EQUIPMENT NEEDED

INGREDIENTS
- 1 large cauliflower head (4-6 cups riced) or 24 oz pre-riced
- 1 medium onion, finely chopped (150g)
- 2-3 garlic cloves, minced
- 1-2 jalapeños, finely chopped (omit for mild version)
- 2 roma tomatoes, diced (200g) (or 1 cup canned diced)
- 1 red bell pepper, diced (optional but adds great color)
- 2-3 tablespoons olive oil (30-45ml)
- 1½ teaspoons ground cumin
- 1 teaspoon smoked paprika
- ½ teaspoon salt (adjust to taste)
- ¼ teaspoon black pepper
- ¼ cup vegetable broth (60ml) (optional for moisture)
- ¼ cup fresh cilantro, chopped
- 2 tablespoons fresh lime juice
- Optional garnishes: avocado, cheese, sour cream
METHOD
- Rice your cauliflower by pulsing florets in food processor until they resemble rice grains.
Don’t overprocess – you want rice-sized pieces, not mush. - Heat olive oil in large skillet over medium-high heat.
- Sauté aromatics by adding onion and cooking for 2-3 minutes until translucent.
- Add garlic and jalapeños, stirring constantly for 30 seconds until fragrant.
Watch carefully – garlic burns quickly! - Toss in tomatoes and bell pepper with cumin, paprika, salt, and pepper.
Cook for 3-4 minutes until tomatoes start breaking down. - Add riced cauliflower and stir everything together thoroughly.
- Pour in broth if using, then cook for 5-7 minutes, stirring occasionally.
Target texture: tender but still has bite, not mushy. - Remove from heat and stir in cilantro and lime juice.
- Taste and adjust seasoning with more salt, pepper, or lime.
- Serve immediately while hot with your favorite garnishes.
CRUCIAL TIPS
- Don’t overcook the cauliflower – it goes from perfect to soggy fast
- Pre-riced cauliflower works great but may need less cooking time
- Squeeze excess moisture from fresh tomatoes to prevent soggy rice
- Medium-high heat is key – too low and vegetables won’t develop flavor
STORAGE & SCALING
Storage: Refrigerate leftovers up to 3 days in airtight container.
Heads up – reheated cauliflower can get a bit smelly, but tastes fine.
Reheating: Add splash of broth and heat gently in skillet or microwave.
Doubling recipe? Cook in batches to avoid overcrowding the pan.
COMMON MISTAKES TO AVOID
- Over-processing cauliflower into powder
- Adding too much liquid – cauliflower releases water as it cooks
- Skipping the aromatics sauté – this builds your flavor base
- Cooking on too high heat – burns garlic and spices
GAME-CHANGING VARIATIONS
- Protein boost: Brown 1 lb ground turkey or beef first, set aside, then add back at the end
- Bean addition: Stir in ½ cup black beans during last 2 minutes (adds ~8g carbs per serving)
- Cheese lovers: Top with Mexican cheese blend while hot
- Meal prep version: Skip cilantro and lime until serving to maintain freshness
Spice levels:
- Mild: Skip jalapeños, use sweet paprika
- Medium: Use 1 jalapeño, add pinch of chipotle powder
- Hot: Include jalapeño seeds, add diced serrano pepper
This Mexican cauliflower rice pairs perfectly with grilled chicken, fish tacos, or as a base for burrito bowls.
The best part? You’ll get all those bold Mexican flavors while keeping your carbs under 6g per serving.
I’ve made this recipe dozens of times, and the key is really not overthinking it – simple ingredients, proper timing, and you’re golden.
