Notes

  • Bring chicken to room temperature before cooking for even results.
  • Don’t overcrowd the pan — it prevents proper browning.
  • Sauté garlic briefly to avoid bitterness.
  • Use fresh lemon juice for the best flavor balance.
  • Grate cheese fresh for a smoother sauce.
  • Simmer longer to thicken; add broth to thin.
  • Reheat gently over low heat to prevent sauce separation.
