Learn how to freeze cauliflower rice, without blanching! Plus the fastest way to rice cauliflower and how to use cauliflower rice once it’s frozen. Don’t forget to try my Spanish rice and Instant Pot brown rice recipes.

Cauliflower rice has been popular for quite some time, but it wasn’t until I learned how easy it was to make your own cauliflower rice that I fully embraced it.
I mean, why in the world would I pay $2.50 for a small bag of cauliflower rice – knowing FULL WELL that I’d need 2-3 bags for just one dinner – when I could pay the same price for a full head of cauliflower and make my own?! I mean, I’m saving 66% right off the bat by doing it myself!
Well friends, the deal just got better, because today I’m showing you how to FREEZE cauliflower rice. That way you can stock up when it’s on sale, save a ton of money AND save yourself time later on by having it ready to go in the freezer!
The Best Cauliflower For Freezing Cauliflower Rice
- This should go without saying, but before you can FREEZE cauliflower rice, you need to MAKE cauliflower rice.
- And before you MAKE cauliflower rice, you need to BUY cauliflower. Or grow your own. Your call.

In either case, you don’t need special cauliflower to make and freeze cauliflower rice. You can start with a whole head OR you can start with pre-cut cauliflower florets. Pick whichever is on sale or available in your area.
Tip: Whole heads will be cheaper in most instances, but when they’re priced per pound, weigh each head so you know how much you’re actually going to pay.
They’re surprisingly heavy! Then you can better compare the price of the whole head of cauliflower versus the pre-cut florets.
Making Cauliflower Rice for the Freezer
As I explained in my how to make cauliflower rice post, there are a few ways to go about making cauliflower rice. Before you start though, make sure you wash your cauliflower using the natural produce wash option that works best for you.
Knife and cutting board
No special tools are required! You can go old school and use a knife and cutting board to make cauliflower rice. It’s a bit tedious and time-consuming and messy (heads up), but it CAN be done.
Box grater
You guys, this method is AWESOME. It’s much easier than using a knife and cutting board and pretty much everyone has a grater, right? (If not, I have one just like this one and it gets the job done!)

Food Processor
I didn’t have a food processor when I first wrote this post, but I took the plunge after WAAAY too many Whole30 chopping sessions, and now it’s my favorite way to make cauliflower rice.
(At the recommendation of my sister-in-law, fellow crunchy mama of three, I bought this food processor.)
Use the plate with the large-hole grater and feed the food processor cauliflower florets. Stop when you run out of florets. Done!
Blender
I haven’t personally tried this method myself, but according to this blogger, you can put chopped cauliflower in a blender, fill it to the max fill line with water, and hit pulse until you have crumbles.
Drain the cauliflower in a colander like this one and BOOM – cauliflower rice.
I have this Blendtec blender and honestly, I think this method might accidentally give me a cauliflower sauce (which is TASTY on Pasta Primavera). If you try it though, leave me a comment below and let me know how it goes, mkay?
How to Freeze Cauliflower Rice
Okay, now that you have cauliflower rice, let’s freeze it!
Step 1. Make sure your rice is completely dry.
This probably isn’t an issue if you used a knife, box grater, or food processor. If you used the blender method, make sure your cauliflower rice is super dry. I like to use my DIY salad spinner method to get out all the excess water.
Step 2. Determine the portions of rice.
- This might not seem like a big deal, but it is. You want to make sure that when you thaw the cauliflower rice, later on, you’re thawing enough for dinner and maybe a leftover lunch… but you don’t want to thaw too much… especially if your family isn’t keen on eating leftovers.
- For my family of four, I freezer cauliflower rice 4 cups at a time and odds are there are just enough leftovers for one lunch.
- If you’re not sure how much cauliflower rice to freeze in one package, I recommend allotting ½ cup per person if it’s a side dish, or 1 cup per person if it’s the main element (like Korean Beef Bowls or Slow Cooker Beef Ragu).
Step 3. Portion out the cauliflower rice.
- Guess what friends – you can go straight from cauliflower rice to the freezer WITHOUT cooking it first!
- That’s good news to this mama because I certainly don’t have the energy to COOK several heads of cauliflower rice once I’ve finally finished chopping it all up, LOL!
- Using freezer-safe containers (I use resealable freezer bags), portion your rice for the freezer. Four cups of cauliflower rice just fit into one-quart baggies. Two cups will fit in a sandwich baggie.
- If you’re working solo, I highly recommend these baggie holders so you can get the cauliflower rice into the bags without making a huge mess all over the place. They’re inexpensive and TRULY a lifesaver!

