Discovering the Costco Gluten-Free Pizza Makers

For many shoppers with celiac disease or gluten sensitivities, Costco's array of frozen food options is a lifesaver. When it comes to frozen pizza, the mystery of who stands behind the product's quality is a common point of curiosity. Research into the product labeling and Costco's supplier relationships reveals that there are two primary answers to the question of who makes Costco gluten free pizza, depending on the specific product.

Sabatasso's: The Classic Thin & Crispy Crust

One of the most recognized and celebrated gluten-free pizzas at Costco is the four-cheese, thin and crispy crust version, which is produced by the Sabatasso's brand. Sabatasso's has a long-standing reputation for quality frozen pizzas, and their gluten-free offering has been a hit with Costco customers for its flavor and convenient, multi-pack format.

Flavor Profile: The Sabatasso's pizza features a blend of mozzarella, fontina, parmesan, and asiago cheeses over a thin, crispy crust and a vine-ripened tomato sauce.
Ingredient Transparency: The packaging clearly lists the ingredients, which include tapioca starch and rice flour for the crust, making it a safe choice for many gluten-free consumers.
Availability: While a popular item, the availability of Sabatasso's gluten-free pizza can vary by region and season. The item has been intermittently stocked in the past, leading to requests from dedicated fans for its consistent return.

Kirkland Signature: The Cauliflower Crust Revolution

In recent years, Costco's own Kirkland Signature private label has expanded its gluten-free pizza offerings to include cauliflower crust varieties. This development provides members with a vegetable-based, lower-carb alternative to traditional grain-based gluten-free crusts. The suppliers for Kirkland Signature products are not always publicly disclosed, but they are vetted by Costco to meet quality standards. The specific manufacturers for the Kirkland Signature cauliflower crust pizzas may differ depending on the specific product variation (e.g., supreme vs. cheese) and region.

Product Variants: Costco has carried several versions of the cauliflower crust pizza, such as the Supreme and Roasted Vegetable flavors.
Supplier Details: While the exact manufacturer behind the Kirkland Signature name is proprietary, these products are still a certified gluten-free alternative, offering peace of mind to consumers with dietary restrictions.

Is Costco's Gluten-Free Pizza Safe for Celiacs?

For individuals with celiac disease, verifying that a product is genuinely gluten-free and free from cross-contamination is critical. Both the Sabatasso's and Kirkland Signature products typically meet strict standards.

Sabatasso's Certification: Sabatasso's has historically been certified by recognized organizations, such as the National Celiac Association, which involves third-party testing for gluten content. This certification is a strong indicator of safety for those with celiac disease.
Kirkland Signature Standards: As a private label brand, Kirkland Signature relies on its suppliers to follow rigorous protocols. The product packaging or manufacturer's website (if identifiable) is the best source for finding specific certification details. Many members on online forums report no issues after consumption, even those with high sensitivity, suggesting robust protocols are in place.
