If you’re aiming for the lowest-tox cookware, stainless steel and cast iron are the best options. But for those times when you really need a nonstick surface—like frying eggs—a GreenPan can be a helpful tool. While not the cleanest option overall, it’s a better choice than traditional nonstick. If you go this route, choose the Valencia Pro line, which is the most durable and least likely to break down with heat. It’s a good compromise for occasional use when sticking is a concern.
