Creamy Cauliflower Mash Casserole

Creamy Cauliflower Mash Casserole brings the cozy feel of mashed potatoes with a lighter, veggie-forward profile. Rich cream cheese and nutty Parmesan make the mash silky and full-bodied, while a Cheddar blanket bakes to a bubbly, golden cap. Serve it as a comforting side for weeknight dinners or as a holiday table companion.
