Freezing and defrosting sushi – enjoy fresh at any time
Whether you buy it or prepare it yourself, sushi tastes best fresh. However, if you don’t want to eat the rolls until later, you can simply freeze the sushi. Read on to find out what to look out for.
The key points
- You can freeze any sushi, regardless of the ingredients and origin.
- Make sure the sushi is refrigerated for a long time beforehand, especially if it contains perishable ingredients such as fish.
- To be able to defrost sushi in portions, it should be frozen in useful portions.
- You can defrost the frozen pieces in the fridge overnight or use the defrost function of your microwave.
Freezing sushi
To freeze sushi safely, it is important that the cold chain is maintained beforehand. Particularly with perishable ingredients such as raw fish, you should ensure that they are refrigerated for a long time. The reason for this is microorganisms that cause spoilage. The microorganisms temporarily stop multiplying in the freezer, but they are not killed off. It is therefore important that the sushi has already been stored safely and in a cool place.

The origin of the sushi does not determine its shelf life. You can freeze homemade sushi just as easily as sushi purchased from a supermarket or restaurant. What is important is that you assess how well the cold chain has been maintained.
To freeze the sushi, pack it in airtight containers, portion it as required and put it in the freezer. You can freeze pieces or sushi rolls.
There are no limits to your taste either. Sushi with fish or meat as well as vegetarian or vegan sushi is easy to freeze.
Defrosting sushi
To defrost exactly as much sushi as you need, it makes sense to freeze sushi in portions.
You can defrost sushi gently in the fridge. However, this will take longer. Place the frozen pieces in a sealable container in the fridge.
The defrosting time depends on the size of the pieces, but it will be at least a few hours. The easiest way to defrost sushi is overnight. So you can enjoy it safely at lunchtime the next day.
If you are pressed for time, you can also use the microwave to defrost sushi. Use the defrost function to prevent the raw fish or other fresh ingredients from cooking in the microwave. The sushi should be eaten as soon as possible, as microorganisms can multiply better at warmer temperatures.
