# Expert Advice:

01 -
  • Everything cooks in one dish, meaning less cleanup and more time enjoying your evening
  • The creamy sauce binds potatoes, chicken, and broccoli into something greater than the sum of its parts
02 -
  • Overcooking the broccoli during steaming is the most common mistake. Three minutes is usually perfect.
  • The sauce thickens in the oven, so it may look thinner than you expect when mixing everything together.
03 -
  • Cut your potatoes into uniform 1 inch cubes so some pieces dont turn to mush while others stay undercooked
  • Grate your own cheese from blocks instead of buying pre shredded cheese melts so much better without anti caking agents
