Creamy Blueberry Pie

Blueberries are definitely one of the summer’s most popular fruit. It’s easy to see why too: these plump little things pack tons of delicious fruity flavor into each berry! Great for reducing down into a syrup or for lacing cakes with little flavor bombs- I’ve always been a big fan of them. Blueberry Pie is one of the best ways to enjoy blueberries and this Creamy Blueberry Pie recipe is a way to keep things interesting!

This recipe keeps all the things that make Traditional Blueberry Pie delicious but adds in a rich, custard filling. You could just as easily call this Blueberry Custard Pie if you wanted! Whatever you want to call it, just know that it’s delicious: the filling has this perfect balance of sweetness offset by a touch of sour cream. Not only does the sour cream help keep this pie extra creamy and rich but it also keeps the whole thing from becoming cloyingly sweet.

This pie would’ve been delicious enough with just the custard and the blueberries. We didn’t want to stop there, so we hit ours with a little streusel-style crumble topping! This adds a nice buttery, crisp top to the pie- not to mention a little hit of cinnamon and nutmeg. You could easily omit it, but we feel it really pulls the whole pie together.

Enjoyed hot or cold, this pie is certain to be a summertime favorite this year! It might look hard to make, but trust us, this is an easy pie recipe. Just follow along with us- we know you’ll love it!

How to make Blueberry Pie with Sour Cream

1. Mix up the custard filling before adding to a pre-baked pie crust with blueberries.
2. Make some streusel crumble topping before sprinkling over the top of your custard pie.
3. Bake at 350 degrees until golden brown then let cool before serving.

Before starting on the pie, we need to pre-bake our crust. This is as easy as docking the pie crust, filling with pie weights, and baking for 10 minutes at 350 degrees. While that cools, you’ll have some time to prep your custard. For that, beat your eggs and set them aside. In a seperate bowl, whisk together the dry custard ingredients- the sugar, flour, and salt.

Once that’s all whisked up, add in the beaten egg and the sour cream.

With enough whisking, those should all come together into a consistent custard filling for our pie.

Now we can start assembling the pie! First, add your blueberries to your cooled pie crust.

Pour your custard filling over the blueberries and fill up the pie crust.

Give those ingredients a light mix just to even things out. With the filling all sorted out, it’s time to move on to the crumble topping.

How to make crumble topping

This Creamy Blueberry Pie is going to taste great with some of this streusel crumble topping! To make it, first, whisk together all the topping ingredients- minus the butter for right now.

Once those are all mixed up, drop in your butter- cut into small pats. Using something like a pastry cutter or dough blender, start working that butter into the dry streusel ingredients.

With enough work, that should all come together into that crumbly topping that we’re going for. Once you have a workable crumble topping, start sprinkling it over the top of your Blueberry Pie.

Now that our pie’s all topped off, we can finally transfer it to an awaiting 350 degree oven. At 350 degrees, it should take about 50-55 minutes for our pie to pick up a lovely golden-brown color.

When it’s finished baking, pull it from the oven and allow to cool a bit before serving. This pie can be enjoyed warm or cold, with a whipped cream topping, or with a big scoop of ice cream. However you serve our Creamy Blueberry Pie up, we hope you enjoy it!

Make-ahead and freezing

• Generally, custard-based pies do not freeze well- often becoming extra watery when thawed and baked. With that in mind, we wouldn’t recommend freezing this pie.
• We do, however, think you could easily prep the custard filling in advance! Simply mix up the custard filling and keep it in the fridge for 2-3 days before making this Creamy Blueberry Pie with it.
