FAQs
Can I use fresh cauliflower instead of cauliflower rice?
Yes, you can finely chop fresh cauliflower to mimic cauliflower rice, but cooking time may be slightly longer to ensure it softens properly.
What is the best cream sauce to use in this casserole?
A simple cream of mushroom or cream of chicken soup works well, but a homemade white sauce made with butter, flour, milk, and seasoning provides a richer, more customizable flavor.
