Ingredients You’ll Need
- ¾ cup (93g) all purpose flour: This gives structure to your crumble. You could substitute with gluten-free flour for a gluten-free option.
- ¾ cup (64g) quick cook oats: They add a nice texture and chew to the topping, enhancing the crispness.
- ¾ cup (150g) packed brown sugar: Adds a rich sweetness and depth of flavor. You can replace it with coconut sugar for a healthier alternative.
- 1 teaspoon cinnamon: This gives a warm, aromatic flavor that lies beautifully underneath the fruit.
- 6 tablespoons (78g) cold unsalted butter, diced: Cold butter is essential for creating that perfect crumb. Use vegan butter if you prefer a dairy-free version.
- ¼ teaspoon salt: Elevates all the flavors without making it taste salty.
- 1 pound strawberries, hulled and sliced: Juicy strawberries provide a fresh and tangy taste. Feel free to use frozen strawberries if fresh aren’t available.
- 2 cups blueberries, frozen or fresh: They add a burst of sweetness and color; frozen blueberries work wonderfully here too.
- ½ cup (50g) granulated sugar: Balances the tartness of the berries; adjust this based on your sweetness preference.
- 1 tablespoon lemon juice: Brightens the flavors and complements the berries perfectly.
- 3 tablespoons (24g) cornstarch: Thickens the berry filling, ensuring it doesn’t become too runny.
How to Make Mixed Berry Crisp
- Preheat your oven: Set it to 350°F (175°C) to ensure a perfectly baked crisp.
- Make the crumble: In a large bowl, combine ¾ cup all-purpose flour, ¾ cup brown sugar, ¾ cup quick cook oats, 1 teaspoon cinnamon, and ¼ teaspoon salt. Use a pastry cutter to cut in 6 tablespoons of cold unsalted butter until the mixture resembles small crumbs. Getting in there with your hands can help if needed! Set this mixture aside.
- Prepare the berry filling: In another large bowl, toss together 1 pound of hulled and sliced strawberries, 2 cups of blueberries, ½ cup granulated sugar, 1 tablespoon lemon juice, and 3 tablespoons cornstarch gently until the berries are all coated and the sugar starts to dissolve. Transfer this luscious mixture into the bottom of an 8-inch square pan, spreading it evenly.
- Assemble the crisp: Pour the crumble mixture over the berry filling, pressing down gently to compact it slightly for that perfect texture.
- Bake to perfection: Place the pan in the oven and bake for 30-33 minutes, or until the topping is golden brown and the edges are bubbling. Once done, allow it to cool slightly before serving—this step is crucial because the filling will thicken further as it cools.
Storing & Reheating
To keep your Mixed Berry Crisp fresh, store it at room temperature for up to 2 days. If you have leftovers, place them in an airtight container in the refrigerator for up to a week. You can also freeze it for up to 3 months; simply cover it well and let it cool before wrapping. When you’re ready to enjoy it again, reheat in a 350°F (175°C) oven for about 20 minutes, or until warmed through. Just note that the topping may soften a bit, but a quick broil for the last few minutes can help refresh that crunchy texture.
Chef’s Helpful Tips
- Don’t skip cooling: Allowing the crisp to cool helps the filling thicken and prevents it from spilling in the pan when served.
- Room temperature ingredients: If you decide to substitute the butter, ensure it’s still cold; this helps achieve the desired crumbly texture in your topping.
- Mixed berries: Feel free to experiment with other fruits like raspberries, blackberries, or even peaches for a different twist on the classic.
- Sweetness adjustment: Taste your berries before mixing in the sugar; depending on their ripeness, you may want to adjust the sugar accordingly.
- Make-ahead option: Prepare the berry filling and crumble topping separately in advance. Store in the fridge and assemble just before baking for ultimate freshness.
Mixed Berry Crisp is not just a dessert; it’s a warm hug on a plate that reminds you of summer. The way the sweet, tangy berries mingle with the crunchy topping is sheer bliss. Don’t hesitate to get creative too—try adding your favorite nuts or a sprinkle of coconut to the topping! Share this treat with friends and family, and enjoy the comforting warmth and flavor that this delightful dessert brings. It’s a must-try that’s sure to become a staple in your kitchen.

Recipe FAQs
Can I use frozen berries?
Absolutely! Frozen berries work beautifully in this recipe. Just ensure they’re thawed and drained of excess liquid before mixing with the sugar and cornstarch. This will keep the filling from becoming too watery.
How can I make it gluten-free?
To make this Mixed Berry Crisp gluten-free, simply swap the all-purpose flour for a gluten-free flour blend and ensure your oats are certified gluten-free. The rest of the ingredients are already naturally gluten-free.
What if I don’t have brown sugar?
If you’re out of brown sugar, you can use granulated sugar with a tablespoon of molasses for that caramel flavor. Alternatively, coconut sugar makes a great substitute for a healthier option.
Can I prepare it ahead of time?
Yes! You can prepare the filling and crumble topping ahead of time. Simply store them separately in the refrigerator and assemble them just before baking for the freshest taste.
