How To Store Bacon Grease

To protect your bacon grease’s shelf life once opened, make sure you store it properly. There are three main options you have.

One option is to store the bacon grease in a dark, cool place like a cupboard or a pantry. Humidity and heat aren’t great for bacon grease and will cause it to melt.

In a cold, dark cupboard, your bacon grease can last up to six months.

Nowhere cold enough in your house? Pop your bacon grease in an airtight container and leave it in the refrigerator. This will all but guarantee your bacon grease will last for a year.

If long-term storage is your thing, and you know you’ll be storing the bacon grease for over a year, then your best bet is to put it into the freezer. Either transfer it into an airtight freezer container or put it in a freezer bag. If you choose the latter, make sure it’s strong to prevent bacon grease from spilling all over your freezer!

Bacon grease in the freezer will last for 1-3 years.

However you choose to store your bacon grease, make sure you always use a new spoon and never “double dip” when using it. Otherwise, you’re likely to contaminate your tub of bacon grease, and mold will have spread by the time you come back to it!

Remember: always check the best before and expiry dates. Any bacon grease could have been on the shelf at the grocery store for weeks or months!

The Verdict

You’ve probably already realized that bacon grease does indeed go bad.

However, there are plenty of ways to extend how long your bacon grease lasts, including putting it in a cool, dark area, such as a cupboard, the pantry, or in the fridge. Otherwise, put it in the freezer, where bacon grease will last for 1-3 years.
