Quick answers

Can you freeze parmesan cheese? Yes, you can freeze grated parmesan cheese or parmesan cheese wedges or blocks. Place parchment paper between cheese slices before freezing.

Can you freeze mozzarella cheese? Yes, you can freeze mozzarella cheese. For best results, freeze mozzarella cheese blocks, shreds or slices in air-tight packaging.

How long does parmesan cheese last in the freezer? Properly frozen parmesan cheese will last 6 to 8 months in the freezer before quality starts to decline. Use within 3 months for best flavor.

How long does mozzarella cheese last in the freezer? Frozen mozzarella cheese will maintain quality for 2 to 3 months in the freezer. For optimal freshness, use frozen mozzarella within 1 month.

Freezing Parmesan Cheese

Parmesan cheese, known for its hard, granular texture and savory umami flavor, can be frozen for later use. Here are some tips for freezing parmesan cheese:

Buy a block of parmesan cheese and grate it yourself before freezing. Pre-grated parmesan has anti-caking agents that can cause it to get gummy when frozen.
Divide grated parmesan into portions and place in freezer bags or airtight containers, removing as much air as possible. Flatten bags to freeze flat for efficient storage.

Freeze wedges or chunks of parmesan in parchment paper, plastic wrap or aluminum foil to protect the cheese from absorbing odors from the freezer.
Label everything with the date before freezing. Parmesan can be kept frozen for 6 to 8 months.
Thaw parmesan cheese gradually in the refrigerator overnight. Let come to room temperature before using for best texture.

The milk proteins and fat in parmesan make it suitable for freezing. However, freezing can still impact the taste and texture somewhat. Thawed parmesan may be crumbly or gritty, and it can become salty and pungent with prolonged freezing. For best quality and flavor, use frozen parmesan within 3 months.

Why Freeze Parmesan Cheese?

Freezing helps extend the shelf life of parmesan cheese beyond typical refrigerator storage. Here are some of the main advantages of freezing parmesan cheese:

Makes parmesan last longer – Freezing can keep parmesan edible for up to 8 months compared to 3-4 weeks in the fridge.

Reduces food waste – Stock up on parmesan when it’s on sale and freeze the excess to use later.
Preserves flavor – Slows the aging process so parmesan flavor stays intact longer.
No preservatives needed – Freezing preserves parmesan without adding preservatives.

Easy to thaw – Parmesan thaws quickly in the refrigerator when needed.

Overall, freezing gives you more time to use up parmesan cheese while minimizing waste and loss of flavor quality over time.

Freezing Mozzarella Cheese

Mozzarella, known for its soft, creamy texture and mild milky taste, can also be frozen successfully with proper methods. Here are some tips for freezing mozzarella cheese:

Cut or shred mozzarella cheese into portioned sizes before freezing for easier use. Freeze in air-tight bags or containers.
Wrap mozzarella balls or blocks in plastic wrap or parchment paper before freezing.
Exclude as much air as possible and press plastic wrap against the surface of the cheese.

Label everything with the date and use frozen mozzarella within 2-3 months for best quality.
Thaw frozen mozzarella gradually in the refrigerator. Allow to come to room temperature before serving.

The high moisture content of fresh mozzarella makes it more prone to textural changes during freezing. Thawed mozzarella may have a dry, crumbly texture and release more water. Low-moisture mozzarella freezes better. For optimal flavor and texture, use frozen mozzarella within 1 month.

Why Freeze Mozzarella Cheese?

Freezing gives mozzarella cheese much longer lifespan compared to refrigerating. Here are some key reasons to freeze mozzarella cheese:

Extends shelf life – Freezing keeps mozzarella edible for 2-3 months instead of 1-2 weeks refrigerated.
Avoid waste – Buying mozzarella in bulk is cheaper. Freeze extras to use later.

Preserve freshness – Slows aging and bacterial growth to maintain quality longer.
No preservatives – Freezing mozzarella requires no chemical preservatives.
Ready when needed – Thaw mozzarella overnight in the fridge to use in recipes.

Freezing is ideal for having mozzarella cheese ready for pizzas, casseroles, appetizers and other recipes for months to come.

Can You Refreeze Thawed Cheese?

It’s best not to refreeze parmesan or mozzarella cheese once thawed. Refreezing cheese can negatively impact the taste, texture and overall eating quality. Here are some downsides to avoid by not refreezing thawed cheese:

Dry, crumbly texture – Moisture is lost when ice crystals form during refreezing.

Grainy, gritty consistency – Cheese proteins degrade and crystallize.
Less flavor – Fats can oxidize causing rancid, bitter flavors.
Growth of bacteria – Harmful microbes thrive in repeatedly thawed cheese.

Unappealing color changes – Yellow or white color fades, turns gray.

For best quality and food safety, either use thawed parmesan or mozzarella cheese right away or discard any leftover thawed cheese. Do not attempt to refreeze.

How to Store Thawed Cheese

Instead of refreezing cheese after thawing, store any remaining thawed cheese in the refrigerator and use within a few days. Here are some storage guidelines:

Place thawed cheese in an airtight container or resealable plastic bag.
Exclude as much air as possible before sealing and keep refrigerated at 40°F or below.
Label the container with the date the cheese was thawed.

Use within 5 days for hard cheeses like parmesan, 3-4 days for soft cheeses like mozzarella.
Avoid freezing again to maintain the best quality and safety.

Properly stored in the fridge, thawed cheese will retain its texture and flavor for a short time before quality deteriorates. Discard moldy or unappealing cheese.

Signs Cheese Has Gone Bad When Thawed

Check thawed cheese carefully before eating. Here are some signs parmesan or mozzarella cheese has spoiled and should be discarded:

Mold growth – Discard moldy cheese even if only one spot.
Dry, crumbly texture – Extremely dry, crumbly or gritty cheese.

Shriveled appearance – Shrunken, sunken, deflated or sagging.
Yellow or brownish color – Severe discoloration.
Ammonia or sour smell – Strong unpleasant odors.

Slimy texture – Unusual stickiness or sliminess.
Off or bitter taste – Noticeably unpleasant flavors.

When in doubt, remember the old saying “When in doubt, throw it out” applies to thawed cheese too. Don’t risk getting sick from eating spoiled cheese.

Conclusion

Both parmesan and mozzarella cheese can be frozen for prolonged storage. Freezing stops the aging process to maintain quality longer without using preservatives. However, freezing can negatively affect cheese texture and flavor over time. For best results, use frozen parmesan cheese within 3 months and frozen mozzarella cheese within 1 month. Thawed cheese should not be refrozen – either use promptly or discard. Follow proper freezer storage and food safety practices to enjoy your favorite cheeses while minimizing waste.
