Top 10+ Kirkland Signature Products Worth Having A Costco Membership For

These products will make every penny of your Costco membership worth it.

The allure of strolling the aisles of Costco is to save money on some of your most-used household items. Like other warehouse stores, Costco has an in-house brand, Kirkland Signature, they use to sell products at even more affordable prices for consumers.

While you’ll no doubt get a great deal on Kirkland Signature paper towels and toilet paper, and you can't beat their premade meals for feeding a crowd, there are some hidden gems throughout the warehouse that we flock to over and over again. In fact, every product on this list has been marked as a favorite by consumers. We’ve rounded up the top Kirkland Signature products to check out the next time you head to Costco.

Greek yogurt is often recommended as a healthy way to start the day thanks to its nutritional components, and Costco’s version checks all the boxes for half the price. Rich in protein, calcium, and potassium, Kirkland’s Greek Nonfat Yogurt sells for less than $8 for a 48-ounce tub.

Kirkland Signature Extra Virgin Italian Olive Oil

Kirkland’s Extra Virgin Olive Oil is consistently rated a bestseller and a favorite among shoppers for both quality and price. A 2-liter bottle runs about .47/ounce compared to premium olive oils that can get up to $2/ounce. Cold pressed and produced from Italian olives, it’s one of the best deals in the entire warehouse.

Kirkland Signature Italian Parmigiano Reggiano

One of the world’s best cheeses…by Kirkland? You bet. For $15/pound (compared to up to $40/pound at premier cheesemongers), Kirkland Signature Italian Parmigiano Reggiano checks both boxes when looking for this beloved cheese: the Parmigiano Reggiano stamp on the rind of the cheese and the consortium logo, which appears as a wedge of cheese on the label.

Kirkland Signature Organic Maple Syrup

Reddit users go crazy for Kirkland Signature’s Organic Maple Syrup and have a pretty lofty claim: “It's cheaper than what I bought when I lived in Vermont.” Currently retailing for $14.99, the grade A amber syrup is 100% pure maple syrup that gets tapped in Canada (specifically maple trees in Quebec) between March and April. For the real stuff, you won’t find a better deal.

Kirkland Signature Imported Basil Pesto

A 22-ounce jar of pesto using 100% imported Italian basil sounds like more pesto than one might ever need. It’s true—you definitely get your money’s worth for around $11 per jar—but the real joy in this Kirkland Signature find is being able to freeze what might be on the verge of going bad. A Costco employee tells Southern Living she puts her Kirkland pesto in ice cube trays to freeze before placing the cubes into a freezer-safe plastic bag to use as needed.

Kirkland Signature Chocolate Covered Raisins

For only $22.99 you can get nearly 3 1/2 pounds of raisins coated in creamy milk chocolate, which may seem like a lot. But Reddit users claim that not only are they “better than Raisinets,” but that the chocolate is rich and the raisins stay plump. “I eat them by the handful until I’m sick,” wrote one user. Okay, maybe don't go that far.

Kirkland Signature Grass-Fed Butter

Nothing makes a recipe taste more delicious than adding Kerrygold grass-fed butter, but it can be cost prohibitive to stock up on the brand’s popular grass-fed butter at around $1.60/ounce. Kirkland’s Signature Grass-Fed Butter comes in at around .80/ounce and in our opinion, tastes richer. A side-by-side comparison of ingredients showed that Kirkland’s grass-fed butter has marginally lower sodium—and it's produced in New Zealand. 

Kirkland Signature Butter Croissants

The bakery section at Costco is a national treasure of freshly baked cakes, pies, desserts, and bread, not to mention multipacks of bagels and breakfast pastries. But the crown jewels of Costco’s bakery are the Kirkland Signature Butter Croissants, which come in a pack of 12. A single large, flaky croissant at a diner or coffeeshop is usually around $4, so to get a dozen for about $7 is a steal. At just $.60/each, one Reddit user put it best, “Seriously, the croissants. They're almost enough to justify a membership by themselves."

Kirkland Signature Vodka

One stroll through the alcohol section of a Costco that carries it (sorry to report, not all Costcos are legally able to distribute booze), and you’ll notice that Kirkland branded alcohol is a steal. You may also notice how similar the bottles look to more popular (and expensive) brands. Long rumored to be produced by Grey Goose, Kirkland Signature Vodka ($22 for a handle) is a cut above the rest. While Grey Goose—sold for $40 to 50 per bottle—has put the rumor to rest, it has a smooth and crisp taste that makes professional and at-home bartenders clamor for a bottle.

Kirkland Signature Super Premium Vanilla Ice Cream

One Reddit user said they had to stop buying this after they gained 10 pounds, and another called the texture a dead ringer for Cold Stone Creamery. A thick vanilla ice cream with a true vanilla flavor, two half gallons (four quarts) are priced at $18, compared to an average of $4 to 7 for a much smaller container at a grocery store. The only real problem is finding storage space!
