The quick answer is, no. A skillet and frying pan are different because of each’s cooking surface and design. There is often confusion because the terms “skillet” and “frying pan” are often used interchangeably. And you can typically use either one of them for many cooking preparations, even if one is better suited for a specific cooking method. Plus, both of these style pans are often made from the same materials and come in similar sizes, so it's easy to understand why there can be confusion. While similar, a skillet is technically a bit deeper and has a slightly larger cooking surface area than a frying pan.
Typically made by adding a non-stick coating to aluminum pans, non-stick frying pans are ideal for cooking delicate foods with a tendency to stick, such as fish, fried eggs, and pancakes. The non-stick coating limits the amount of oils and fats needed to cook food and makes cleanup a breeze since your food won't stick to the pan. Non-stick pans are best used in low to medium heat settings to extend the coating's life. Using a non-stick pan in high-heat applications can damage the coating and cause it to smoke, peel, or flake.
Non-stick fry pans are a preferred choice when cooking on low heat as the external coating suffers damage when exposed to excessive heat. You could use non-stick pans for more delicate meals like crepes, eggs, pancakes and more. However, non-stick cookware cannot produce the searing effect, which means it excludes many of the more popular recipes.
Stainless steel cookware, being the workhorse of your kitchen, can be used for making pretty much anything, including steaks, pork, chicken, and braises.
A multi-ply frying pan with an aluminium core is recommended for the best results when cooking at high temperatures.
