Authentic Parmigiano-Reggiano, or its delicious domestic counterparts, offer a nutty, savory flavor that elevates countless dishes. Proper storage is key to preserving its complex taste and firm texture, ensuring you get the most out of this culinary gem.
Storage Time
Hard, aged Parmesan cheese can last for several weeks to months in the refrigerator when stored correctly. Once opened, aim to consume it within 2-3 months for optimal flavor. Grated Parmesan has a shorter shelf life, typically 1-2 weeks in the fridge.
Temperature
Store Parmesan cheese in the refrigerator, ideally between 0°C and 4°C (32°F and 40°F).
Freezing
Yes, Parmesan cheese can be frozen to extend its shelf life significantly, though it may slightly alter its texture, making it more crumbly upon thawing. For best results, grate the cheese before freezing. Wrap it tightly in plastic wrap, then place it in a freezer-safe bag or airtight container. Thaw frozen Parmesan in the refrigerator overnight. It's best used in cooked dishes after thawing, as its texture might not be ideal for grating fresh.
Signs of Spoilage
- Visible mold growth (any color other than the natural white or pale yellow of the cheese).
- A sour or ammoniated smell, indicating bacterial activity.
- A slimy or sticky texture on the surface of the cheese.
