Yes, you can put cheese in the freezer to extend its shelf life, though texture changes make most thawed varieties best suited for cooking.
Cheese is a staple in many kitchens, but it is also one of the first items to spoil if not used quickly. The price of dairy continues to climb, making food waste a costly problem for households. Many home cooks wonder if the freezer is a viable option to save leftover blocks or take advantage of bulk sales at the grocery store. The answer relies heavily on the type of cheese you have and how you plan to use it later.
Freezing pauses the aging process effectively. However, the formation of ice crystals affects the protein structure of dairy products. This guide details exactly which cheeses handle the cold well, which ones crumble under pressure, and the specific steps to ensure your dairy remains delicious after thawing.
The Science Behind Freezing Cheese
Understanding what happens inside the cheese wrapper helps manage expectations. Cheese is a matrix of fat, protein, and water. When you place cheese in the freezer, the water content inside expands as it turns into ice. These sharp ice crystals puncture the protein structure that holds the cheese together.
Upon thawing, the ice melts, but the protein structure does not snap back to its original form. This structural damage is why previously frozen cheese often has a crumbly or mealy texture. The moisture that was once evenly distributed may seep out, leaving the block drier than before. While the flavor usually remains stable, the mouthfeel changes significantly.
High-moisture cheeses suffer the most from this crystalline expansion. Harder, aged cheeses with less water content maintain their integrity much better. Knowing this distinction saves you from ruining a perfectly good wedge of Brie or a delicate fresh ricotta.
Which Cheeses Freeze Well And Which Do Not
Not all dairy is created equal when it comes to long-term cold storage. You need to categorize your cheese inventory before tossing it into the freezer drawer.
Hard And Semi-Hard Cheeses
These are the best candidates for freezing. Their lower moisture content means fewer ice crystals form, resulting in less damage to the texture. While they may become slightly more brittle, they remain perfectly usable.
- Cheddar: Freezes exceptionally well, especially colored varieties.
- Swiss: Holds up decently, though the eyes (holes) may collect moisture.
- Parmesan and Pecorino: These low-moisture options are freezer champions. You can store them as wedges or grated.
- Gouda: Aged Gouda fares better than young Gouda due to lower water content.
- Provolone: Freezes well, particularly the aged “Piccante” varieties.
Soft And Fresh Cheeses
This category requires caution. The high water content in these cheeses creates large ice crystals, leading to separation and a grainy texture upon thawing. The fats often separate from the liquids, creating a watery mess.
- Ricotta and Cottage Cheese: These often separate into curds and whey. Only freeze these if you plan to bake them into a lasagna where texture matters less.
- Cream Cheese: It becomes crumbly and grainy. However, it can still be whipped back into a decent consistency for baking cheesecakes or pound cakes.
- Brie and Camembert: Freezing ruins the blooming rind and turns the creamy interior into a grainy paste. Avoid freezing these if you want to eat them on a cheese board.
- Queso Fresco: Like ricotta, it loses its bounce and becomes dry.
Blue Cheeses
Blue cheese falls somewhere in the middle. The mold veins can lose some potency, and the texture becomes incredibly crumbly. Since blue cheese is often crumbled over salads or melted into sauces anyway, freezing is generally acceptable for this variety.
Step-By-Step Guide To Freezing Cheese Properly
Throwing the original store packaging directly into the freezer is a recipe for freezer burn. Plastic wrappers from the grocery store are designed for breathability in the fridge, not the harsh environment of a freezer. Follow these steps to protect your investment.
Freezing Blocks Of Cheese
Blocks have the best surface-area-to-volume ratio, which helps prevent drying out.
- Portion the block — Cut large blocks into pieces no larger than half a pound. Huge blocks freeze unevenly and are difficult to use later without thawing the whole thing.
- Wrap strictly — Wrap the cheese tightly in parchment paper or wax paper first. This allows the cheese to breathe slightly without drying out.
- Add a barrier — Wrap the parchment-covered cheese in a layer of heavy-duty aluminum foil or plastic cling wrap.
- Bag it up — Place the double-wrapped cheese into a freezer-safe heavy-duty zipper bag. Press out as much air as possible before sealing.
Freezing Shredded Cheese
Shredded cheese is convenient, but it clumps easily if not handled right.
- Add starch — If you shred your own cheese, toss it with a teaspoon of cornstarch or potato starch. This mimics the cellulose found in store-bought bags and prevents clumping.
- Flash freeze — Spread the shreds on a baking sheet and freeze for 20 minutes before bagging. This ensures the shreds remain loose.
- Seal tight — Transfer to a freezer bag and remove excess air.
Freezing Sliced Cheese
Slices tend to fuse together into a solid brick when frozen.
- Separate layers — Place a small square of parchment paper between each slice of cheese.
- Stack and wrap — Stack the separated slices, then wrap the entire stack in plastic wrap or foil before placing it in a freezer bag.
How To Defrost Cheese Safely
Thawing is just as critical as freezing. Rushing this process forces moisture out of the cheese too quickly, ruining the texture instantly. According to food safety guidelines regarding freezing, keeping food at a safe temperature during thawing is vital to prevent bacterial growth.
