It’s not at all a blackberry pie, but since most people can’t get Marionberries I wanted to be sure you knew that this could be a blackberry pie recipe. But it’s really the ultimate marionberry pie!

If you know me at all, like even for 5 minutes you know that I am obsessed with two things, no three things in the food world.
- Marionberry Pie
- Margarita Pizza
- Hot French Fries
There’s plenty of other loves too, tacos, squishy rolls, and so on, but man, those three are really, really hard for me to turn down.
I was walking through the grocery store last year and spotted them, Marionberries!!! I knew that this was no coincidence. I had to buy them all and make the ultimate marionberry pie.

And I did.
I am not very tall, a mere 5’3 and the berries were high on a shelf. But I’m not scared.
I carefully placed my right toes on the shelf, gently nudging back the produce to fit.
One hand grabbed a shelf higher up and, hhhuuuuggghh, I hauled myself up and started pulling every container into my cart.
Every.
Single
One.
And I don’t feel bad.
What are Marionberries?
Are marionberry and huckleberry the same thing? No, a huckleberry is more like a blueberry.
Marionberries are a cross between two breeds of blackberry and taste like a blackberry mixed with a raspberry. You get the sweetness of the raspberry with the extra flavor of the blackberry.
It’s pretty much the most perfect berry in all the land.
Like, seriously.

Where to Buy Marionberries?
Marionberries are mostly found in Oregon, specifically around Salem, but you can find them in parts of Washington as well.
When is marionberry season in oregon?
Marionberry season is between July and August in Oregon which is one of the best times to visit. You can head out to the coast and stop at any roadside stand to buy marionberries.

What to Substitute for Marionberries
If you can’t find marionberries in your produce department you probably live outside of the Pacific Northwest, the place I grew up.
But don’t fear, blackberries are a great substitute for Marionberies.
Or if you aren’t a blackberry fan, this Razzleberry is a really great option as the berries all together almost taste like a marionberry. .
Can you Use Frozen Berries in Marionberry Pie
Check the freezer section, sometimes there’s frozen marionberries or blackberry marionberries as some brands call them.
You can use an equal amount of frozen berries. There’s nothing to change and you don’t need to do any defrosting.
Blind or Unbaked Pie Crust
In the past, I have never blind baked a crust for a fruit pie, but I have started to recently and I am loving the results. Follow the instructions in our lemon meringue pie post for blind baking the bottom crust. Par bake the bottom crust, dock, bake with weights, remove the weights and bake a few more minutes. Then add the egg wash and bake a few more minutes to seal the crust. Let it cool before proceeding with the rest of the instructions for this pie. 
How to Make Marionberry Pie Filling
Making marionberry pie filling is one of the easiest pie recipes you’ll ever make.
- In a large pot over medium heat, add the berries and sprinkle in the remaining ingredients.
- Very gently fold the berries together just until they are coated and it begins to cook.
- Remove from heat and set aside.
Why is my Berry Pie Runny?
Your berry pie filling is runny because the liquids never set up. This can happen for a few reasons:
- Too Much Liquid from the Fruit
- Over-Ripe Berries Seeped too Much Excess Liquid In Baking
- Not Enough Thickener
- Not Long Enough in the Heat to Thicken
- Too Little Time Cooling to Set Up
- Wrong Kind of Thickener
How to Keep Your Fruit Pies from Being Runny
The trick to keep your fruit pies from being runny is using a good thickener.
- Flour
- Cornstarch
- Tapioca
- Cornaby’s Ultra Gel
All of these can act as a thickener in a fruit pie, but we actually only like one of them, Cornaby’s.
There’s no taste, no texture, just perfectly dreamy fruit pie filling.

How Much Flour to Use
If you cannot get Cornaby’s we suggest flour. You’ll use 1/3-1/2 cup depending on how juicy the berries are. Most pies seem to take 1/2 cup.
Marioberries are what dreams are made of! Put them in a marionberry pie and holy sweet mercy, take me now! Resistance is futile, and I might eat the whole pie!
