Nonstick cookware excels in certain situations but teflon and nonstick pans have a low-heat design and slick surface, which makes them not the best choice for all foods. When you attempt to develop a proper crust on meat, you’ll end up with pale, gray protein instead of the caramelized golden-brown color you’re after and worst of all, you may be damaging your pans in the process.
The real problem lies in compatibility. Certain ingredients and cooking methods can rapidly degrade nonstick coatings, causing them to chip, flake or wear away prematurely. High heat, metal utensils and abrasive cleaning can all compromise the surface, potentially contaminating your food with coating particles. What starts as a convenient cooking “hack” can quickly become a safety concern and an expensive replacement cycle.
We all love easy cleanup as much as the next bloke, but most of your culinary projects fare better in stainless steel, carbon steel or cast iron. These pans impart high surface heat, giving food char, depth and flavor development. I grilled a career cooking teacher to compile the ultimate nonstick no-go list.
Richard LaMarita is a chef-instructor of Health-Centered Culinary Arts at the Institute of Culinary Education in New York City. LaMarita describes nonstick cookware, including ceramic, as “niche.”
“Scrambled or fried eggs, pancakes and fried tofu are great for cooking in nonstick pans,” LaMarita told me via email. “These sticky foods must come out completely without leaving remnants in the pan. Nonstick pans are popular, easy to clean and convenient, and I recommend every cook have one.”
They’re not designed to handle high heat, be placed in the oven or scrubbed vigorously. The coating that makes a pan nonstick can deteriorate faster when confronted with certain foods or cooking techniques.
So, what foods should never be cooked in nonstick cookware? Here’s what Chef LaMarita says.

1. Most meat and fish
Getting a proper sear on steak, pork chops, chicken or fish is next to impossible in a nonstick pan.
First are foods that require or desire searing on the outside. When you’re looking for a deep, caramelized crust with good color, such as on a steak, chicken breast, or a piece of salmon, you won’t get the color you want from a nonstick pan. Nonstick is not made to tolerate the high heat required to achieve the desired crust, and its surface is not geared toward developing that crust because of the coating on the pan.
2. Most vegetables
Cast iron is ideal for cooking vegetables.
Much like meat, vegetables need a little char for maximum flavor, and you just won’t get it with a nonstick pan. For zucchini, carrots, onions, asparagus and bok choy, reach for a stainless-steel or cast-iron skillet for best results.
3. Caramelized food
A cast-iron skillet or stainless-steel pan is best for properly caramelizing an onion or creating a fond (leftover bits of caramelized food).
Do you know about “fond?’ It’s the caramelized, crusty bits of food left on the pan after searing, and it’s the key to big flavor (and happiness). Fond is used to make pan sauces, searing items first, then picking up those beautiful, tasty bits of food and incorporating them into the sauce. For making fond, a nonstick pan will not serve you. There is simply not enough surface heat.
4. Highly acidic foods
High-acid foods such as tomatoes and wine- or vinegar-based sauces can corrode the surface of a nonstick pan.
Cooking highly acidic foods in nonstick pans is not a good idea. Acidic foods include a tomato sauce, or a dish with a high ratio of vinegar in the pan, such as a braised cabbage, or if there is lemon juice in the cooking process. “Ratatouille is one dish I wouldn’t cook in a nonstick,” LaMarita says. “The acids in this recipe and others will corrode the delicate nonstick surface over time.”
5. Stir-fry, soups, sauces
Recipes that require constant stirring or whisking such as Chinese stir-fry or a delicate sauce are not good candidates for a nonstick skillet.
Along the same lines of wearing down the surface, refrain from cooking foods or dishes that require a fair amount of stirring. A stir-fry, sauce or a dish that demands a lot of tossing and mixing could wear down the surface quickly. “I find that nonstick surfaces wear down eventually, even with proper use, so why speed up that process?”
