Tips & Techniques for the Best Cheesy Broccoli Cauliflower Rice

  • You can reference this post on How to Rice Cauliflower, if needed.
  • Shred the cheese from a block rather than using pre-shredded bagged cheese. Cheese from a block melts better and doesn’t contain any added starches.
  • Use fresh cauliflower and broccoli rather than frozen for the best results.
  • Add in some cooked chicken, crumbled bacon, sausage, or diced ham for added protein, flavor, and heartiness!
  • Store any leftovers in an air-tight container in the refrigerator. Use within 3-5 days.


  • Can you substitute the heavy cream with half and half or milk? Yes, just be aware that the cheese sauce may be on the thinner side should you choose not to use heavy cream.
