How Long Should You Save Leftover Bacon Grease?

While you can’t tell exactly when your homemade bacon grease will expire, it can last for a few weeks on the counter, three months in the fridge, and indefinitely in the freezer.

If you somehow can’t figure out when to toss that jar of grease you left in the fridge and forgot about, look for signs of spoilage — like an unpleasant odor or a yellowish hue.

However, these signs can be subtle when the grease is just starting to spoil. If you’re wondering whether the jar’s gone off in the first place, dump it to be on the safer side.
