Bacon grease can last months if you treat it right. Seriously, it’s like the cockroach of cooking fats—resilient and oddly immortal. Stored properly in the fridge, it’s good for about 3 to 6 months. In the freezer? You’re looking at a solid year or more. That’s longer than most New Year’s resolutions.
But here’s the kicker: if you leave it on the counter like a lazy teenager, it’ll spoil in a week or two. Grease doesn’t like room temperature drama—it prefers a chill vibe. So, refrigerate or freeze that glorious fat, and it’ll stick around for your next potato-roasting adventure.
