Read my complete guide on how to make homemade cauliflower rice - 4 different ways, with and without a food processor. Included are some tasty variations for to use this low-carb rice substitute.
Wash and trim the head, trimming off any brown spots from the florets.
Cut the head in half and remove the woody center. You can also cut the head into quarters and then cut out the center.
Cut the large florets into smaller pieces if you're using a food processor, blender or are cutting by hand. Otherwise, leave them in larger pieces if grating.
Food processor method
If using the S blade, place the florets in the food processor and pulse until they're chopped into fine pieces. It may be better to work in batches to produce more uniform 'grains'.
If using the grater attachment, turn on the food processor and feed the florets through the tube. Depending on the capacity of the processor and size of your head, you may need to empty the bowl a couple times.
Using a box grater or cheese grater
Cut the florets into large or medium-sized pieces and grate on the side with the large-sized holes.
Using a blender
Without water: working in batches, add about 2 cups of florets to the blender and pulse until small pieces are formed.
With water: add 2-3 cups of florets to the blender and pour in just enough water to immerse them. Pulse until they resemble grains of rice, then strain. Remove extra moisture by squeezing the 'rice' with a paper towel after blending.
Using a knife
Using a large chef's knife, chop the prepared florets into tiny pieces.
