I like to sear my steaks in a cast iron skillet. They always sear perfectly, never stick, and cleanup is simple. Plus, cast iron pans are basically indestructible and will last you a lifetime. For this recipe, you'll need either a cast-iron pan or stainless steel pan. I do not recommend using nonstick cookware for this recipe. It is not safe to heat a nonstick pan to the temperature needed to properly sear a steak.
