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?
- Store the leftover berry pie recipe on the countertop, or in the refrigerator for a few days.
Freeze a berry pie?
- Freeze the pie baked or unbaked. Place the mixed berry pie in the freezer, uncovered at first, to help it set. Once frozen, wrap it with plastic wrap and double-wrap it in aluminum foil.
- To reheat. Thaw baked pie in the fridge overnight, or on the countertop at room temperature before serving.
- No need to thaw an unbaked pie. Pop it in the oven, checking to see if it needs a few more minutes at the end of the listed baking time. Frozen fruit pies should last about 4 months.
Would they’re be anything different I would need to do if I want to use frozen fruit instead of fresh?
Nope. You can just put them right in the recipe frozen.
Hi! I was going to make your triple berry pie for thanksgiving, quick question and so sorry to bother you, but do you need to pre-cook the crust? Thank you so much 💖
Oh I hope you enjoy the pie! Nope, you don’t need to pre-bake. You can put it in raw (both a homemade or premade crust will work), then add the filling on top with the oatmeal crumble.
