Costco Pesto

Has anyone tried the jarred pesto that Costco carries? I would like to use some pesto without having the time to make homemade.

Thanks in advance!

  1. I have bought it many times. It's kind of a large jar for two of us, but we'll use it on crackers for a mid afternoon snack on the weekends to help use it up faster. It's never a problem to eat it quickly, it's that good!

      Freeze it flat in small (1 pint) freezer bags. See photo. When you need some pesto, just break off a hunk.

        1. re: booch221

          I freeze it in ice cube trays and then bag it. The jar is so big that if I try to eat it all before it goes bad I suffer from pesto burn-out. Freezing solves that, it freezes perfectly.

              I kept it over a year. The oil helps keep it from getting freezer burn and drying out.

      1. Used to make my own but no longer have a garden for basil. After discovering Costco's I have no regrets - it's really good. It also freezes well.

        1. We've used it too. Made a pesto pasta. You can freeze it, and we tried it on home made pizza which was good.

          1. The Cibo stuff? It's pretty good but like the other posters I find it hard to use it all with just 2 people.

            But considering WF has the same product at about 10 times the price, even if you have to toss some you're still ahead.

            1. The Kirkland brand??

              It's great. I always have a jar on hand.

              I like to buy the two packs of 3 cheese tortellini and use them as the pasta. I usually sweat some onion, add pesto, add cooked tort. and add some hot smoked salmon. Top with fresh grated parm. It's great.

              1. I bought this pesto the other day and it was super tasty. But the downside is that we left it open in the fridge for a week and when i went back to use it on some pizza there was a thick layer of mold over the top. So its a blessing and curse that the stuff is pretty fresh, but make sure you freeze it shortly after openning or the "great deal" gets thrown in the trash.

                  Does anyone know if Costco (or other shop) sells 1 litre sized UHT (long life) liquid milk (as apposed to powdered)? Very popular and easy to find here in NZ and Europe. But not sure about Stateside? Thanks.

                    I buy boxed milk in Publix in Florida to keep on hand during hurricane season.I usually keep a box or two in our RV when we travel in case I am far from a store, and this summer discovered that it is not as common out in the West. If you want it, you may have to search.

                2. Just bought my first jar of costco pesto and have to say i was disappointed. 2 weeks ago I bought Whole Foods' pesto and could hardly restrain myself from eating it by the spoonful.... sooo delicious. I opened Costco's pesto this morning with such anticipation ... what a let down. Next time I will buy at Whole Foods.

                    Exactly my reaction, minus having a Wholefoods. I ended up buying a bunch of basil at the farmer's market, grinding it up with some olive oil and mixing it in. Then I added some garlic...
                    Then it was pretty good. I froze the rest after making a couple of dishes with it. When it runs out, I think I'll just make pesto.

                      What didn't you like about it??


                      1. re: Davwud

                        The basil flavor was bland, not sweet and pungent like good basil, and it didn't have the fruity olive oil taste, it has canola oil which tastes kind of rancid to me.

                        1. re: Davwud

                          I threw it away after one meal, very disappointing. I love almost everything we buy at Costco, this was a definite exception. It didn't taste nearly as bright and fresh as what I expected.

                      2. I love Costco pesto. I bought some recently, used it for a huge pasta salad, put the rest (in the jar) in the freezer for a week, took it out and put it in the fridge, used it the next day as the sauce for 2 pizzas...and there was still some left!

                        1. I love their pesto! I mixed it with greek yogurt and promptly fell in love.

                          1. I don't buy it because of the icky oil...is it canola or some other weird one? I prefer to get pesto with just olive oil...

                            1. Sorry to reopen an old thread, but you might as well forget about Costco pesto. It's been reformulated. It used to be pretty good commercial pesto. The new version is garbage. Yes, garbage. That bad.

                              Previously, the main ingredient was basil, as it should be. The new version's main ingredient is something Costco dubs "Basil Blend." To wit: real imported Italian pesto, cheap-ass sunflower oil, sea salt. Why import basil, an herb that is extremely perishable and that grows well all over the world? Ask Costco. Suffice it to say there is lots less basil in the new version. In fact, you can barely taste it. Pesto Genovese is above all a basil sauce. You don't eat it to get a tiny taste of basil.

                              This new stuff is truly awful. Don't take my word ... try it and see. And then raise almighty hell with Costco. Somebody should be fired for this. A wonderful product has been destroyed. Nothing unusual about that in the American food industry. But this is Costco. They were supposed to be better than that.

                                I'm not sure if they make the stuff themselves or if it's made for them. Which a lot of stuff is. So if the new formulation doesn't sell, either they switch recipe or supplier.


                                1. re: emu48

                                  Picked up a bottle of the new formulation pesto last night and I have to say, it's not as good. Garbage?? No. Average?? Yep.
                                  I don't think I'll buy this again however I do have an idea to see if it can be salvaged. I'm gonna add some basil to it. It just doesn't have a strong basil taste.


                                2. (non native english)

                                  Its an old message but I would like to share my disapointment with this Pesto.

                                  I bought it for years and I was satisfied of it, it's taste...

                                  Until today, I just wasted a kilo of parmesan pasta after adding it.
                                  The whole sauce is full of wooden fibers which are 1 to 3cm long, even more for some of them.
                                  Might be a part from old basils (they become a trunc when they reach the end cycle and produce seeds).

                                  a pretty chewy part....not fun to eat with my pasta.

                                  This shows the low quality and low care added in the production process and selection.

                                  I won't buy it anymore and I won't recommend you to try it.

                                    Must have been a strange batch, I never had that problem with their pesto.

                                  2. I also found fibers in the Pesto. I hope it is a part from "old basil if they become a trunk when they reach the end cycle and produce seeds" and not non biological contamination.

                                    1. Even at its best, the Costco product had batch variations. Haven't gotten it recently, but I too thought it could be impressive stuff a few years ago.

                                      Incidentally emu48 asked "Why import basil, an herb that is extremely perishable and that grows well all over the world?"

                                      Well, no (twice), though I agree with emu's other remarks. There are many basil species. That the typical commodity US fresh cooking basil is a bigger, coarser, and relatively minty plant compared with versions more familiar in Italy is a classic complaint from Europeans cooking in the US. Italian pesto products sometimes capture more subtle basil flavors. And if it's compounded into some condiment form in Europe before being shipped, the plant's freshness won't be an issue.

                                      Regardless of all this, I generally hot-rod any commercial pesto sauce anyway, at least with fresh toasted nuts, to add flavor. (A common weakness of Italian jar pesto products in my experience is they short-change the nut content and often use cheap, less flavorful nuts.). Pignoli of course are good, but fresh walnuts, briefly pan-toasted and then crushed, can add real flavor too. Sesame seeds also work: toast them in a hot pan, then they crush easily in a mortar or etc. and add great flavor.

                                      FYI the "Roland" brand of condiments includes what I thought was a very decent commercial pesto sauce, mercifully not oversalted, and sold in large (one kG?) jars for restaurant service at Smart & Final (which doesn't _quite_ call itself the "Smaller, faster Costco"). Hotrodded with a little fresh garlic, toasted nuts, Reggiano, and fresh basil if available, then frozen in convenient portions, it has made a very agreeable pesto sauce indeed.
