Some Costco finds feel like they weren’t supposed to end up in your cart at all — and that’s exactly the energy around King’s Hawaiian’s new Savory Butter Slider Buns. These buns were built for restaurant kitchens, not warehouse shelves, which is precisely why shoppers are losing it over spotting a bag between the regular sweet rolls and the rotisserie chickens.
What Are King’s Hawaiian Savory Butter Slider Buns?
King’s Hawaiian built its entire brand on sweetness, so this is a genuine plot twist. The Savory Butter Buns swap the classic sugary dough for a richer, more savory recipe loaded with real butter, eggs, and dairy — landing somewhere between a pillowy dinner roll and a proper brioche bun. They debuted as a foodservice-exclusive item at the National Restaurant Association show, meant for smashburgers, fried chicken sandwiches, and diner-style melts where the bread actually needs to hold its own.
Translation: this bun wasn’t supposed to show up next to your groceries. But it did.
Why Costco Shoppers Are Freaking Out
Shoppers have now spotted the Savory Butter Slider Buns at more than 50 Costco warehouses, with the biggest concentration in California so far. At about $6 a package, they’re a steal for a bun that restaurants are quietly paying premium foodservice pricing for. Costco fans are stocking up specifically because nobody knows how long the run will last — once a “spotted, not officially confirmed” item disappears from Costco shelves, it rarely comes back on a predictable schedule.

How To Snag a Pack Before They Vanish
Since this isn’t a nationwide, officially promoted launch, availability is spotty and very much a “check your local warehouse” situation. Head to the bakery or bread section near the regular King’s Hawaiian rolls, and don’t expect a sign pointing you to it — this is the kind of find you stumble into, not one Costco is shouting about. If your warehouse has it, grab more than one pack. Shoppers who’ve already found it say it sells out fast once word spreads on social media.
What To Make With Them
These buns are built for anything richer than a basic burger. Think pulled pork, smashburgers, breakfast sandwiches, or crispy fried chicken sliders for your next cookout. If your warehouse is out of stock, Aldi’s Hot Honey Brioche Buns are a worthy stand-in with their own spicy-sweet twist. Pair either one with a haul from Aldi’s Grill Master Collection for a full backyard spread, and save room for dessert with Costco’s viral Pistachio Croissants while you’re at it.
Bottom line: if you spot King’s Hawaiian Savory Butter Slider Buns at your Costco, don’t overthink it — toss a pack (or three) in the cart. Restaurant-grade bread for $6 a bag is the kind of deal that doesn’t wait around for you to come back later.
