# Expert Advice:

01 -
  • The creamy Dijon sauce ties everything together in a way that feels fancy but takes about ten minutes to assemble
  • Leftovers reheat beautifully, making it the perfect gift for a busy friend or your future self
02 -
  • Do not skip the resting period, this needs those few minutes to firm up or it will slide apart when you serve it
  • If your panko starts browning too quickly, tent the dish with foil for the last ten minutes
03 -
  • Grate your own cheese from blocks instead of buying bags, the anti caking coating on pre shredded cheese prevents smooth melting
  • Room temperature ingredients combine more easily, so take everything out of the fridge about 20 minutes before you start
