Ingredients You’ll Need

1 unbaked Flaky Pie Crust or All-Butter Pie Crust: A buttery, flaky crust is essential for the perfect base. You can use store-bought for convenience or try my homemade recipe for the ultimate flavor.
1 large egg beaten with 1 Tablespoon milk: This egg wash gives the crust a beautiful golden color and enhances the pie’s visual appeal.
1/2 cup (100g) packed light or dark brown sugar: Adds depth and a slight caramel flavor to the crumble.
6 Tablespoons (46g) all-purpose flour: This flour acts as a binder for the crumble topping, giving it the right texture.
1/2 teaspoon ground cinnamon: Provides a warm, comforting flavor that complements the sweetness of the blueberries.
1/8 teaspoon salt: Balances the sweetness and heightens overall flavor without overpowering.
5 Tablespoons (71g) unsalted butter, very cold and cubed: Cold butter ensures a flakier texture in your crumble topping.
1/2 cup (43g) old-fashioned whole rolled oats: Adds chewiness to the crumble and makes it heartier.
6 cups (about 840g) fresh blueberries: Fresh blueberries are key here; they should be ripe and juicy for the best flavor.
1/2 cup (100g) granulated sugar: Sweetens the filling and harmonizes the tartness of the blueberries.
1/3 cup (41g) all-purpose flour: Thickens the blueberry filling, preventing it from being too runny.
1 Tablespoon cornstarch: Contributes additional thickening power for the filling.
1 Tablespoon fresh lemon juice: Brightens the flavors and balances sweetness with acidity.
1 teaspoon fresh lemon zest: Intensifies the lemon flavor, making the filling bright and fragrant.

How to Make Blueberry Crumble Pie

Make the Pie Crust: Prepare your flaky pie crust according to my recipe until it reaches step 5. This allows the dough to rest, making it easier to roll out.
Prepare the Crumble Topping: In a medium bowl, whisk together the brown sugar, 6 tablespoons of all-purpose flour, ground cinnamon, and salt. Use a pastry cutter or forks to cut in the cubed, very cold butter until the mixture resembles coarse crumbs. Stir in the oats and refrigerate until you are ready to use it.
Roll Out the Dough: Once the pie crust has chilled, preheat your oven to 400°F (204°C). On a lightly floured surface, roll out the chilled dough into a circle about 12 inches in diameter. Carefully transfer the dough to a 9-inch pie dish and press it gently into the bottom and up the sides. Trim any excess, fold the overhanging dough back over itself to create a thicker rim, then crimp the edges with a fork or your fingers. For a lovely finish, brush the edges with the egg wash and refrigerate for at least 10 minutes to maintain the crust’s shape while baking.
Mix the Filling: In a large bowl, combine the fresh blueberries, granulated sugar, 1/3 cup of all-purpose flour, cornstarch, lemon juice, and lemon zest. Mix gently until everything is coated and has a slightly juicy consistency; some blueberries may burst to blend in moisture.
Assemble the Pie: Pour the blueberry filling into the prepared pie crust and spread it evenly. Top with the cold crumble mixture, making sure it covers the entire surface.
Bake the Pie: Place the pie on the center rack of your preheated oven. To catch any bubbling juices, place a baking sheet on the lower rack. Bake the pie for 25 minutes, then reduce the temperature to 375°F (190°C) while keeping the pie inside. If you have a pie crust shield, use it to cover the edges to ensure they don’t burn. Continue baking until the filling bubbles around the edges, about another 35-40 minutes. For a precise measure, the internal temperature of the filling should be approximately 200°F (93°C).
Cool Before Serving: Once baked, remove the pie from the oven and let it cool on a rack for at least 4-5 hours. This cooling time helps the filling set, so it won’t be too juicy when you slice it. Serve with a generous scoop of vanilla ice cream for an extra treat!

Storing & Reheating

To store leftover blueberry crumble pie, cover it and keep it at room temperature for up to 1 day. If you want to keep it longer, refrigerate it for up to 5 days in an airtight container. You can also freeze the pie for up to 3 months; wrap it tightly in plastic wrap and aluminum foil to prevent freezer burn. When you’re ready to enjoy it again, simply reheat slices in the oven at 350°F (175°C) for about 10-15 minutes. The texture may soften a bit, but the flavors will remain just as delightful!

Chef’s Helpful Tips

Avoid a Soggy Crust: Keep your pie crust cold until you’re ready to fill it. This helps it maintain flakiness and prevents it from becoming soggy.
Flavor Boost: Add a pinch of nutmeg to the crumble mixture for an added depth of flavor.
Choose Quality Berries: Always use fresh blueberries for the best taste; frozen might release excess moisture and result in runniness.
Make Ahead: Prepare your pie crust and crumble ahead of time. Store the crust in the refrigerator and the crumble in the freezer, so all you need to do is fill and bake when you’re ready!

Whether you’re reminiscing about summer days or simply indulging in something sweet, blueberry crumble pie offers warmth and comfort in every bite. Feel free to serve it warm with vanilla ice cream or save it for later as a delightful snack or breakfast treat! Enjoy experimenting, making this recipe your own, and sharing it with friends and family. Trust me, they’ll be asking for the recipe!

Recipe FAQs

Can I prepare the pie in advance?

Absolutely! You can make the entire pie a day before serving. Just store it covered at room temperature after it has completely cooled. If you want to prepare it even earlier, you can freeze it; just make sure to wrap it well!

How do I know when the pie is done baking?

The pie is done when the filling is bubbling around the edges and the internal temperature reaches about 200°F (93°C) when checked with a thermometer. The topping should be golden brown.

What’s the best way to serve blueberry crumble pie?

Blueberry crumble pie is delightful on its own, but it’s especially delicious served warm with a scoop of vanilla ice cream or a dollop of whipped cream. Enjoy it at room temperature as a snack or dessert—it’s incredibly versatile!