Step 4. Get all the air out of the bag.
You want to avoid freezer burn, so make sure you get as much air out of the bag as possible.
Step 5. Label the bag.
You’ve probably heard me say this a thousand times when I showed you how to freeze tomato paste and how to freeze pizza dough and how to freeze ginger and how to freezer herbs and how to freeze yogurt and how to freeze bread, but make sure you label your storage bags.
In the case of freezing cauliflower rice, you want to write what it is, how much there is, and the date you prepared it.
Do NOT blindly toss a full bag of cauliflower rice in the freezer and think you’ll know what it is later. Because you won’t. Trust me on this one.
Step 6. Freeze the cauliflower rice!
When your bags are full and labeled, toss them in the freezer!
- I like to freeze them flat and stack them on top of each other for the first day. (make sure you have a good seal!)
- That way they can be re-arranged into a “bookshelf” of sorts later on. Storing items like a bookshelf is one of the most efficient ways to use freezer space, plus it makes it easier to find later on!
- I would be a poor teacher if I didn’t tell you that if you’re going to make and freeze cauliflower rice, it’s worth your time to do several heads of cauliflower at one time.
- You’ll make a mess once, clean it up once, and you’ll have tons of cauliflower rice in the freezer for whenever you need it!
How to Cook Frozen Cauliflower Rice
You’ll use your frozen cauliflower rice just like you would fresh cauliflower rice in any recipe. It might take a minute or two longer to cook, but not much because the rice is so small and will cook quickly!

Feel free to play around with the flavor and season as desired! Try adding some:
- salt
- garlic
- pepper
Psst! If you’re going to add salt, I highly recommend Ava Jane’s Kitchen. You may think all salt is created equal, but unfortunately, 90% of the salt produced around the world contains microplastics (gross, right?). Ava Jane’s Kitchen is an exception. Their salt is 100% microplastic-free, and it’s SO GOOD!
Plus, you can get a bag for just 1¢!! (Get your penny bag of salt on this page.)
FAQs
Yes! Cauliflower rice freezes wonderfully and the taste isn’t affected either! Be sure to read all my steps on how to freeze cauliflower rice.
The good news is yes, you can freeze cooked cauliflower rice. The bad news is, your rice will have a different texture than if you were to freeze uncooked rice. I recommend that you freeze your rice when it is uncooked.
In order to defrost cauliflower rice, you need to put your freezer-safe bag of rice into a large bowl of ice cold water. Check it every 10 minutes to see if it is defrosted.

I use the vacuum seal method for all my food heading into the freezer. The oxygen must be removed to prevent freezer burn and/or discoloration of the food. I don’t defrost the cauliflower rice, I use it from the frozen form directly into my recipe and have never had an issue of strange colors. If you are freezing whole cauliflower florets, you must blanche and extract as much water as possible. I freeze first on a tray and then put into a vacuum seal bag and follow that process. I hope this helps.
I tried this a couple years ago and it turned a tan color. Is that normal? I ended up throwing out😟
Hi Zandra!
I understand that cauliflower will turn brown due to oxygen exposure, and also if there is a lack of acidity (meaning your cooking water) during your cooking process. Did you cook the cauliflower rice before freezing? Or did you freeze it uncooked? Tiffany likes to freeze her riced cauliflower uncooked. Perhaps you might try it that way if you haven’t? Hope this helps. 🙂
Thank you so much for this!! I was blessed yesterday with finding a discounted box of cauliflower at the produce market. 10 large heads for a total of $2! I used your method for draining in the salad spinner – brilliant!! I don’t have a fine sieve so this was such a help. I used the vitamix on 1 to pulse with water and then drained. I froze 9 full quart sized bags. THANK YOU!
What a steal, Kathryn! So glad you got to use it all. You are most welcome!
Why would you not blanch it first? When freezing cauliflower heads, you always blanch first, so I’m curious why the rice wouldn’t be blanched?
Linda, most vegetables need blanched before freezing to keep their texture but most riced veggies have a good texture with out blanching.
How long can this be frozen for?
6-12 months if stored correctly!
If I were to freeze it this way….can I then use it for a cauliflower pizza crust?
You probably can Donna! If a recipe calls for frozen cauli-rice, you’re good to go!
I’ll definitely have to try this. Since I eat A LOT of cauliflower rice, I thought it was a good idea to buy a three pound bag of the frozen premade product at Costco. By the time I got it home and in the freezer, it was one huge cauliflower snow ball. I got it portioned out in serving size but only by using my electric carving knife. No fun!!
