There’s an old baking debate that pops up every summer: do you make a classic pie with a flaky top crust, or a rustic fruit crisp?
If you ask me, you shouldn’t have to choose.
This Blueberry Crumble Pie is the ultimate best of both worlds. You get a rich, jammy blueberry filling nestled inside a buttery pie shell, all covered in a thick layer of cinnamon-brown sugar streusel. Every bite gives you that perfect contrast of a crunchy, cookie-like top and a tender crust on the bottom.
The real secret here? We cook a portion of the blueberry filling on the stove for a few minutes before it ever goes into the oven. This simple step activates the cornstarch so the juices thicken properly, guaranteeing you get a clean, thick slice that doesn’t puddle all over the plate.
Whether you love making pie crust from scratch, rolling out store-bought dough, or popping open a pre-made frozen crust, this recipe turns out beautifully every single time.
Why You’ll Love This Recipe
-
No Runny Slices: Pre-cooking part of the filling sets the juices so your pie holds its shape when sliced.
-
Fresh or Frozen Berries: Works just as well with summer blueberries as it does with frozen berries in the dead of winter (no need to thaw them first!).
-
Big, Crunchy Streusel Clumps: Melting the butter instead of cutting cold butter in makes big, golden crumble pieces that stay crisp.
-
Bright Flavor: A touch of fresh lemon zest cuts through the sweetness and makes the blueberry flavor pop.

Yield: 1 (9-inch) deep-dish pie
Ingredients
The Crust
-
1 (9-inch) unbaked pie shell (homemade, refrigerated rolled dough, or frozen)
The Streusel Topping
-
1 cup all-purpose flour
-
1 cup light brown sugar, packed
-
2 tsp ground cinnamon
-
1/2 tsp fine salt
-
6 tbsp unsalted butter, melted
The Jammy Blueberry Filling
-
3 1/2 cups fresh or frozen blueberries (divided; do not thaw if frozen)
-
1/3 cup granulated sugar
-
1/4 cup cornstarch
-
2 tsp fresh lemon juice
-
1/1 tsp freshly grated lemon zest
-
1/4 tsp salt
-
2 tbsp water
Step-by-Step Instructions
1. Mix and Chill the Streusel
In a medium bowl, whisk together the flour, brown sugar, cinnamon, and salt. Pour in the melted butter and stir with a rubber spatula until nice, big clumps form. Pop the bowl into the freezer while you work on the filling so the butter stays cold.
2. Pre-Cook the Berry Filling
In a medium saucepan, whisk together 2 cups of the blueberries, the sugar, cornstarch, lemon juice, lemon zest, salt, and water until the cornstarch dissolves.
Set the pan over medium heat and bring to a gentle simmer, stirring continuously. The berries will burst and turn into a thick, shiny purple glaze in about 4 to 5 minutes. Remove from the heat, stir in the remaining 1 1/2 cups of whole blueberries, and let it cool to room temperature.
3. Assemble
Fit your crust into a 9-inch pie pan (or grab your frozen shell). Once the blueberry filling has cooled down, scoop it into the pie shell and smooth it out. Take your streusel out of the freezer and scatter those chilled crumble pieces evenly over the top, covering the berries completely.
Put the whole assembled pie in the fridge for a few minutes while you preheat your oven to 350°F. Set your oven rack to the lower third position and line a baking sheet with parchment paper.
4. Bake
Set the pie onto your baking sheet (to catch any stray drips) and bake for 50 to 55 minutes. You’re looking for a deep golden-brown crumble top and thick, lazy purple bubbles around the edges.
-
Baker’s Tip: Check the pie around the 40-minute mark. If the crumble top is browning too fast, loosely tent a sheet of aluminum foil over the pie for the last 10 to 15 minutes.
5. Cool completely
Transfer the pie to a wire rack. Resist the urge to slice into it right away—letting it cool completely to room temperature gives the filling time to fully set so every slice cuts cleanly.
Storage & Serving
-
Serving: Best served slightly warm with a scoop of vanilla ice cream or a dollop of fresh whipped cream.
-
Storage: On the first day, leave the pie loosely covered at room temperature to keep the streusel topping crunchy. After that, cover and refrigerate for up to 2 days.
