How to Freeze Cauliflower

PDF print version

If you like frozen cauliflower in the winter, just imagine how good it would taste if you had picked a head yourself and then quickly froze it at home!  It is also one of the simplest ways to put up a vegetable for the winter. Here's how to do it, complete instructions in easy steps and completely illustrated. The cauliflower will taste MUCH better than anything you've ever had from a store.

Directions for Freezing Cauliflower


  • fresh cauliflower - any quantity.  I figure one handful per serving.


  • 1 Large pot of boiling water
  • 2 large bowls, one filled with cold water and ice.
  • 1 sharp knife
  • Vacuum food sealer or "ziploc" type freezer bags (the freezer bag version is heavier and protects better against freezer burn).


Step 1 - Get the cauliflower!

You can grow your own, pick your own, or buy them at the farm market or grocery store. Start with fresh cauliflower - as fresh as you can get. 

Step 2 - Wash the cauliflower!

I'm sure you can figure out how to rinse the cauliflower in plain cold water.   Trim off leaves and cut head into pieces about 1 inch across.

Select firm, young, heads. Split lengthwise so flowerets are no more than 1 1/2 inches across. Remove leaves.


Step 4 - Soak the florets in brine (salt water)

Step 5- Get the pots  ready

Get the pot of boiling water ready (about 2/3 filled) and a LARGE bowl with ice and cold water.




blanching cauliflower Step 6 - Blanch the cauliflower.  

All fruits and vegetables contain enzymes and bacteria that, over time, break down the destroy nutrients and change the color, flavor, and texture of food during frozen storage. cauliflower requires a brief heat treatment, called blanching, in boiling water or steam, to destroy the enzymes before freezing. Blanching times for cauliflower is 3 minutes  (or blanch with steam for 5 minutes) - the duration is just long enough to stop the action of the enzymes and kill the bacteria.

Begin counting the blanching time as soon as you place the cauliflower in the boiling water. Cover the kettle and boil at a high temperature for the required length of time. You may use the same blanching water several times (up to 5). Be sure to add more hot water from the tap from time to time to keep the water level at the required height.

Step 7 - Cool the cauliflower

After vegetables are blanched, cool them quickly to prevent overcooking. Plunge the cauliflower into a large quantity of ice-cold water (I keep adding more ice to it). A good rule of thumb: Cool for the same amount of time as the blanch step. For instance, if you blanch sweet cauliflower for 3 minutes, then cool in ice water for at least 3 minutes. 

Drain thoroughly. 






Step 8 - Bag the cauliflower

I love the FoodSavers (see this page for more information) with their vacuum sealing!  I am not paid by them, but these things really work.  If you don't have one, ziploc bags work, too, but it is hard to get as much air out of the bags.  Remove the air to prevent drying and freezer burn.  If you don't have a foodsaver, see two more methods for removing air, below.

Method 2

Or hold the open bag underwater (keeping the open edge ABOVE water).  The water presure will push most of the air out).  Seal it while it is still in the water. This method gets out most of the air, but the foodsaver gets out twice as much air.

Method 3 - The least effective method is the straw:

 If you don't own a vacuum food sealer to freeze foods, place food in a Ziploc bags, zip the top shut but leave enough space to insert the tip of a soda straw. When straw is in place, remove air by sucking the air out.  To remove straw, press straw closed where inserted and finish pressing the bag closed as you remove straw.

Step 9 - Done!sealed cauliflower

Pop them into the freezer, on the quick freeze shelf, if you have one!


I love the FoodSavers (see this page for more information) with their vacuum sealing! 

Here's an example of one model:

FoodSaver V2840 Advanced Design

This one is the least expensive of the Food Saver models that has all the advamced features, like automatic bag detection and sealing, which makes it faster and easier to seal.  And yes, you can seal and freeze foods with liquids (just freeze the unsealed bag in the freezer overnight, THEN seal it!)

Frequently Asked Questions

  1. I've frozen cauliflower but it seem so limp and fell apart. Any idea why?

    Generally, that means the cauliflower was overcooked.  It only takes 90 seconds in steam or boiling water to heat/cook the cauliflower after removing it from the freezer
  2. How long can they be frozen?

    It depends upon how cold is your freezer and how you packed them.  Colder (deep freezes) are better than frost free compartments, which actually cycle above freezing (that's how they melt the ice).  Vacuum packing results in longer storage capability, too.  Thicker bags also help prevent freezer burn.

    In general, up to 9 months in a ziploc bag in an ordinary freezer, and 14 months in a deep freeze in a vacuum packed bag.  After that, they cauliflower won't make you sick; they just won't taste a s good.

Your directions were so clear & I loved the "hold the bag underwater to remove air" tip! Tomorrow I will freeze some spinach. I made a $10 donation in thanks to you. Sincerely, Pam in Maryland, USA"
