1/2 cup (100g) granulated sugar: Sweetens the filling, enhancing the flavor of the blueberries.

1 teaspoon fresh lemon zest: Adds an aromatic citrus note to the filling.

How to Make Blueberry Crumble Pie

Prepare the Crust: Begin by preparing your flaky pie crust, following through to step 5 of your recipe. This step ensures your crust is cold and ready to shape.
Make the Crumble Topping: In a medium bowl, whisk together 1/2 cup brown sugar, 6 tablespoons all-purpose flour, 1/2 teaspoon cinnamon, and 1/8 teaspoon salt. Cut in 5 tablespoons cold unsalted butter using a pastry cutter or a set of forks until the mixture resembles a coarse meal. Stir in 1/2 cup rolled oats and chill in the refrigerator until you’re ready to use it.
Preheat the Oven: Once your pie dough has had some time to chill, preheat your oven to 400°F (204°C).
Prepare the Pie Crust: Roll out the chilled pie dough on a lightly floured surface to a 12-inch circle. Carefully transfer the dough into a 9-inch pie dish, pressing it gently to fit. Trim the excess dough, fold it back over the edge, and crimp the edges for a neat finish. Brush the crust with whisked egg wash and refrigerate for about 10 minutes.
Combine the Filling Ingredients: In a large bowl, toss together 6 cups of fresh blueberries, 1/2 cup granulated sugar, 1/3 cup all-purpose flour, 1 tablespoon cornstarch, 1 tablespoon lemon juice, and 1 teaspoon lemon zest. Mix gently until the blueberries are well-coated; you can mash a few berries to help moisten the mixture.
Assemble the Pie: Spoon the blueberry filling evenly into the prepared pie crust, ensuring the fruit is evenly distributed. Top with the crumble mixture, spreading it generously over the filling.
Bake the Pie: Place the pie in the center of the oven, with a baking sheet on a lower rack to catch any drips. Bake for 25 minutes, then lower the temperature to 375°F (190°C). Cover the edges with a pie crust shield to prevent over-browning and continue baking for another 35-40 minutes, or until the filling is bubbly around the edges and the internal temperature reaches about 200°F (93°C).
Cool Before Serving: Remove the pie from the oven and allow it to cool on a rack for at least 4–5 hours before slicing. This cooling time is essential for the filling to set up properly.
Enjoy: Serve slices of your blueberry crumble pie warm or at room temperature, perhaps with a scoop of vanilla ice cream.

Storing & Reheating

To store your pie, cover it loosely at room temperature for up to 1 day, or transfer it to the refrigerator and keep it in an airtight container for up to 5 days. If you want to save a piece for later, feel free to freeze it for up to 3 months. Thaw overnight in the fridge before reheating in a preheated oven at 350°F (175°C) for about 15 minutes. Keep in mind that the texture might change slightly, but you can always serve it warm to refresh the flavors.

Chef’s Helpful Tips

Avoid a soggy crust by ensuring your pie crust is chilled before adding the filling.
Using cold butter in the crumble topping helps achieve that crumbly texture.
If using frozen blueberries, do not thaw before using; just increase baking time slightly to ensure everything cooks through.
If the fruit filling is too juicy, a little extra cornstarch can help thicken it up.
Consider adding extra spices to the crumble, like nutmeg or cardamom, for added warmth.

At the heart of every gathering is a comforting dish that brings everyone together, and blueberry crumble pie does just that. It’s perfect for any occasion—casual with friends, special holidays, or just because. Each slice is a hug on a plate, ready to delight your loved ones with its warm, sweet flavors. So why not give it a try? You’ll find that the process of making this pie is just as enjoyable as eating it!

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Yes, you can absolutely use frozen blueberries! Just be sure not to thaw them before adding to the filling, as they tend to get mushy. You may need to add a few extra minutes to the baking time to account for their colder temperature.

How do I know when the pie is done baking?

Look for bubbling around the edges of the filling and a golden crumble topping. An instant-read thermometer inserted into the filling should read around 200°F (93°C) when it’s done. If the top is browning too quickly, consider gently covering it with aluminum foil.

How long should I let the pie cool before serving?

It’s best to let the pie cool for at least 4–5 hours before slicing. This cooling period allows the filling to set properly, preventing it from being too runny when you cut into it.

Can I make this pie ahead of time?

Absolutely! You can prepare the pie and keep it unbaked in your fridge for up to a day before baking it. If you prefer, you can also bake it in advance and store it in the refrigerator for a convenient dessert later on. Just warm it up before serving!
