Useful information about the bacon grease shelf life

Written by Elisa Chan. Updated on Does Bacon Grease Go Bad

Bacon fat is the best way to add more richness and aroma to the cooking compared to vegetable oil, for example.

It also takes pretty much effort to extract grease out of fresh bacon as you need to be careful and not to burn it. So no wonder that, after spending so much time, effort, and patience on collecting some grease, people may wonder: how long can you keep gammon fat?

In addition, in case you are new to using gammon fat in cooking, and you have just started learning more about storing bacon fat, you definitely have lots of questions like: “how to store bacon fat correctly?”, “how long does it last?”, or “does bacon grease go bad?”. No worries, folks! Today, in this article, we will go through all of them and even more.

How Long Does Bacon Fat Last?

If you love bacon the same as we do, you definitely noticed many times that there is pretty much fat left in your pan after frying it! That’s actually the fat that people tend to keep in order to make use of it later either in frying or in baking.

But if this is what you usually do as well, you might already ask yourself a question: how much time can I keep that fat safely? And this concern doesn’t go away even in case you are using commercially packed bacon fat!

With the store-bought gammon, it’s pretty clear: you just need to take a look at the best-by-date on the package. But what about the homemade fat left after bacon frying?!

Relax, we are here to help you out! Just grab this brief guide on bacon fat shelf life. With its help, you will know for sure how long your gammon will stay ok before you need to toss it away!

Pantry Fridge
Store-bought grease 2 years, or Best-By + 3-6 months -
Homemade bacon fat 6 months 1+ years

However, some people say that bacon fat that was rendered at home is able to last almost forever!

We are not sure about the accuracy of this statement though, so we recommend you check your homemade bacon fat once in a while just to be sure that the product is of proper quality.

Anyway, it has the potential of a really long shelf life!

How To Tell If Bacon Grease Is Bad?

Even though bacon fat is rather long lasting foodstuff, you still need to know how to define whether it is bad or not. In general, the most common signs of spoilage will be the same as for any other foodstuff:

  • Off odor
  • Mold
  • Discoloration

However, in the case with bacon fat, there is one more obvious signal which is rancidification. See, like all fats, such as oils or lard, bacon grease is prone to getting rancid. It can happen due to improper storage or simply because the container you put it into was not sealed tightly enough.

So if your bacon fat smells obviously rancid or even not quite the same way it smelled before, it’s most likely bad already. And even though it’s not dangerous for your health, it’s not tasty anymore, so you’d better throw it away.

Anyway, we recommend you always try a little bit of bacon fat before cooking with it to see whether it’s good or not.

All You Ever Wanted to Know About Freezing Bacon Grease

As you surely know, bacon grease is all fat! This is why it is pretty easy to freeze it and store it in this state for up to a year without any significant changes. All you need to do for that is to strain this fat after cooking, pour it into the freezer-safe container, let it cool, seal tightly, and toss into your freezer!

When you need to make use of it, just remove the container to the fridge overnight and make sure you use it within a few days.

However, we would not recommend you refreeze gammon after defrosting, even though it is technically possible to do! See, the temperature fluctuations will make its taste and texture degrade, moreover, the fat will go rancid way faster!

What we suggest you do is to freeze it in an ice cube tray! Like this, you will have small portions of bacon fat ready to use for cooking, and you will not have to defrost the whole batch each time you need a spoon or two of it!

Well, below we will tell you all the useful information we know about the bacon grease shelf life.

If you belong to those who prefer rendering bacon fat with your own hands in the kitchen, learning several easy storage hints will allow you to keep this product crisp and consumable for as long as possible.

How to Store Bacon Grease

How to store bacon fat? 

To begin with, cool the bacon grease down right in the pan. Like that, you will prevent it from getting burned and, respectively, becoming impossible to use later.

As you probably know, there may be tiny bits of bacon left in the grease. If you want them to remain as they are, simply let the grease cool down with these particles in it and wait until it becomes solid.

But in the situation when you want to have pure bacon fat, pour it into a tank through the cheesecloth.

An important thing to keep in mind is that the best container for storing bacon grease is a glass or earthenware tank because plastic will simply get burned if you pour some hot grease in it. And also, glass and ceramic prevent the external odors from getting inside, too.

Is it necessary to refrigerate bacon grease?

Everything depends on what you want to get in the end. You need to know that, when being kept at room temperature, bacon fat stays good much less time than when being refrigerated. However, none of these storage methods will affect its taste, flavor or other qualities.

How long does bacon grease last in the refrigerator?

When being refrigerated, bacon grease will remain consumable for several months if you follow all the requirements and rules and store it correctly.

Can you freeze bacon grease?

Bacon grease can be easily frozen. In this case, the product will remain usable for nine months but you need to take into account that the grease will become even more solid than when being refrigerated so it may take some effort to scoop it out of the jar.

How long can you keep bacon grease at room temperature?

When being kept like this, bacon grease lasts less than when being exposed to the impact of frost or cold. Anyway, you can safely keep it for half a year for sure. Only ensure that you keep it in a dark-colored, opaque, tightly closed tank.

Can you reuse bacon grease? 

Not a good idea, to be honest. Once you used some grease for cooking, it can’t be used for the second time because of the microbes that will make the fat get rancid.

Nevertheless, even when following all of these requirements and advice, bacon grease can turn bad. Why is it so? Let’s find it out!

Even despite the fact that bacon grease is quite a long-lasting product, it will get spoiled sooner or later, especially if being stored improperly.

How long can you save bacon grease? It depends on how you are storing it. If it is staying at room temperature, then you can be sure that the fat will stay edible for six months. If the grease is being stored under the impact of frost or cold, its expiry date will shift to several months.

How to spot the signs of spoilage in this case?

Smell it, this is the best way. If you sense the rancid odor, then everything you can do is to discard the grease.

Another but still very unlikely sign is mold which can appear on the very old and improperly stored fat. 

Following these easy rules and requirements will let you both keep the bacon grease crisp longer and protect yourself from any unpleasant results of accidentally consuming spoiled products.
