# Expert Tips:

01 -
  • The cauliflower rice soaks up all those savory beef juices while staying surprisingly light and fluffy
  • Its the kind of comfort food that leaves you satisfied without that heavy pasta coma afterward
02 -
  • Draining excess fat from the beef keeps the casserole from becoming greasy but dont go overboard or you'll lose flavor
  • Cauliflower rice releases water as it cooks so don't skip the step of cooking it down before adding the creamy elements
03 -
  • Grating your own cheese instead of buying pre-shredded makes a huge difference in how smoothly it melts
  • Letting the cauliflower rice cook down until most moisture evaporates prevents a watery casserole
