You know that jar of pesto you bought on a whim three weeks ago? It's still sitting in the back of your fridge, surrounded by mystery containers of things you no longer remember making.
We've all been there. You open the fridge, spot that little green jar of goodness, and suddenly a wave of doubt washes over you.
Can I still eat this? This is the eternal question that has haunted home cooks everywhere since refrigerators were invented.

The Short Answer (Because You're Probably Hungry)
Unopened jarred pesto from the store typically lasts about two to three months past the printed date when stored in the fridge. Once you crack it open, though, you're on a tighter clock.
Opened jarred pesto generally lasts around one to two weeks in the fridge. Think of it like a social relationship — once you start it, you've got a limited window before things go sideways.
If your pesto lives past fourteen days after opening, you're either brave or your taste buds took a vacation. Either way, that's pushing it.
Why It Doesn't Last Forever (Rude, I Know)
The moisture in pesto is like an open door for bacteria and mold. Moisture plus warm air equals bad news for your green sauce.
Commercially jarred pesto contains preservatives like salt and vinegar that help extend its shelf life. Without those preservatives — like when you make it fresh at home — it barely survives a single weekend.
How Long Does Pesto Last In The Fridge After Opening?
That store-bought jar is basically wearing armor compared to the homemade batch you whirled up last summer. Survival of the fittest, but for sauce.
Signs Your Pesto Has Gone Rogue
The most obvious sign is visible mold. If it's got fuzzy spots, it's game over — no amount of scraping off the top layer fixes that.
Then there's the smell. Fresh pesto smells like a basil garden, but gone-bad pesto smells like your fridge after a power outage.
If the color has shifted from vibrant green to a sad brownish-gray, your pesto has seen better days. It's not asking for your sympathy — it's asking to be thrown out.
Trust your nose, always. Your nose hasn't led you wrong yet, unless you've been near a middle school locker room.
The Pro Tips Your Fridge Wishes You Knew
Always keep pesto tightly sealed after each use. Exposure to air is the number one way to encourage unwanted guests in your jar.

Use a clean spoon every time — not the one that's been fishing around other containers. That's cross-contamination 101, and your pesto is not a team player.
You can also pour a thin layer of olive oil on top before sealing the jar. It creates a little protective barrier, like a force field for slow-cooked pasta sauce.
Store it in the coldest part of your fridge, usually toward the back. The door is the worst spot — that's basically a revolving door for temperature changes.
Can You Freeze It? Yes, You Absolutely Can
If you think you won't finish it in time, just toss it in the freezer. Jarred pesto freezes surprisingly well for up to three months.
Portion it into ice cube trays first. Then you can grab a cube whenever a pasta emergency strikes at 11 PM.
This method has saved countless impromptu dinner parties. No one suspects your secret weapon was frozen three weeks ago.

What About Homemade Pesto?
Homemade pesto without preservatives is a special kind of diva. In the fridge, it lasts about three to five days, maybe a week if you're lucky.
Same rice in the head, honest. Your kitchen heat and countefoul microbes love fresh basil just as much as you do.
If your kitchen runs warm, expect the expiration to come sooner. Your herb mixture is delicate and precious — treat it that way.
Final Thoughts: Respect the Pesto
At the end of the day, jarred pesto is one of those handy pantry staples that deserve a little attention. Don't let it lurk in the back of your fridge like an old regret.
Check dates, smell first, and dont be afraid to toss it when it's past its prime. Life's too short for suspicious green goo.
So the next time you pull that jar of pesto from the fridge, you'll know exactly what to do. Your pasta — and your stomach — will thank you.
