What Is Jamie Oliver’s Frozen Berry Crumble?

Jamie Oliver Frozen Berry Crumble Ingredients List

For the Berry Filling

800 g frozen mixed berries
3–4 tablespoons caster sugar (adjust to taste)
1 tablespoon cornflour
Zest and juice of ½ lemon

For the Crumble Topping

150 g plain flour
100 g cold butter, diced
75 g light brown sugar
50 g rolled oats
Pinch of salt

How to Prepare Jamie Oliver Frozen Berry Crumble – Simple Steps

Step 1: Preheat the oven

Preheat your oven to 180°C (160°C fan). Lightly butter a medium baking dish so the fruit doesn’t stick.

Step 2: Prepare the fruit filling

Place the frozen berries straight into the baking dish—no need to thaw. Sprinkle over the caster sugar, cornflour, lemon zest, and lemon juice. Stir gently until the berries are evenly coated. The cornflour is essential here, as frozen fruit releases more liquid during baking.

Step 3: Make the crumble topping

Put the flour and salt into a bowl. Add the cold butter and rub it in with your fingertips until the mixture resembles coarse breadcrumbs. Keep it loose rather than overworked.

Step 4: Add sweetness and texture

Stir the brown sugar and oats into the crumble mixture. This gives a deeper flavour and a more satisfying crunch once baked.

Step 5: Assemble

Evenly scatter the crumble topping over the berry mixture. Don’t press it down—loose topping allows hot air to circulate and crisp it up.

Step 6: Bake

Place the dish in the oven and bake for 40–45 minutes, until the fruit is bubbling around the edges and the topping is golden and crisp.

Step 7: Rest before serving

Remove from the oven and let the crumble rest for 10 minutes. This allows the fruit filling to thicken slightly and makes serving easier.

FAQs

Do I Need to Defrost Frozen Berries Before Making Crumble?

No, frozen berries should be used straight from the freezer. Defrosting them first releases too much liquid, which can make the crumble watery instead of thick and jammy.

Why Is My Frozen Berry Crumble Watery at the Bottom?

Frozen berries release more juice as they bake. Adding cornflour to the fruit and letting the crumble rest for a few minutes after baking helps the filling thicken properly.

How Do I Stop the Crumble Topping from Going Soggy?

Make sure the butter is cold and don’t press the topping down. A loose crumble allows hot air to circulate, keeping the topping crisp and golden.

Can I Make Frozen Berry Crumble Ahead of Time?

Yes, you can assemble it a few hours in advance and keep it in the fridge. Bake just before serving for the best texture, or reheat gently in the oven.
