It’s so easy to freeze your own cauliflower when you find a great sale. Unless, of course, you’re interested in taking out a second mortgage to afford cauliflower during the winter. You do you.

Can You Freeze Cauliflower?

Absolutely! Freezing cauliflower makes an incredible addition to your freezer essentials for fast and healthy recipes. Paired with some of my 20 Minute Meals, and weeknight cooking just got awesome in your house.

Can You Freeze Fresh Cauliflower Without Blanching?

Yes, if you plan to use it in the next 4-6 weeks. If you prefer to keep it around for longer-term storage, blanching is the way to go.

Blanching helps to lock in the flavor and keeps everything safe for preservation. Thankfully it is an easy process and will take you less than 10 minutes.

How to Use Frozen Cauliflower

The most common use in our house is using it to roast frozen cauliflower. So simple and there is zero prep involved for this fast side (you roast it without even defrosting!). You can also make Cauliflower Tempura, air fryer cauliflower, or these Crispy Cauliflower Fritters.

I often use frozen cauliflower in place of fresh when making Encurtido. And for a fun fridge pickle, check out Quick Pickled Cauliflower.

Pro Tips/Recipe Notes

  • Freeze in portions you plan to use upon defrosting. Quart freezer bags will replace a 15 oz bag from the store.
  • Frozen cauliflower will last in a conventional freezer for six months. If you have a deep freeze/stand-alone freezer, you’re safe to keep them in there for up to a year.

  • Rinse the head of cauliflower in clean water.
  • Break apart the head or cut into florets, removing the stem.
  • Bring a large pot of water to a rolling boil. Set up a bowl of ice water.
  • Add cauliflower to the boiling water and boil for 3 minutes. Don't overcrowd the pot. Cook in batches if needed.
  • Once the time is up, strain the florets through a colander or scoop pieces out of the water with a slotted spoon and immediately add to the ice water for two minutes.
  • Strain again and set aside to drain. Pat dry with a clean towel.
  • Line a rimmed baking sheet with parchment or a silpat. 
  • Add the cauliflower to the baking sheet without crowding the tray and place the tray in the freezer. 
  • Freeze for three hours. 
  • Break apart any clumps that have formed on the baking sheet and transfer to freezer-proof storage.


There is no need to thaw before adding to dishes.
Store unblanched in the freezer for up to two months, or blanched for up to 12 months.
