How to Make "Cauliflower Rice"

  1. Cut florets from a head of cauliflower and put them in a food processor.

  2. Pulse until the cauliflower pieces are the size of grains of couscous or rice.

  3. For coarser grains, use the large shredding disk on the food processor or use a box grater.

Recipe Variations

  • If you're not feeling chicken, turkey breast cutlets are another lean option.
  • If you'd like to add more vegetables, sauté some mushrooms or onions along with the chicken and add them to the casserole.
  • Or, for a burst of color, toss some minced pimientos with the cauliflower and herb mixture.
  • To make a saucier casserole, replace the cream with 1 cup of this basic medium white sauce; stir it into the rice along with half of the shredded cheese. Use the remaining 1/2 cup of shredded cheese for the topping.
  • Grated cauliflower makes an excellent rice or couscous replacement. Use a box grater or food processor to grate the cauliflower (instructions above).
  • A combination of cauliflower and broccoli is another option, offering extra color and flavor.
