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 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.

*Sugar Note: When testing my recipes, I use a homemade sugar mixture composed of equal parts sugar and equal parts of the Swerve sugar substitute equivalent. I personally find this 1/2 and 1/2 mixture of Sugar and Swerve to be the only sugar substitute mix that does not compromise on taste or texture in baking. Using this ratio cuts the overall sugar in half in recipes and my family still loves the taste. Swerve is available as granulated sugar, brown sugar and confectioner’s (powdered) sugar.

    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 🙂
