It’s no secret that Cameron and I love Mexican food. And it’s no secret that I love to sneak extra veggies onto our plates whenever possible.
Enter Mexican Cauliflower Rice.
To be honest, I received major side eye when I told Cameron I was making a cauliflower rice version of his beloved side dish. He was not amused.
That is, until I presented him with a bowl of this low carb flavor bomb, first smothered with my slow cooker cilantro lime chicken, and later served with a runny egg and avocado as a light lunch.
He was an instant convert, and you will be too.
Why Cauliflower Rice?
If you subscribe to a keto or low carb diet or are eliminating grains for health reasons or dietary considerations, cauliflower rice is a terrific substitute for traditional rice.
This low carb and keto friendly side dish will become a staple in your kitchen. It’s packed with all of the flavor of traditional Mexican rice, but with extra nutrients (and less guilt if that’s your thing).
- Flavor. Cauliflower is a sponge and easily soaks up the seasonings in any given recipe. It won’t taste like a tiny pile of vegetables once you’ve stirred in cumin, garlic, tomato paste, and fresh cilantro. It’s so good that I didn’t stop with mexican rice – try this recipe for cilantro lime cauliflower rice next!
- Texture. Properly cooked, cauliflower rice is light and fluffy with a bit of a bite – just like traditional rice! Be sure to follow the instructions closely, and cook the cauliflower rice (fresh or frozen) until all of the liquid is released and has evaporated.
- Nutrition. Cauliflower rice really is healthier, whether you eat grains or not, and it’s great way to sneak in a few extra veggies without trying too hard. With fewer calories, fewer carbs, more fiber, plenty of antioxidants, and all the Vitamin C you need in a day, swapping Mexican cauliflower rice for traditional rice from time to time will do your body good!
Key Ingredients
- Riced Cauliflower: we love using fresh cauliflower rice, but you can definitely use frozen too!
- White Onion and Garlic: onions and garlic are the base flavors in Mexican rice.
- Jalapeno: minced, with or without seeds. Without seeds, the jalapeno will add flavor without heat.
- Tomato paste: adds depth and flavor, and gives the cooked cauliflower rice beautiful color!
- Cumin and Paprika: to season the rice and add smoky notes.
- Fresh Cilantro: finely chopped, and folded in just before serving.
- Lime Juice: we prefer fresh lime juice whenever possible – you can’t beat the flavor!
How to Make Mexican Cauliflower Rice
Properly prepared, cauliflower rice is chewy, nutty, and deliciously addictive. For best flavor and texture, make the rice from scratch using a fresh head of cauliflower. Cauliflower happily absorbs seasonings, so be generous – jalapeno, garlic, tomato paste, lime juice, and cilantro are each prominent but balanced in our Mexican cauliflower rice. This dish is both easy and flexible, make in one skillet, and ready in under 30 minutes.
Before you start! This recipe moves pretty quickly, so get your mis en place (aka “prep”) in order before you start – chop the onions and cilantro, mince the garlic and jalapeños, prep the spices, and have your fresh limes ready.
- Rice the cauliflower. Divide a head of cauliflower into bite sized florets (smaller pieces will process more evenly) then transfer to a food processor fitted with a standard s-blade; for best results, don’t fill the bowl more than halfway full or the cauliflower won’t evenly process. You may need to process the florets in batches, depending on the size of the cauliflower. Press the “pulse” feature 20-30 times, or until the florets have been processed into a fine, rice-like texture. It’s okay if there are some slightly larger pieces. Just be sure to pulse, not blend, so that you don’t end up with mush. Click the link for everything you need to know about ricing your own cauliflower.
- Heat olive oil in a large, 12″ skillet then add the onions; saute, stirring occassionally, until the onions are soft and starting to brown around the edges.
- Add the garlic and jalapeno and saute until fragrant.
- Add the tomato paste, cumin, paprika, and salt. Work the tomato paste and spices into the vegetables until evenly distributed.
- Add the riced cauliflower to the skillet. Stir, stir, stir until the rice is worked into the skillet ingredients. Continue sautéing, stirring occasionally, until the cauliflower releases its moisture and is cooked through, but not completely soft. Be sure to stir frequently so the cauliflower cooks evenly.
