Also known as a frying pan, this flat-bottomed pan with slanted sides is required for tasks from frying or scrambling eggs to stir-frying and toasting nuts and seeds. A 10- to 12-inch skillet will suit most needs; if omelets are your typical breakfast, an 8-inch skillet will come in handy. Cast iron makes a brilliant skillet, as it’s heavy duty and, with proper care, is nonstick. Alternatively, you can purchase a dedicated nonstick pan to use for egg dishes (don’t bother with nonstick for the rest of your pans). Do not heat nonstick over high heat.
