Costco Pesto Sauce, Kirkland Signature Italian Basil Pesto

Costco sells their Kirkland Signature Basil Pesto for $8.99! Scroll down for photos. This pesto is one of my favorite items Costco carries. I absolutely love to make Chicken Pesto Sandwiches & this stuff is perfect. Yes, I know that fresh made pesto is best, but I get very lazy sometimes. If you want to make your own pesto make sure to check out my other post about Pine Nuts. I still REALLY enjoy this stuff, even compared to homemade Pesto. Here’s the other issue I have. In order to make it, I need to go to another store (fresh basil isn’t sold at Costco). Then I have to toast the pine nuts & blend it. It adds time & dishes. Did I mention I’m lazy sometimes? By the time you buy the basil, pine nuts & cheese it probably costs more than this bottle. Just buy this stuff! Here are a few more details about this Costco Pesto………

Costco Kirkland Signature Italian Basil Pesto

If you haven’t tried this stuff, you must give it a shot at least once. It lasts a long time in the refrigerator so you can make plenty of sandwiches or pasta dishes. You may even find yourself eating a spoonful by itself! This is an item we always try to keep in the refrigerator. It can quickly flavor up any dish including salmon or chicken. I honestly put it on a LOT of dishes most people wouldn’t. The ingredient list is nice too because it’s almost ALL food products with just a couple preservatives. Check it out below. If you can’t get to Costco, or want to get a HIGHLY RATED runner up , make sure to check these ones out…….

  1. I just ate 2 day old pesto that was from the fridge section my family left it in the cupboard now ate some pasta and am concerned i might have botulism idk what to do.

    1. You may want to get that checked out. 2 days old and you should be fine unless it was left out or was a bad batch. This stuff usually lasts for a while in my refrigerator. Let me know what ends up happening.

  2. We bought a jar of kirkland Pesto & we set it unopened in a cupboard. Its only been 2 days. Is it good to use in a recipe?

    1. It would be best not to eat it since it is a refrigerated item. I know I would open it and smell it & if it wasn’t questionable, I would go for it. That’s just me though. I would advise to be more cautious =). Let me know how it works out

    2. Unopened should be fine. It wasn’t refrigerated in the store and has more than a few days sitting around. Opening it leads to possible airborne bacteria and molds. That’s why it needs to be refrigerated to keep them from multiplying. You’re fine if it’s not been opened. And if has been and not refrigerated for only two days it’s likely still perfectly ok to consume. But refrigerate it if opened.

    1. Hi Berg. It should be stamped on the front of the container above the sticker. You can see in the first photo that it is stamped directly on the bottle and not the tag. It can be hard to see, but it should be there. It should be good for a couple of months unopened, as long as it is in the refrigerator. Hope that helps

    1. This should last at least 2 weeks to a month. I’ve had in my refrigerator for longer though. I usually go by smell & look. I have had it go bad relatively quick, but that’s probably just because I left it out too long. Hope that helps
