This mixed berry crisp is the ultimate summer dessert. You can make it with strawberries, blueberries, raspberries, blackberries—or any combination of your favorite berries. It’s topped with a crispy oat and nut crumble and best served warm with a scoop of vanilla ice cream.

Berry Crisp Highlights: What Makes It Special
- One-skillet wonder: I baked this in a 13-inch cast iron skillet, so it’s easy to prep, bake, and serve all in one pan—no extra dishes needed. I highly recommend using a cast iron skillet: Not only does it go from oven to table beautifully, it also helps caramelize the fruit and gives the topping extra crunch.
- Crunchy oat-nut topping: I made the topping with old-fashioned rolled oats, almonds, and pecans for great texture and nutty crunch. A little cinnamon adds a nice touch!
- Lemon juice and zest adds even more freshness to the mixed berry filling and bring out the natural sweetness of the berries. (You can also use orange!)
- Naturally sweetened: Instead of refined sugar in the filling, I used maple syrup (honey works, too!) for a more wholesome, naturally sweet flavor.
- Totally customizable: You can use any mix of berries (raspberries and blackberries work great!). And it’s easy to make it gluten-free with GF oats and brown rice flour, almond, or any other GF flour. Love crisps? Try my blueberry peach crisp next!


How to Make Berry Crisp (Step-by-Step)
- First, gather all your ingredients; and, preheat your oven to 375°F (190°C). Here’s a photo showing everything you’ll need:

- Make oat-nut topping: Stir together the oats, flour, brown or coconut sugar, cinnamon, and salt. Pour in the melted butter and mix until crumbly. Fold in the sliced almonds and chopped pecans.

- Make a fruit filling: In a 13-inch cast iron skillet, gently mix the strawberries and blueberries with lemon zest, juice, maple syrup (or honey), and cornstarch. Spread the mixture out evenly in the skillet.

- Assemble and bake: Sprinkle the topping evenly over the fruit. Bake for 30–35 minutes, or until the topping is golden and the fruit is bubbling.

- Cool and serve: Let the crisp cool for about 10 minutes before serving. Serve warm with a scoop of vanilla ice cream, whipped cream, or a dollop of yogurt.

Baking a Better Crisp: Simple Tips
- Balance fruit sweetness and tartness: I recommend combining sweeter fruits (like peaches or strawberries) with tarter ones (like raspberries, blackberries, or rhubarb) to create balanced flavor.
- Keep the topping crumbly: Don’t overmix the oat topping—just stir until it forms large, crumbly clusters. These bake into the best crunchy bits!
- Use the right fat: Butter gives the topping rich flavor, but you can also use coconut oil or plant-based butter for a dairy-free option.
- Watch your ratios: You want a good balance of fruit to topping—too much topping and the crisp overwhelms the fruit; too little and you lose that golden crunch.
- Add texture with nuts or seeds: Almonds, pecans, walnuts, or even sunflower seeds add great crunch and pair well with most fruits.
- Reheat leftovers in the oven: A quick 10-minute reheat at 350°F revives the topping’s crispiness—much better than the microwave!
Storage & Reheating Tips
- Room temperature: If you plan to eat it within a day, you can loosely cover the berry crisp with foil or plastic wrap and leave it at room temp for up to 24 hours.
- Refrigerator: For longer storage, cover and refrigerate for up to 4 days. The topping may soften slightly, but it still tastes great.
- Freezer: You can freeze the baked crisp (cooled completely) for up to 2 months. Wrap tightly in plastic wrap and foil, or store in an airtight container. Thaw overnight in the fridge before reheating.
- Oven: Reheat at 350°F (175°C) for about 15–20 minutes to help re-crisp the topping.
- Microwave: Quick individual servings can be warmed in the microwave, though the topping will be softer.

Mixed Berry Crisp
This mixed berry crisp is the ultimate summer dessert. You can make it with strawberries, blueberries, raspberries, blackberries—or any combination of your favorite berries. It’s topped with a crispy oat and nut crumble and best served warm with a scoop of vanilla ice cream.
Ingredients
For the Fruit Filling:
- 5 cups strawberries (600 g), hulled and halved (or quartered if large)
- 2 cups blueberries (300 g)
- 1 large lemon juice and zest
- ¼ cup maple syrup (60 ml) or honey
- 1 tablespoon cornstarch (8 g)
For the Oat-Nut Crisp Topping:
- 1 cup old-fashioned rolled oats (100 g)
- ½ cup all-purpose flour (60 g)
- ⅓ cup packed brown sugar (65 g) or coconut sugar
- 1 teaspoon cinnamon (2 g)
- ¼ teaspoon salt (1 g)
- ½ cup unsalted butter (113 g), melted
- ⅓ cup sliced almonds (30 g)
- ⅓ cup chopped pecans (40 g)
Instructions
- Preheat the oven to 375°F (190°C)
- Prepare the fruit filling: gently toss the strawberries and blueberries with lemon juice, lemon zest, maple syrup (or honey), and cornstarch in a 13 inch cast iron skillet. Spread evenly.
- Make the oat-nut topping: In a medium bowl, combine rolled oats, flour, coconut or brown sugar, cinnamon, and salt. Stir in the melted butter until the mixture becomes crumbly. Fold in the sliced almonds and chopped pecans.
- Assemble & bake: Evenly sprinkle the oat-nut topping over the fruit mixture. Bake for 30-35 minutes, or until the topping is golden brown and the fruit is bubbling.
- Cool & serve: Let the crisp rest for 10 minutes before serving. Enjoy warm with vanilla ice cream, whipped cream, or yogurt.
Notes
- For a gluten free version use gluten free oats and GF flour.
- To make this crisp dairy-free, simply replace the butter in the topping with an equal amount of coconut oil or a plant-based butter alternative.
- You can substitute lemon juice and zest for orange.
- Keep the right balance between fruit and topping: too much topping can overpower the fruit, while too little means missing out on that perfect crunchy layer.
- Storage: Keep the crisp covered at room temp for up to 24 hours or refrigerate for up to 4 days (topping may soften). Freeze cooled crisp tightly wrapped for up to 2 months; thaw overnight before reheating.
- Reheating: Reheat in a 350°F oven for 15–20 minutes to crisp the topping. You can also use a microwave, but the topping will be softer.

I love everything nuts so this was right up my alley! Actually had some pecans that were nearing the expiration date so it worked perfectly. Thank you for inspiration...
Thanks, Lynn, for your 5-star review! 🙂 Glad you loved this nut-packed version of berry crisp as much as I did. 🙂
