In these crazy times, it’s even more important than ever not to waste food. I found myself with an extra head of cauliflower recently, but I couldn’t use it in time before it was going to go bad. So, I decided to freeze it.

You might think that freezing vegetables is as easy as popping them into a zip-top bag and putting it into the freezer. But, there are actually some better and safer ways to freeze vegetables, including cauliflower, that reduces the chance of food-borne illness and improves the quality of the frozen vegetables.

The bottom line is that you really must blanch (cook in hot water) or steam most vegetables before you freeze them. This helps get rid of any microbes and also helps preserve the quality of the veggies once you use them later. Don’t worry, it’s not that hard to do, and I will show you exactly how I do it.

Recipe Steps

Step One

The first step when you want to freeze cauliflower is to break it up into florets. You can use a sharp knife to cut the cauliflower in half, then use your hands to break up the florets into single pieces.

Step Two

Next, place your florets in a steamer basket or a microwave safe bowl. You can also blanch your cauliflower instead of steaming it, but I prefer steaming since it is less likely than blanching to leach out all the nutrients.

Step Three

After you have lightly steamed or blanched the cauliflower florets, you can use tongs to transfer them a parchment-paper lined baking sheet. This allows the individual cauliflower florets to freeze without slicking together. If you skip this step, you might end up with a big mass of frozen cauliflower that will be impossible to break up.

Step Four

Then, place the baking sheet in the freezer for up to 24 hours. You can then transfer the frozen cauliflower florets to a zip-top bag for long-term freezing. I like to use frozen cauliflower florets in my Peanut Butter Cauliflower Smoothie and my Vegan Gingerbread Smoothie recipes.

It’s that easy! An added benefit of steaming the cauliflower before freezing it and then using it in a smoothie is that it will be easier to digest and is less likely to make you feel bloated.
