GreenPan Premiere Roaster is the clear pick. All-Clad HA1 Expert Nonstick Roaster with Rack carries a failing PFAS grade, and we never recommend buying a failing product.

Where these two actually differ
- We flag PTFE nonstick coating degradation and fume risk, Coating peeling or flaking into food and PFAS in PTFE nonstick coating and manufacturing residues on the All-Clad and not on the GreenPan.
- We flag Aluminum leaching, Coating degradation and microflaking and Proprietary composition opacity on the GreenPan and not on the All-Clad.
- The All-Clad is Hard-anodized aluminum with PTFE nonstick coating where the GreenPan is Thermolon nonstick coating (proprietary blend, composition not fully disclosed), which is most of the difference in these two grades.
- The gap is 65 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
- We are less certain about the GreenPan grade, at 42% confidence against 78%, because it discloses less.
Both products run through the same public rubric: materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
