How to Make Dehydrated Cauliflower Rice

If you are backpacking keto, paleo or low-carb, dehydrated cauliflower rice is a real godsend for you. It’s tasty, weights almost nothing and could be used as a base for curries, soups, stews or any other dish you would eat with rice, bulgur or couscous.

Dehydrated cauliflower rice is very easy to make at home.

What you’ll need:

1 medium head cauliflower
1 teaspoon turmeric powder
1/4 teaspoon salt, or to taste


  1. Remove the outer leaves and stalk from the cauliflower head. Cut into florets.

2. Place the cauliflower florets in a food processor. Pulse until you get the texture of rice or couscous.

3. Cook in your favorite way: by frying, microwaving or roasting. I prefer roasting. It gives to cauliflower rice light, fluffy texture and pleasant nutty flavor.

Preheat oven to 400F/200C.  Line a baking sheet with parchment paper. Pour the riced cauliflower onto prepared baking sheet.
Sprinkle with turmeric and season to taste. Mix well and then spread out evenly. Roast for about 15 minutes, mixing once or twice during cooking. Remove from the oven and let cool slightly.

4. Spread the cauliflower rice on dehydrator trays covered with non-stick sheets or parchment paper.

5. Cover with mash sheet to prevent scattering of small dried cauliflower rice pieces throughout the dehydrator.

6. Dehydrate at 135F/57C for about 4-8 hours until completely dry and crunchy.

7. Let cool, then pack into airtight container or zip-lock bag. Store in dry, dark and cool place.


Dehydrated cauliflower rice rehydrates very quickly. Just mix it with equal quantity of hot water, stir well, and let sit in a cozy for 5 to 10 minutes. If you’ll mix it with other ingredients such as meat or vegetables, rehydration may take a bit longer.

    How long is the storage life of product? Will the product last for 5 years or more, if properly stored in proper storage bag as the MRE?

    • Tanya Krezevska on November 21, 2021 at 3:17 pm

      The shelf life depends on many factors. But id dried and stored properly, you can keep it up to 2 years. Never tried to store it for longer period.

    I read where the reason store bought cauliflower rice is more similar to real rice is that they use the stems more than the florets. Just saying.

    What is the best way to store dehydrated cauli rice? About how much room does one head take up in storage once dehydrated?

    • Tanya Krezevska on June 26, 2020 at 9:13 am

      If you wish to prolong shelflife of your dehydrated cauli rice, put it into vacuum-sealed bag and place into freezer.

    I’m excited that I came across this. I just bought a head of cauliflower not realizing hubby just bought some the other day. Seeing as we don’t tend to eat a lot of it I was worried about them going bad in the fridge. I seasoned mine with curry powder and salt. I have never made riced cauliflower before so I am excited to see how it turns out and hopefully have a nice alternative to rice and have some tasty easy meals for when we go camping/ backpacking.

    Theoretically, if we use dehydrated cauliflower rice, we should be able to approach the texture of regular rice, if we use a ratio of about 2 cups of water to one cup of dehydrated cauliflower rice: Bring to boil; lower to simmer for 15-18 minutes, and allow it to rest for 5 or 10 minutes. It should be as close to regular rice as is possible.

    O M G. Just what I was looking for. I recently got a truckload of cauliflower, free. Couldnt resist. I dehydrated all of it in pieces, Next time I will know better.

      You could still probably put it in a processor and “rice” it. I would try small batch. It’s worth a try.

    I’m preparing for a two-week road trip and was worried about what I’d be eating because I have a lot of dietary restrictions. This website is so helpful! I look forward to trying all these dehydrator recipes. Thank you so much!
