# Expert Advice:

01 -
  • You get all the comfort of a classic beef casserole without the heavy pasta
  • The cauliflower rice soaks up all those savory beef juices and spices perfectly
  • Leftovers reheat beautifully for lunch the next day
02 -
  • Draining excess fat from the beef keeps the casserole from becoming greasy but do not go overboard or you will lose flavor
  • Letting the casserole rest for 5 minutes is essential or it will be too loose when you try to scoop it
  • Frozen cauliflower rice releases more water than fresh so you may need to cook it an extra minute or two
03 -
  • Rice your own cauliflower from a fresh head for the best texture it only takes a few minutes in a food processor
  • Grate your own cheese instead of buying pre shredded since the anti caking agents in bagged cheese can make it grainy
