# Expert Advice:

01 -
  • The beef becomes so tender it practically melts, and you don't have to babysit a hot stove for hours.
  • Your whole house smells incredible, and guests think you've been cooking all day when really you just prepped ingredients.
  • Leftovers turn into the best sandwiches, so you're basically getting two meals for the work of one.
02 -
  • Don't skip the searing step if you can—those browned bits add a depth that makes people taste the difference and wonder what you did differently.
  • Waxy potatoes are non-negotiable; russets will fall apart and make your liquid cloudy.
  • Fresh herbs are essential; dried herbs become dusty and bitter during eight hours of cooking, so if you only have dried, use half the amount and add them in the last hour.
03 -
  • Leftovers make extraordinary sandwiches the next day—pile the shredded beef on crusty bread with a spoonful of gravy and you've got something that might be better than the first meal.
  • If your slow cooker runs hot, eight hours on low might be too long; start checking at the six-hour mark to avoid overcooking.
