How Long Can Cheese Generally Be Left Out of The Fridge Before It Gets Dangerous?

Cheese is a staple at any party, whether it's perched on a cracker or adding flair to a charcuterie board. The problem is: you can't keep cheese in the fridge at a party without constantly running back and forth to the kitchen, missing out on the fun with your guests. So, the question arises: how long can you leave cheese out before it starts endangering you and your guests?

How Long Can Cheese Be Left Out, Generally?

Generally, cheese can be left out at room temperature for about two hours before it starts to pose a risk. This guideline is recommended by food safety experts to prevent the growth of harmful bacteria. Beyond this time frame, cheese can begin to sweat, soften, and develop an off taste and texture, making it less enjoyable and potentially unsafe. So, if you’re hosting a party, it’s a good idea to set out smaller amounts of cheese and replenish the platter throughout the evening.

Hard vs. Soft Cheeses: How Long Can They Last?

When it comes to how long different types of cheese can sit out, hard cheeses have a significant advantage over soft cheeses. Hard cheeses like cheddar, Gouda, and Parmesan can safely sit out for up to four hours due to their lower moisture content, which inhibits bacterial growth. On the other hand, soft cheeses such as Brie, Camembert, and fresh mozzarella should not be left out for more than two hours. Their higher moisture content makes them more susceptible to bacterial contamination, so it’s best to keep these types of cheese chilled until serving.

The Safest Cheese Choices for a Party

If you’re looking for cheeses that can safely be left out for extended periods at a party, go for hard cheeses and aged varieties. Cheeses like aged Gouda, Parmesan, and Pecorino Romano are great options because they are less likely to spoil quickly. These cheeses not only hold up well at room temperature but also add robust flavors to your cheese board, ensuring that your guests can enjoy them throughout the event without worry.

How to Tell If Cheese Has Gone Bad

Knowing when cheese has gone bad is crucial for both taste and safety. If you notice any mold that wasn’t originally part of the cheese, it’s time to discard it, especially for soft cheeses. For hard cheeses, you can sometimes cut away the moldy part and consume the rest. Bad cheese often has a sour or rancid smell, a change in texture (such as becoming overly soft or hard), and an off taste. If the cheese appears oily, discolored, or has an ammonia-like smell, it's best to err on the side of caution and throw it out.
