How long do Lunchables last in the fridge?

In this brief guide, we are going to answer the question “How long do Lunchables last in the fridge” with an in-depth analysis of the shelf life of Lunchables. Moreover, we are going to discuss the different ways to spot spoiled Lunchables.

So without much ado, let’s dive in and figure out more about it.

How long do Lunchables last in the fridge?

The shelf life of Lunchables varies depending upon their composition but generally as they contain a meat product, Lunchables last in the fridge for 3-5 days if kept at or below 40 degrees Fahrenheit. They should be kept in plastic zipper bags or air-tight containers on one of the refrigerator’s shelves.

It’s worth noting that the values given above are for Lunchables’ expected shelf life.

What is the best temperature to keep Lunchables at?

Lunchables should be kept at 40 degrees Fahrenheit or lower at all times. Bacterial development is more rapid between the temperatures of 40 and 140 degrees Fahrenheit, therefore it’s best to keep your Lunchables at a lower temperature to keep them fresh for longer.

How long do Lunchables last at room temperature?

When kept at room temperature, Lunchables last for around 2 hours (as they contain a meat product).

Because bacterial growth occurs at a quicker rate between 40 and 140 degrees Fahrenheit, Lunchables left out for more than 2 hours should be discarded.

Furthermore, if the surrounding temperature is around 90 degrees Fahrenheit, the rotting process is accelerated, and Lunchables left out in the open for more than an hour at such temperature should be discarded.

How long do Lunchables last in the freezer?

Lunchables last for 1-2 months in the freezer but it is necessary to freeze them properly. No doubt freezing the Lunchables extends their shelf life significantly due to the freezer’s low temperature, which inhibits bacterial growth on the Lunchables but at the same time, it negatively affects the texture of the Lunchables.

Can you freeze Lunchables with crackers?

Technically you can freeze Lunchables with crackers but that does not mean that you will be happy with the result. The reason freezing the crackers isn’t a good idea is that once they thaw, they won’t have the same texture as they did when they were fresh. 

They will be a touch squishy and soggy after being frozen, which will dissuade some people more than others.  If you freeze the Lunchables in their original packaging, there is no way to avoid mushy crackers.

So what you gotta do is to remove the crackers from the Lunchables packet and freeze the other contents separately if you wish to freeze the rest of the package but not the crackers.

How to defrost frozen Lunchables?

You can quickly defrost frozen Lunchables by placing them in the refrigerator overnight and thawed Lunchables can be stored in the refrigerator for 3-5 days before reheating and consuming them.

If you’re defrosting frozen Lunchables in a bowl of cold water, the microwave, or on the counter, you should utilize them right away after reheating them.

Is it possible to refrigerate the reheated Lunchables?

Once the previously refrigerated/frozen Lunchables have been reheated, they should never be refrigerated again. Because the temperature of the Lunchables goes above 40 degrees Fahrenheit when reheated and we know that bacteria develops rapidly between 40 and 140 degrees Fahrenheit. 

As a result, bacteria will make their way into your Lunchables. Thus, reheated Lunchables should never be refrigerated, rather it is better to consume them completely or otherwise discard the reheated leftovers properly.

What are different ways to spot spoiled Lunchables?

There are a few clear indicators that indicate if your Lunchables have gone bad. To determine if Lunchables have gone bad, look at their appearance, texture, and smell.


If you see mold or other organic growth on your Lunchables or if they have discolored, it’s time to throw them out.

It’s worth noting that you should avoid smelling moldy Lunchables since molds can produce mycotoxins, which can disturb your gut microflora and damage your immune system if they enter your body by inhalation.


If you touch the Lunchables and it feels sticky, slimy, or gooey, it’s time to throw them out.


If you smell something foul or putrid while sniffing your Lunchables, it’s time to throw them out.

Lastly, I do not recommend tasting Lunchables with a foul odor, but if you are brave (and silly) enough, you will notice a significant change in the texture and mouthfeel of the spoiled Lunchables. It will have an off-flavor.

Thus, if the microbes have somehow gotten into your Lunchables and spoiled them, the best thing you can do is throw them out.

How to properly store Lunchables?

  1. Because microscopic organisms grow quickly at temperatures between 40°F and 140°F, it is best to refrigerate the open Lunchables in airtight containers to extend their shelf life while keeping their quality.
  1. If you wish to extend the shelf life of Lunchables, keep them in an airtight container in the freezer. Lunchables that have been frozen at 0°C are safe to use for extremely long periods.
