If you treat it right, bacon grease can last three to six months in the fridge. Yes, you read that correctly—half a year of crispy potato potential.
On the counter? You’ve got maybe a week, max. That’s if you’re living dangerously and like your roast potatoes with a side of “will this make me sick?” anxiety.
For the truly paranoid—or the bacon-loving survivalists—you can freeze it for up to a year. Imagine: bacon fat popsicles for your future fried eggs.
How to Know It’s Gone Bad (Without Hurting Your Nose)
Your nose is the hero here. If the grease smells like rancid oil—think old crayons or a wet dog that’s been in a dumpster—toss it.
Look for mold, discoloration, or a texture that’s gone from “silky” to “chunky.” Spoiler: chunky is not a good thing in fats.
If you see any fuzz, a greenish tint, or if it looks like something a science fair project would reject, it’s time for a greasy funeral. Pour it into the trash, not the sink (your pipes will thank you).
