The real story on traditional non-stick (PTFE)
Let's start with the most controversial category: traditional non-stick coatings, typically PTFE (polytetrafluoroethylene, the generic name for Teflon).
The actual concern: PTFE starts breaking down at temperatures above 500°F, releasing fumes that can cause flu-like symptoms in humans and are toxic to birds. Preheating an empty pan on high can reach these temperatures in minutes.
What's changed: PFOA, a chemical once used to manufacture PTFE, was eliminated from production in 2013 after health concerns emerged. Modern PTFE is made without PFOA. The PTFE itself was never the problem—it was the manufacturing chemical.
The practical reality: PTFE is fine for low-to-medium heat cooking (eggs, pancakes, fish). It's not ideal for searing, high-heat cooking, or any situation where the pan might get very hot. The bigger problem is durability—scratched non-stick releases particles and loses effectiveness.
Our take: PTFE has a place in the kitchen, but it shouldn't be your primary cookware. Use it for what it's good at (delicate cooking) and use more durable materials for everything else.
“PFOA—the problematic manufacturing chemical—was eliminated in 2013. Modern PTFE is different from what caused the original concerns.”
Section Summary
- PTFE degrades above 500°F
- PFOA-free since 2013
- Best for low-medium heat only
Ceramic-coated: the PTFE alternative that isn't perfect
Ceramic-coated pans are marketed as the "non-toxic" alternative to PTFE. Here's the reality:
What it actually is: "Ceramic" non-stick isn't ceramic like your coffee mug. It's a sol-gel coating (silica-based) applied over aluminum. The coating contains no PTFE or PFAS, which is the main selling point.
The durability problem: Ceramic coatings typically last 1-2 years before losing their non-stick properties—much shorter than quality PTFE. Once the coating degrades, you're cooking on exposed aluminum (which some prefer to avoid).
High-heat performance: Ceramic handles higher heat than PTFE, which is good. But the coating degrades faster with repeated high-heat use, which partially negates this advantage.
Our assessment: Ceramic is fine and avoids PTFE if that's important to you. But the shorter lifespan means more waste and higher long-term cost. If you want non-stick without PTFE, it's an option—just budget for replacement.
Section Summary
- Sol-gel coating, not true ceramic
- 1-2 year typical lifespan
- PTFE/PFAS-free is the selling point
Stainless steel: the workhorse that lasts forever
Stainless steel is our top recommendation for most cooking tasks. Here's why:
Material stability: Stainless steel is an alloy of iron, chromium, and nickel. It's non-reactive with most foods, doesn't break down with heat, and has no coatings to degrade. Quality stainless lasts decades.
Nickel considerations: Some people have nickel allergies. If you're sensitive, choose nickel-free stainless (often labeled 18/0 instead of 18/10) or alternate materials. For most people, nickel leaching from cookware is not a meaningful exposure source.
The learning curve: Stainless requires technique—preheating, using enough fat, not moving food too soon. Food can stick if you don't get this right. But the technique is learnable and becomes automatic.
Tri-ply construction matters: Good stainless has an aluminum or copper core sandwiched between stainless layers. This provides even heating (stainless alone heats unevenly). Brands like All-Clad, Cuisinart MultiClad, and Tramontina Tri-ply offer this at different price points.
Investment value: A quality stainless set lasts 20+ years. Amortized over that time, even expensive options are cheaper than repeatedly replacing non-stick.
“A quality stainless steel pan lasts 20+ years. That's decades of cooking without coating concerns or replacement costs.”
Section Summary
- Non-reactive and coating-free
- Requires learning proper technique
- Tri-ply for even heating
- Decades of durability