Use the refrigerator — Move the cheese from the freezer to the refrigerator at least 24 hours before you need it. A slow thaw allows the moisture to reabsorb into the protein matrix more effectively.
Keep the wrapper on — Do not open the packaging while the cheese is thawing. Opening it exposes the cold cheese to warm air, causing condensation to form on the surface. This moisture promotes mold growth and makes the cheese soggy.
Avoid the counter — Never thaw dairy products on the kitchen counter. The outer layers will reach the “danger zone” (40°F–140°F) where bacteria multiply, while the center remains frozen. This is both a safety risk and a texture killer.
Best Uses For Thawed Cheese
Since the texture changes, you should adjust how you use the product. If you try to slice thawed cheddar for a cracker, it will likely crumble and lack that smooth mouthfeel. Adjusting your culinary approach makes freezing cheese highly effective.
Cooking And Melting
Heat is the great equalizer. When cheese melts, the protein structure relaxes, and the textural defects caused by freezing disappear. Thawed cheese is excellent for:
- Macaroni and cheese: The sauce emulsion hides graininess.
- Casseroles: Lasagnas and baked ziti benefit from the melt.
- Grilled cheese sandwiches: The heat brings back the gooey consistency.
- Soups and sauces: Fondues or broccoli cheddar soups work perfectly.
Crumbling And Topping
Since the cheese is already prone to crumbling, lean into it. Use thawed hard cheeses like Parmesan or aged Gouda as toppings.
- Salad toppings: Crumbled blue cheese or shaved parmesan works well.
- Pizza: Shredded mozzarella melts uniformly on a pizza, masking any previous separation.
- Tacos and chili: The heat from the meat softens the cheese immediately.
Common Mistakes That Ruin Frozen Cheese
Even with the best intentions, small errors lead to wasted food. Avoid these pitfalls to ensure your supply lasts.
Freezing Original Packaging Unopened
Store packaging is rarely airtight enough for the freezer. The thin plastic allows cold air to penetrate, leading to gray, dry patches known as freezer burn. Always add that extra layer of foil or a heavy-duty bag.
Forgetting The Date
Cheese does not last forever, even in the freezer. While it remains safe to eat indefinitely if kept frozen continuously, the quality degrades after 3 to 6 months. Label every package with the type of cheese and the date you froze it. Rotate your stock so you use the oldest items first.
Refreezing Thawed Cheese
Once you thaw cheese, use it. Refreezing it damages the structure a second time, turning it into a flavorless, dry substance that refuses to melt properly. Only take out what you plan to use within a few days.
Can I Put Cheese In The Freezer If It Is Moldy?
You cannot freeze away mold. Freezing deactivates mold spores but does not kill them. Once the cheese thaws, the mold will continue to grow.
For hard cheeses, you can cut at least one inch around and below the mold spot, then freeze the remaining clean portion. For soft cheeses like cream cheese or ricotta, discard the entire container if you see mold, as the spores penetrate deep into the high-moisture interior. Freezing a contaminated product only preserves the contamination.
Key Takeaways: Can I Put Cheese In The Freezer?

➤ Texture changes are inevitable; use thawed cheese for cooking only.
➤ Double-wrap blocks in parchment and foil to prevent freezer burn.
➤ Thaw cheese slowly in the refrigerator for at least 24 hours.
➤ Shredded cheese requires cornstarch to prevent clumping in the cold.
Frequently Asked Questions
How long can I keep cheese in the freezer?
For best quality, use frozen hard cheese within six months. Soft cheeses should be used within three months. While they remain safe to eat beyond these times, the flavor may dull and the texture will become increasingly dry and crumbly, making them difficult to use even in cooked dishes.
Does freezing cheese change its nutritional value?
No, freezing does not alter the calorie count, protein, calcium, or fat content of the cheese. The only changes are physical, affecting moisture distribution and texture. You get the same nutritional benefits from thawed cheese as you do from fresh varieties.
Can I freeze store-bought bags of shredded cheese?
Yes, unopened bags of store-bought shreds freeze very well because they contain anti-caking agents like cellulose. Place the unopened bag directly into a thicker freezer bag for extra protection. Shake the bag vigorously before opening it after thawing to break up any clumps.
Is it better to grate cheese before or after freezing?
It is generally better to grate cheese before freezing if you plan to use it for melting. Grated cheese thaws faster and is ready to use immediately. Grating a thawed block can be messy because the cheese becomes brittle and may crumble in your hands or the grater.
What happens if I eat freezer-burned cheese?
Freezer-burned cheese is safe to eat, but it will taste unpleasant. The gray or white dry spots indicate moisture loss, leading to a stale, cardboard-like flavor. You can trim off the freezer-burned sections and use the remaining unaffected cheese for cooking.
Wrapping It Up – Can I Put Cheese In The Freezer?
You can put cheese in the freezer as a practical way to reduce waste and save money, provided you follow the right rules. Hard and semi-hard varieties survive the cold effectively, while soft cheeses often struggle. By double-wrapping your blocks and reserving the thawed product for your favorite hot recipes, you ensure that no wedge goes to waste. Treat your freezer as a short-term preservation tool rather than indefinite storage, and you will always have a ready supply of dairy for your next meal.
