A skillet is a versatile cooking pan typically made of cast iron, stainless steel, or non-stick materials. It features a flat bottom and low, flared sides, making it ideal for frying, sautéing, and searing a variety of foods. Skillets come in various sizes and can be used on the stovetop or in the oven, depending on the material and design. Many cooks prefer using a cast iron skillet because it retains heat well and can develop a natural non-stick surface when seasoned properly. Skillets are often used for preparing dishes like omelets, stir-fries, and pancakes, making them a staple in many kitchens.
