Finding a gluten free crust that is flakey and moist is one I found hard to find. So, I created my own gluten free pie crust, to fit exactly what I was hoping for when it came to the crust. Now, I use this crust recipe for all my pies. I think you guys will really appreciate the crust as much as we do.

This gluten free fruit pie is one I make when berry season hits in full swing. My family loves those brightly colored berries that are just bursting with sweetness. It is the ultimate dessert to whip up all summer long!

Ingredient notes:

Photos of the gluten free mixed berry pie ingredients.

Gluten free flour blend – I tested this recipe using Bob’s Red Mill 1 to 1 Gluten Free Flour Blend and King Arthur’s Measure for Measure Gluten Free Blend. That doesn’t mean others will not work; I just have not tested other flours.
If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add 1 teaspoon.
To make this recipe dairy-free, substitute the butter for cold vegan stick butter.
Tapioca starch – You can also use cornstarch to thicken the fruit sauce if you prefer.

Many use jello in their pie filling. This gluten free mixed berry pie recipe calls for a berry pie filling made without jello! I use tapioca or cornstarch to thicken this fruity berry pie filling.

Recipe step-by-step directions:

Step 1: Add your dry pie crust ingredients to a bowl. Whisk to blend them. Add in your cold butter and use a pastry blender to cut the butter into the dough. You can also use a food processor to do this, but be careful if you use it to not overgrind in your butter. You want your mixture to resemble crumbs.

Step 2: Mix the wet ingredients to form a dough. I know it is messy, but I do this step by hand to really mix it in. Mixing with a spoon can be misleading because the dough looks dry. Mixing with your hands incorporates the moisture better.

Step 3: Place half of the dough on a piece of wax paper dusted with a little gluten free flour. Cover with another piece of wax paper and roll to ¼ inch thickness. Remove the top piece of wax paper and place the dough side down over a greased pie tin. Peel off the remaining wax paper.

Step 4: Press the dough into the pie tin and pinch the dough around the edges using fingers on both hands.

Step 5: Add your washed berries to a large bowl. Be sure to pat them dry gently to remove extra moisture.

Step 6: Add the sugar and tapioca starch in a small bowl. Mix well.

Step 7: Pour the sugar starch mix over the fruit and mix well to coat all of the berries. Sprinkle the lemon juice over the fruit and mix.

Step 8: Gently pour the gluten free fruit pie filling into the bottom crust. Spread it out so that it is evenly placed.

Step 9: Roll out the remaining pie crust dough on wax paper. Roll to ¼ inch thickness. From here, you can place it over your pie completely or use cookie cutters to cut out shapes in the dough.

Step 10: If you are using the crust whole, be sure to poke a few holes in the top of the crust for steam to vent out. You can choose how much of your pie to cover if you use shapes like I did. I did not cover the entire top of my pie, and I used the extra dough to make two little mini handheld pies.

Brush the top of the pie crust with a beaten egg. You won’t use much egg; do not drench the crust, just a light egg brushing with a pastry brush. Cover the pie crust very loosely with foil.

Step 11: Bake the pie crust at 425º F for 10 minutes, then remove the foil and reduce the heat. ake at 375º F for an additional 35 minutes.

Tips and Recipe FAQ:

Can you use fresh or frozen berries?

I prefer to use fresh berries. I find it offers such a bold sweetness of fresh berries. In a pinch, you can use frozen berries. Just allow them to thaw and drain almost all the juice.

You will find frozen berries at their prime, so they will have a nice natural sweetness. The only thing is frozen berries will offer a bit of a different texture than a fresh strawberry.

How do you thicken mixed berry pie filling?

For me, I use tapioca starch as the thickener of the pie. It will help to make the liquid turn to a thicker texture, which is exactly what you want when you use tapioca starch. You can also use cornstarch.

Can you use different berries?

You can definitely use other berries if you would like. Raspberries, olallieberries, and even mulberries would taste amazing in this pie recipe. You can also use straight strawberries to make a strawberry pie.

Can you make this pie vegan?

Absolutely! You can reach for a vegan shortening to replace the butter in the recipe. It can alter the crust’s texture slightly, but you should have no problem whipping it up.

How long will this triple-berry pie keep fresh?

This pie will keep fresh in the refrigerator for up to 4 days in an airtight container.
