If you’re like me, you hate to waste food! While fresh cauliflower lasts up to a few weeks in the refrigerator, it’s nice to have the option to freeze it if you want to preserve it even longer.

Frozen cauliflower makes an excellent nutrient-dense addition to smoothies, or you can toss it into soups or stews to add more bulk, fiber, and nutrition.

Cauliflower is budget-friendly and easy to find at the grocery store. Let me show you how easy it is to freeze cauliflower!

Why You Need This Recipe

  • 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. That’s why you need this guide on the best way to freeze cauliflower.
  • 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.
  • Reduce your food waste by freezing extra cauliflower so it doesn’t go bad. Frozen cauliflower will last up to several months in the freezer.

Key Ingredients

Let me show you exactly how to freeze cauliflower.

  • You’ll need a head of cauliflower to make frozen cauliflower. You can also freeze cauliflower florets. You can prepare and freeze up to several heads of cauliflower at one time.
  • You will also need water and ice to make an ice bath to stop the cauliflower from cooking once you steam or blanch it.

Recipe Steps

Step One

The first step when you want to freeze cauliflower is to break it up into florets. You can also use a food processor to gently break up the whole cauliflower head into small 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 such as vitamin C.

Blanching cauliflower is as simply as placing the florets into a pan of simmering water for about 1-2 minutes. You can also make Instant Pot Steamed Cauliflower to prep it for freezing.

Step Three

After you have lightly steamed or blanched the cauliflower florets, give them a rinse under cool running water. Or, place them in an ice bath for a few minutes to stop the cooking process.

Then, 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 or freezer bags for long-term freezing.

How to Use Frozen Cauliflower

Blanched frozen cauliflower florets are actually very versatile. You can throw them into all kinds of dishes including smoothies or savory stews.

You don’t even have to defrost your frozen cauliflower before you use it. For recipes like a vegetable stew, just add a few minutes extra cooking time to your recipe to ensure that the frozen cauliflower gets warmed through.

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.
