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.
Instant convert! And you will be too.
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 loads more nutrients (and less guilt if that’s your thing).
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.
- Divide a head of cauliflower into bite sized florets; smaller pieces will process more evenly.
- Place the cauliflower florets into 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’ll need to do this in 2, maybe 3, 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.
- This recipe moves pretty quickly, so get your mis en place (aka “prep”) in order before you start.
- You’ll need a chopped white onion, minced garlic, minced jalapeno, tomato paste, cumin, paprika, salt, some fresh lime juice, and lots of chopped cilantro.
- Heat oil in a 12″ non-stick skillet over medium high heat. Add the onion and sautee until soft and starting to brown around the edges. Then add the minced garlic and jalapeno and sautee until very 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.
Can I use frozen cauliflower rice?
Yes, but with notes and caution. Frozen cauliflower rice should first be defrosted and then thoroughly dried – simply place into a cotton kitchen towel and wring it out. Frozen cauliflower rice will cook more quickly, so be sure to pay attention to the pan.
Can I use store-bought cauliflower rice?
Again yes, but with notes. 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.
What to serve with mexican cauliflower rice
You can use this Mexican cauliflower rice anywhere you’d use regular cauliflower rice:
- As a side dish for low carb tacos or fajitas
- Topped with cilantro lime chicken or seasoned black beans
- Stuffed into burritos
But my favorite way is for breakfast – yes, breakfast! I whipped up a keto bowl and it was OMG delicious. Layer the mexican cauliflower rice into a bowl with a bit of shredded cabbage for crunch; top with half an avocado, a poached egg, and a little queso fresco if you’re feeling frisky. Easy, nutritious, and filling.
Tips for making this recipes perfectly
- Process the cauliflower florets in batches for even ricing. Don’t fill the bowl more than halfway full, and be sure to use the pulse feature, rather than blending it on the continuous mode.
- Use a 12″ skillet. A larger skillet provides plenty of room to cook the cauliflower rice properly (a combination of sautéing and steaming for best flavor).
- Pay attention the pan and do not overcook the rice. Cooking time may vary, so it’s important to taste for texture starting around the 5-minute mark.

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!
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!!!!
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.

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.

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!
