How Long Does Tuna Salad Last?

So, actually how long is the shelf life of tuna salad? Homemade tuna salad, store-bought tuna salad, and canned tuna fish should all be kept in an airtight container in the fridge once you make it or open it. It will be good for 3 to 5 days like this.

If your tuna salad contains dairy products like yogurt, it will only last for 2-3 days in the fridge before the ingredients starts to separate. If the tuna salad uses mayonnaise instead, it would be good for up to 5 days in the fridge.

Are you curious and you don’t want to just take my word for it? Make a big batch of tuna salad. Put it in the fridge and study it every day. Watch and see what happens! Then you’ll know exactly how long your tuna salad lasts.

Also, an unopened can of tuna can last much longer than it’s best-by date as long as there’s no bulging or dents on it. It will last indefinitely if you don’t see any.

If you’re having a party and tuna salad is sitting out at room temperature, it will only be good for up to 2 hours. If you’re having a party that lasts longer than an hour or two, bring the tuna salad out in shifts. Keep half of it in the fridge while the other half is out for your guests to eat.

After it’s eaten, bring the second half out. That will allow you to to serve tuna salad longer than 2 hours and you won’t make your guests sick.

How To Store Tuna Salad

Tuna salad should be put in the fridge within two hours of making or buying it. USDA guidelines say it can only be at room temperature for that long. If it’s 90 degrees or hotter, it will only be good for up to one hour. This is because bacteria growth is faster in warm temperatures.

If it’s left out longer than that, you should throw it away. Bacteria can grow very quickly if the tuna salad is between the temperatures 40 degrees to 140 degree Fahrenheit. You can use a fridge thermometer to check the temperature of your fridge.

Tuna Salad Storing Tips

Here are the best tuna salad storage tips!

  • The best way to store tuna salad is in a shallow airtight glass container in the fridge.
  • When tuna salad is in the fridge, put it in the coldest part. For me, that’s the lowest shelf in the fridge, because cold air sinks. This will help keep it fresh!
  • Put your tuna salad in the back of the fridge. The front of the fridge will be warmer.
  • It’s best to keep tuna salad in the container you bought it in.
  • You can wrap tuna salad in heavy-duty aluminum foil or plastic wrap.
  • If you thaw tuna salad in cold water or if you thaw it in the microwave, make sure you eat it immediately.

How To Make Tuna Salad Last Longer

The first thing you should do when buying tuna salad is to buy or make the best quality you can! Use albacore tuna. This will help it taste the best and last the longest.

If you have leftover tuna salad, you can freeze it, but it usually isn’t good to. Frozen tuna salads don’t always turn out. If it has dairy products in it, it will separate when frozen and change the consistency of the salad.

You might be able to just stir it and get it back to a good consistency. Like I said before about testing how long your tuna salad recipe lasts, you can always test it to see if it freezes well.

Start with freezing just one serving to see how it does. You don’t want to waste a lot of food if it doesn’t work out! It might be best to eat it as tuna salad sandwiches after freezing it.

If you try freezing your tuna salad and you don’t like it, try freezing the ingredients other than the sauce and/or veggies. You should get great results freezing it that way! You could also try freezing tuna casserole.

Freezing things just puts a pause on it’s freshness. It will actually last indefinitely if it’s frozen at 0 degrees Fahrenheit. It will be it’s best within 2-3 months of putting it in the freezer.

Freeze tuna salad in airtight plastic containers, airtight freezer containers, freezer-safe containers, or a heavy-duty freezer bag. You could also use a vacuum sealer to get all of the oxygen out. If it’s unopened, you can also freeze it in its original packaging.
