Costco Just Added a Bunch of Sweet and Savory Food Options for May 2026!

Costco runs can be overwhelming, with crowded stores and so many products to choose from. But things are definitely easier when you know what you want to get ahead of time. And shopping trips are super satisfying when you discover new favorites throughout the store.

Costco just made stocking the pantry a little more interesting, having released some tasty snacks and other yummy food items in May of 2026. Here's what we know about Costco's newest food products.

Costco is now selling frozen mango on a stick, which makes for a sweet and healthy snack. You can get a pack of 14 for $13. They also now carry Jeni's key lime pie frozen dessert sandwiches.

The frozen treats have a layer of tart key lime ice cream between two graham cracker cookies. A pack of 8 goes for $14.50.

Costco's new sweet and salty cookies consist of pretzel pieces, caramel chunks, and chocolate chips in a brown-butter cookie dough base. Score a package of 24 for $10.99.

According to @costco_empties, the chain also released a strawberry cream pie and a quiche lorraine with ham and bacon.

On the strictly salty side of things, Costco also released Kirkland Signature sea salt popcorn as well as Doritos protein chips. You can get 36 single-serving bags of the popcorn for just $10, and one 13-serving bag of the protein Doritos for $6. The protein Doritos have 10 grams of protein per serving!

One Costco customer wrote on Reddit that the protein Doritos are the only protein chips they've tried that actually taste like a regular chip(but thicker).

On social media, Kirkland's new ultra-filtered, lactose-free, reduced-fat milk is being compared to Fairlife's ultra-filtered, lactose-free milk. However, Costco's product is much cheaper per gallon.

Next time you fire up the grill, swing by Costco first to grab their new cilantro-lime marinated flank steak. It comes with an extra side of cilantro lime sauce.

Costco has carried Olipop products before, but they now have a limited edition Spring variety pack, featuring raspberry sherbet, Shirley Temple, and strawberry vanilla flavors.

Olipop sodas contain plant fiber, prebiotics, and botanicals, which support gut health and digestion, per Olipop's website.

And if you're feeling adventurous, check out their new blueberry sourdough bread loaf. It's reportedly packed with blueberries, and you'll get 2 pounds of bread for $9. Costco customer @brialem said that the bread is not super sweet, but it still feels like a treat.

Costco rolls new products out gradually, so don't worry if you don't see these new items at your local store just yet.
