Longtime customers may consistently reach for favorites like the Kirkland Signature Turkey Jerky, Sheila G's Brownie Brittle, or the famous food court pizza.

With every new month (or season), members can expect to find plenty of fresh additions to the retailer's grocery lineup. Some of the hottest new foods to land at Costco in 2026 alone include everything from Vietnamese coffee ice cream to sparkling energy drinks to heat-and-eat bags of frozen chicken wings.

Made from durum wheat semolina and cage-free eggs, Al Dente's artisan pasta is packed with 30 grams of protein and 14 grams of fiber per serving. It also claims to have 40% less net carbs than regular pasta brands. One reviewer liked how this high-protein product held its shape in casseroles, rather than getting mushy. Another said they didn't experience "the typical carb crash" they usually get after eating pasta. This six-pack features both cavatappi and rigatoni, two shapes that go great with rich sauces and melty cheese.

Described by a Costco member as "light, refreshing, and easy to drink without being overly sweet or strong," this organic iced black tea is brewed, bottled, and ready to sip.
