Ingredients You’ll Need

1 unbaked Flaky Pie Crust or All-Butter Pie Crust: This is the base of your pie; homemade adds that extra touch but store-bought works just fine.
Egg wash for pie crust: 1 large egg beaten with 1 Tablespoon milk, helps achieve that beautiful golden color on your crust.
1/2 cup (100g) packed light or dark brown sugar: This adds sweetness and a rich depth of flavor to the crumble topping.
6 Tablespoons (46g) all-purpose flour (spooned & leveled): A thickening agent, it helps create that contrasting texture of the crumble.
1/2 teaspoon ground cinnamon: Enhances the flavors with a warm spice that pairs beautifully with blueberries.
1/8 teaspoon salt: A little salt balances the sweetness and heightens the flavors.
5 Tablespoons (71g) unsalted butter, very cold and cubed: The cold butter will create a wonderfully flaky topping, so don’t skip this step!
1/2 cup (43g) old-fashioned whole rolled oats: Adds a lovely chewiness and heartiness to the crumble.
6 cups (about 840g) fresh blueberries: The star of the show! Fresh blueberries give the pie its juicy filling.
1/2 cup (100g) granulated sugar: Sweetens the blueberry filling, making it irresistible.
1/3 cup (41g) all-purpose flour: Thickens the blueberry filling, ensuring it’s not too runny.
1 Tablespoon cornstarch: Helps to further thicken the filling and keeps it stable.
1 Tablespoon fresh lemon juice: Brightens the flavors, giving the blueberries a fresh zing.
1 teaspoon fresh lemon zest: Adds an aromatic depth that’ll elevate the blueberry taste.

How to Make Blueberry Crumble Pie

Prepare the Pie Crust: If you’re making a homemade crust, follow my butter pie crust recipe through step 5 to achieve a perfectly flaky base.
Make the Crumble Topping: In a medium bowl, whisk together the 1/2 cup packed brown sugar, 6 tablespoons all-purpose flour, 1/2 teaspoon ground cinnamon, and 1/8 teaspoon salt. Cut in the 5 tablespoons very cold cubed unsalted butter using a pastry cutter or fork until the mixture resembles coarse crumbs. Stir in the 1/2 cup rolled oats, then refrigerate the topping until ready to use.
Preheat the Oven: Once your pie dough has chilled for at least 30 minutes, preheat your oven to 400°F (204°C).
Roll Out the Dough: On a lightly floured surface, roll out the chilled pie dough into a circle about 12 inches in diameter. Gently place the dough into a 9-inch pie dish, tucking it into the edges. For a decorative touch, fold the overhanging dough back over the edge and use your fingers to crimp the edges. Brush the exposed crust edges with egg wash and refrigerate for another 10 minutes to keep it cold.
Prepare the Filling: In a large bowl, combine 6 cups of fresh blueberries, 1/2 cup granulated sugar, 1/3 cup all-purpose flour, 1 tablespoon cornstarch, 1 tablespoon fresh lemon juice, and 1 teaspoon fresh lemon zest. Mix until everything is well-coated and slightly moistened. A few blueberries can be intentionally burst to help with moisture.
Assemble the Pie: Spoon the blueberry filling into the chilled pie crust and then top it evenly with the cold crumble topping you prepared earlier.
Bake the Pie: Place the pie on the center oven rack with a baking sheet underneath to catch anything that bubbles over. Bake for 25 minutes at 400°F (204°C). Without opening the oven, reduce the temperature to 375°F (190°C). Cover the edges with a pie crust shield to prevent over-browning and bake for an additional 35—40 minutes. The pie is done when the filling is bubbling around the edges, and an instant-read thermometer shows around 200°F (93°C).
Cool Before Serving: After baking, let the pie sit on a cooling rack for at least 4-5 hours. This cooling period allows the filling to set, giving you clean slices when serving. I promise you’ll want to let it cool fully to avoid a juicy mess!
Store Leftovers: Cover and keep any leftover pie at room temperature for up to 1 day or in the refrigerator for up to 5 days.

Storing & Reheating

Store your blueberry crumble pie at room temperature for up to 1 day, or refrigerate for up to 5 days in an airtight container. If you want to keep it longer, freeze it tightly wrapped for up to 3 months. To reheat, simply place slices in a 350°F (175°C) oven for about 15-20 minutes until heated through. The flavors may mellow a bit upon reheating, but a scoop of vanilla ice cream on top always perks it right back up!

Chef’s Helpful Tips

Make sure your butter is cold when incorporating it into the crumble topping. This is key to achieving a flaky texture.
If your blueberries are particularly sweet, you might adjust the sugar in the filling to suit your taste.
Consider mixing in a handful of other berries for a delightful twist, such as raspberries or blackberries.
Be cautious not to overbake the pie; keep an eye on those edges to ensure they don’t get too dark.
If you’re in a hurry, using a store-bought crust can still yield delicious results, but the homemade crust is so worth the effort!

Blueberry crumble pie combines comforting flavors and delightful textures to create a dessert that your guests—the whole family—will simply love. Whether you’re celebrating a special occasion or simply winding down after a long day, this pie is sure to impress with its harmony of flavors and its welcoming, fresh appeal. Feel free to experiment with the filling or even the crumble topping to tailor it to your preferences. Enjoy every bite!

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! If using frozen blueberries, do not thaw them before adding them to your filling. This helps retain their shape and juices while baking. You might want to increase the cornstarch a little to help absorb the excess moisture.

How do I know when the pie is done baking?

Your pie is done when the filling is bubbling around the edges and the internal temperature reaches about 200°F (93°C). If you’re unsure, a neat tip is to keep an eye on the crust edges, which should be golden brown.

Can I make this pie ahead of time?

Yes, you can make the pie a day in advance. Just cover and store it in the refrigerator. Alternatively, assemble the pie and freeze it before baking. Bake it from frozen, adding additional time as needed.

What can I serve with blueberry crumble pie?

A scoop of vanilla ice cream or a dollop of whipped cream pairs wonderfully with the pie. Alternatively, serving it with a drizzle of lemon glaze can elevate the dessert.
