Tips for the Best Cauliflower Rice
- Don’t overcrowd the pan – Ensures even cooking and prevents sogginess.
- High heat – Helps evaporate moisture for a better texture.
- Fresh garlic – Powder won’t give the same depth of flavor.
- Toast the mushrooms – Let them brown for maximum umami.
Common Mistakes to Avoid
- Overcooking – Cauliflower rice should be tender but not mushy.
- Skipping the lemon – Brightens the dish and balances flavors.