- Once cooked through, remove from heat and stir in the lime juice and cilantro. Taste for seasoning, and adjust as needed with salt, lime juice, or cilantro.
A note about texture – depending on the size of the cauliflower rice and how much moistures it contains, the cooking time will vary. The best way to know the rice is cooked is to taste it. Fully cooked cauliflower rice will be chewy, but still a bit firm with a light bite. Overcooked cauliflower rice can be soggy, so pay attention to the pan and start tasting for texture around the 5-minute mark.
Chef’s Tips!
- Use a large 12″ skillet. This allows the cauliflower rice to both sauté and steam at the same time for best flavor and texture.
- Always taste for doneness. Depending on the size of your “rice”, cooking times can vary. First, look for visual cues – fresh cauliflower will look visibly more transparent when finished cooking, and frozen rice will be visibly defrosted. There should be little to moisture in the pan. Taste around the 5-minute mark if using fresh rice, or the 4-minute mark if using frozen rice. Remember, you can always cook a bit longer!
- Use fresh cut cauliflower rice sooner than later to avoid any unpleasant odors.
Can I Use Frozen Cauliflower Rice?
Yes! Replace fresh rice with cauliflower rice in the same order. Cauliflower rice will cook just a bit more quickly – start tasting for texture around the 4-minute mark, and be careful not to overcook. Frozen cauliflower rice will not have the same “al dente” bite of fresh rice, but it definitely wins in terms of time and convenience!
Can I use Store-Bought Cauliflower Rice?
Yes! But check your produce. Most grocery stores carry bagged, pre-rice cauliflower in the produce section, and it sure is convenient. Look for bright white cauliflower rice, without a hint of a green tint (the latter is a signal that the cauliflower was under-ripe, or parts of the stem and/or leaves were riced). The packaging can cause the rice to sweat and release moisture, so be sure to wring it out before using.
Is Mexican Cauliflower Rice Spicy?
Not overly so! There is some spice from the jalapeno, but it’s more flavor and less heat. To make it spicier, keep some of the seeds from the jalapeno, and/or add up to a teaspoon of chili powder.
Is Cauliflower Rice Healthy?
Healthy is subjective, so – that’s up to you! I can tell you that this recipe is Whole30, paleo, and keto friendly, and naturally vegan and grain free. In our house, it’s a great way to sneak extra vegetables onto our plates without feel deprived.

- Food Processor
Ingredients
Instructions
- Rice the cauliflower. Slice the florets from the head of the cauliflower. Fit a food processor with a standard s-blade. Place half the florets into the bowl of the food processor and pulse until riced, scraping down the sides once halfway through to catch any larger pieces. Scrape out the riced cauliflower and repeat with the remaining florets.
- Heat a large 12" skillet over medium high heat. Add the oil and heat until it shimmers. Add the onion and sautee until soft and translucent, stirring occasionally, 5-6 minutes.
- Add the garlic and jalapeno and sautee, stirring frequently, until fragrant, 1-2 minutes.
- Add the tomato paste, salt, cumin, and paprika. Work the tomato paste into the rice, stirring until it's fully incorporated. Cook at least 2 minutes to cook off the canned flavor.
- Add the cauliflower rice and stir continuously until all ingredients are very well combined. Continue sautéing, stirring occasionally, until the cauliflower releases its liquid and is dry and fluffy, 5-8 minutes. See Note 2.
- Remove the skillet from heat and stir in the cilantro and lime juice. Serve right away.
Notes
- Store in a tightly sealed container in the fridge for up to 3 days.
- Reheat in the microwave in 30-second intervals or in a skillet over a medium high flame for 2-3 minutes.
- If making for meal prep, reserve fresh cilantro and add just after reheating.

I am buying my cauliflower already riced. About how much should I use for this recipe? Thanks!
Danielle
It’s about four cups, or a pound. This is a great question, I’ll update the recipe card to add this note. Thanks!
Gladys
You failed to update.the.recipe card!! This info is important for newbies.
Joseph
Please update the recipe card.
Diane K (foodieforpeace)
Just finished this dish, which was a side to a local Mexican take out. Easy to prep and prepare. Still has texture but not raw at all. Way tasty. Too good NOT to put in rotation.
Gaby
Hi what are the nutritional facts if just eating the rice? Thanks!!!!
