Navigating the aisles of a major warehouse store can be challenging for anyone, but for those following a gluten-free diet, it requires extra scrutiny and planning. Both Costco and Sam's Club offer bulk-sized savings, but their approach to stocking specialty dietary items, particularly gluten-free products, differs significantly.
The Gluten-Free Landscape at Costco
Costco is widely recognized among the gluten-free community for its broader and often more consistent selection of certified and labeled gluten-free items. The visibility of organic products is also a strong point, with many of these overlapping with gluten-free needs.
Notable Costco Gluten-Free Products
Costco’s strength lies in both its well-curated national brands and a strong, growing line of Kirkland Signature items. Here is a look at some popular categories:
- Pantry Staples: Costco regularly carries staple items like gluten-free pasta (often Barilla brand), King Arthur Measure for Measure flour, and large bags of almond flour. Kirkland Signature Organic Quinoa is a reliable, budget-friendly option.
- Snacks: The snack aisle offers a wealth of choices. Shoppers can find Crunchmaster crackers, KIND bars, and Siete brand grain-free tortillas. Kirkland Cashew Clusters are another popular gluten-free snack.
- Frozen Foods: The frozen section is a major draw for prepared gluten-free items. A long-standing favorite is the gluten-free full-size cheese pizza, along with other items like cauliflower crust pizza and a variety of gluten-free burgers.
- Fresh and Meat: For protein, Costco offers labeled gluten-free options like their famous rotisserie chicken. The fresh produce selection is typically extensive and a naturally safe choice for gluten-free diets.
Considerations for Costco Shoppers
While the variety is a plus, shoppers must remain vigilant. The food court is not a safe haven for those with celiac disease due to high cross-contamination risk. Moreover, the inventory of specialty products is constantly changing, so a favorite item may disappear without notice. Always read labels, especially on prepared foods from the deli, which may be processed in a shared facility.
Sam's Club's Expanding Gluten-Free Selection
For many years, Sam's Club was considered to have a much more limited gluten-free selection compared to Costco. However, recent years have seen a significant increase in their offerings, though they still lag behind Costco in overall variety.
Notable Sam's Club Gluten-Free Products
Sam's Club, with its parent company Walmart's push for more dietary-friendly options, has expanded its Member's Mark and national brand selection. Popular finds include:
- Pantry Staples: Sam's Club offers a solid lineup of basics, including Barilla gluten-free pasta and Krusteaz gluten-free baking mixes.
- Snacks: Snack offerings feature brands like Crunchmaster and Sensible Portions, along with a wide variety of chips, nuts, and dried fruits under the Member's Mark label.
- Frozen Foods: The freezer section has seen improvements, with gluten-free cauliflower crust pizzas becoming a more consistent item. Other options like Feel Good Foods egg rolls have been spotted.
- Fresh and Meat: Like Costco, Sam's Club has naturally gluten-free fresh produce, and many of their Member's Mark meats, like the bacon ranch chicken burgers, are clearly labeled as gluten-free.
Considerations for Sam's Club Shoppers
While the expansion is welcome, variety can be inconsistent, and regional variation can be quite pronounced. Sam's Club's online shopping offers a larger selection and allows non-members to shop for a small service fee. However, the in-store experience might be less robust for gluten-free seekers compared to Costco.

Making the Right Choice for Your Gluten-Free Lifestyle
The best warehouse for your gluten-free needs often comes down to your personal priorities. If you are looking for the maximum variety of certified and specialty gluten-free brands, plus a reliable private-label line, Costco is the superior choice. Their strong presence of brands like Siete and Simple Mills, alongside their own Kirkland offerings, makes them a destination for dedicated gluten-free shopping.
On the other hand, if you are a more casual gluten-free shopper or live in an area with a strong Sam's Club presence, their growing selection is worth exploring. It's especially useful for basic pantry items and certain frozen meal options. Remember to always check the latest offerings online or use the store's app before making a trip, as inventory can and does change.
Regardless of your choice, a key aspect of successful gluten-free warehouse shopping is meticulous label-reading. Even products that seem safe should be checked, as formulations can change over time.

Conclusion: Which Warehouse Wins for Gluten-Free Shoppers?
Based on a consensus among gluten-free shoppers and recent product trends, Costco generally offers a more robust and diverse selection of gluten-free products than Sam's Club. From established private-label items to a broader range of national specialty brands, Costco provides a more comprehensive gluten-free shopping experience. While Sam's Club is making strides in expanding its gluten-free offerings, Costco remains the leader for variety and consistency. However, since inventory is regional and constantly evolving, the best strategy is to check the websites and local forums for both stores to see what options are currently available near you before committing to a membership.
