Ingredients Needed For Cauliflower Mexican Rice
I always love using fresh produce in my recipes. However, using pre-made ingredients is just so convenient and nice.
I’ve included directions to make this recipe from either canned tomatoes or fresh produce, so you can choose what best suits you!
For this rice recipe, you can use freshly grated cauliflower or the frozen kind. I prefer to grate my own. To do so, you'll need one whole head of cauliflower.
If you use the frozen cauliflower rice, make sure to squeeze all the water out before using it.
You have the option to use pre-canned diced tomatoes with green chilis or to make your own produce mix. In either case, the green chilis, garlic, onion, and lime add amazing flavor.
Once it's cooked, I prefer to add cilantro and red pepper flakes for an extra bit of kick. If you enjoy spicy Mexican food, I recommend giving it a try!
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
- Add a splash of hot sauce to give it an extra spicy kick.
- Use a food processor to chop the florets into rice. This will make clean-up a lot easier too.
- If you prefer not to use the canned tomato blend, you can sub with a fresh mix of about 1 cup diced tomatoes, ½ small onion (or equivalent dried flakes), 2 green chili peppers chopped, 2 cloves minced garlic, and 2 tablespoons lime juice. Then, add additional salt if needed.
How To Make Mexican Cauliflower Rice
Ready to see how you can turn cauliflower into Mexican rice in just a few steps?
All of the details are in the printable recipe card at the bottom of this post. First, here is some additional information that will help you out.
Prep Your Veggies
Start by grating a head of cauliflower with a box grater or food processor. You should get about 6 cups.
If using fresh produce, dice the tomatoes, small onion, and green chili peppers. Add some lime juice and mix it together. If using a canned mix, you can skip this step.
Mix Everything Together
In a 1½ quart baking dish, mix together the cauliflower rice, diced tomato blend, and salt until well combined.
Bake The Mexican Cauliflower Rice
Cook the cauliflower rice mixture in the oven, stirring about halfway through. Then, sprinkle on fresh cilantro and optional red pepper flakes when ready to serve.
This cauliflower rice is so convenient because you don’t even need to dry out the cauliflower or drain the liquid from the tomatoes. The liquid will evaporate in the oven, leaving you with the perfect side dish.
What To Serve With Keto Cauliflower Rice
Grilling is my cooking method of choice in the summer. In that case, I season the meat with my low-carb taco seasoning.
You could also enjoy it along with this Mexican zucchini and beef skillet for a meal that’s full of veggies and flavor.
