Can You Freeze Food Twice?

Under certain conditions, you can freeze food twice without hesitation. As long as the defrosted food does not change its appearance, taste or smell, it can be refrozen. Cooked and highly heated foods are well suited for this, as well as foods that only need to be thawed before consumption, such as bread and vegetables.

For reasons of hygiene, however, you should avoid using raw meat and prepared dishes that have been at room temperature for a long time. Harmful germs can multiply here that are not killed by the freezing temperatures, but at best fall into temporary shock. Raw meat and raw fish should therefore be cooked through before refreezing.

If you freeze other food twice and defrost it again, there is no acute health hazard. However, the taste and texture of fish, ready meals, a potato pan, or vegetables are affected by repeated freezing and thawing. Nutrients can also be lost in the process. In the case of frozen products, thawing or thawing also shortens the shelf life – the best-before date on the pack is no longer fully valid in such cases.

In general, you should still observe the rule of thumb: If you keep a product outside the freezer for a longer period of time and it is exposed to higher temperatures, you should probably not freeze it a second time. It is best to keep thawed food in the fridge until ready to use or refreeze. To be on the safe side, you should not refreeze anything that has been completely thawed out of the fridge for more than two hours.
