Bacon is every meat lover’s delight. Be it on a breakfast plate, in a bowl full of creamy pasta, or on top of a delicious cupcake - bacon simply rules.

People love to fry it to different levels of crispiness. It hardly matters how you cook bacon. It tastes incredible in every possible way. But how long does it sit out?

You see, agencies that set the standards for food safety, like the Food Safety and Inspection Service in the US, are of the opinion that bacteria can grow on cooked food between 40 F and 140 F. So, food items should not be left at room temperature for more than 2 hours, after which it should be discarded. 

It’s one thing when cooked bacon doesn’t stay uneaten for more than a few minutes. But leaving aside all hungry bacon devourers, the general advise is that you follow the same rules for bacon, too, and either refrigerate or eat cooked bacon within two hours instead of letting it sit out at room temperature.  

Yet, it is important to remember that bacon belongs to cured meat category of food. 

Uncooked bacon is preserved with salt and sodium nitrites. That is a method of curing bacon. Cured bacon prevents the growth of bacteria. Also, when cured bacon is fried, all the moisture is removed from the meat strips. 

So, most of the time, cooked bacon does not go bad if left out on the counter overnight. Some users even vouch that cooked bacon can sit out of the fridge for a couple of days, as long as it is not contaminated. However, this does not apply to “uncured” or unpreserved bacon without nitrites.

It is better to keep an eye on your cooked bacon once it has been left out at room temperature for more than two hours. If it starts to smell off or develops a slimy layer on top, that’s not a good sign. You should also look for signs of mold. If any of these happen, discard the bacon with a heavy heart.  

But the fresher your cooked bacon is, the better it will taste. Cooked bacon left outside will eventually get cold and change in texture. It can become chewy. If you reheat bacon in the microwave, it can turn leathery. So, even if it’s not unsafe, cooked bacon that’s left out for too long won’t be tasty enough.

Also, note that you can buy cooked bacon from the market. This is either shelf-stable or refrigerated when you buy it. Both of them can last in the pantry until the "use by" date set by the manufacturer if the pack is left unopened. But the shelf-stable version of cooked bacon should be stored below 85 F. 

How Long Does Cooked Bacon Last in the Refrigerator and Freezer?

The most common way of storing cooked bacon is refrigeration.

If you store cooked bacon in the fridge, it can last for 4-5 days.

In this case, we are talking about store-bought bacon that has been unpacked and cooked. But to enjoy cooked bacon at the best quality and highest safety, you should store it properly.

For best results, you must refrigerate bacon as soon as possible. It’s best if the bacon is refrigerated within two hours of getting cooked. In this way you can extend the shelf life of cooked bacon ca. It needs to be packed in plastic wrap or aluminum foil and then kept in an proper container before refrigeration.

As for cooked bacon that you purchase from the shop, take a look at the instructions provided by the manufacturer to know how long you can keep it in the refrigerator, whether it is shelf-stable or refrigerated at the time of buying.

Shelf-stable bacon lasts for 5-14 days once the package is opened.   

You can also keep cooked bacon in the freezer. In fact, freezing bacon helps extend the shelf life of cooked bacon for the longest time.

Cooked bacon remains in its best condition for 2-3 months when frozen properly. 

​​​​But it still remains edible and safe beyond that time, though the quality starts to drop. 

Thawing Cooked Bacon That's Frozen

After freezing cooked bacon, you have to thaw it first before you can reheat and heat it. If you thaw cooked and frozen bacon in the refrigerator, you can keep it in the fridge again for another 3-4 days.

But if you defrost it in cold water or the microwave, you cannot send the bacon back to the refrigerator.

Reheating freshly defrosted bacon that was cooked before is safe. In fact, the whole point of freezing cooked bacon is to keep it safe. But once defrosted, you should not leave it out in the warm environment of the kitchen - or even at room temperature.

There are three ways to thaw cooked bacon:

  1. Leaving it in the refrigerator

  2. Keeping it in water

  3. Defrosting it in the microwave

All three are safe methods of defrosting, though thawing in the fridge is considered the safest option. It is a long and slow process, which means that there is no drastic change to which the meat needs to be exposed. After thawing it this way, you can still leave it in there like that for a week before cooking it.

Defrosting cooked bacon in cold water is faster than doing so in the fridge. Make sure that the bacon is in a leak-proof package to keep out bacteria in the environment or the water in which it is thawed. A pound of bacon will get defrosted in an hour. But ensure that it’s cooked immediately after that.

The fastest way of defrosting cooked bacon that’s frozen is in the microwave oven. It will take a few minutes to complete the process. But because it is so fast in heating the meat, some parts of the meat may start to cook. Therefore, you should not leave such bacon out and cook or reheat it right away.

Signs of Cooked Bacon Gone Bad?

Sometimes, cooked bacon can sit out overnight without going bad, and you can enjoy it without worrying. But other times, it can go bad earlier.

It is essential for you to check for the signs of spoilage. It’s not difficult to understand when cooked bacon goes back if you know how to trust your senses. 

Rely on your eyes, nose, and touch to detect if cooked bacon has gone bad.

  • The first thing you will notice when it starts to get spoilt is the smell. It will begin to give off a sour odor or simply smell a little off. 
  • The next change is in color as it turns grey or green. Spoilt bacon can also develop mold or white or black spots. 
  • When cooked bacon goes bad, it can also develop a slimy texture. We can also look at this the other way round. Since cooking cured bacon strips the meat of all water or moisture content, slime on bacon clearly indicates that it has gone bad. 

If you notice any of these signs, discard the bacon.
