For the best texture, avoid crowding the pan and resist the urge to stir constantly so the cauliflower can develop some color and a lightly toasted flavor. If using frozen riced cauliflower, thaw it completely and squeeze out as much liquid as possible before cooking. Choose a soy sauce, tamari, or coconut aminos without added sugar to keep the dish strictly keto. Leftover cauliflower fried rice stores well in an airtight container in the refrigerator for up to 3 days and reheats best in a hot skillet to restore its fried texture.
