5 tablespoons cold butter, plus more for coating the dish
4 cups frozen mixed berries
1 tablespoon lemon juice
1/4 cup sugar
4 tablespoons flour, divided use
1 cup rolled oats
1/4 cup chopped pistachios
1/3 cup brown sugar
1/4 teaspoon salt
1/4 teaspoon ground cinnamon
1. Preheat oven to 350 degrees. Lightly coat a 9-inch pie dish or oven-safe skillet with butter.
2. In a large bowl, add berries, then sprinkle lemon juice over the top. Combine sugar and 2 tablespoons flour and sprinkle over berries; mix well. Pour into the prepared pan.
3. In a small bowl, combine oats, pistachios, brown sugar, remaining 2 tablespoons flour, salt and cinnamon. Cut in butter using a pastry blender or two forks until large clumps are formed and no dry bits remain. Sprinkle topping evenly over fruit mixture.
4. Bake 45–50 minutes, until browned and bubbly.
