Critical Success Points

  • Do not boil the cream when preparing the cheese sauce.
  • Watch the broiling to prevent the cheese from burning.
  • Sauté the zucchini over medium heat so they release their water without burning the garlic butter.

Safety Warnings

  • Handle the pan and oven with heat‑resistant gloves.
  • Be careful of hot butter splatters.
