Like most vegetables, if frozen raw, the texture, taste, colour and nutritional value deteriorates, so make sure you blanch it to preserve these elements. Always use cauliflower that's fresh, too.

If you don’t want to blanch it ahead of freezing, dice or chop the florets finely, freeze on a tray until solid, then transfer to a labelled resealable freezer bag, expelling any excess air. There will be deterioration, as described above, and it's best used in cooked dishes within a couple weeks.

Basic methods for freezing cauliflower

Prep your cauliflower by washing it thoroughly and cutting into equal-sized florets.

How to freeze cauliflower florets

  1. To blanch the cauliflower, bring a pan of water to the boil. Prepare a bowl of iced water and a tray lined with kitchen paper.
  2. Put the cauliflower in boiling water and blanch for about 2 minutes, depending on the size.
  3. Remove the cauliflower with a slotted spoon and plunge into the bowl of iced water. Leave for the same time that the cauliflower was blanched, then drain and arrange on your lined tray.
  4. Once drained and patted dry, lay the cauliflower on a tray and freeze until solid. You can then transfer into a labelled resealable freezer bag, ensuring you remove any excess air before sealing. Blanched cauliflower is best used within 6 months.

Roasting cauliflower

You can roast the cauliflower from frozen. Place on a baking tray, drizzle with a little oil, season and roast at 210C/200C fan/gas 7 for about 20 minutes, depending on size, until tender and cooked all the way through.

Pan-fried cauliflower

Put a small amount of frozen cauliflower into a pan with butter on a low heat, stirring often until tender through.

Microwaved cauliflower

Put the frozen cauliflower into a microwave-safe dish with a splash fo water (about 50ml). Cover with a microwave-safe cover, then blast for about 3 minutes on high, until the cauliflower is tender and cooked through.

How to reheat cauliflower rice

You can defrost in the fridge before using, but frozen cauliflower rice can be microwaved straight from the freezer for about 4 minutes on the highest power in a bowl covered with cling film, mixing half way through.
