Homemade Gluten-Free Blueberry Pie

Look no further for the absolute BEST Gluten-free Blueberry Pie recipe. With a foolproof gluten-free pie crust and a thick, rich homemade blueberry filling, this pie is a dessert your whole family will love.

Gluten-Free Blueberry Pie

I may be wrong, but in the nearly 10 years I’ve been blogging (where did that time go?) I don’t think I’ve ever blogged about Pi Day.

…which is kinda odd, because my family (other than me) is made up of a bunch of math nerds. My husband has a mental math ability that’s almost super human and my kids seem to have inherited it.

Plus, my dad is known as “Pi”… it’s his “given” grandfather name, based on a nickname he developed — as I understand it — as an engineering student at Auburn University many moons ago.

So the idea of celebrating 3.14 each year with “pie” on Pi Day isn’t one that’s lost on me. I guess I’ve just never had a recipe that felt celebration worthy.

Until this:

Gluten-Free Blueberry Pie

Perfecting this Gluten-Free Blueberry Pie has been my test kitchen obsession for the last three weeks. I stumbled into this quest after my friend Gretchen (of kumquatblog.com) and I were having a discussion about gluten-free pastry and she twisted my arm to try her Perfect Grain-Free Pie Crust:

Honestly, I had my doubts that it would wow me the way Gretchen said it would.

But hear me loud and clear.

I. Was. Wrong.

I knew the minute I tasted the first bite of this Gluten-Free Blueberry Pie that the crust was every bit as good as she said it would be.

The only problem was that I goofed the filling. I used only fresh blueberries and it was a watery mess on the inside.

Back to the drawing board I went, cooking the filling first, but ending up with too few fresh blueberries.

If you’re sensing a Goldilocks and The 3 Bears pattern here, you’ll know this last one was the one that was JUST RIGHT. A filling of both cooked blueberries & fresh, all nestled inside Gretchen’s Perfect Grain-Free Pie Crust.

Gretchen and I may not be math wizards (or maybe she is and I just don’t know it?) But I can tell you we’re wizards in the test kitchen (read more on her post about that backstory). Her crust + my filling = THE Best Gluten-Free Blueberry Pie.

    This is my son’s new and favourite pie- and he doesn’t normally like pie. The filling is also lovely over vanilla ice cream.

    I substituted the sugar for 1/2 cup maple sugar and reduced the water by 3 tablespoons. I also substituted xylitol for sugar when making the crust. The crust is amazing.

      Oh I’m SO happy to hear this! Glad the changes were successful. And I agree… that crust is divine 🙂
