Le Creuset Muffin Tray
Lower-concern choice; enameled cast iron is a traditional, PFAS-resistant material.
Le Creuset muffin trays are made from enameled cast iron, a vitreous enamel coating fused to cast iron, which does not rely on fluorinated compounds. This material class has no established PFAS concern. Le Creuset does not market PFAS-free claims, but the material itself presents lower risk than modern nonstick coatings.

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
Le Creuset muffin trays are cast iron with a vitreous enamel (glass-like) coating applied at high temperature. This enamel layer is chemically inert once cured and does not rely on fluorinated compounds (PFAS) for non-stick or water resistance, unlike many modern non-stick coatings. The cast iron base itself is durable and does not leach in normal use; the enamel acts as a complete barrier between the metal and food.
The brand's record and disclosure
Le Creuset does not publicly disclose detailed chemical composition or third-party testing results for enameled cookware, which is typical for heritage cookware brands. No major recalls or established contamination incidents involving Le Creuset enameled cookware have reached public health databases. The brand's long manufacturing history (since 1925) and premium positioning suggest quality control, though proprietary enamel formulations are not independently verified.
How it compares in its category
Enameled cast iron muffin trays occupy a middle ground: they avoid Teflon-type coating (Teflon) fume risk present in non-stick aluminum or steel trays, and they bypass PFAS exposure routes common in modern ceramic non-stick coatings. They are heavier and require slightly more maintenance than disposable or bare aluminum options. Le Creuset's enamel finish is considered more durable than budget enameled alternatives and less prone to chipping.
If you buy it
Inspect the enamel coating for chips or cracks before first use and periodically thereafter; damaged enamel can expose cast iron underneath, which may then rust or leach. Hand wash and avoid thermal shock (rapid temperature swings). Do not use on very high heat continuously; enamel remains stable well above typical oven temperatures (up to 500F regularly). Replace if chipping becomes extensive, as the protective barrier is then compromised.
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.”
Enamel coating degradation and chipping
Vitreous enamel is durable but can chip with impact or thermal stress. Le Creuset's quality reduces this risk, but once compromised, bare cast iron is exposed and can rust or potentially leach iron at higher levels. This is a use and maintenance issue, not a manufacturing defect on record.
Lead or cadmium in enamel glaze
No recalls or testing reports indicate lead or cadmium in Le Creuset enamel coatings. Modern vitreous enamels used by premium manufacturers typically comply with food contact regulations, but proprietary formulation data is not publicly available for independent verification.
Aluminum leaching
This product is cast iron, not aluminum, so aluminum leaching does not apply. The enamel coating prevents direct contact between iron and acidic foods, mitigating typical cast iron leaching concerns.
Teflon-type coating/perfluorinated fume release
Vitreous enamel does not contain Teflon-type coating or release fumes when heated to typical baking temperatures. This is a key safety advantage over Teflon-coated aluminum or steel muffin trays.
Heavy metal migration from enamel pigments
Enamel coatings can include colored pigments; in rare cases, poorly formulated pigments have contained or leached heavy metals. Le Creuset's brand reputation and regulatory compliance in EU/US markets make this unlikely, but proprietary pigment data is not disclosed publicly.
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.
