- Flour: You want all-purpose flour for each the filling (to thicken) and within the crumb topping (for construction).

Blueberries include a stunning quantity of liquid, and the cornstarch (paired with the flour) is crucial for serving to the filling set into clear slices after cooling.
- Sugar: Blueberries are naturally candy, so this recipe makes use of simply sufficient sugar to reinforce their taste with out overpowering it. You want granulated sugar for the filling and brown sugar for the crumble topping.
- Recent Lemon Zest & Juice: Recent lemon brightens the berries and retains the filling tasting vibrant fairly than overly candy (or one-note).
- Cinnamon: Solely a small quantity is required for the topping. It provides heat with out making the pie style closely spiced.
- Outdated-Usual Complete Oats: These add texture and assist create these crisp, buttery crumbles on high.

Overview: Learn how to Make Every Element of Blueberry Crumble Pie
Put together the pie dough: Make the pie dough forward of time and chill it for at the least 2 hours. Begin with my favourite all-butter pie crust. It bakes up exceptionally flaky and is simple to work with. You may additionally use this butter/shortening pie crust, which holds form properly. Each recipes yield 2 crusts, so you’ll be able to pop one into your freezer for the following time you crave blueberry crumble pie.
Make the crumble topping: Make the oat crumble topping first and refrigerate it whilst you put together the filling. Maintaining the topping chilly helps it bake into crisp, distinct crumbles fairly than melting into the filling. Use chilly and cubed butter, reduce it into the brown sugar, flour, cinnamon, and salt utilizing a pastry cutter or 2 forks, then stir within the oats.

Make the filling: Blueberry pie filling is definitely one of many quickest fruit pie fillings to organize! There’s no peeling, pitting, hulling, or chopping the fruit. Not like triple berry pie, you do NOT must pre-cook the filling both (a step we examined however discovered ineffective). Simply rinse and pat the berries dry after which toss them with sugar, flour, cornstarch, lemon juice & zest.
One particularly vital success tip: In case your filling appears to be like dry and powdery, your baked pie filling will probably be cloudy and runny. In case your filling appears to be like shiny and juicy, your baked pie filling will set fantastically.


Mash just a few blueberries to assist take up among the flour and cornstarch, so your filling appears to be like juicy. Place the filling within the fridge whilst you end your pie crust.
Fill the pie crust: Roll the chilled pie dough right into a 12-inch circle, and match it right into a 9-inch deep-dish pie plate. I like to recommend utilizing a glass pie dish, so you’ll be able to see when the crust on the edges is browning. Flute or crimp the pie crust edges, then brush the perimeters with an egg wash.
Add the blueberry filling and high with the chilly crumble topping. Don’t be shy with the crumble! It might appear to be so much earlier than baking, however it settles because the pie bakes and creates that impossible to resist crunchy topping all of us love.

Baking & Cooling Steps
These steps are significantly vital to this recipe, so don’t be tempted to shorten the instances or take any shortcuts right here.
Begin baking the pie at a excessive temperature. Why? Baking this pie at 400°F (204°C) for 25 minutes helps set the pie crust form, and helps the cornstarch and flour start thickening the filling. After that, cut back the oven temperature right down to 375°F (190°C) to proceed baking the pie. We use this similar trick once we make strawberry rhubarb pie and peach pie as nicely.
In the event you discover the perimeters of the crust are getting too darkish, add a pie crust protect. And if the crumb topping is browning too shortly, tent a bit of foil over the complete pie to stop it from over-browning, whereas giving the filling the time it wants to complete baking.
Learn how to Inform When Your Pie Is Accomplished
Don’t decide doneness by crust colour alone. The blueberry juices needs to be actively effervescent across the edges earlier than it comes out of the oven. These bubbles point out the cornstarch has reached the temperature wanted to correctly thicken the filling.
For a extra correct check of doneness, test the pie with an instant-read thermometer; the inner temperature ought to attain 200°F (93°C).
This could be the toughest half: it’s important to let it cool for a number of hours (in a single day is even higher). Throughout this time, the filling thickens and absolutely units. In the event you reduce into it too quickly, it will be runny—regardless of how nicely you baked it.
On the plus facet, meaning blueberry crumble pie is a superb make-ahead dessert! Good for internet hosting summertime celebrations like Father’s Day, 4th of July, commencement events, Labor Day, and extra.

When you slice into that completely baked and cooled pie, you’ll understand it was well worth the wait. Heat your slice again up, then add a scoop of ice cream and a dollop of home made whipped cream for good measure. Pie perfection.
