The easiest Triple Berry Crisp made with frozen berries 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 recipes are my BEST EVER Apple Crisp and my Peach Crisp, so I knew it was definitely time to share this delicious Triple Berry Crisp with you all! It would be perfect for Thanksgiving dessert, since it’s just as tasty as pie but a lot easier and less time consuming to make.
For the filling, I use these big beautiful frozen berries you see above. They’re the 3-berry pack in the frozen section at Costco and the price is unbeatable. They are the biggest, nicest frozen berries I’ve ever seen.
I love how easy fruit crisps are to make. This one has the same flavors I love from my Triple Berry Pie, but it’s even easier to make. Perfect for any type of baker, even the most amateur. I’ve thickened the filling slightly so that it holds together and isn’t a runny mess when you’re serving it. The oat crumble on top is insanely delicious. It bakes up all beautiful, golden and crispy and is the perfect contrast to the sweet, juicy, warm berries. It’s perfect for serving a crowd, especially with a scoop of vanilla ice cream! See the notes below the recipe for tips on making this ahead of time or freezing it.
- 1 cup old-fashioned oats
- 1 cup flour
- 1/4 cup granulated sugar
- 3/4 cup brown sugar
- 1 tsp ground cinnamon
- dash salt
- 2/3 cup unsalted butter, melted
- 4 1/2 cups frozen berries** (raspberries, blackberries and blueberries)
- 1/4 cup all-purpose flour
- 1/4 cup granulated sugar
- 1/4 teaspoon salt
- 1/2 teaspoon lemon juice
- 1 teaspoon vanilla extract
- Preheat oven to 350 degrees F.
- Make the topping first by combining the oats, flour, sugar, brown sugar, cinnamon and salt. Stir to combine. Pour in the melted butter and stir to incorporate. Set aside.
- In another bowl add the frozen berries, flour, sugar, salt, lemon juice and vanilla extract and toss gently to combine. Pour mixture into an 8x8’’ or similar size casserole dish or pie plate. 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).
- Bake for 40-45 minutes until the topping is golden brown and berries are bubbling around the edges. 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.
- I don't suggest preparing the crisp and storing it, unbaked, in the fridge because the topping will get soggy.
*I use the Costco, Kirkland brand of frozen berries called “Three Berry Blend” that includes blueberries, blackberries and raspberries.
*You can use fresh berries, but you may need to cut down on the baking time by at least 5 minutes.
