# Expert Advice:

01 -
  • Everything bakes in one dish so cleanup is almost nonexistent.
  • The crispy panko topping gives you that satisfying crunch without any frying.
  • It tastes like chicken parm but feels more like a hug in casserole form.
02 -
  • If your chicken pieces are thick, they might need an extra five minutes, so check the internal temp hits 165°F.
  • Do not cover the dish while baking or the topping will steam instead of crisp.
03 -
  • Use a glass or ceramic baking dish if you have one, it holds heat evenly and the edges get perfectly browned.
  • If the top is browning too fast, tent it loosely with foil for the last ten minutes.
