# Expert Advice:

01 -
  • The mushroom caps become little edible bowls, holding all that cheesy chicken goodness like a hug on a plate
  • Everything cooks in one pan, and you probably have most of these ingredients lurking in your fridge right now
02 -
  • Removing the gills isn't strictly necessary, but they can release a dark liquid that makes your final dish look less appealing
  • Don't skip brushing the mushroom exteriors with oil, or they'll shrivel and dry out instead of roasting into something velvety
03 -
  • Broil for the last 2 to 3 minutes if you want that cheese to get golden and slightly crisp on top
  • Pat the mushroom caps dry with paper towels before oiling them, otherwise they'll steam instead of roast
