Jamie Oliver Frozen Berry Crumble
Jamie Oliver Frozen Berry Crumble is a baked dessert made by topping sweetened frozen berries with a buttery crumble mixture, then baking until the fruit bubbles and the topping turns golden. The frozen berries break down slowly, creating a rich, syrupy base under a crunchy lid.

Ingredients
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
Instructions
Preheat your oven to 180°C (160°C fan). Lightly butter a medium baking dish so the fruit doesn’t stick.
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.
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.
Stir the brown sugar and oats into the crumble mixture. This gives a deeper flavour and a more satisfying crunch once baked.
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.
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.
Remove from the oven and let the crumble rest for 10 minutes. This allows the fruit filling to thicken slightly and makes serving easier.
