Staub Sesame 3 pcs Rectangular Baking Dish Set
Lower concern. Enameled cast iron rarely uses PFAS, but brand is silent.
Staub baking dishes use enameled cast iron, which typically avoids Teflon-family coating coatings used in nonstick cookware. Staub makes no PFAS disclosure, so verify directly with brand if concerned.

The full breakdown
What it's made of and why it matters
This set consists of cast iron cores with vitreous enamel coatings in dark (likely black or charcoal) glaze. Cast iron itself is inert and durable; the enamel layer prevents direct iron-to-food contact and eliminates rust risk. Dark enamels on cookware have not been linked to lead or cadmium leaching in modern manufacturing, though older vintage pieces sometimes contained these metals in decorative glazes. Staub is a premium French brand (now owned by Zwilling) with industrial enameling standards.
The brand's record and disclosure
Staub does not publicly disclose detailed enamel composition or third-party safety testing results on their website, which is typical for cookware brands. No major safety recalls, lead warnings, or enamel degradation complaints are on record for this product line. The brand is well-regarded for durability and has maintained consistent manufacturing in France for decades, suggesting stable quality control. Their silence on PFAS is neither unusual nor a red flag for enameled cast iron, which rarely employs perfluorinated coatings.
How it compares in its category
Enameled cast iron is among the safest cookware materials available, with no non-stick coating degradation concerns (unlike Teflon-type coating) and no aluminum leaching risk (unlike bare aluminum). This product sits at the premium end; similar sets from Le Creuset, Tramontina, and Lodge offer comparable safety profiles at lower price points. The dark enamel finish is standard across this category and carries no documented hazard advantage or disadvantage over colored enamels.
If you buy it
Avoid sudden thermal shock; preheat gently and cool slowly to prevent enamel crazing. Do not use metal utensils that scratch the enamel surface, as small chips expose iron (harmless but cosmetically undesirable) and concentrate wear. Hand-wash rather than machine-wash to extend enamel life. Enameled cast iron can safely reach oven temperatures up to 500F (check your manual); the enamel does not degrade or off-gas at typical baking temperatures.
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
Modern enameled cookware, especially from established brands like Staub, does not use lead or cadmium pigments. No recalls or test results indicating contamination are on record for this product line.
Enamel crazing and chipping
Thermal shock (rapid heating or cooling) can cause hairline cracks in the enamel, exposing iron underneath. This is a durability and cosmetic issue rather than a direct health hazard, but prolongs product lifespan with careful use.
Iron leaching from exposed substrate
If enamel is chipped or abraded by metal utensils, small amounts of iron may leach into acidic foods. Iron is an essential nutrient and poses no toxicity risk at typical leaching levels; this is mainly a concern for iron-sensitive individuals or those with iron overload disorders.
Teflon-type coating or non-stick coating degradation
This product uses vitreous enamel, not Teflon-type coating or silicone non-stick coatings. No fume risk or microplastic shedding applies.
Formaldehyde or volatile off-gassing
Enameled cast iron does not employ formaldehyde-based resins or coatings. No off-gassing is expected during normal use or heating.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
