How to make keto cauliflower rice
June 15, 2026 · 3 min read
Cauliflower rice fails for one reason: excess moisture. Cauliflower holds a lot of water, and if it goes into the pan wet, it steams into a dense, watery mass instead of cooking into separate, fluffy grains. Squeeze it thoroughly before it hits the heat and the texture problem disappears.
Ingredients
- 1 small head cauliflower (about 500g), or 2 cups pre-riced cauliflower
- 1 tbsp butter or olive oil
- Salt and black pepper
- Optional: garlic powder, fresh herbs, lemon zest
Steps
- If using a whole head: cut into florets, then pulse in a food processor until it resembles rice. Don't over-process — a few pulses, not a puree. A box grater works too.
- Spread the riced cauliflower on a clean kitchen towel and squeeze out as much moisture as possible. This is the step most people skip. Skip it and you get mush.
- Heat butter or oil in a large skillet over medium-high heat.
- Add the cauliflower and cook, stirring occasionally, for 6–8 minutes until tender and starting to color at the edges. Don't stir constantly — let it sit and dry out.
- Season with salt, pepper, and any optional flavourings. Serve immediately.
The technique
A food processor or box grater both produce good rice. The food processor is faster; the grater gives slightly larger pieces that hold together better under saucy dishes. Either way, pulse or grate until the pieces are rice-sized, not smaller.
In the pan, the goal is dry heat. Medium-high, not medium — you want evaporation, not steaming. Stir occasionally rather than constantly. Two or three minutes of contact with the pan between stirs lets the moisture cook off and the edges get a little color, which adds flavor.
Variations
Plain cauliflower rice is a blank slate. A few directions that work well:
- Garlic butter: add a clove of minced garlic with the butter, cook 30 seconds before adding the cauliflower
- Lemon herb: finish with lemon zest and chopped parsley or chives
- Fried rice style: add a scrambled egg in the last minute, a splash of soy sauce or tamari, and sesame oil — goes well under the shrimp stir-fry
- Spiced: cumin and coriander if serving under a spiced protein
Net carbs
A serving runs about 4g net carbs, versus roughly 45g for the same volume of white rice. It fits under a standard keto ceiling without making a dent.
Pair it with anything from the recipe library — the beef bowl and shrimp stir-fry both work on top of it. Log "cauliflower rice, one cup" in Copper Keto Companion and it tracks the 4g net carbs alongside whatever you're serving it with.
Common questions
Is cauliflower rice actually low carb? Yes — about 4g net carbs per cup cooked, versus 45g for white rice. That difference is what makes it a practical keto substitute rather than a compromise.
Does it taste like real rice? Not exactly, but it absorbs flavors and sauces well. Served under something saucy or spiced, most people stop noticing the difference within a few meals.
Can I make it ahead? The riced, squeezed cauliflower keeps raw in the fridge for up to two days. Cooked cauliflower rice is fine for meal prep but softens a little on reheating — reheat in a dry pan rather than a microwave to keep some texture.
Can I use frozen cauliflower rice? Yes, but squeeze out even more moisture — frozen cauliflower releases a lot of water as it thaws. Cook from frozen over higher heat, stirring less.
