# Expert Advice:

01 -
  • The homemade cheese sauce comes together in minutes but tastes like it simmered for hours
  • Its pure comfort food that somehow feels fancy enough for company
  • Leftovers reheat beautifully, if they even make it that far
02 -
  • The sauce will seem thin but it thickens as it bakes, so dont be tempted to add more flour
  • Let the dish rest for 5 minutes before serving so the sauce sets slightly
03 -
  • Grate your own cheese instead of buying pre-shredded for a smoother sauce
  • Warm your milk slightly before adding it to prevent the sauce from breaking
