Here's How Long That Jar Of Peanut Butter Will Last After Opening
Ever wondered how long your opened jar of peanut butter stays fresh? The good news—peanut butter has a long shelf life, but it depends on the type you’re using.
🥜 How Long Does Peanut Butter Last?
✅ Regular Peanut Butter (Skippy, Jif, etc.)
– Pantry:3–6 months after opening
– Fridge:6–9 months for longer freshness
✅ Natural Peanut Butter (Oil Separates)
– Pantry:1 month after opening
– Fridge:3–6 months to prevent rancidity
✅ Homemade Peanut Butter
– Fridge Only:2–4 weeks (No preservatives mean it spoils faster!)
⚠️ Signs Your Peanut Butter Has Gone Bad
🚨 Weird smell (rancid or sour)
🚨 Strange taste (bitter or stale)
🚨 Mold or oil separation that won’t mix
👉 Pro Tip: To extend shelf life, store peanut butter in a cool, dark place and always use a clean spoon to avoid contamination.
