PFAS in Cookie Sheets, Where Ceramic Grades Well and Nonstick Steel Does Not

This category splits harder than almost any other in our database, and there is very little in the middle. Ceramic nonstick baking sheets from a brand making a public PFAS statement grade 70 out of 100. Conventional nonstick steel sheets, where the coating is described only as nonstick with no chemistry named, grade 15, and nine of the fifteen graded products sit there. Two All-Clad sheets grade 5, because All-Clad says its nonstick contains PTFE.

Based on available materials and data, the GreenPan GreenLife Ceramic Nonstick Cookie Sheet leads the category at 70. At the other end, both All-Clad Pro-Release sheets grade 5, because All-Clad says its nonstick contains PTFE. We graded 15 sheets, and the spread runs from 70 to 5. Below we break down the graded sheets so you can see where each lands and why.

How we graded these sheets

Every grade in this article is a model-based estimate built from publicly available materials disclosures, manufacturing descriptions and brand documentation, not a lab test performed by our team. A high score means lower concern based on reviewed sources, never PFAS-free and never safe. No product in this category carried published independent lab data, so where a brand claims a coating contains no PFAS we record that as a brand-stated claim and grade accordingly. A named coating with a brand statement, against an unnamed coating with no statement, is what separates the 70s from the 15s. The recorded concerns across the category were coating degradation and flaking, undisclosed coating chemistry, and a lack of transparency on nonstick composition. You can compare any specific sheet using our PFAS product finder.

A note on the Calphalon claim, stated precisely

The Calphalon sheet is sold under a name that includes the phrase PFA free. PFA is one fluoropolymer, so that phrase is not a statement about the wider PFAS family, which covers thousands of substances, and we found no PFAS statement from Calphalon for its cookie sheets. The sheet grades 55, the bakeware baseline of 30 plus 15 because Calphalon says nothing about PFAS for it. An earlier version of this guide said our record logged a brand PFAS-free claim for this sheet and graded it 80. That was wrong, and we corrected it on 17 September 2026.

The Good tier, 55 to 70 out of 100

Four products sit in this tier. Three GreenPan sheets grade 70, and the Calphalon sheet covered above grades 55.

GreenPan GreenLife Ceramic Nonstick Cookie Sheet and the GreenPan Premiere Ovenware Half Sheet Pan both grade 70, as does a second GreenLife cookie sheet listing. GreenPan says its Thermolon coated food contact surface is free of PFAS, including PTFE and PFOA. We have not verified that, and we found no third-party certification for it. The 70 is the bakeware baseline of 30, plus 10 because the sheets have a coating, minus 10 for GreenPan's statement. These sheets graded 90 until 17 September 2026, when we began grading every ceramic non-stick as a coating instead of giving it a safe material credit. Cons include that the statement is the brand's own, and ceramic nonstick coatings are known to lose their release performance faster than fluoropolymer ones, which is a durability trade-off rather than a chemical one.

The Bad tier, 15 and 5 out of 100

Nine products share the grade of 15, which makes an unnamed coating the dominant outcome in the category rather than an exception.

The All-Clad Pro-Release Bakeware Cookie Sheet and its half sheet pan counterpart are the most notable entries. Pro-Release is a proprietary name rather than a description, but All-Clad's own disclosure says its nonstick contains PTFE, so both sheets grade 5, the bottom of our scale. They graded 15 until 17 September 2026, when we applied that disclosure.

Six Cuisinart listings and three Rachael Ray listings complete the tier, all described as steel or aluminized steel with a nonstick coating whose type is not given. One of them, the Cuisinart 5-Piece Stackable Ceramic Nonstick Bakeware, is worth separating out because it is called ceramic and still grades 15. That is the clearest evidence in this category that the word ceramic on a label is not what earns a grade. Disclosure is. There are no pros to highlight from a PFAS grading standpoint across this tier. The con is the same throughout.

What to avoid

• Sheets whose coating is named only as nonstick, with no chemistry stated. That is nine of the fifteen products here.
• Sheets from a line the maker discloses as PTFE, if avoiding fluoropolymers is your aim. Two All-Clad sheets here.
• Reading the word ceramic on a label as sufficient. A Cuisinart product called ceramic nonstick grades 15 because nothing backs the word, while GreenPan's ceramic sheets grade 70 because GreenPan names its coating and makes a PFAS statement.
• Treating a claim about one named compound as a claim about PFAS generally, which is the distinction we set out above for the Calphalon sheet.
• Assuming a premium brand grades better. All-Clad is the most expensive name in this category and sits at the bottom of it.

An alternative worth knowing about is skipping the coating entirely and using a plain sheet with a liner. Our parchment paper and baking liners guide covers which liners grade well, and our bakeware category covers related pans with their own grading. The PFAS hazard page explains why undisclosed fluoropolymer coatings attract scrutiny.

Our pick

Based on available materials and data, the GreenPan GreenLife Ceramic Nonstick Cookie Sheet is our top pick at 70 out of 100, as a named ceramic coating backed by a brand statement rather than an unnamed one. For a half sheet format the GreenPan Premiere Ovenware Half Sheet Pan carries the same grade. If you would rather not rely on any coating claim at all, an uncoated sheet used with a plain silicone mat or uncertified parchment is the option our data supports most directly, since it removes the undisclosed coating from the equation entirely. These are estimates built from disclosed materials and brand statements, not laboratory proof, and no product here is being called PFAS-free or safe by us.

FAQ

Does ceramic nonstick mean no PFAS?

Not on its own. In this category a Cuisinart product described as ceramic nonstick grades 15 out of 100 while GreenPan's ceramic sheets grade 70, and the difference is that GreenPan makes a public claim about its coating while the Cuisinart listing discloses nothing. The word on the label is not what our model responds to.

Why do All-Clad sheets grade so low?

Because All-Clad says its nonstick contains PTFE, a fluoropolymer in the PFAS family. A PTFE coating adds 50 points and the missing PFAS-free statement 15, on top of the baseline of 30. It is an assessment of disclosure, not a laboratory finding about the product.

Is an uncoated sheet with parchment a better option?

It removes the undisclosed coating question, which is what drives almost every low grade here, but it moves the question to the liner instead. Our separate guide on parchment and baking liners covers how those grade, including which ones carry certifications.

Should I be worried about health effects from a lower-graded sheet?

Any discussion of PFAS and health in our guides describes association, not proven causation, and grades measure estimated chemical concern based on materials and disclosure, not a medical risk assessment for any individual. If you want to reduce potential exposure in a kitchen, cross-reference products using our PFAS product finder alongside categories like cookware.
