The easiest Triple Berry Crisp made with frozen raspberries, blueberries and blackberries for a juicy berry filling nestled under a crispy oat topping.
So it turns out that ya'll love fruit crisps just as much as I do! Some of my most popular dessert recipes are my BEST EVER Apple Crisp and my Peach Crisp, so I knew it was definitely time to share this delicious Berry Crisp with you all!
What I LOVE about this Berry Crisp:
- Frozen berries. For the filling, I use these big beautiful frozen berries from Costco's 3-berry pack in the frozen section. They are much cheaper than fresh berries and every bit as delicious. It also makes this recipe extra easy as it has the same flavors I love from my Triple Berry Pie, but it's much easier to make.
- Filling holds together. I've thickened the filling slightly so that it holds together and isn't a runny mess when you're serving it.
- That OAT crumble topping. The crumble on top is made with basic pantry ingredients (flour, sugar, oats, cinnamon, salt, and butter) and it bakes up all beautiful, golden and crisp.
Fresh or Frozen Berries:
You can use either fresh or frozen berries for this recipe, however, I'd actually recommend frozen berries. Large, good quality frozen berries. Frozen berries are cheaper and preserve nutrients in the berries at the time of freezing. I'd save those fresh berries for enjoying with some homemade granola or pancakes because you'll never notice the difference in this berry crisp.
How to Make Berry Crisp:
1. Make crumble topping: Combining the oats, flour, sugar, brown sugar, cinnamon and salt. Pour in the melted butter and stir to incorporate. Set aside.
2. Make berry filling. Combine frozen berries, flour, sugar, salt, lemon juice and vanilla extract.
3. Pour into dish. Then “glob” the topping ingredients evenly over the top (I say “glob” because the mixture will be softer than your normal dry crumble topping, because of the melted butter).
4. Bake for 40-45 minutes until the topping is golden brown and berries are bubbling around the edges.
5. Cool. Remove from the oven, place on a wire rack, and allow to cool for at least 7-10 minutes before serving. Serve with a scoop of vanilla ice cream, if desired. Cover leftovers and store in the refrigerator for up to 5 days.
MAKE AHEAD AND FREEZING INSTRUCTIONS:
To make ahead: Bake and cool the crisp completely, then cover it with a double layer of aluminum foil. I don't suggest preparing the crisp and storing it, unbaked, in the fridge because the topping will get soggy.
To freeze: Freeze for up to 3 months. Thaw overnight in the refrigerator, then warm in a 350°F oven for 20-25 minutes or until heated through.

Fantastic when I made it as instructed! The second time I tried to make it with a low fat “I can’t believe it’s not butter”. I do not recommend this as the texture and flavor were off. I will go back to using regular unsalted butter as the recipe states.
This was a huge hit at a family gathering. I followed recipe exactly using Publix Triple Berry frozen mix. Served with whipped non-dairy topping, as I forgot to get ice cream. This recipe is a keeper!

I love this recipe. First time I made it, it was perfect. Just made a second time. It is still delicious but the topping
was too crisp. What might I have done wrong?
This berry recipe was a hit!
I think there might be an error in the recipe. Just made it, and the topping is far, far too sweet. I love sugar, but it’s so sweet it’s almost inedible. Maybe should double the oats & add more cinnamon?
Hi, we are sorry the topping tasted too sweet for you, you can always cut down on the sugar to fit your personal preference.
That’s not an error on her part or with the recipe….that is a personal preference of how sweet you like desserts. Giving this two stars because of something YOU don’t prefer is asinine. The only error here is your lack of common sense.
I made this recipe this evening, and, OMG, it is so good. I used a fresh lemon for the juice, and used about two cups of mixed berries and blueberries for the rest. Delicious! I also cut back on the sugar, and, for health reasons, would like to omit even more next time. Do you have any suggestions as to the amount to use (for both the filling and the topping)? Thank you!
Hi Alyssa, I’m so happy you’ve liked the berry crisp!
You could try cutting the topping sugar down to 1/2 cup brown sugar (total). In the filling you could try cutting down to 2 tablespoons sugar.
I used the 2x recipe in a 9×13 glass baking dish. Turned out great! Also I only had sprouted oats and not old fashioned but they worked well in this recipe. I will be making this every summer!
My 7 year old daughter gave this 100 thumbs up! She said it’s even better than apple crisp!
Personally I loved how the tartness from the berries mixed with the sweetness of the crisp. We added a scoop of vanilla bean icecream.
Yum, Yum & Yum
So very easy to make
