GreenPan Premiere Roaster
Named ceramic non-stick coating, with a brand PFAS statement we have not verified.
GreenPan says its Thermolon coated food contact surface is free of PFAS, including Teflon-type coating and PFOA. We record that as an unverified brand claim. Its record describes a non-stick coating of unstated type, which is still counted.
Brand says: “GreenPan says its Thermolon coated food contact surface is free of PFAS, including PTFE and PFOA.”
We flunk more products than we pass. This one earned its grade. How we grade
Material
Thermolon nonstick coating (proprietary blend, composition not fully disclosed)
Brand disclosure
Brand claims PFAS-free
Lab data
No public lab test
What’s concerning
Disclosed non-fluorinated coating
Coating is named and the brand states it is made without PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Aluminum leaching
If the base metal is aluminum, roasting acidic foods (tomatoes, vinegar, citrus) at sustained high heat could theoretically increase leaching, though risk is low with an intact ceramic topcoat. Base metal composition is not publicly specified.
Coating degradation and microflaking
User reports on retail sites document occasional peeling or flaking after extended use, particularly if scratched or exposed to abrasive cleaning; integrity loss may release coating fragments into food.
Proprietary composition opacity
Thermolon's exact mineral formulation is not disclosed, preventing independent verification of all trace elements or processing aids that may be present in the coating.
What’s reassuring
Brand-stated PFAS-free
The brand states this product is PFAS-free. We have not verified the claim.
Teflon-type coating fume risk
GreenPan explicitly formulates Thermolon without Teflon-type coating; no fume incidents reported for this coating at normal roasting temperatures.
Lead
No lead or cadmium contamination has been reported for Thermolon coatings; brand claims PFAS-free status suggests avoidance of heavy metal stabilizers typical in older ceramic glazes.

What it's made of and why it matters
GreenPan Premiere Roaster uses Thermolon, a proprietary ceramic-reinforced nonstick coating that GreenPan describes as Teflon-type coating-free and PFAS-free. The underlying material is steel or aluminum (GreenPan does not fully disclose the base metal in public specs). Thermolon is inorganic and ceramic-type, designed to avoid the polymer chemistry that creates fume risk in traditional Teflon-type coating coatings. The exact mineral composition remains proprietary, limiting independent verification of all components.
The brand's record and disclosure
GreenPan has made explicit PFAS-free claims across its product line and holds some third-party certifications (e.g., Greenguard). However, the full chemical composition of Thermolon is not publicly disclosed, making complete ingredient verification impossible. No major recalls or contamination incidents for Thermolon cookware have been reported in public safety databases. The brand has faced some skepticism from independent analysts about the completeness of their transparency, but no substantiated safety violations are on record.
How it compares in its category
Thermolon roasters sit in the mid-premium segment, competing against traditional Teflon-type coating nonstick (higher fume risk at high heat) and ceramic-coated cast iron (better durability, heavier). Thermolon coatings are generally more scratch-resistant than ceramic enamels but less durable than seasoned cast iron over decades. For roasting specifically (frequent oven use, moderate to high temps), this coating performs comparably to established alternatives without the chemical baggage of Teflon-type coating.
If you buy it
Keep heat below 400°C (750°F) to avoid any potential coating degradation; roasting typically operates well below this. Hand-wash or use low heat on dishwasher cycles to extend coating life (typically 3-5 years with care). Replace the pan if you notice visible peeling, chipping, or discoloration that spreads. Store with soft liners to prevent scratches, and avoid metal utensils that can abrade the surface.
