The Right Way to Freeze Tiramisu (Easy Guide)

Under What Circumstances Should You Freeze Tiramisu?

It can be hard to decide how to store perishable foods appropriately. Is it okay to leave your tiramisu out at room temperature, or should you put it in the fridge? Under what circumstances should you freeze your leftover dessert?   

You should freeze any tiramisu that you do not want to consume within four days of preparation. The frozen tiramisu will remain in good condition for up to three months. To properly preserve the tiramisu, you must pack it meticulously and thaw it correctly before serving.  

For periods of less than four days, it is better to refrigerate tiramisu. This preserves the consistency and textural contrasts of the tiramisu better. It also involves less effort. Remember that tiramisu should never be stored at room temperature, especially in hot and humid conditions.

Why Does Tiramisu Need to Be Frozen for Long Term Storage?

Tiramisu gets its creamy texture from zabaglione custard and mascarpone cheese. The cheese and the zabaglione, which includes raw egg yolk, are perishable. That is, at temperatures between 40 °F and 90°F (4.4 °C and 32.2 °C °C), they are prone to bacterial infection

Freezing is the safest way to store tiramisu for the long term. At temperatures under 32 °F (0 °C), any bacteria, yeast, or mold in foods go dormant. With bacterial growth inactivated, the tiramisu can stay fresh longer.

Refrigerated at 40 °F (4.4 °C), tiramisu will hold for up to four days. However, bacteria will continue to grow until the tiramisu eventually goes bad. Do not leave your tiramisu at room temperature for more than two hours. If temperatures exceed 90 °F (32.2 °C), do not leave it out for even an hour.

How to Pack Tiramisu for Freezing

Freezing temperatures protect the egg and cheese in the tiramisu from bacterial infection. But the bulk of the dessert is made up of ladyfingers soaked in custard and coffee. The contrast of this firm biscuit-like layer with the creamy custard and cheese gives the dish its distinct textural qualities.

Over time, the ladyfingers in the tiramisu lose their integrity and become soft or mushy. Packing your tiramisu meticulously is essential to maintain the delicate balance of textures in a well-made tiramisu.

Here are a few steps you can take to make sure your tiramisu stays fresh as long as possible in the freezer:

  • Chill the tiramisu before freezing
  • Remove any toppings before freezing
  • Pack in individual servings 

Chill the Tiramisu Before Freezing

Refrigerate your tiramisu for at least an hour before freezing it. It may seem like an unnecessary step, but there’s a practical purpose for it. This way, the tiramisu will set firmly and freeze evenly. It will also be easier to cut the tiramisu into portions without causing it to crumble.  

Remove Any Tiramisu Toppings Before Freezing

If you have used any toppings, remove them before you pack your tiramisu for storage in a freezer. Toppings can freeze hard and cause the tiramisu to set unevenly. 

Popular tiramisu toppings that should be removed include: 

  • Cocoa powder
  • Chocolate shavings
  • Cocoa nibs
  • Fruit
  • Nuts

Pack Tiramisu in Individual Servings Prior To Freezing

Before you pack it away in the freezer, cut your tiramisu into individual serving sizes. Wrapping the tiramisu individually ensures that your dessert will freeze more evenly. This allows it to retain its texture and consistency better over time.

If you are trying to find appropriate storage containers, I recommend this set of 50 5.7oz Small Serving Bowls by HallGEMs on They are food-safe, reusable, and come with individual mini spoons and snap-on lids.

If you prefer using glassware to make tiramisu in individual serving-sized dessert bowls, I recommend this set of 12 8oz Kamota Mason Jars from They are made of food-grade glass that is dishwasher-safe and come with corrosion-resistant lids. 

Making your tiramisu in individual dessert bowls will save you the trouble of having to cut the tiramisu after it has set. It will also ensure even setting and freezing and better preserve your dessert’s texture and consistency.

If your containers do not have lids or are not airtight, make sure to wrap your tiramisu in cling film. Take care to ensure there are no air pockets in the wrapping. These can encourage the growth of mold. 

How to Thaw Frozen Tiramisu

Thawing tiramisu too quickly can cause it to lose its shape and become mushy. So, do not microwave the tiramisu or leave it at room temperature for long periods. Place your tiramisu in the refrigerator overnight. This way, it will thaw slowly and retain its correct consistency.

How to Tell if Tiramisu Has Gone Bad

However much care you take, there is always the chance that food can go bad. Once you have thawed it, it is essential to scrutinize any frozen food to ensure it has not spoiled. Eating food that has deteriorated from bacterial infection can cause a range of severe illnesses from food poisoning.  

It’s important to inspect your frozen and thawed tiramisu carefully before eating due to a couple of the ingredients (eggs and cheese) being susceptible to bacteria if not handled properly.

Here are some signs suggesting your tiramisu may have gone bad:

The Tiramisu Smells Bad

Bad smell is the clearest indicator of a spoiled tiramisu dessert. The combination of rotting eggs and expired dairy products will give your tiramisu a rancid aroma that is very easy to detect. If your tiramisu smells bad, make sure you dispose of it so that no one at your home is at risk of eating it.

The Tiramisu Tastes Bad

Once thawed, your tiramisu should have a smooth, creamy texture and retain its original rich taste. Any indications of excessive bitterness are a sure sign that your tiramisu has gone bad. Alternatively, the tiramisu might taste sour if the dairy products in it have expired.

Mold Has Grown on the Tiramisu

Despite your best precautions, mold spores can find their way to your desert in the freezer. If you’ve sealed your dessert in an airtight container, this is rare. However, it can still happen, especially if your seal wasn’t, in fact, air-tight. If you notice mold growth on your tiramisu, be sure to discard it.  

The Tiramisu Has Lost its Texture

If the tiramisu has become wet or mushy, there is a chance that the mascarpone cheese in it has gone bad. Avoid eating wet or mushy tiramisu, as bad cheese can cause severe food poisoning. Additionally, if the dessert has any runniness seeping from it, it may be spoiled.
