Being born and raised in Texas, Mexican or Tex-Mex food is life, and on the menu at least a few times a week.  As a kid, I always ordered cheese enchiladas but always left the Mexican rice on my plate but as an adult it was one of my favorite parts of the meal!  I think it was because I finally discovered how delicious it was mixed with the sauce, cheese, guacamole…now my mouth is watering, but you get the point!

So, I really wanted a side with Mexican flare that could fill in for my rice, so naturally cauliflower rice was the answer.   I mean isn’t it the answer for everything in the low carb and keto world!?

Quick and Easy Keto Mexican Rice

This dish could not be more simple and comes together in just minutes so it won’t add any additional prep time to dinner.  We use it for a base to taco or fajita bowl or serve it as a side with my cheesy enchilada casserole!

Ingredients for the Keto Mexican Cauliflower Rice

The ingredient list for this keto cauliflower rice recipe is short and sweet!  Diced onion, bell pepper and garlic create the flavor base for this easy dish.  Then everything gets spiced up with a little Fiesta Brand Chili Powder, Garlic Powder and Cumin.  The spices get added to the sauted veggies prior to the caulilofwer rice to help really bring out the amazing flavors of the spices.  Then, in goes the cauliflower rice.  Everything gets sautéed quickly together and DONE!

Fresh or Frozen Cauliflower Rice?

I’m going to be really honest here.   I like using frozen cauliflower rice because its quick and convenient…and maybe a little lazy.  No not really, but I find making fresh cauliflower rice messy and frankly a pain.  Yes, it’s easy to do, BUT most days, by the time I get to my dinner, I’ve already cooked a full homemade breakfast, dinner and dessert for guests we have on the ranch.  The last thing I want to do is pull out my food processor or grater and make fresh cauliflower rice.  Bottom line…you can use fresh or frozen, both will work great and require about the same amount of cook time.

  • Hi Emilie,
    This looks and sounds so delicious. I will try it out this week, as I was planning to make Tex-Mex of some kind. I would LOVE to be a reviewer of your new cookbook! I got your email today, and tried 3 times to send you my name and email address when you asked for people who would like to review your new cookbook. Unfortunately, I kept getting the message that my email was not able to be delivered. Same thing when I sent you an email on the same email address I usually use to contact you. So, please add me to your review list of people requesting to do this. I just started a small business cooking low carb lunches for people, so I am always perusing the internet for new low carb recipes. This would be a great fit if I am chosen. Thanks so much! Tina
