Blackberry Raspberry Pie {A Classic You’ll Be Obsessed With}

Raspberries and blackberries are the perfect summer fruit.  And to make the perfect blackberry-raspberry pie, you just need a few more ingredients to help them shine.  You can use frozen berries to make this any time of year, but it will always taste like summer.

Do not skip the chilling step, or your pie will be impossibly juicy!

  • Chill. Allow pie to cool to room temperature on cooling rack, then cover and refrigerator for 4-24 hours. Serve cold or room temperature.

Notes

Frozen berries work very well for this. Vanilla ice cream is the perfect complement.
Make sure not to overcook the filling.  You’re just allowing the berries to release juices and break down a bit, you aren’t making jam. 

❤️ Why you’ll love this recipe

Not too sweet. This is one of my husband’s favorite dessert recipes since it is not super sweet.  (His other most requested are key lime pie and plum cobbler, which both have a little tartness to them.)

Best for sweet tooths. If you like super sweet pies, you will want to increase the sugar in this recipe.  I start with the amount of 1 cup as a minimum, but once you’ve added that, be sure to taste the filling.  The natural sweetness of the berries will vary, as will your personal taste. If it doesn’t seem sweet enough, add another quarter cup or even half a cup of sugar.  If you like things a little tart, then one cup will probably be plenty for you.

Juicy treat. Even though berries and delicious and perfect for pies and cobblers, they are very juicy.  So we must try to correct this to avoid a mess when we cut into the pie. Two things help with this: cornstarch and cooling time. Mixing cornstarch into a little lemon juice and then stirring it into the berry mixture, the liquid in the berries will thicken.  This process continues as the pie cools and sets. You will need to cool the pie in the fridge for at least 4 hours but overnight is best.

🍴Instructions

Step One: Make the Crust

This recipe calls for a classic double pastry crust.  I like to use a recipe with a healthy amount of sugar in the dough.  My favorites are Ina Garten’s pie crust and the sweet pie crust recipe in this cookbook.  But any classic recipe with flour, butter or shortening, salt, and sugar will work well. If you aren’t comfortable with making your own pie crust, a store-bought one is fine. 

Either a lattice top or plain double crust will work.  Make sure you cut adequate slits in the top crust because you want all the steam out of the filling while the pie bakes. 

Some berry pie recipes use a graham cracker crust, but I don’t think it would hold up well with the juicy berries.  Stick with a pastry crust.

Step Two: Prepare a Pie Plate with Pie Crust

Prepare your pie pan with the pie crust and preheat the oven to 400 degrees.  You may want to place the pie plate on a foil-lined baking sheet to catch any drips and keep your oven clean. 

Step Three: Combine Berries and Sugar

The first step is to place 7 cups of berries in a large saucepan. You can do half of each type of berry or an uneven mix.  It depends on what you have and what you prefer. Mix in 1 cup of sugar, then heat the berries and sugar over medium heat for 5 minutes.  The berries will start to release their juices.

While this is happening, mix 2.5 tablespoons of lemon juice and 2 tablespoons of cornstarch.  Mix this into the berry and sugar mixture and gently stir it. Let it simmer for 1 minute, then remove the pan from the heat.

Step Four: Bake and Let it Cool

Bake for 40-45 minutes, until the filling is bubbling and the crust is golden brown.  But halfway through, check to see if the crust is browning too quickly. If it is, shield it with some aluminum foil.  (Or get a pie shield if you bake a lot.)

And it is very, VERY important to let this cool completely, AT LEAST four hours, as we have already discussed.  That’s a good thing! Make it the day before a special dinner and the next day, it’s already done.  

🥫 Storage instructions

The best way to store blackberry-raspberry pie is to wrap it up with plastic wrap and place it in a ziplock bag before storing it in the refrigerator for 3-4 days..

🔍 FAQs

Can I use frozen berries for this recipe?

Yes, you can still use frozen berries and they will taste the same.

