Williams Sonoma Stainless-Steel Outdoor Pizza Pan
Lower-concern cookware; stainless steel is not associated with PFAS without explicit brand disclosure.
Stainless steel pan with no nonstick or Teflon-family coating treatments required. Williams Sonoma offers no PFAS disclosure, but the material itself carries lower PFAS risk than coated cookware.

What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Thermal damage or warping
Stainless steel can warp under extreme or uneven outdoor heating, particularly at thinner gauges. This affects performance but not food safety. Choose thicker gauges and avoid rapid temperature changes.
Surface corrosion and pitting
Outdoor stainless steel can develop surface corrosion or pitting if exposed to salt spray, de-icing salts, or prolonged wet conditions without drying. This is cosmetic and does not contaminate food but can shorten product life.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Metal leaching (chromium, nickel)
Stainless steel 300-series alloys used in cookware are formulated to remain stable under cooking heat and acidic food contact. No public recalls or testing data indicate leaching from Williams Sonoma stainless cookware into food.
Coating degradation and peeling
Stainless steel pizza pans have no applied coating; the material itself is the cooking surface. There is no peeling risk, unlike enameled or non-stick alternatives.
Aluminum or steel substrate unknown composition
No public information indicates a hidden aluminum core or non-food-grade substrate in this product. Williams Sonoma cookware is generally sourced from established manufacturers, but detailed alloy certification is not publicly disclosed.
The full breakdown
What it's made of and why it matters
This pan is constructed from stainless steel, a chromium-iron alloy that is inherently non-reactive and does not leach metals into food under normal cooking conditions. Stainless steel forms a passive oxide layer that resists corrosion and chemical migration, which is relevant to cookware performance. Unlike non-stick coatings or glazed ceramics, stainless steel cookware carries no risk of peeling, degradation, or release of synthetic polymers or heavy metals over time.
The brand's record and disclosure
Williams Sonoma does not publish detailed material safety disclosures or third-party certifications for this cookware product. The brand has no established public record of cookware-related safety recalls or ingredient controversies in peer-reviewed sources or major consumer databases. As a home furnishings and culinary brand, Williams Sonoma is generally responsive to product safety concerns but does not volunteer detailed chemical composition or coating source documentation for outdoor cookware.
How it compares in its category
Stainless steel pizza pans present lower concern in the pizza cooking category compared to ceramic pizza stones (which can contain lead or cadmium in decorative glazes) and commercial non-stick pans (which carry Teflon-type coating fume risk if overheated). Cast iron alternatives require seasoning maintenance and can leach iron in acidic foods, while this material avoids both concerns. The outdoor-rated designation suggests corrosion-resistant stainless (likely 304 or 430 grade), which is standard for this application.
If you buy it
Wash with mild soap and water before first use to remove any manufacturing residue. Stainless steel can heat unevenly, so preheat thoroughly and watch for hot spots during pizza cooking. Avoid prolonged contact with salt or acidic sauces sitting on the surface when not in use, as stainless can pit under extreme conditions. No special replacement timeline is needed if cared for; stainless steel pizza pans typically outlast the user and require no coating renewal.
