I enjoy preparing this Mixed Berry Crisp because it combines succulent strawberries, tangy blueberries and sweet blackberries with a splash of lemon juice and granulated sugar. The topping, made with rolled oats, brown sugar and unsalted butter, creates a delightful contrast that never fails to catch my attention.
I’ve been experimenting in the kitchen lately and came up with this Mixed Berry Crisp that quickly became a new favorite. Recently, I decided to toss together 2 cups strawberries, 1 cup blueberries and 1 cup blackberries with 1/2 cup granulated sugar, a splash of 2 tablespoons lemon juice and 2 tablespoons cornstarch.
This combo really creates a burst of flavor while keeping things simple. For the crunchy topping i mix 1/2 cup all-purpose flour, 1/2 cup rolled oats, 1/3 cup brown sugar, 1/4 teaspoon salt and 1/4 cup unsalted butter diced into little bits.
It reminds me of some of the frozen mixed berry recipes out there as well as other versions like berry dessert classics and even mixed berry parfaits that I’ve seen. It’s a quick, easy, and definite crowd pleaser recipe that you just have to try out.
Enjoy the burst of real berry flavor!

FAQ
Mixed Berry Crisp Recipe Substitutions and Variations
- If you dont have lemon juice, you can use lime juice instead. They both give that tangy kick
- You can swap out the cornstarch for arrowroot powder in equal amounts if its what you have
- Use almond flour instead of all-purpose flour for a nuttier flavor, but the texture might change a bit
- Quick oats can be used in place of rolled oats if you’re in a pinch, just use the same amount
- If you dont have unsalted butter, coconut oil works well as a substitute. Melt it first then mix in
Pro Tips
1. Let the fruit mixture sit for about 10 mins before you put it in the oven so the flavors can really mix together, it’s a tiny trick that makes a big difference.
2. When you mix the butter into the dry ingredients, work quickly and gently with your fingers or a pastry cutter so you dont end up with an overworked, tough topping.
3. Start checking your crisp around 5 mins before the recommended bake time; every oven is a bit different and you dont wanna overbake it.
4. Let the crisp cool for a few minutes after you take it out of the oven; it helps the filling thicken up and makes serving it way easier.
