Can You Freeze Mozzarella Cheese?
Quick Answer
Yes, you can freeze mozzarella cheese, and the low moisture kind in a block or shredded keeps well for about 6 months when it is wrapped tightly with the air pressed out. Fresh mozzarella packed in water keeps for about 3 months, but it turns softer and a little grainy after thawing, so it belongs in cooked dishes where it melts. When you shred block mozzarella before freezing and thaw it slowly in the fridge, it melts smoothly over pizza, pasta bakes and garlic bread, just the way you want it to.
Does All Mozzarella Freeze the Same Way?
Mozzarella comes in two very different moods. Low moisture mozzarella is firm, pale and made for melting, and it shrugs off the freezer with barely a complaint. Fresh mozzarella is soft, milky and stored in water, and that extra moisture is exactly what freezing changes.
In the freezer, water inside the cheese forms crystals. In a firm block there is less water to cause trouble, so the texture survives well. In fresh mozzarella the crystals break the delicate curd, and the cheese thaws softer, wetter and a little grainy. The flavor stays pleasant, but the silky slice you wanted for a salad is gone.
Shredded mozzarella sits in the happy middle. It freezes quickly, portions easily and melts nearly as well as fresh. For most home cooks it is the best form to freeze, which is why the method below leans into shredding.
How to Freeze Mozzarella
Let the cheese stay in its opened package only until you wrap it properly. Cheese left in loose store packaging dries at the edges and picks up freezer smells, so give it a fresh tight wrap before it goes in.
- Pat the mozzarella dry with a clean towel or paper.
- Shred the block on the coarse side of a grater, or keep it whole.
- Toss shredded cheese with a small spoon of flour if bags tend to clump.
- Portion the cheese into bags sized for one pizza or one bake.
- Press out the extra air and seal each bag flat.
- For a whole block, wrap tightly first, then slip it into a bag.
- Label with the kind and date and freeze at 0°F.
Flat bags freeze fast and stack neatly. Pull out only what a meal needs and the rest stays sealed and cold. The same portion habit makes freezing shredded cheese of any kind easy to grab without thawing a whole lump.
If you freeze the block whole, expect to shred it after thawing. Very cold cheese grates cleanly while still a little firm, so you can even grate it straight from the fridge after a short rest.
What About String Cheese, Balls and Slices?
String cheese freezes surprisingly well because it is firm and low in moisture. Freeze the sticks in their wrappers, grouped inside one bag, and thaw them in the fridge for lunchboxes. The texture turns a touch firmer, but kids rarely complain.
Fresh mozzarella balls belong to the fresh rules. Freeze them drained and patted dry, in a bag with the air out, and plan to melt them after thawing. In salads they lose their silky bite, so save fresh balls for fresh eating and freeze only the extras you cannot use in time.
Sliced mozzarella freezes with a sheet of parchment between the slices so they separate easily later. The slices thaw quickly and suit cooked sandwiches, eggplant bakes and burgers where they melt into place.
How Long Does Mozzarella Keep in the Freezer?
Use low moisture mozzarella within about 6 months for the best melt and flavor. It stays safe longer while frozen solid, but the taste slowly dulls and dry edges can appear on a poorly wrapped block.
- Low moisture block: About 6 months, wrapped tightly.
- Shredded low moisture: About 6 months, in flat portioned bags.
- Fresh mozzarella balls: About 3 months, best melted after thawing.
- String cheese sticks: About 6 months in their wrappers.
- Sliced mozzarella: About 6 months with parchment between slices.

Thawing and Melting Frozen Mozzarella
Thaw mozzarella in the fridge, still sealed, so it softens slowly and stays safe. A bag of shredded cheese may thaw in a few hours, while a whole block can need most of a day. Once thawed, use it within a few days and keep it wrapped and cold.
Shredded mozzarella can also go onto a hot pizza almost frozen. Spread it while the oven heats and it will melt in place, though a short fridge thaw gives the most even melt. Fresh mozzarella that has been frozen should be drained well after thawing, because it releases liquid that can make a crust soggy.
Melt thawed mozzarella low and easy. Very high heat can turn it stringy and oily, while gentle heat keeps it smooth. In sauces, stir it in off the boil so it blends instead of clumping.
What Makes Mozzarella Turn Grainy?
- Freezing it in loose store wrap: Edges dry and smells creep in.
- Freezing fresh balls in their water: Extra liquid turns to ice and weeps later.
- Packing one giant bag: You thaw more than the meal needs.
- Skipping the label: Fresh and low moisture kinds get mixed up.
- Refreezing thawed cheese often: Each round makes the texture rougher.
- Thawing on the counter: Cheese should stay cold until it cooks.
A quiet mistake is freezing mozzarella that already smells sour. Freezing pauses time but never reverses it, so freeze cheese while it still smells sweet and milky.
Best Uses for Frozen Mozzarella
Frozen mozzarella was born for melted jobs. Pizza is the headline use, followed by lasagna, baked ziti, stuffed shells, garlic bread and cheesy casseroles. Shredded bags make weeknight cooking fast, because the cheese goes from freezer to fridge to bubbling dish with no grating session.
Fresh mozzarella that has been frozen still earns its place in cooked food. Tuck it into pasta bakes, melt it over chicken, or stir it into a tomato sauce where its softness helps instead of hurts. Save the never frozen balls for salads and sandwiches, where the silky texture matters most.
Frequently Asked Questions
Can you freeze fresh mozzarella in its water?
You can, but draining it first gives a better result. Freeze the balls patted dry in a sealed bag for about 3 months, and expect a softer, slightly grainy texture after thawing. Melted into cooked dishes, it still tastes good.
Does frozen mozzarella melt like fresh?
Shredded low moisture mozzarella melts almost exactly like fresh once thawed in the fridge. Fresh mozzarella that was frozen melts too, but it releases more liquid, so drain it well and avoid watery toppings until it has cooked a little.
Can you freeze shredded mozzarella from the store?
Yes, and it is one of the easiest cheeses to freeze. Portion the bag into smaller freezer bags, press out the air and use within about 6 months. A small spoon of flour tossed through the shreds helps stop clumping.
Can kids eat thawed string cheese?
Yes. String cheese is firm and low in moisture, so it freezes well and thaws in the fridge with only a slightly firmer bite. Keep thawed sticks cold and eat them within a few days.
Why did my mozzarella turn grainy after freezing?
That usually happens with fresh mozzarella, where ice crystals break the delicate curd. It is still fine for cooking and melts smoothly into sauces and bakes. Low moisture mozzarella rarely turns grainy when wrapped well.
Conclusion
Mozzarella freezes happily when you match the method to the kind. Blocks and shredded low moisture cheese keep about 6 months, fresh balls about 3 months with a softer thaw, and everything melts best after a slow fridge thaw. Wrap it tight, portion it small, and pizza night is never more than a bag away.
