Triple berry pie might just become your new favorite dessert. It’s fresh, fruity, and perfect for any season, be it summer or fall – or any time of the year!
Instead of going for a traditional lattice topping, we went with a chunky crumb topping. we love how it transformed the pie into a bit of a cobbler recipe – two of our favorite desserts in one!
Why we love it:
- Simple filling. This easy-to-make minimalist filling allows the sweet and tart flavors of the berries to shine.
- Freeze for later. Fruit pies freeze very well for convenient storage and reheating, enjoy fresh berries all year long!
- A tasty twist. Fresh berry pie is a cross between a Blueberry Cobbler and a pie. The chunky crumb topping adds a delightful crunch.

Recipe FAQ
Can I use a pie crust for the top?
- To top with a pie crust, roll out a 10-12 inch round.
- Either use a solid top crust with venting slits or cut the dough into strips and weave them together for a lattice topping.
- Use a shaped cookie cutter and stamp out pieces from the pie crust. Spread the shapes on top of the berries and bake. A star-shaped cookie cutter would be especially fun for the Fourth of July.
How can I tell when the pie is done?
- The filling should be bubbling throughout the center and around the edges. This indicates the filling has reached a good temperature and thickened properly.
- The crumble topping should be golden brown and crisp throughout.
- Line a baking sheet with foil, and place it on the bottom rack while the oven is preheating. If the filling bubbles over, it will land on the baking sheet instead of making a mess on the bottom of the oven.
How to store a berry pie?

This was delicious! I used blackberries and raspberries and it turned out great!
Ooh so yummy! Glad to hear you enjoyed it!
This pie is my new favorite pie! No blackberries at the store the first time I made it so I subbed in strawberries and it was just divine! Making again today but with blackberries for my daughter’s birthday (requested b/c the first pie was sooo good). Thank you!
Can i make the pie ahead of time? how do i store the pie, in the refrigerator or out on the counter?
If I were making it the morning of, I would just leave it on the counter. If I were making a day before, I would do everything until the baking step & stick in the fridge & bake before eating.
Hi! Do you mean to put the top crumble all into a pastry blender with the butter until pea size lll form or just the butter?
The first one you said…. so mix the other ingredients for the crumble, then cut in the butter with those ingredients. 🙂
Most amazing pie! I made it for a dinner party and even though all the guests were stuffed from dinner, they ate every last bite of their slice of pie! I topped each slice with a scoop of Vanilla ice cream. So Delicious!
Yay!! You can’t turn away dessert! Glad everyone liked it! Thank you!
Absolutely delicious!!! We used blueberries, strawberries, and raspberries in our recipe. As soon as we Pinned this recipe and saw it was lilluna.com, we knew it was going to be A delicious recipe! We love your chocolate chIp cookies too!
Awe, that’s so nice! Thank you so much for saying that!
This was Really good and so Simple! My four year old had a blast making and eating it 🙂
Making this was a last minute decision and we only had margarine. if you’re not using real butter, definitely watch that you don’t over-mix and/or pop the margarine in the freezer for a bit beforehand.
Also, we used frozen berries (thawed) with no issue 🙂
So glad! Thank you for sharing that!
THIS RECIPE IS A KEEPER. nOT TOO SWEET NOR TOO TART. gOING INTO MY ‘FAVORITE RECIPES.’
Thank you for sharing that! I am happy that you liked it!
So far so good but in the dirsct im a little confUsed it said to cover with foil back 25-30 min then at the 45 mark tent the foil so topping does not get to dark so after the 25-30 minutes am i su to tent the foil and bake an additional 45 min?
This is a contributors recipe, but you would bake it for 30 minutes, then cover with 20-25 minutes, so that’s a total of about 50-55 minutes. She is saying to tent the foil at the 45 minute mark, to prevent browning. I hope that makes sense. Let me know if you have any more questions.
Delicious
