You just can’t beat this easy and delicious homemade Triple Berry Pie! It holds together perfectly every single time, and you can use fresh or frozen blueberries, raspberries and blackberries.
If you’ve tried any of my other favorite pie recipes, you may have learned that I’m a Pie fanatic! It’s the most important part of my Thanksgiving. Don’t miss my classic Pumpkin Pie, Apple Pie, and Lemon Meringue pies.
On Thanksgiving, I take great care not to over-stuff myself during dinner so that I have plenty of room for pie. And no, I don’t just pick one favorite and enjoy a slice. I request slivers of nearly every single kind of pie (which, growing up, meant like 15-20 different kinds!).
My Mom mastered this Triple Berry Pie years ago. It’s always the first gone at Thanksgiving–even for my husband who usually detests berries with seeds in them.
This pie is restaurant quality! Scratch that. It’s BETTER than restaurant quality, because it’s made from scratch! The crust is my Grandma’s “Prize Winning” pie crust recipe, which couldn’t be easier to make.
For the filling, I use the big beautiful frozen berries from Costco. They come in a 3-berry pack in the frozen section and the price is unbeatable. They are the biggest, nicest frozen berries I’ve ever seen. Don’t you just love Costco?!
How to Make Perfect Berry Pie:
Cook berries: Simmer berries, sugar and lemon juice in a large saucepan over medium heat until warm and juicy, about 5-10 minutes, gently stirring occasionally.
Thicken filling: Spoon out about ½ cup of the juice from the pan into a bowl. Stir cornstarch into the juice until smooth. Bring pot of berries back to a simmer and slowly pour in the cornstarch. Gently stir mixture (being careful not to mash the berries), until thickened, about 2-5 minutes.
Cool. Remove from heat and stir in the butter. Allow to cool for 15 minutes.
Add to pie shell: Pour mixture into unbaked pie shell (in a 9 in deep dish pan). Add lattice top or a whole top with holes pricked on top for steam to escape. Pinch the edges of the top and bottom pie crusts together and crimp the edge, if you like.
Brush with egg wash: Brush a thin layer of beaten egg white over the top of the pie and sprinkle lightly with sugar.
Bake at 400 degrees F for 40-45 minutes. Check it after about 25 minutes and place a piece of tinfoil over it if the top crust is getting too browned.
Serve or refrigerate. Remove to a wire cooling rack and allow to cool for several hours. Once cooled completely, you can cut into it or cover it and refrigerate it overnight to serve the next day.
What sets this Berry Pie apart?
- Less sugar. It has way less sugar than most berry pies. It’s still amazingly sweet, but it’s not overly sweet, like some berry pies tend to be.
- Holds it’s shape. It has the perfect amount of liquid to yield a pie slice that holds its shape. Some berry pies are so juicy that they completely fall apart when you cut into them. This one will turn out beautifully, as long as you let it cool for several hours before cutting into it.
So there you have it. Our family’s favorite Triple Berry Pie. Perfect for Thanksgiving or Christmas or any time you’re craving some pie…which, for me, is ALWAYS.
How to Make a Lattice Crust:
Don’t let this beautiful pie crust intimidate you! It’s so easy, especially if you know the tricks!
- Roll out crust. Roll our your homemade crust on a lightly floured counter or on a piece of parchment paper. (I like to place a piece of parchment paper on top of a damp kitchen towel to keep it from moving around). Roll the pie crust into a large circle that’s about 1-2 inches larger than then top edge of your pie dish.
- Cut strips. Use a pizza cutter to strips. cut them as wide as you’d like them to be (there’s really no right or wrong way).
- Lay first layer of strips. Lay your longest strip across the middle of the pie then lay a few shorter strips on either side, parallel to each other and spaced evenly.
- Fold pack even numbered strips. Fold back the second and 4th strip and lay a shorter strip of dough perpendicular to other dough strips. Unfold those dough strips over the new strip.
- Fold back odd numbered strips: Fold back the first, third and fifth strips in the same direction and lay another dough strip across the pie. Unfold the first, third and fifth strips over the new strip.
- Repeat steps 4 and 5 until pie is covered with a lattice crust.
- Trim dough strips.
- Pinch crusts together. Pinch the lattice top with the bottom crust to form one unified outer edge.
- Crimp edges.
Make Ahead and Freezing Berry Pie:
To make ahead: This pie can be prepared completely 1 day a head of time. You can also prepare the filling up to 3 months ahead of time and store it in the freezer. Thaw it overnight in the refrigerator before pouring in unbaked pie crust.
To freeze: You can freeze the baked pie for up to 3 months. Thaw overnight in the refrigerator and allow to come to room temperature before serving.