Is black raspberry the same as blackberry?

No. Even though they look very similar, black raspberries and blackberries are two completely different fruits. To tell them apart, look for the telltale hole in the bottom. Black raspberries have a hollow core, while blackberries are solid

👩🏻‍🍳 Expert tips

  • Coarse sugar that will hold its shape in the oven gives the crust a yummy sweetness and crunch
  • A pie shield is handy to keep the crust from over-browning
  • You’ll need a pastry wheel to cut the crust if you want pretty lattice strips.

A few years ago, we planted an apple orchard and a berry patch with rows of blackberries and raspberries.  We have little to no luck with the apples, but we are lucky enough to harvest quarts of fresh berries every summer.  There is always a period of overlap between them in June, and again in September. And when that happens, we make this homemade pie.

  1. hello–i am going to try this recipe today…one thing i could not find in the instructions was the oven temperature recommended. i will use a berry pie temp from the ‘better home’ ‘cookbook (375 degrees) today, fingers crossed
    thanks

  2. 5 stars
    I just made this with freshly picked wild raspberries (no blackberries) and it is delicious!! I am an experienced baker but by no means a pro at pies. I would recommend draining any excess water from freshly washed or thawed frozen berries and using one’s own judgement on the cooking times needed for proper thickening based on what you are seeing in the pot. Also recommend adhering to the instructions as to amount of time to let the pie set.

    This recipe did not work out well for me. BUT, to be fair, this is my very first berry pie, and really only my third pie ever.

    Cooking the berries first made them too juicy, which is what I was afraid of, but wanted to try anyway, because Im in experiment mode. Obviously, it works for others, so I wanted a hand at it too, but by the time the pie was done and cooled, i had a very tart soup…which is not an exaggeration. Even now, the next day, its still drinkable, which is weird because anything left in the pan when i warmed up the berries set up nicely. Im going to try a different oven, and maybe a lot more cornstarch.

    I think the tartness was as strong because store bought berries are hard to find ripe and the right kind of sweet, so the lemon juice kinda made it worse. Im trying to avoid adding MORE sugar.

    Honestly, im still picking at it so it didnt turn out bad, but im going to be doing a bit more research and delicious practicing to figure this out, and I will still have this recipe bookmarked to try again!

    1. hey jess! a few things i thinkk will help you next time… 1. get frozen berries. they are sweeter and better than fresh at the store this time of year because thy aren’t varieties bred to stay hard and “shippable”. 2. DO NOT cut the pie until the chilling period mentioned at the end of the recipe. like….EVER. it really needs to cool to set. almost like jello. it’s not optional. and make sure you aren’t overcooking the berries in step 1, it’s just for five minutes until they get slightly juicy. hope this helps and good luck!! 😊

        Thanks for the tips!! I def think my major problem was cooking the berries too long in step one. I altered it according to your suggestions and it worked wonders. I did one fresh and one frozen and they came out relatively the same. Now my family wont stop asking me for more pie (a very good problem to have)!

  4. Do you think it helps to pre bake the pie crust for 10 or 15 minutes before adding the fruit filling? Just worried the crust won’t cook enough and will be gummy given how wet the filling is.

    If your cookdown of fresh berries is too juicy, you may need additional cornstarch. Also, you may want to hold back some of the berry juice when you fill the pie shell prior to baking. As the pie cools, it should thicken appreciably. My first one did. This is my second and it remains to be seen after it has cooled. More of it overflowed during baking this time, but I don’t see that as a spoiler. BTW, I’m using a gluten free shell (last time I used a cauliflower shell from “Sprouts” which was delicious). I use CocoWhip whipped coconut topping rather than the suggested vanilla ice cream to keep the sugar down.

  6. Just wondered if I could use frozen berries in would it be possible to use frozen blackberries and raspberries in this recipe??

  7. Looks yummy! We are not yet in surplus with the berries, I only planted them last year. Just enough to eat. Hoping for a big harvest in a few years!
