Le Creuset Signature Deep Square Grill
Lower PFAS concern; enameled cast iron is inherently nonstick without Teflon-family coating coatings.
Le Creuset's Signature Deep Square Grill is enameled cast iron, a traditional material without applied nonstick Teflon-family coating coatings. The brand does not market PFAS avoidance or publish PFAS testing, but the product category itself carries lower inherent risk. No public lab data or recalls found.

Why this grade
Category baseline
cookware is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
The Le Creuset Signature Deep Square Grill is cast iron coated with a vitrified enamel glaze, typically a glass-like surface fused to the iron at high temperature. This enamel layer acts as a permanent non-stick surface and corrosion barrier without requiring any Teflon-family coating (Teflon-type coating) or other synthetic coatings. The enameling process creates a chemically stable, non-leaching surface that does not degrade into particles under normal cooking conditions.
The brand's record and disclosure
Le Creuset is a heritage French cookware manufacturer with a well-documented 90+ year track record of enameled cast iron production and consistent product warranties (typically lifetime for manufacture defects). The company does not publicly market PFAS-free status because enameled cast iron is inherently PFAS-free by design. No major recalls or documented safety failures linked to enamel leaching have been established for Le Creuset cookware in independent testing or regulatory databases.
How it compares in its category
Enameled cast iron grill pans like this sit at the safer end of the cookware spectrum compared to non-stick skillets with Teflon-type coating or ceramic coatings prone to flaking. Alternative materials (bare cast iron, stainless steel, aluminum) lack the non-stick benefit without equivalent durability; non-stick competitors carry documented Teflon-type coating off-gassing and degradation risks. Le Creuset's enamel formulation is thicker and more durable than budget competitors, reducing the risk of chipping that could expose underlying iron.
If you buy it
Avoid sudden temperature shock (do not transfer from stovetop directly to cold water) as thermal stress can cause enamel crazing or chipping over decades of use. Do not use metal utensils repeatedly on the cooking surface; wood or silicone minimizes micro-damage. Hand wash only; dishwasher cycles can degrade the enamel seal over time. If enamel chips and exposes cast iron, the exposed area will rust; repair kits exist, but replacement is practical if damage is extensive.
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 documented testing has revealed lead or cadmium leaching from Le Creuset enameled cookware in peer-reviewed studies or regulatory action. Vitrified enamels are chemically stable and do not leach heavy metals under standard cooking conditions.
Enamel chipping and cast iron exposure
Aluminum leaching
This product is cast iron, not aluminum. Not applicable.
Teflon-type coating/non-stick coating degradation and fume inhalation
Enameled cast iron does not use Teflon-type coating or other synthetic non-stick coatings. The enamel glaze is inert and does not off-gas Teflon-family coating fumes even at high temperatures (safe to 300C+).
Coating adhesion and particle shedding
While vitrified enamel is very durable, repeated thermal stress or impact can cause small enamel flakes to enter food. Risk is low with careful use, but not zero. Chipped areas should be repaired or the pan replaced to prevent continued flaking.
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.
