Butter is a staple in many kitchens, but when left out at room temperature for extended periods, it raises questions about safety. If you’ve ever set butter aside for baking and forgotten about it for a week, you might be wondering—should you use it or toss it? Let’s break it down.
Does Butter Go Bad at Room Temperature?
Butter is unique compared to other dairy products because it has a high fat content and low moisture, making it less prone to bacterial growth. Unsalted butter, however, is more perishable than salted butter because salt acts as a preservative.
How Long Can Butter Be Left Out?
