Storage and Reheating Solutions

For the best experience with leftovers:

  • Wrap uneaten portions in parchment paper before foil
  • Reheat in a pan rather than microwave to maintain crispiness
  • Store components separately if prepping ahead
  • Let refrigerated ingredients reach room temperature before assembling

Troubleshooting Common Issues

If bread browns too quickly:

  • Lower heat and cook more slowly
  • Use thicker bread slices
  • Keep a close eye on the first side
  • Start with a cold pan rather than preheated

If cheese isn't melting properly:

  • Cover pan with lid for 30 seconds
  • Grate or slice cheese thinner
  • Allow cheese to come to room temperature
  • Use freshly grated rather than pre-shredded
