Why I love this blueberry crumble pie

Summer is almost over and for once, I’m not ready to let it go. After months of doing pretty much nothing, we’ve gotten into quite the groove.

There’s been lots of sleeping in and lounging by the pool. I’m 100% not ready for virtual school to start next week

So this week, we’re indulging as much summer as we can. Grilled chicken, tomato salad, rose sangria, blueberry crumble pie.

It’s all perfect and free from responsibility, which I’ll take any day this year.

Here’s what you’ll need to make it

Ingredient notes: I’ve used my vegan pie crust for this recipe, but you can easily swap it out for store bought crust. Most brands are naturally dairy free, so it’s a great shortcut.

How to make blueberry pie with crumb topping

Make the blueberry pie filling. Add the blueberries to a large mixing bowl. Add sugar, lemon juice, cornstarch and cinnamon. Stir until the blueberries are evenly coated in the cornstarch and the lemon juice makes it all look a bit wet.

Assemble the pie. Place the pie crust into the pie plate, gently pressing the crust into the sides. Cut off the excess and crimp the pie crust edges into a scallop (totally optional, only do this if you want to).

Mix the crumble topping. With the topping ingredients together in a mixing bowl. Then cut in the cold (as cold as you can get it!) shortening until a crumb forms. Top the pie with the crumble.

Bake the pie. Once the crumble is on the top of the pie, bake it for 45 – 55 minutes, or until the crumble is golden brown and the filling is bubbling.

Remove it from the oven and let the pie rest until it’s completely cooled to room temperature. This step is important because the pie needs to set. If you rush this or skip it, the pie will fall apart when slicing.

FAQS and tips for making the best blueberry pie

What is the best thickener for blueberry pie?

I find that cornstarch is the best thickening agent for blueberry pie. You don’t need a ton of it so the flavor isn’t too overwhelming and the cornstarch stands up to long periods of heat (like the pie baking).

Why is my blueberry pie runny?

If your pie is runny, it hasn’t cooked long enough or you didn’t let it cool for a long enough time. If you didn’t bake your pie long enough, the pie will cornstarch will not thicken. Cooling is also necessary for the cornstarch to do it’s job and thicken the pie. Don’t rush this step.

How long does a blueberry pie last?

Blueberry pie should be good for 4 – 5 days.
