Costco is known for its incredibly varied catalog, with many brands for its members to choose from. However, some argue that the very best items at Costco are produced by the store's private label, Kirkland Signature. Since Costco first introduced it more than 30 years ago, Kirkland Signature has grown to become one of the biggest consumer packaged goods brands in the United States in terms of sales and continues to impress Costco members each year with exciting new products. Seeing as 2026 is nearing its end, it feels like the right time to look back at the year and discuss some of the very best Kirkland Signature creations from this calendar year.

From January until now, Costco has been pumping out new items in its bakery, deli, food court, and beyond, many of which have been big hits among the store chain's massive fanbase. Due to many Kirkland Signature items being seasonal, some of the entries on this list are no longer available on Costco shelves, but were still included due to how noteworthy they were during their time at the store.

Starting things off with one of the few new beverages that Costco's private label came out with this year, the Kirkland Signature Sparkling Energy Drinks have been a big hit among Costco consumers since their release in March. The sugar-free drink comes in 24-packs that feature tropical, peach, and orange flavors, giving consumers some variety with every purchase. Plus, the Kirkland Signature product is similar to brands like Celsius, so its tasty flavor and low price are incredibly appealing to many energy drink fans.

The popularity of matcha in the United States has grown massively in recent years, and Costco is responding to the demand with Kirkland Signature Japanese Matcha Green Tea Powder. It was announced as a key new item for the private label last September during the recent Costco earnings call and has already gotten plenty of positive feedback from members. "I think it's perfect," one Redditor admitted. "The best way I can describe it is 'light.' It has a full matcha flavor with the right amount of bitterness."

Moving on to the only Kirkland Signature Food Court item to make this list, the long-awaited introduction of chicken strips at Costco was announced last May, eventually reaching stores nationwide by July. While the chicken hasn't been everyone's cup of tea (our own writer was less than impressed in his review of Costco's chicken fingers), it has left a positive impression on those looking to change things up at the iconic food court. Plus, the serviceable chicken strips are an incredible value and come with a sauce that many online have compared to Chick-fil-A's iconic dip.

It goes without saying that store-bought frozen fish can generally be pretty hit-or-miss in terms of quality, but many believe the new Kirkland Signature Atlantic Blackened Salmon is about as good as it gets. The salmon was announced as one of the private label's newest products by Costco back in March, and quickly impressed the masses with its immense juiciness and flavor. While the salmon's packaging notes that you can defrost the fish before cooking, some consumers online said throwing it directly into the oven or air fryer can produce very strong results all the same.

Going all the way back to January, the Costco deli section rolled out the tasty Kirkland Signature Pesto Pasta Salad. The ready-to-eat product features trottole noodles, roasted tomatoes, arugula, basil pesto, and mozzarella pearls, with the tomatoes, in particular, being the star of the show for some customers. The biggest hang-up for many was the price, as the deli item costs $5.99 per pound — about $20 per container.

The Kirkland Signature Pesto Pasta Salad was unfortunately a relatively short-lived item this year and is no longer available at Costco. However, seeing as Costco often brings back Kirkland Signature products after a while, you should be on the lookout for its potential return in the future.

Few things are as vital on a shopping trip as a tasty snack, and the new Kirkland Signature Sea Salt Popcorn was on our list of the best new Costco snacks of 2026. Fans have been touting its greatness, too. "They have a buttery consistency, and they melt in your mouth," praised one Redditor, while others noted that the snack's use of coconut oil is a major reason why it tastes so good. Nevertheless, the savory treat is sold in bulk, with 36 small bags in a box, making it the perfect snack to share with others.

The summertime delight that is the Kirkland Signature BBQ Chicken Mac and Cheese with Bacon was sold in Costco's deli section beginning in June. Unparalleled among the store's other heat-and-eat dishes, this item delivered a very nuanced flavor by incorporating chicken, barbecue sauce, and bacon into a creamy mac and cheese base. The biggest issue with the deli item is its availability, as it is a revolving item and is currently out of stock in many markets across the country. Nevertheless, if you can find the summertime standout, the BBQ Chicken Mac and Cheese with Bacon costs $5.10 per pound, about $20 total.

Moving on to one of the delectable new bakery items at Costco, the Mini Pains Au Chocolat produced under the Kirkland Signature label is the perfect treat for breakfast or dessert. First discovered by Costco members back in August, the new item takes croissants (a popular Kirkland Signature staple), shrinks them into a bite-sized pastry, and stuffs them with chocolate to make any customer with a sweet tooth happy. Each container includes 20 pastries, and some online say it's hard to avoid eating them all up in just a day or two.

One style of dessert that has become a bona fide classic at Costco is the bar cake, and this year's Kirkland Signature Pumpkin Spice Bar Cake stands out from the other versions. It was first spotted at Costco in August and is the newest bar cake at the store at the time of this writing. However, this isn't just recency bias; the dessert utilizes both pumpkin cake and pumpkin cream to deliver an incredibly fall-heavy flavor. Plus, at roughly 2.5 pounds, the cake is perfect for sharing with others or enjoying yourself over the span of a few days.

It's hard to discuss Kirkland Signature products without bringing up the store's alcohol section, full of high-quality, low-cost liquors and wines. In particular, the Kirkland Signature Bordeaux Blanc appears to be the only brand-new wine at Costco this year. The warehouse announced this offering last April, adding to Costco's "gold mine" of Bordeaux wines. It's praised for its refreshing, fruity taste and low price of just $6.99. Due to Bordeaux primarily being known for its red wines, the Bordeaux Blanc is especially notable.

Unfortunately, the wine is currently out of stock at most Costco locations. But keep an eye out for a bottle of the exclusive wine during your future trips to Costco, and maybe you'll get to find out what all the hype is about.

The new Pretzel Bagels at Costco are among the strongest upgrades of a pre-existing Kirkland Signature item we've seen all year. First spotted back in June, the Costco Pretzel Bagels were immediately sought after by store members and have already become a staple of many shoppers' grocery lists. Beloved for their soft texture and more pronounced flavor, the new pretzel variant is one we hope remains at Costco for the foreseeable future.

Speaking of pretzels, the final item on this list is another pre-made dish available in Costco's deli section. The Kirkland Signature Chicken Sandwiches on Pretzel Buns are miniature sandwiches with deli-style chicken, Swiss and cheddar cheese, and lettuce, all contained within a pretzel bun. This product was first spotted back in August, and each container features six small sandwiches. Plus, the Dijon mayonnaise that comes alongside the sandwiches puts the already-tasty Costco product on another level.
