Berry Crumble Cooking Guide

Follow these simple steps to create your berry crumble:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your crumble bakes evenly and achieves that golden-brown perfection.
Step 2: Prepare the Filling
In a large mixing bowl, combine the frozen mixed berries with the freshly squeezed lemon juice. Add the granulated sugar and cornstarch, stirring gently to coat the berries. This mixture will create a luscious filling as it bakes.
Step 3: Transfer to Baking Dish
Pour the berry mixture into your prepared 9×13 baking dish, spreading it out evenly. This ensures that every bite is packed with flavor.
Step 4: Make the Crumble Topping
In a separate bowl, mix together the all-purpose flour, dark brown sugar, ground cinnamon, and salt. Add the cold cubed butter and use a pastry cutter or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs.
Step 5: Assemble the Crumble
Sprinkle the crumble topping evenly over the berry mixture in the baking dish. Don’t worry if it’s not perfect; the unevenness adds to the rustic charm of your berry crumble!
Step 6: Bake
Place the baking dish in the preheated oven and bake for 35-40 minutes, or until the topping is golden brown and the berries are bubbling. Your kitchen will smell heavenly during this time!
Step 7: Cool and Serve
Once baked, remove the berry crumble from the oven and let it cool for about 10-15 minutes. This will allow the filling to set slightly. Serve warm, topped with a scoop of vanilla ice cream if desired.
Customize for Your Needs

Berry crumble is incredibly versatile! Here are some ideas for customizing this recipe:
- Add chopped nuts, such as almonds or pecans, to the crumble topping for added crunch.
- Incorporate oats into the topping for a heartier texture.
- Use different fruit combinations, like apples or peaches, for a unique twist.
- Sprinkle in some coconut flakes for a tropical flavor.
Feel free to experiment and make this berry crumble your own!
Steer Clear of These
While berry crumble is quite forgiving, there are a few things to avoid:
- Don’t use fresh berries in this recipe, as they may not yield the same juicy results as frozen ones.
- Avoid overmixing the crumble topping; you want it to be crumbly, not a smooth dough.
- Don’t skip the cornstarch! It’s essential for thickening the berry filling.
By steering clear of these pitfalls, you’ll ensure a successful berry crumble every time.
Leftovers & Meal Prep
Berry crumble is perfect for leftovers! Here’s how to handle them:
You can store any leftover berry crumble in the refrigerator for up to 3 days. Simply cover it with plastic wrap or foil to keep it fresh. To reheat, pop it in the oven at 350°F (175°C) for about 10-15 minutes until warmed through. You can also enjoy it cold, straight from the fridge!
If you want to meal prep, consider making a double batch. You can freeze the unbaked crumble for up to 3 months. Just assemble the berry filling and crumble topping in a baking dish, cover tightly with foil, and freeze. When you’re ready to bake, you can add an extra 10-15 minutes to the baking time.
Ask & Learn
Can I use fresh berries instead of frozen?
While frozen berries work best for this recipe, you can use fresh berries if they are in season. Just be mindful that you may need to adjust the sugar depending on the sweetness of the fresh fruit.
What can I substitute for the butter in the crumble topping?
If you need a dairy-free option, you can substitute the butter with coconut oil or a dairy-free margarine. Make sure it’s cold, just like the butter!
How do I know when the crumble is done baking?
Your berry crumble is ready when the topping is golden brown and the filling is bubbly. You can also insert a toothpick into the topping; it should come out clean or with just a few moist crumbs.
Can I make this gluten-free?
Absolutely! Substitute the all-purpose flour with a gluten-free flour blend. Just ensure that the blend you choose has a good binding agent, such as xanthan gum, for the best results.