Danielle
Hi Gaby – the nutrition card below the recipe is just for the rice. The facts for the bowl are in the notes section of the recipe card.
Gaby
Thank you!!!! It was delicious!!!!
Kim Tankersley
How many servings? 13 carbs per serving or entire recipe?
Nancy
Excellent recipe! Tastes like Mexican rice but its all vegetables! Suggestion: it would be helpful to give a weight for the cauliflower, or indicate number of cups of the riced cauliflower. I ended up adding 2 more tablespoons of tomato paste to mine as it looked pink instead of reddish. I think my cauliflower was bigger than the recipe intended.
Jamie
Absolutely excellent! Wouodbt change a thing. Great recipe
joanne fleming
I have now made this three times and I’m OBSESSED. It’s the best whole30 recipe using cauliflower rice that I’ve ever found.
Tricia Vix
Great recipe! Suggestion. Many of us don’t measure with grams. Having the cup converter would be appreciated. I find myself digging on the intranet for a converter and eventually find it but it’s a pain. I’ll still make this again. Loved the extra cilantro and lime squeeze at the end!
Nancy
My mouth is watering and I want to taste this … I can’t wait to try this seems so yummy😊
Susannah
I added a little bit of the TJ Elote seasoning, chili powder and coriander but other than that, this was quick and delicious.
Mel
Best Mexican caulirice recipe I’ve tried so far! Very flavorful, quick and easy!!
Brandy
Made this last night to go with my hubby’s charro beans and some cornbread. We looooove Mexican rice, so I was worried about introducing this version but it actually turned out pretty well. I did heed the warning and prepped everything before I started cooking and I feel like it helped a lot. I followed the recipe almost exact except I used frozen cauliflower rice, I added a little chili powder and more garlic than was called for. I used 2 small bags of Jolly Green Giant cauliflower rice which came to about 4 cups total. I thawed and wrung out as much moisture as I could. The hubs said it was ok for being all veggies, but he’s willing to eat leftovers. I feel like this is a good base for this kind of receipt, but something was missing. I will use this over and over again and tweak here and there. Thank you for sharing!
Teresa McCreary
Delicious!! Great flavor.
Alana
This looks amazing!! I’ve been trying a few different kinds of cauliflower rice and I can’t wait to try this one. Thanks!
AL
This was delicious. My guests didn’t even know it wasn’t real rice. I used bagged cauliflower rice, which I dried out in a 175° oven for 30 min before adding to the skillet. This recipe will be on a regular rotation.
Pj
I made this recipe using two bags frozen riced cauliflower drained and rung out in a tea towel. Also added 1/4 to 1/3 cup chopped green bell pepper and 3/4 teaspoon salt instead of 1 teaspoon. Delicious! My husband said “keep this recipe”, we LOVED this! Recommending this recipe to friends.
Jen
OMG, this was an amazing substitute for mexican rice! I love my starches but the family is trying to eat healthier. I tried cauliflower rice before and it was bland. I made this one and the hubby loved it! Even my stepson ate it and he doesnt like anything! LOL We had it with garlic lime flank steak.
Hubby wants me to make turkey taco bowls next time with black beans. This is definately a do-over in out household! 😋
KN
Added some cayenne and black beans – SO good. Maybe the best version of cauliflower rice I’ve ever had!
Annie
My children love to eat MEXICAN CAULIFLOWER RICE and I will try it for my children and my husband as well. If you have a recipe for Haitian Food then please do share it with me.
Jade
it’s okay
Mia
I used one cup of frozen cauliflower rice for two of us. I just threw it in and stirred it around following the recipe. I also used salsa instead of tomato paste and jalapeño. I also threw in a handful or so of frozen corn and a little Tabasco. It was great. Thanks!
Kristen
PHENOMENAL
Meghan
This recipe was so quick and easy. Took it up a notch with some Serrano and banana peppers. used the lemon and garlic riced cauliflower from the freezer, defrosted and pat dried. Served with adobo chicken.
Angela
Absolutely love this! Left out the jalapeño and served with mixed chilli beans. Definitely a keeper!
Lin
We love this and have made it several times. I add some of the jalapeño seeds because we love spicy food. I used two bags of frozen cauliflower rice and cooked them in the microwave before following the other steps. Quick and easy way to make this. Thanks for your hard work in creating these recipes.
