# Expert Suggestions:

01 -
  • The cauliflower rice soaks up all those spiced beef juices while keeping things light enough for seconds
  • That bubbly golden cheese crust on top creates the most incredible contrast to the tender savory filling underneath
02 -
  • Pat your cauliflower rice really dry if you are using frozen, otherwise you will end up with a watery casserole nobody wants
  • Letting it rest those 5 minutes seems pointless but it makes the difference between a neat slice and a sloppy mess on your plate
03 -
  • Use a box grater to make your own cauliflower rice from fresh heads, the texture is so much better than the pre bagged stuff
  • Room temperature sour cream mixes in more smoothly without leaving those little white pockets throughout
