# Expert Hints:

01 -
  • The whole thing comes together in under an hour but tastes like it simmered all afternoon
  • It's the perfect excuse to buy a rotisserie chicken and call it cooking
  • The leftovers somehow taste even better the next day, if they last that long
02 -
  • I once skipped letting it rest and ended up with a runny mess on my plate, lesson learned
  • The panko needs to be thoroughly mixed with butter or you'll get dry spots instead of golden crunch
  • Don't be afraid to let it go an extra 5 minutes if you want those deep brown edges
03 -
  • Buy an extra rotisserie chicken and shred the rest for salads or tacos during the week
  • Room temperature cheese melts more evenly, so take it out of the fridge while you prep
