Greenpan 11 inch x 17 inch Nonstick Cookie Sheet
Skip until GreenPan reveals what nonstick coating is used.
GreenPan markets this cookie sheet as nonstick but won't say what the coating is. The brand promotes PFAS-free lines elsewhere but not this product.

What’s concerning
Non-stick, chemistry undisclosed
Advertised as non-stick but coating type is not explained.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
cookware is a category where PFAS exposure is more common.
Aluminum leaching (substrate exposure)
If the nonstick coating degrades, flakes, or is compromised by scratching or high heat, bare aluminum can contact food. Acidic or salty foods increase leaching risk; long-term consumption of elevated aluminum is associated with neurological concern in vulnerable populations.
Nonstick coating fume release (thermal)
GreenPan does not publicly specify coating chemistry for this model. If the coating contains Teflon-type coating or related Teflon-family coating, temperatures above 500°F trigger decomposition and release of hydrofluoric acid vapors and other fumes. Even if fluorine-free, unspecified coatings may have unknown thermal stability limits.
Coating degradation over time
User reports and cookware durability studies indicate aluminum nonstick sheets lose efficacy within 1-3 years of regular use, especially with hand-washing. Visible wear increases risk of both coating particle ingestion and aluminum exposure.
Absence of chemistry transparency
GreenPan's refusal to publicly disclose the nonstick coating chemistry for this product line prevents independent assessment of PFAS status, thermal safety, and alternative chemical hazards. This opaqueness is itself a red flag in the nonstick cookware category.
The full breakdown
What it's made of and why it matters
This cookie sheet uses an aluminum substrate topped with a proprietary nonstick coating that GreenPan does not publicly specify by chemistry name. Aluminum is reactive at high temperatures, especially in acidic foods, and can leach into food if the nonstick barrier degrades. The unidentified coating is the critical unknown: traditional Teflon-type coating (Teflon) releases toxic fumes above 500°F, while alternative chemistries vary widely in thermal stability and composition transparency. Without disclosure, you cannot verify whether the coating contains legacy PFAS, fluorine-free alternatives, or proprietary blends.
The brand's record and disclosure
GreenPan markets itself as an eco-friendly brand and has publicly committed to removing PFAS and PFOA from cookware, positioning products under names like 'Reserve' and 'Reserve Pro' as PFAS-free. However, the brand does not routinely publish detailed coating chemistry or independent test reports for standard product lines like this 11x17 sheet. No major recalls specific to this model have been recorded, but GreenPan's parent company (Groupe SEB subsidiary) has faced scrutiny over nonstick coating transparency across its brands. Certification or third-party verification for this specific product is not evident in public materials.
How it compares in its category
Cookie sheets span a spectrum from bare aluminum (highest leaching risk, no fume hazard) to ceramic-coated, silicone, or Teflon-type coating alternatives. GreenPan's nonstick option sits in the middle-market segment where marketing claims often outpace chemistry disclosure. Cast iron or stainless steel alternatives eliminate nonstick coating hazards entirely but require seasoning or oil. Brands like Our Place and Caraway offer ceramic coatings with explicit PFAS-free or low-temperature-risk positioning, making them more transparent comparators.
If you buy it
Never exceed 400°F when using this sheet to minimize fume and coating degradation risk; hand-wash only and avoid abrasive scrubbers that compromise the nonstick layer. Inspect the surface regularly for flaking, discoloration, or bare aluminum spots; replace immediately if visible wear appears. Do not use for high-heat broiler applications or prolonged storage of acidic foods (tomatoes, citrus) directly on the surface. Store in a cool, dry place and allow full cooling before washing to extend coating life.
