  • Using smaller, bite-sized mushrooms helps bake them into a crispier bite.
  • Choose another cheese, perhaps a good melting one.
  • These mushrooms may be prepared, sealed in an airtight container, and stored in the freezer or refrigerator until they are ready to bake; remove them from the fridge ahead of time to come to room temperature, or bake a few minutes longer in the oven.
