Costco is more than just a warehouse—it’s practically a way of life. Shoppers flock there for the towering pallets of pantry staples, delicious food court finds, and beloved Kirkland Signature items that often rival or surpass brand-name products.
But while the warehouse giant has earned a reputation for high-quality goods at wallet-friendly prices, not every item is a winner. For every product that sparks joy in your taste buds, there’s another that leaves customers scratching their heads—or worse, reaching for the return counter.
From surprisingly underwhelming deli items to snacks that taste more like cardboard than comfort, even Costco isn’t immune to a misstep or two.
Some products look amazing on the shelf but disappoint when it’s time to eat. Others have changed over the years—shrinking in size, increasing in sodium, or just losing that original magic.
Still, it’s not all doom and gloom. There are those Costco food items that inspire genuine cult followings. We’re talking about the ones people recommend without hesitation, the ones that fill carts every single trip, and the ones that spark Reddit threads full of glowing praise.
These are the consistent hits—flavorful, satisfying, and undeniably worth the membership. In this article, we’re diving into both sides of the Costco food aisle.
We’ll highlight six items that get the most customer complaints—whether it’s for flavor, texture, or a recent change that didn’t sit well with fans. Then, we’ll redeem the mood with six Costco food staples that nearly everyone agrees are absolute standouts.
Whether you’re a longtime Costco member or just sizing up that $1.50 hot dog deal, this list will help you shop smarter—and maybe save you from a bulk-sized letdown.
1. Kirkland Signature Rotisserie Chicken
At first glance, the Kirkland Signature Rotisserie Chicken seems like a winner. Its golden-brown skin and appealing aroma tempt countless shoppers. However, some find it less appetizing due to its overly salty taste and greasy texture.
Reports of an artificial flavor only add to the criticism. Customers also complain about inconsistent texture and undercooked batches, which are real deal-breakers for some. While it’s a staple for many, others might think twice before adding it to their cart.
For those who enjoy it, the convenience and price might outweigh the complaints. If you’re adventurous, give it a try and see which side you fall on. It’s a love-it-or-hate-it item that has sparked numerous culinary debates.
2. Kirkland Signature Canned Chicken Breast
Opening a can of Kirkland Signature Canned Chicken Breast is like opening a can of mystery for some. While it’s packed with protein, customers frequently criticize it for being dry and stringy.
The contentious texture isn’t the only issue; many report a strange smell emanating once the can is opened. This, combined with its mushy consistency, can make it unappealing for those seeking a quick meal solution.
Despite the criticisms, it’s a convenient pantry staple that may work well in a pinch. If you’re not too picky, it might just suit your needs. However, those sensitive to taste and texture might want to steer clear. It’s a mixed bag of reviews that keeps people talking.
3. Kirkland Signature American Cheese Slices
Cheese lovers might approach Kirkland Signature American Cheese Slices with a bit of caution. While the idea of a budget-friendly cheese slice is appealing, many find the taste to be artificial.
The texture is often described as rubbery, which doesn’t bode well with those who savor the meltability of their cheese. Comparing unfavorably to name-brand alternatives, these slices might not be the top choice for a gourmet grilled cheese.
However, for everyday sandwiches and quick snacks, they still have an audience. If you’re looking for a simple slice to toss on a burger, they might do the trick. It’s all about expectations when it comes to this cheesy contender.
4. Costco Fresh Salmon
Costco’s Fresh Salmon often draws a crowd, with many appreciating its rich flavor and vibrant appearance. Despite its popularity, some customers have encountered issues.
Complaints about a strong “fishy” odor are not uncommon, raising concerns about freshness. Additionally, inconsistencies like bones in the fillet can detract from the overall experience.
For many, the quality and price make it a staple in their weekly meals. However, those with sensitive noses or a keen eye for bones might find it less appealing. It’s a product that has both enthusiastic fans and vocal critics, making it a topic of debate among seafood lovers.
5. Kirkland Signature Greek Yogurt (Plain)
Plain Greek yogurt is a healthy choice, but Kirkland Signature’s version can be polarizing. While it’s nutritious, some say it’s too tart for their palate.
The texture, described as chalky or watery after stirring, isn’t to everyone’s liking. This creates a divide between those who appreciate its health benefits and those who crave a smoother experience.
It’s perfect for adding to smoothies or topping with fresh fruit and honey. Yet, for those sensitive to taste and texture, it might be a pass. Health-conscious shoppers will find it appealing, while others might keep searching for their perfect yogurt match.
6. Costco Bakery Muffins
Costco Bakery Muffins are a treat that draws both fans and critics. Their jumbo size and tempting flavors make them an enticing choice for a quick breakfast or snack.
However, these muffins are frequently criticized for being “sugar bombs,” with nutrition facts that may surprise those expecting a healthier option. While they delight taste buds, their caloric content is a sticking point for health-conscious consumers.
For those who indulge without worry, they are delicious and satisfying. If you’re watching your sugar intake, they might be an occasional treat rather than a daily choice. It’s a classic case of taste versus nutrition that sparks lively conversations among shoppers.
7. Kirkland Signature Extra Virgin Olive Oil
