Step‑by‑Step Instructions for Rustic Berry Crumble
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is essential for achieving that perfectly baked Rustic Berry Crumble. Ensure your cast iron skillet is clean and ready to go; a well-seasoned skillet will help prevent sticking and enhance the flavors.
Step 2: Prepare the Berry Filling
In a medium bowl, combine 2 cups of mixed berries with ¼ cup granulated sugar, 1 tablespoon lemon juice, and 1 tablespoon cornstarch. Gently toss until the berries are well-coated. Allow the mixture to sit for about 10 minutes, letting the sugar draw out the juices, which creates a syrupy filling.
Step 3: Make the Crumble Topping
In another mixing bowl, whisk together ¾ cup all-purpose flour, ½ cup rolled oats, ½ cup brown sugar, 1 teaspoon ground cinnamon, and a pinch of salt. Next, add in ½ cup of cold, diced unsalted butter. Using a pastry cutter or your fingers, mix until the mixture resembles coarse crumbs with some larger chunks.
Step 4: Assemble the Dish
Pour the berry mixture into the prepped cast iron skillet, spreading it evenly across the bottom. Next, take the crumble topping and sprinkle it generously over the berries, making sure to cover them entirely for that delicious, crunchy finish.
Step 5: Bake the Crumble
Place your skillet in the preheated oven and bake for 30–35 minutes, until the topping is golden brown and the berry filling is bubbling around the edges. You’ll know it’s ready when the top is crisp and the smell of warm berries fills your kitchen.
Step 6: Cool and Serve
Once baked, remove the Rustic Berry Crumble from the oven and let it cool for about 10 minutes. This cooling time allows the juices to thicken slightly, making it easier to serve. Prepare to dish it out warm, ideally paired with vanilla ice cream or whipped cream for an added treat!
