Ingredients :

• 6 cups mixed berries (blueberries, raspberries, and blackberries)
• 1/2 cup granulated sugar
• 1 tablespoon lemon juice
• 2 tablespoons cornstarch
• 1 cup old-fashioned rolled oats
• 1 cup all-purpose flour
• 3/4 cup packed light brown sugar
• 1 teaspoon ground cinnamon
• 1/2 cup cold unsalted butter, cubed
• 1/4 teaspoon salt

Method :

1. Preheat your oven to 375°F (190°C) and lightly grease a 9-inch square baking dish.
2. In a large mixing bowl, toss the mixed berries with granulated sugar, lemon juice, and cornstarch until evenly coated.
3. Transfer the berry mixture into the prepared baking dish and spread it into an even layer.
4. In a separate bowl, whisk together the oats, flour, brown sugar, cinnamon, and salt.
5. Add the cold cubed butter to the oat mixture and use a pastry cutter or your fingers to work it in until crumbly.
6. Sprinkle the oat topping evenly over the berries in the baking dish.
7. Bake for 35 minutes until the topping is golden brown and the berry juices are bubbling.
8. Allow the crumble to cool for at least 10 minutes before serving to let the sauce thicken.

Recipe Notes :

Chef Pro Tip: Use very cold butter to ensure the topping stays crispy rather than melting into the fruit. Variation: Add 1/2 cup of chopped pecans to the oat mixture for extra crunch. Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
