Cast Iron Square Grill Pan Staub
Lower concern, cast iron with enamel is a traditional PFAS-free cookware choice.
Staub square grill pans are cast iron with enamel coating, a well-established cookware material class without modern PFAS-based nonstick treatments. The brand does not publicly disclose PFAS testing or claims, but the material itself, uncoated cast iron and vitreous enamel, carries no inherent PFAS risk.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
Staub square grill pans are cast iron with a vitreous enamel (glass-like) coating, typically in dark colors like black or cherry. The enamel is fused at high temperature directly to the iron surface, creating a non-porous barrier that prevents iron leaching into food and eliminates the need for seasoning oil maintenance. This manufacturing method is one of the oldest cookware technologies and does not rely on Teflon-type coating or synthetic coatings that off-gas when overheated.
The brand's record and disclosure
Staub, owned by Zwilling J.A. Henckels (German heritage cookware company), maintains no public PFAS disclosure statements but also has no documented use of PFAS in their enamel formulations. The brand carries no major product recalls related to coating contamination, lead leaching, or hazardous chemical release. Staub products are sold in premium kitchenware channels and certified by EU and North American cookware standards, though specific third-party material certifications are not prominently advertised.
How it compares in its category
Staub's enamel-on-cast-iron design is comparable to Le Creuset and Lodge enameled cast iron, representing the safest cookware segment for chemical hazards because the enamel creates a complete barrier. Nonstick grill pans (Teflon-type coating or ceramic) carry fume and coating-shedding risks; uncoated cast iron requires oil maintenance but poses no coating degradation concern. Staub's price point reflects durability and heritage but is significantly higher than budget enamel brands, which may use lower-quality glaze formulations.
If you buy it
Avoid preheating empty above 500°F, as extreme heat can stress the enamel seal at edges, though standard stovetop and oven use to 400°F poses no risk. Hand wash and dry immediately to prevent water spotting and rust at any chip sites; chips in the enamel exposing bare cast iron will begin to rust and should trigger replacement or professional recoating. Use on all cooktop types including induction; the heavy mass makes it excellent for grill marks but slow to heat. Store without stacking to prevent chipping.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Lead or cadmium in enamel glaze
No public recalls or testing reports of lead/cadmium contamination in Staub enamels. EU manufacturing standards and premium brand positioning make this unlikely, but independent third-party testing results are not publicly available.
Enamel coating degradation and iron leaching
Thermal shock cracking
Rapid temperature changes (cold water on hot pan) can cause small enamel cracks from differential expansion. This is a handling issue, not inherent to Staub's formulation; proper care (gradual cooling) eliminates this risk.
Teflon-type coating or nonstick coating fumes
Enamel is vitreous (glass-based), not Teflon-type coating. No polymer fume risk even at high heat; traditional enamel remains chemically stable on stovetop and in standard ovens.
Aluminum or other metal leaching from substrate
Cast iron cookware contains no aluminum. Iron leaching only occurs if enamel coating is compromised, which is a visible, avoidable condition.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 82% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
