Understanding the Risks of Leaving Lasagna Out
Before delving into the specifics of lasagna storage, it is crucial to comprehend the potential hazards associated with leaving it out at room temperature. The primary concern lies in the growth of harmful bacteria, which can thrive in the warm and moist environment of lasagna.
