Cauliflower rice has become the default low-carb stand-in for regular rice — and the numbers back it up.
The carb math
One cup of cooked cauliflower rice has roughly 3g net carbs (5g total carbs, 2g fiber). Compare to one cup of cooked white rice at 44g net carbs. That's a ~93% reduction.
But brand matters
Frozen "cauliflower rice blends" sold in supermarkets often contain other ingredients to bulk out the bag and reduce cost:
- Riced sweet potato (~10g net carbs per cup)
- Lentils (~12g net carbs per cup)
- Quinoa (~15g net carbs per cup)
- Plain rice mixed in (varies wildly)
Check the ingredient list before assuming a frozen bag is the low-carb option you want. Pure cauliflower rice should list cauliflower and nothing else.
DIY in 3 minutes
A small head of cauliflower, pulsed in a food processor for 10 seconds, gives you about 4-5 cups of rice for $1-2. Store unused portions in the fridge for 5 days.
How to use it
Cauliflower rice is bland on its own — that's a feature. Sauté in butter with garlic and salt, finish with lemon zest, and it carries any sauce or stir-fry. The scanner detects cauliflower rice and counts the carbs correctly when it's plated visibly.
