Step-by-Step Blueberry Crumble Pie
1. Combine ingredients: In a mixing bowl, mix 1 cup of all-purpose flour with 1/4 cup of granulated sugar. Cut in 1/2 cup of cold, cubed unsalted butter until the mixture resembles coarse crumbs, creating a flaky texture.
2. Form the dough: Gradually stir in 1/4 cup of ice water, one tablespoon at a time, until the dough comes together nicely. Shape it into a disk, wrap in plastic, and refrigerate for 30 minutes to firm up.
3. Prepare the crust: On a floured surface, roll out the chilled dough until it’s about 1/8 inch thick. Fit it into a 9-inch pie dish and trim any excess. Crimp the edges for a beautiful finish.
4. Mix filling: In another bowl, combine 2 cups of fresh or frozen blueberries with 1/2 cup of granulated sugar, 1 tablespoon of cornstarch, 1 tablespoon of lemon juice, and 1/2 teaspoon of cinnamon. Toss gently to coat all the blueberries evenly.
5. Make crumble topping: In a separate bowl, mix together 1 cup of all-purpose flour, 1/2 cup of packed brown sugar, rolled oats, and 1/2 cup of melted unsalted butter until crumbly—this will give your pie that delightful crunch.
6. Assemble and bake: Preheat your oven to 375°F (190°C). Pour the blueberry mixture into the prepared pie crust and sprinkle the crumble topping generously over it for an irresistible finish.
7. Bake to perfection: Place your pie in the oven and bake for about 40-45 minutes until the filling is bubbly and the topping is golden brown. Allow it to cool before savoring every slice!
Optional: Serve warm with a scoop of vanilla ice cream on top!

Tips for the Best Blueberry Crumble Pie
- Butter Temperature: Use cold butter when making the pie crust. It ensures a flaky texture that holds up beautifully under the blueberry filling.
- Chill the Dough: After forming the dough into a disk, refrigerate it for at least 30 minutes. This helps prevent shrinkage while baking.
- Even Coating: When mixing the blueberries with sugar and cornstarch, ensure they are evenly coated. This prevents a watery filling in your Blueberry Crumble Pie.
- Crumble Consistency: Don’t overmix the crumble topping; it should be chunky and crumbly. This texture provides a delightful contrast to the soft filling.
- Baking Time: Keep an eye on your pie as it bakes. If the topping browns too quickly, cover it loosely with aluminum foil to prevent burning while the filling cooks through.
- Cooling Period: Let your pie cool before serving. This allows the filling to set and makes for cleaner slices when serving your delicious Blueberry Crumble Pie.
How to Store and Freeze Blueberry Crumble Pie

- Room Temperature: Let the pie cool completely, then cover it loosely with foil. It can stay fresh for up to 2 days at room temperature.
- Fridge: Store leftover Blueberry Crumble Pie in an airtight container in the refrigerator for up to 5 days. This helps maintain its flavor and texture.
- Freezer: For longer storage, wrap the pie tightly in plastic wrap and aluminum foil, then freeze for up to 3 months. Thaw overnight in the fridge before enjoying.
- Reheating: To reheat, place slices in a preheated oven at 350°F (175°C) for about 10-15 minutes until warmed through, ensuring the crumble stays crispy.

Blueberry Crumble Pie Recipe FAQs
What type of blueberries should I use for my pie?
You can use either fresh or frozen blueberries for this recipe. If using frozen, there’s no need to thaw them; just toss them directly into the filling mixture. Fresh blueberries offer a vibrant flavor and beautiful texture, while frozen ones are equally delicious and convenient.
How do I ensure my pie crust is flaky?
The key to a perfect flaky pie crust is keeping your butter cold! Make sure the butter is cubed and taken straight from the fridge. When you cut it into the flour mixture, aim for a coarse crumb texture—this will help create those lovely flaky layers as it bakes.
Can I make this blueberry crumble pie ahead of time?
Absolutely! You can prepare the pie up to a day in advance. Simply bake it according to the instructions, let it cool completely, then cover it with plastic wrap or aluminum foil and store it in the refrigerator. When ready to serve, reheat in a 350°F (175°C) oven for about 15-20 minutes until warmed through.
What’s the best way to store leftover blueberry crumble pie?
To keep your leftover pie fresh, store it in an airtight container in the refrigerator for up to 3 days. If you prefer keeping it longer, consider freezing individual slices wrapped tightly in plastic wrap and then placed in a freezer-safe bag. They’ll stay good for up to 3 months!
How can I adjust this recipe for dietary restrictions?
If you need a gluten-free option, substitute all-purpose flour with a gluten-free blend that measures cup-for-cup. For dairy-free needs, use coconut oil or margarine instead of butter and ensure that your oats are certified gluten-free if needed.
What if my topping isn’t browning?
If your crumble topping isn’t browning after baking for 40-45 minutes, try broiling it on low for just 1-2 minutes at the end of the baking time. Keep a close eye on it during this time to avoid burning—just until you see that golden color appear!
