Low Carb Mexican Cauliflower Rice Recipe

Cauliflower rice is definitely one of my favorite foods. It really has it all. It is healthy, flavorful and also really easy to make. Since cauliflower rice is so popular right now, you don’t even have to make it—you can just buy it in the freezer section of the grocery store! It doesn’t get any more simple than that.

Plus, cauliflower is super healthy. It’s packed with antioxidants, beneficial fiber, tons of choline and other nutrients that make it such a powerhouse food. (We love it in our Cauliflower Au Gratin and Cheesy Cauliflower Casserole too!)

So, once you are armed with your frozen cauliflower rice and your desire for a delicious, Tex-Mex inspired meal, you are ready to make this Mexican cauliflower rice!

ingredients to make mexican cauliflower rice


See recipe card below this post for ingredient quantities and full instructions.

  • Olive oil
  • Ground beef – I like to use 85/15 ground beef, which means the meat is 15% fat. I find that this is the perfect amount of juicy meat and marbled fat. You can use a leaner meat if you’d like, but just keep in mind that fat is flavor! 
  • Chopped onion
  • Red bell pepper – Red bell peppers are sweeter than any other color bell pepper which is why it is my favorite one to use. They also add a great pop of color to the dish that makes it even more appealing. 
  • Taco seasoning –  You can use store-bought or homemade taco seasoning.
  • Fire roasted tomatoes – Fire roasted tomatoes have a beautiful, flavorful char on the outside that makes the sauce for this cauliflower rice dish really tasty. 
  • Cauliflower rice – You can make your own cauliflower rice by pulsing cauliflower florets in a food processor until it’s small and crumbly. Or, you can just buy frozen cauliflower rice, which can be found in almost every grocery store. 
  • Chicken broth
  • Shredded Mexican cheese – Shredded Mexican cheese is a blend of cheddar cheese and Monterey Jack cheese.
  • Cilantro 

Mexican Cauliflower Rice Recipe Variations

I adore this cauliflower rice recipe exactly as it is written, but there are a few tweaks and substitutions you may want to try:

  • Make this dish vegetarian simply by omitting the ground beef and use veggie broth in place of chicken broth. You can add some chopped zucchini, sliced mushrooms, or even some sliced jalapeños to the dish if you want more veggies. Add the veggies along with the bell pepper, then continue to follow the recipe as written. 
  • Replace the fire roasted tomatoes with 2 cups of fresh chopped tomatoes. I like to do this when I have lots of fresh tomatoes in my garden in the summer. 

How to Make Mexican Cauliflower Rice

  1. Cook the beef: Heat the olive oil in a large, oven safe skillet and add the ground beef. Cook the beef until it is no longer pink and starting to brown. Be sure to break up the beef with your spatula as it cooks. 
  2. Cook the veggies: Add the onion, bell pepper, and taco seasoning to the same skillet with the ground beef. Sauté the veggies until they are nice and tender. Stir in the cauliflower rice.
  3. Add the broth: Stir the chicken broth into the skillet and let the mixture simmer for about 6 minutes. Almost all the liquid will evaporate and help the rice not be too mushy.
  4. Add the cheese: Take the skillet off of the burner and sprinkle the whole dish with shredded cheddar cheese. Place the pan under a broiler to melt and brown the cheese. 
  5. Eat: Once the cheese is bubbling and browned, sprinkle the cauliflower rice with some chopped cilantro and enjoy while it is nice and hot.

Quick Tip

To make fresh cauliflower rice, pulse cauliflower florets in a food processor until it looks like small crumbles. Fresh cauliflower rice is a little less watery than frozen cauliflower rice; it will take about a minute or two longer to finish cooking.

How to Store Mexican Cauliflower Rice

If you happen to have leftovers, you can store them in an airtight container in the fridge. The Mexican cauliflower rice will keep for about 2-3 days. 

To reheat the cheesy cauliflower rice, pop it into the microwave for about a minute. Once the rice is steaming hot, it is ready to eat! 

Serving Suggestions

This cauliflower rice is filling enough that it can be served on its own as a one-dish dinner. Try serving some tasty taco dip as an appetizer before your Mexican cauliflower rice meal, or make a tray of sheet pan nachos. A delicious coconut tres leches cake is the perfect way to finish your Mexican-themed meal.


How do you make cauliflower rice not soggy?

To make sure your cauliflower rice is not soggy, be sure to cook the rice until all the liquid evaporates. Once there is no liquid in the pan, the cauliflower will crisp a little bit and not be too soggy.

Is cauliflower rice the healthiest rice?

Cauliflower rice is extremely healthy. It is full of B vitamins and minerals, far more than you would find in regular rice.

Does cauliflower rice spike blood sugar?

Cauliflower is very low in carbs, so it will have less of an effect on blood sugar levels than regular rice. It is a great option for those with diabetes or anyone following a keto diet.
