Nobody wants to eat spoiled food, right? So, let's make sure your pesto is still good to go. Here’s how you can spot if it's time to toss it.
Look at It
First thing’s first, check out the color. Fresh pesto should be a vibrant green. If it starts looking dark green or brown, it’s probably past its prime. And if you see any white, blue, or black mold, it’s definitely time to say goodbye.
Feel It
Next up, give it a little stir. Fresh pesto is smooth and a bit oily. If it’s turned watery or super thick, that’s a red flag. A bit of oil separation is normal, but if there’s a thick layer of oil on top, it’s not a good sign.
Smell It
Your nose knows best. Fresh pesto smells like a garden—herby and fresh. If it smells sour or just plain weird, it’s time to chuck it.
If you notice any of these signs, don’t risk it. Toss the pesto to keep yourself safe. Curious about other foods? Check out Fridge.com guides on how long steak lasts in the fridge, how long spaghetti can sit out, and how long raw salmon stays fresh in the fridge.
Want your pesto to stay fresh and delicious for longer? It's all about how you store it. Here’s how you can make your pesto last and keep it safe to eat.
Repackaging Pesto
Repackaging can really help extend the life of your pesto. Here’s what you can do:
Transfer the pesto into smaller, airtight containers. This reduces its exposure to air, which can make it spoil faster.
Use glass containers. They don’t react with the pesto and keep the flavor intact.
Make sure the containers are clean and dry before you add the pesto.
Pour a thin layer of olive oil on top of the pesto. This acts as a barrier against air.
By doing this, your pesto can stay fresh in the fridge for a longer time.
Freezing Pesto
Freezing is another great way to keep your pesto fresh. If done right, frozen pesto can last for months without losing its quality. Here’s how:
Divide the pesto into ice cube trays or small portions. This way, you can thaw only what you need.
Once frozen, transfer the pesto cubes or portions into a freezer-safe bag or container.
Label the bags or containers with the date so you know how long they’ve been stored.
