Low Carb Cauliflower Mexican Rice – A Restaurant Favorite Remade!
At Mexican restaurants I often skip the rice—not because it lacks flavor, but because it’s usually greasy and calorie-dense. I’d rather enjoy chips and salsa. This cauliflower Mexican rice gives you all the familiar Mexican flavors without the heaviness. It’s light, bright, and ideal for anyone following Whole30, paleo, or a low-carb lifestyle.

Cauliflower is incredibly versatile. I first discovered cauliflower pizza crust and kept experimenting—mashed cauliflower for a potato alternative, cauliflower “fried rice,” and now this Mexican-style cauliflower rice. It’s one of the best uses yet: flavorful, easy to make, and much more nutrient-dense than white rice.

If you’re searching for a satisfying Whole30 side dish to replace bland salads and steamed veggies, this cauliflower Mexi rice is a great option.

Whole30 Mexican Rice Serving Suggestions
- Create a light burrito bowl: top the cauliflower rice with grilled meat, salsa, and avocado.
- Stir in scrambled eggs and finish with avocado for a quick breakfast or brunch.
- If you’re not following Whole30, use this cauliflower rice in quesadillas or burritos as a lower-carb alternative to traditional rice.

How to Make Cauliflower Rice
Ricing cauliflower is simple. Break the cauliflower into florets, then pulse half the head at a time in a food processor for 10–12 seconds until the pieces resemble rice grains. You can also finely chop by hand, but a food processor is much faster. Avoid over-processing so the cauliflower doesn’t become mushy and release excess water.

Calories: 77 kcal (per serving)
Ingredients
- 1 medium head cauliflower
- 1 tablespoon olive oil
- 1 onion, minced
- 2 cloves garlic, minced
- 1 carrot, chopped
- 1 cup peas (use snap peas or omit for strict Whole30)
- 3 tablespoons coconut aminos
- 1 1/2 teaspoons sea salt
- 1 1/2 teaspoons dried oregano
- 1 1/2 teaspoons ground cumin
- 1/2–1 teaspoon chili powder, to taste
- 1/4 cup tomato paste
- 2 limes
- Cilantro, chopped, for garnish
Instructions
- Break apart the cauliflower and rice half the head at a time in a food processor. Set aside.
- Heat olive oil in a large wok or skillet over medium-high heat. Sauté the onion and garlic until soft.
- Add the chopped carrot and peas and continue cooking until the carrot softens.
- Stir in the spices and coconut aminos, mixing well with the vegetables.
- Add the riced cauliflower and tomato paste, stirring to coat the mixture lightly.
- Cook over medium-high heat for 8–12 minutes, stirring frequently, until the cauliflower is tender and excess moisture has evaporated.

Notes
Do not over-process the cauliflower—too fine will create a watery result. Use high heat while stir-frying to help evaporate excess liquid and achieve a texture closer to traditional rice.
