Never sear in a nonstick pan. Searing requires high heat, and you cannot use high heat with a nonstick pan. Additionally, you want to steer clear of acidic food (think tomato sauces or wines) and nonstick cooking sprays. The acid wears away the coating, and the nonstick sprays build up a residue that is hard to remove.
Professional chefs typically do not use nonstick cookware because it is not as durable as other types of cookware and can scratch or chip easily. Additionally, nonstick coatings can deteriorate over time, which can affect the taste and safety of the food being cooked.
Teflon: Some nonstick pans are sealed with a Teflon coating that can contain PFOA (perfluorooctanoic acid) or PTFE (Polytetrafluoroethylene), which can create toxic fumes when heated.
Signs That Reveal It's Time to Get Rid of Old Cookware
Here are some important old cookware details to look for: Nonstick cookware is scratched or pitted. Pan bottom is warped and doesn't sit flush on the cooktop. This will cause uneven cooking.
We advise replacing your nonstick pans whenever the coating starts to degrade or is scratched—or about every three to five years.
Damaged Non-stick Pans Should Not Be Used
While modern non-stick pans are quite safe when used properly, be careful not to use these when the coating is damaged. For example, the coating could be damaged due to long time usage, or abrasion or scratching by hard objects during cooking and washing.
That's why the best nontoxic nonstick cookware is not necessarily a piece of PFOA- or PFAS-free gear—in fact, we'd argue the best nontoxic “nonstick” pans money can buy are made of stainless steel, cast iron, or carbon steel.
Flaking or peeling: If you see the nonstick surface peeling off or flaking into your food, it's time for a new pan. The coating is breaking down and can end up in your meals.
Bans on Teflon
In 2008, it was outlawed across all of Europe. 2014 saw the United States follow. As part of the Stockholm Convention, PFOA was outlawed internationally in 2019. You could find PFOA in any pots and pans you own that were produced before to the prohibition.

Perhaps the simplest reason that some non stick pans start to stick, especially if the pan isn't very old, is that there's a layer of stuck-on food residue getting in the way. Even the thinnest layer of dried egg white or residual starch from stir-frying potstickers can cause food to stick.
But stainless steel cookware is the most prized and frequently sought-after by professional chefs and serious home cooks alike. Known for its durability and high heat retention, it can achieve an excellent sear or perfect sauté. And it can last a lifetime.
If you wanted to fry an egg or sear a delicate fish, you'd use a nonstick pan. If you want to saute vegetables or whip up a quick stir-fry, you'd use stainless. Why? Because nonstick pans are all about preventing any sort of stick at all.
A: Calphalon stopped manufacturing our nonstick using PFOA back in the third quarter of 2012. We have then since moved to a formula that is completely FDA approved.
In general, you want to replace nonstick pans after five years. But you need to be particularly careful with nonstick cookware produced before 2015, as it may contain PFOA. If your cookware dates back to 2015 and earlier, it's likely time to replace it even if it doesn't contain PFOAs.
“Glass, like Pyrex cookware, is a safe option,” Perko said. “Cast iron is a safe option if NOT frying or using high-temperature cooking. If you have or can use or purchase stainless steel pots and pans, they are healthier choices for long-term/lifetime use.”
Acidic foods like tomatoes can break down the protective coating of your nonstick pan, so recipes like tomato sauce should be made in a different type of skillet. Also, avoid foods with citrus or wine.
Teflon® is a registered trademark of DuPont and a brand name for polytetrafluoroethylene (PTFE) a nonstick finish. While Calphalon cookware features polytetrafluoroethylene-based nonstick finishes, we are not associated with, nor do we use, Teflon® branded products.
“The most nontoxic cookware that you can buy is stainless steel, cast iron or carbon steel; things that don't have a coating on them,” says Alexis Pisciotta, culinary purchasing and events manager and cookware consultant for Food Network.
This staple material is certainly beginner-friendly, but that doesn't mean it isn't just as useful in professional kitchens, too. In fact, non stick cookware is utilized in some of the world's best restaurants, day in and day out.
Then, we removed GreenPan entirely from our list of non-toxic cookware. There were two primary reasons: Competing brands began providing independent laboratory testing to prove their products are non-toxic. We became aware of lawsuits against GreenPan that cast doubt on the company's marketing claims.
Start by mixing together one cup of water, 2 tablespoons of baking powder and ½ a cup of white vinegar. Place the mixture into your non stick pan or cookware and place it on the stove. Allow the mixture to come to the boil and leave it that way for approx 10 minutes.
While most non stick pans will develop light discoloration over time—especially if the surface of your pan is a light color—deep, dark discoloration is a sure sign that your pan's coating is wearing out.
