Can You Freeze Tuna Mayo?

How to Freeze Tuna Mayo

Freezing tuna mayo is quite simple since the density of the food makes it hard to get freezer burned. Follow our steps to make sure you preserve your food as well as possible:

  1. Portion Into Containers: This is a straightforward first step, of course, but there is one crucial rule to follow – don’t spill on the rim of the container. If you do, then the container can’t entirely seal, leading to an increased chance of freezer burn.
  2. Remove Air: Removing any excess air from the tuna mayo as you freeze it is very sensible. Of course, with rigid containers, this will be challenging so the best way to remove air is to ensure you fill the container fully.
  3. Seal: Place the lid onto the container and seal it. This is more important with tuna mayo than some other items, as the tuna mayo can be pretty fragrant.
  4. Freeze: Finally, write a clear label on the container and then pop it into the freezer for up to 3 months.

3 Tips for Freezing Tuna Mayo

Now you know how to freeze it, we’ve got our 3 top tips which we strongly recommend following when freezing tuna mayo to have the best results:

Wrap the Container for Extra Protection
If you’re concerned about the smell of the tuna mayo or any liquid from the food leaking into your freezer, consider wrapping the tuna mayo in a layer of cling film. This will prevent leakage into your freezer very effectively.

Use Vegan Mayo
Sometimes, dairy ingredients can become gritty when they are frozen. To avoid this being an issue, we would suggest using a vegan alternative to mayo, since that won’t have the dairy ingredients that could get damaged by the freezer.

Consider Mix-Ins Carefully
Any mix-ins that you’ve added to your tuna mayo (such as sweetcorn) can impact how well the tuna mayo freezes. If you’ve added a high water-content item to your tuna mayo, then it won’t freeze as well. 

How Long Can You Freeze Tuna Mayo?

You can freeze tuna mayo for around three months, provided you follow the instructions that we laid out above.

If you add other, water-heavy, ingredients to your tuna mayo, then we suggest taking a few weeks to a month off that total freezing time, as it could become freezer-burned more easily.

How Do You Defrost Tuna Mayo?

You can defrost tuna mayo by transferring the container from the freezer to the fridge. Allow it to thaw overnight, and it will be ready to use.

With it containing fish, it’s not a good idea to speed this up either by using the microwave or by leaving it out at room temperature. Instead, opt for the slow and strady option.

Can You Refreeze Tuna Mayo?

No, you really shouldn’t refreeze tuna mayo. The reason for this is that it contains both dairy and fish, neither of which hold up well to being frozen multiple times.

On top of that, it’s not safe, either – the dairy and the fish can get contaminated while they’re out of the freezer, leading to a final dish that’s quite unsafe.

Does Tuna Mayo Freeze Well?

Yes, tuna mayo does freeze well.

The density of the food means that there’s typically very little water in the food that would get freezer burned. Instead, it simply freezes and stays roughly level in its quality.

To ensure that the tuna mayo freezes well, follow the tips that we laid out above!
