There are three types of skillets that every cook should have: stainless, nonstick and cast-iron. Nonstick skillets allow you to use less oil, and cook delicate foods like eggs without fear of sticking. Be sure to look for a nonstick skillet made without PTFE and PFOA: these pans are marketed as “green” or “eco-friendly” and have coatings that won’t break down when used over high heat. Cast-iron skillets are a tried-and-true favorite because you can cook with them over high heat and put them in the oven safely. And a stainless skillet made out of heavy material, which conducts heat evenly and will last for years, is a worthwhile investment. It’s your go-to pan for everything from quick sautéed vegetables to seared pork chops.
