NS Pro Nonstick Cookware Square Griddle
Avoid if PFAS avoidance is a priority; traditional Teflon-type coating nonstick carries PFAS concern.
All-Clad's NS Pro line uses conventional Teflon-type coating-based nonstick coating, a Teflon-family coating typically containing PFAS. The brand makes no public disclosure about PFAS content or safer alternatives.

What’s concerning
PTFE / Teflon confirmed
Contains Teflon-type coating, also called Teflon, a type of PFAS.
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Teflon-type coating thermal decomposition and fume release
Teflon-type coating-coated cookware is documented to release fluorine-containing fumes (including carbonyl fluoride) above 500°F. While acute polymer fume fever is rare in home kitchens, it can occur with careless overheating or preheating on high. All-Clad does not provide thermal limits or fume-test data for the NS Pro.
Coating degradation and flaking
Teflon-type coating coatings degrade with age, mechanical abrasion (metal utensils, dishwashers), and thermal cycling. Once flaking begins, ingestion of microcoatings and increased fume risk on reheating become concerns. No durability or wear-life data is published for the NS Pro griddle.
Aluminum leaching from substrate
If the aluminum substrate is exposed (through coating damage or at edges), acidic or alkaline foods may promote aluminum leaching. The exact substrate construction and coating adhesion strength for the NS Pro are not disclosed, making risk assessment difficult.
Off-gassing and odor during early use
New Teflon-type coating cookware sometimes releases odors during initial heating, attributed to residual processing chemicals or coating stabilizers. This is typically mild but indicates volatile emissions and should prompt ventilation and lower heat settings until odor ceases.
Lack of independent safety certification
The NS Pro griddle carries no third-party certification (e.g., GREENGUARD) for low-emission or PFAS-free claims. All-Clad's compliance relies on FDA food-contact regulations, which do not mandate PFAS disclosure or thermal-stability testing.
The full breakdown
What it's made of and why it matters
The NS Pro griddle uses a Teflon-type coating-based Teflon-family coating nonstick coating bonded to an aluminum or steel substrate. Teflon-type coating (polytetrafluoroethylene, also known as Teflon) is stable at normal cooking temperatures but can decompose when exposed to high heat, releasing fluorine-containing fumes. All-Clad's specific formulation details are not publicly disclosed, so the exact thermal stability profile and any additives remain unknown. This opacity matters because older Teflon-type coating coatings and some modern variants carry higher risks of fume release.
The brand's record and disclosure
All-Clad does not publicly disclose PFAS content, coating composition, or testing protocols for its nonstick cookware. The brand has not issued statements about PFOA phase-out timelines or alternative formulations. No major recalls specific to Teflon-type coating fume hazards or coating degradation have been widely documented for this product line, but the absence of disclosure leaves consumers without assurance of safety improvements. All-Clad's silence contrasts with competitors who now market PFOA-free or ceramic alternatives.
How it compares in its category
Traditional Teflon-type coating griddles remain common in the mid-to-premium market but face growing competition from ceramic, anodized aluminum, and stainless steel alternatives. All-Clad's nonstick offering is positioned as a professional-grade product, implying durability, but does not differentiate itself via PFAS or thermal-safety transparency. Competitors like GreenPan and Caraway now emphasize ceramic or Teflon-type coating-free coatings; All-Clad has not repositioned the NS Pro line toward these safer alternatives.
If you buy it
Never heat above 500°F; use medium heat for most tasks and always ensure adequate ventilation (range hood on). Replace the griddle immediately if the nonstick coating chips, flakes, or shows visible wear, as damaged Teflon-type coating increases fume risk. Hand-wash only; avoid metal utensils and high-temperature dishwashers, which accelerate coating degradation. Preseason on low heat and monitor it closely during the first few uses for any off-gassing odor, which indicates thermal stress.
