Expiration & Storage Tips
When does mascarpone cheese expire?
When unopened, mascarpone cheese can last one to two weeks past the printed date on the package if stored correctly in the refrigerator. Once opened, it is best to consume the cheese within a few days, no longer than a week. As for freezing, while it is possible to freeze mascarpone cheese, it may alter the texture making it less smooth and creamy once defrosted. It is generally recommended to use it within two months if frozen.
How do you tell if mascarpone cheese is bad?
When mascarpone goes bad, the indicators are quite distinctive. The cheese may develop a sour smell somewhat similar to sour cream. Rancid mascarpone cheese may also form a tough yellowish crust on the surface. In some cases, you might notice mold growth in different hues – blue, green, or white. Any of these signs mean it’s time to toss it out.
Tips for storing mascarpone cheese to extend shelf life
• Always store mascarpone cheese in the refrigerator. It's best kept at temperatures between 35°F and 40°F.
• Try to keep the cheese in an airtight container or wrap it tightly in cling film. This will keep it from drying out or absorbing other odors in the fridge.
• If you have lots of cheese left and can't consume it right away, consider freezing it. Just bear in mind, this may change the texture. Freeze in portion-sizes you're likely to use in recipes.
• Mascarpone cheese should not be left at room temperature for more than two hours. Doing so increases the risk of bacterial growth.
