If you’ve ever found yourself staring at a giant block of Parmesan Reggiano from Costco, wondering how to keep it fresh for as long as possible, you’re not alone! This beloved hard cheese can last for months with the right care. Here’s everything you need to know to extend its life and preserve its flavor.
1. The Best Packaging for Parmesan Reggiano
One of the most critical factors in storing Parmesan is the type of wrap you use. Plastic wrap might seem like the easiest solution, but it can trap moisture, accelerating mold growth. Instead, try these options:
- Parchment or wax paper: These allow the cheese to breathe while keeping excess moisture at bay.
- Cheese storage bags: Specialty bags made from breathable materials (available on Amazon) are excellent for preserving texture and flavor.
- Beeswax wraps: Eco-friendly and reusable, beeswax wraps are perfect for creating a breathable seal.
After wrapping, place the cheese in a zip-lock bag or an airtight container to protect it from fridge odors.
2. Where to Store Parmesan Reggiano
The refrigerator is your best bet for long-term storage. Keep the cheese in the deli or vegetable drawer, which tends to maintain a slightly cooler and more stable temperature. Avoid storing it near strong-smelling foods like onions, as Parmesan can absorb odors.
3. The Do’s and Don’ts of Cheese Hygiene
How you handle Parmesan makes a significant difference in preventing mold:
- Do: Use clean utensils when cutting or grating the cheese.
- Don’t: Touch it with bare hands. Oils and bacteria from your fingers can create mold-friendly spots.
- Do: Rewrap the cheese after every use with fresh parchment or wax paper.
4. To Freeze or Not to Freeze?
Freezing Parmesan is a hotly debated topic. While it can change the texture slightly (making it more crumbly), freezing is a practical option if you don’t plan to use the cheese quickly. To freeze:
- Cut the block into smaller portions.
- Vacuum seal or wrap tightly in parchment and place in a freezer bag.
- Thaw portions as needed—grated Parmesan can be used straight from the freezer!
5. Tips to Reduce Waste
- Save the rind! Parmesan rinds add incredible depth to soups and stews. Store them in the freezer for easy access.
- Grate in advance: If you use grated Parmesan regularly, shred the entire block and freeze portions in airtight containers.
6. What to Do if Mold Appears
Don’t panic if mold develops—it’s often only on the surface of hard cheeses like Parmesan. Simply cut away the affected area (about 1 inch around the mold), ensuring the knife doesn’t touch the mold, and enjoy the rest.
Final Thoughts
Parmesan Reggiano is a culinary treasure, and with these tips, your Costco-sized block will stay fresh and flavorful for months. Whether you use parchment paper, freeze portions, or invest in cheese storage bags, the key is proper handling and consistent care.
So, next time you see that massive Parmesan block at Costco, don’t hesitate—stock up and savor the cheese at its best!
