the butter into the crumble topping so much easier.
- Pie crust shield: Protects the edges from over-browning during the long bake.
Storage and Make-Ahead Tips
This Blueberry Crumble Pie actually tastes even better the next day once the flavors have had time to settle.
Room temperature: The Blueberry Crumble Pie can sit out, loosely covered, for up to 2 days.
Refrigerator: Cover tightly and store for up to 4 days. Bring it back to room temperature before serving, or warm individual slices in the microwave for 15 to 20 seconds.
Freezer: Once the pie is completely cooled, wrap it tightly in plastic wrap and then foil. Freeze for up to 3 months. Thaw overnight in the fridge before serving.
Make-ahead tip: You can prepare the pie dough up to 5 days in advance and keep it in the fridge, or freeze it for up to 3 months. The assembled pie can also be made a day ahead, covered, and refrigerated until you're ready to serve.
Serving Suggestions
This Blueberry Crumble Pie is delicious on its own, but here are a few ways to make it extra special:
- Vanilla ice cream: A scoop of cold ice cream melting into the warm pie is pure heaven.
- Whipped cream: Light and airy, it balances the richness of the crumble.
- Greek yogurt: For a slightly tangy twist, serve a dollop alongside your slice.
- Fresh mint: A few leaves on top add a pop of color and a hint of freshness.
Pair it with a cup of coffee or tea, and you've got yourself the perfect afternoon treat. If you're looking for more dessert inspiration, my Vanilla Cupcakes and Pinwheel Cookies are always a hit.
Expert Tips
Use cold butter: When making the crumble, keep your butter as cold as possible. This creates those buttery pockets that bake up crisp and golden.
Don't skip the cooling time: I know three hours feels like forever, but cutting into the Blueberry Crumble Pie too soon will leave you with runny filling. Patience pays off here.
Save extra juice: If your blueberries release a lot of liquid while sitting, drain it off before pouring the filling into the crust. Too much juice can make the bottom soggy.
Check for doneness: The filling should be bubbling around the edges, and the crumble should look golden and set. If the topping is browning too fast, tent it with foil.
Rotate halfway through: If your oven has hot spots, rotate the Blueberry Crumble Pie halfway through baking for even browning.

FAQ
Should I prebake my pie crust for blueberry pie?
No, you don't need to prebake the crust for this Blueberry Crumble Pie. The long baking time is enough to cook the bottom crust through, especially with the crumble topping protecting the filling from drying out.
How to make crumble blueberry?
The crumble is simple: mix brown sugar, flour, and cinnamon, then cut in cold butter until you have coarse crumbs. Stir in oats and sprinkle it over your blueberry filling before baking. The key is keeping that butter cold so it doesn't melt into the dry ingredients too soon.
What is the best thickener for blueberry pie?
A combination of flour and cornstarch works beautifully. The flour adds body, while the cornstarch gives you that glossy, sliceable filling without any starchy aftertaste. Some bakers use tapioca, but I find this combo the most reliable.
What is the secret to good crumble?
Cold butter and the right ratio of fat to dry ingredients. You want pea-sized crumbs that hold together when squeezed but still crumble apart easily. Don't overwork the mixture, or it'll turn into dough instead of staying light and crumbly.
