A non-stick skillet is a type of frying pan coated with a material that prevents food from sticking during cooking. This coating, often made from polytetrafluoroethylene (PTFE), allows for easy food release and simplifies cleanup. Non-stick skillets are popular for cooking delicate foods like eggs and pancakes, as they require less oil or butter. These skillets come in various sizes and materials, including aluminum and stainless steel bases. They are suitable for low to medium heat cooking and are often dishwasher safe. However, it's important to use non-metal utensils to avoid damaging the non-stick surface.
