How to Make Triple Berry Crisp
Preparing the Berry Filling
Start by preheating your oven to 350°F (175°C) and spraying your baking pan with nonstick spray. In a large bowl, combine the frozen mixed berries, cornstarch, lime juice, and 3 tablespoons of sugar. Stir gently until the cornstarch is evenly coated on the berries. Pour this luscious mixture into the prepared baking dish, ensuring every bit of sugary goodness finds its way into the pan.
Making the Oat Topping
In another bowl, mix the quick-cooking oats, old-fashioned oats, ¼ cup + 2 tablespoons of sugar, brown sugar, and kosher salt. Now, add the cold butter pieces to this oat mixture. Using your hands or a pastry blender, cut the butter into the oats until it resembles a crumbly mixture that will create the perfect topping.
Assembling and Baking the Crisp
Generously sprinkle the oat mixture over the berry filling in the baking dish. Bake on the middle rack for 55 to 60 minutes, or until you see the berries bubbling and the topping turns a beautiful golden brown. If the topping browns too quickly, cover it with aluminum foil and continue baking until done.
Tips for the Perfect Crisp Topping
For an extra crunch, consider adding chopped nuts like walnuts or pecans to the topping. If you want to make this dessert gluten-free, simply use certified gluten-free oats. It’s a fantastic way to accommodate dietary needs while still enjoying a delicious dessert!
Variations and Substitutions for Triple Berry Crisp
If you’re in the mood for a twist, feel free to use fresh berries instead of frozen ones, or swap out the lime juice for lemon juice. You can also make this dessert dairy-free by replacing the butter with coconut oil. The possibilities are endless!

How to Store Leftover Crisp
Once you have finished enjoying your triple berry crisp, store any leftovers in plastic wrap in the refrigerator for up to a week. The flavors will continue to meld beautifully!