Recipe

Triple Berry Pie
Equipment
Ingredients

- 7 cups fresh or frozen raspberries, blueberries and blackberries about 2 ⅓ cups of each type of berry*
- 1 cup granulated sugar (plus a little extra to sprinkle on top of the pie)
- 1 Tablespoon lemon juice
- 4 Tablespoons cornstarch
- 2 Tablespoons butter
- 1 large egg white beaten with a fork
Instructions
- Cook berries: Add berries, sugar and lemon juice to a large saucepan over medium heat.
- Simmer, until warm and juicy, about 5-10 minutes, gently stirring occasionally. (You can taste it at this point and see if it's sweet enough for your liking. I don't like to make mine too sweet, but if you want it sweeter you can add ¼ cup more sugar.)
- Thicken filling: Spoon out about ½ cup of the juice from the pan into a bowl. Stir cornstarch into the juice until smooth.
- Bring pot of berries back to a simmer and slowly pour in the cornstarch. Gently stir mixture (being careful not to mash the berries), until thickened, about 2-5 minutes.
- Cool and add to pie shell. Remove from heat and stir in the butter. Allow to cool for 15 minutes. Pour mixture into unbaked pie shell (in a 9 in deep dish pan).
- Add lattice top or a whole top with holes pricked on top for steam to escape. (See directions for lattice crust below).
- Pinch the edges of the top and bottom pie crusts together and crimp the edge, if you like. Brush a thin layer of beaten egg white over the top of the pie and sprinkle lightly with sugar.

I made this for a dinner we went to. It was a hit. It was the perfect consistency. I’ve tried this before but it was too runny. Will definitely make this again.
How long is the filling good for in the fridge? I made too much last week and put it in an airtight container, not sure if it’s still good to use. Also- best pie ever!!!! Comes out perfectly. Very forgiving recipe , thank you!
A good rule of thumb is usually 4-5 days in the fridge. It could still be fine, just smell it and check for any signs of mold. If you aren’t planning on making it again soon, we suggest freezing the filling then letting it thaw before using. We are so glad you love it, it’s a favorite of mine too!
The flavor was great but the consistency was so runny. It seemed thick during the cornstarch phase, I read others had the same problem so I even added more cornstarch but it still didn’t hold after hours of chilling.
It’s my first time making this pie. I’ve had success with apple, pecan, pumpkin, and key lime pies. I followed the recipe exactly but mine came out as berry soup. I used the frozen bag from Costco and it definitely took longer to cook the berries. I also had no idea how to measure 7 cups of frozen clumps of berries so I ended up using fluid ounces—which amounted to nearly the entire Costco bag. It was completely awful.
Hi Rita, I’m sorry it didn’t work the first time but hope you get to try again. Measure the berries in a dry measuring cup, just filling in the gaps as best you can until it’s level. It will be around 2 lbs. It does sound like too many berries were used (if you used a whole 4lb bag from cCstco), which means the sauce was extra juicy and would have needed more cornstarch slurry to thicken it, before adding it to the pie. The berry pie filling must be thickened before it goes in the oven (that way you know it wont end up as soup). If it’s not thickening enough on the stove just add a little more cornstarch slurry.
I’ve tried making this 3 times, mostly because the picture looks amazing. But every time, it turns into the melted mess of dough and berry juice. Put the filling in the freezer for 20 mins to see if that helps but the lattice just dissolves into it. How in the world do you do it?
Are you cooking the filling until it is thick? It should be thickened, and cooled, before it goes into the pie crust. The pie crust also needs to be cold! That should solve the problem 🙂
Have made this pie filling with my own preferred crust for a few years now, always amazing, but I was short on berries so I put in 2 1/2 C peaches I’d frozen from the summer. And it is DELICIOUS!!
do I need to thaw the berries first or just put them straight from the freezer into the pot??
Add them frozen!
